Answer 1

Alex didn't answer it correctly, because if you see the part where it says  -5x - (-7...

it has two minus signs, one in front of the parantheses, and one behind it.

Since they cancel each other, the 7 would be positive.

6x + 9 =27 (I need help please )

Answers

Answer:

X=3

Step-by-step explanation:

6x=27-9

6x=18/6

x=3

Answer:

x=3

Step-by-step explanation:

Alrighty lets begin.

First, subtract 9 from 9 and from 27. Your equation will look like:

6x=18

Now, divide 6 from 6x and from 18. It would look like:

6x/6 = 18/6

Then cancel out the 6's.

And finally, simplify 18/6 and you get 3.

Your answer is x = 3

A 3. What is the midpoint M given S(-8,-6) and T(4, 12)?
0 (-2,3)
O (7,8)
0 (-6, -9)
0 (-1,-4)

Answers

Answer:

The answer is ( - 2 , 3)

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(-8,-6) and T(4, 12)

We have

[tex]M = ( \frac{ - 8 + 4}{2} \: , \: \frac{ - 6 + 12}{2} ) \\ = ( - \frac{4}{2} \: , \: \frac{6}{2} )[/tex]

We have the final answer as

( - 2 , 3)

Help 33-37 please will score as brainliest

Answers

Answer:

See below

Step-by-step explanation:

Quadratic function is in general form of:

y = ax^2 + bx + c

The function has a minimum if a > 0 and maximum if a < 0

The minimum or maximum point is a vertex of the graph

A vertex is the point x = -b/2a

When b = 0, the min or max point equals to value of c.

33. It has maximum of -134. It has minimum of 735. It has minimum at x = - 8/4 = -2

f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1

36. It has maximum at x = -18/2(-3)= 3

g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22

37.  It has minimum at x = - 6/(2*3/2) = - 2

f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?

Answers

Answer:

96

Step-by-step

the distance from the amusement to jack's home is x (mile, x>0)

jack's family went to the amusement park at: 9 + x/60

On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph

they left the amusement park at: 20 - x/40

have the following equation:

(20 - x/40) - (9+ x/60) = 7

⇔ 4 = x/40 + x/60

⇔ x = 96

so the distance from the amusement park to jack's home is 96 mile

                                         

Distance of amusement park from Jack's home = 96 miles

Let the distance from Jackie's house to the amusement park be x.

She drove at a speed of 60 mph to get to the amusement park.

Now, formula for time is;

Time = distance/speed

Time; t1 = x/60 hours

Now, we are told she spent 7 hours at the park. Thus; t2 = 7 hours

On her way back home from school, we are told she drove 20 mph slower than her speed in the morning. Thus, speed = 60 - 20 = 40 mph

Thus; time; t3 = x/40

Now, she left home by 9 am and got home by 8pm same day. This is a total of t = 11 hours

Thus;

t1 + t2 + t3 = 11

Plugging in the relevant values;

(x/60) + 7 + (x/40) = 11

Rearrange to get;

(x/60) + (x/40) = 11 - 7

(x/60) + (x/40) = 4

Multiply through by 120 to get

2x + 3x = 480

5x = 480

x = 480/5

x = 96 miles

Solution (1) :-

In this figure ∠7 and ∠3 are alternate interior angles . Alternate interior angles in two parallel lines with a transversal will always be equal . Since ∠7 is congruent to ∠3 , we can say that line m and line n are parallel lines .

Therefore :-

The lines are parallel because the alternate interior angles in them are congruent .

Solution (2) :-

Given :-

m3 = ( 15x + 22 )°

Then , m∠3 will be equal to :-

x = 8

= 15 × 8 + 22

= 120 + 22

m∠3 = 142°

m1 = ( 19x - 10 )°

= 19 × 8 - 10

= 152 - 10

m∠1 = 142°

angle 1 and angle 3 are corresponding angles , which means their value will be equal if they are present on two parallel lines with a transversal . As their values are equal we can say that line m and line n are parallel .

Therefore :-

Yes , the lines are parallel because the corresponding angles in them are equal .

Solution (3) :-

∠7 and ∠6 are interior angles on the same side of transversal , which means their angle su, will be equal to 180° . But since their values are equal these two lines are not parallel .

Therefore :-

∠7 and ∠6 are interior angles on the same side of transversal , so their sum will be equal to 180° . But since that is not the case in the lines shown above , those lines are not parallel lines .

