50 Pointsanswer This Questions Based On The Graph :-what Does The Point B Represent? -what Is The Unit

Answers

Answer 1

Answer:

1) he will drive 180 miles in 4 hours

2) 45 mph

3) 2 hours

4) 270 miles

Step-by-step explanation:

Number 1:

The point is on (4,180) and since the x is hours and the y is miles. In 4 hours he can drive 180 miles.

Number 2:

For the unit rate we will use the same point (4,180) and put it the y over the x and simplify. [tex]\frac{y}{x}=\frac{180}{4}=\frac{45}{1}=45[/tex] so in 1 hour he can drive 45 miles.

Number 3:

Now for this we should set up an equation [tex]y=45x[/tex]. So they told us if he drove for 90 miles that means we will substitute the y and place the 90 because as I said in number 1 y is miles.

[tex]y=45x\\90=45x\\x=2[/tex]

So it'll take him 2 hours to drive 90 miles.

Number 4:

Now they are telling us how many miles can he drive if