Solution (4) :-

Given :-

m2 = ( 5x + 3 )°

x = 14

= 5 × 14 + 3

= 60 + 3

= 63°

m∠3 = ( 8x - 5 )°

= 8 × 14 - 5

= 112 - 5

= 107°

We know that the sum of angle 2 and angle 3 will be equal to 180° if they are on two parallel lines as they are interior angles on the same side of transversal .

As :-

∠2 + ∠3 ≠ 180°

63° + 107° is not equal to 180° ,

Therefore :-

These lines are not parallel as the sum of their interior angles on the same side of transversal is not equal to 180°.

Solution (5) :-

Given :-

m8 = ( 6x - 1 )°

x = 9

= 6 × 9 - 1

= 54 - 1

= 53°

m4 = ( 5x + 3 )°

= 5 × 9 + 3

= 45 + 3

= 48°

angle 8 and angle 2 are vertically opposite angles , which means m∠8 = m∠2 .

m∠2 = 53°

As ∠2 and ∠4 are corresponding angles their value will be equal , if they are on parallel lines .

Since angle 2 , angle 8 and angle 4 are not equal these lines are not parallel lines .

Therefore :-

The lines are not parallel as their corresponding angles are not equal .

Solution (6) :-

Angle 5 and angle 7 are corresponding angles they will be congruent when on parallel lines .

As , m∠5 ≅ m∠7 these lines are parallel .

Therefore :-

These lines are parallel lines as their corresponding angles are equal .

Solution (7) :-

Angle 1 and angle 7 are vertically opposite angles , which means their angle measure will be equal . As angle 7 and angle 5 are corresponding angles their angle measure will also be equal .

Since m∠5 ≅ m∠7 , these lines are parallel .

Therefore :-

These lines are parallel lines as their corresponding angles are equal .

Solution (8) :-

Here , the value of x is the same .

Which means :-

m∠2 = x + 15° is greater than m∠6 = x + 10°

Angle 2 and angle 6 are alternate interior angles , their values should be equal . But since their values are not equal , the lines on which they reside are not parallel .

Therefore :-

These lines are not parallel as their alternate interior angles are not equal .

Solution (9) :-

It is given that angle 1 and angle 3 are supplementary angles . It is also clear that angle 1 and angle 2 are a linear pair , which means their angle sum will be equal to 180° . Also , angle 3 and angle 2 should be equal since they are the supplement of the same angle . Angle 2 and angle 3 are also corresponding angles . Since corresponding angles in two lines with a transversal will be equal and in these two lines the corresponding angles are equal , these lines are parallel lines.

Therefore , JK // HI as their corresponding angles are equal .

7(x - 3) = 4(x + 5)
HELP ASAP

Answers

Step-by-step explanation:

7(x - 3) = 4(x + 5)

7x - 21 = 4x + 20

3x = 41

x = 13.67

Let's solve your equation step-by-step

7(x-3)=4(x+5)

Step 1:Simplify both side of the equation

7(x-3)=4(x+5)

(7)(x)+(7)(-3)=(4)(x)+(4)(5) (Distribute)

7x+-21=4x+20

7x-21=4x+20

Step 2:Subtract 4x from both sides

7x-21-4x=4x+20-4x

3x-21=20

Step 3: Add 21 to both sides

3x-21+21=20+21

3x=41

Step 4: Divide both sides by 3

3x/3 =41/3

Answer: x=41/3

7. Mark needs to move to a new apartment and is trying to find the most affordable moving truck. He will only need to truck for one day. After checking the U-Haul website, he finds that he can rent a 10 - ft truck for $20.95 a day plus $1.89 per mile. He then checks the Public Storage website and finds the charge to be $37.95 a
day plus $1.19 per mile for the same size truck. Determine the number of miles for which the cost to rent from either company would be the same. Round the answer to the nearest mile (5 points).

Answers

Answer:

24 miles

Step-by-step explanation:

Let the number of miles = x.

U-Haul:

1.89x + 20.95

Public Storage:

1.19x + 37.95

Set the costs equal and solve for the mileage, x.

1.89x + 20.95 = 1.19x + 37.95

0.7x = 17

x = 24.29

b) 60 degrees
c) 120 degrees
d) 135 degrees

Answers

Answer:

d) 135°

Step-by-step explanation:

x ; y =supplementary =>

=> x + y = 180

x = 3y

replace x

3y + y = 180

4y = 180

y = 180 : 4

y = 45°

x = 3y

x = 3×45°

x = 135°
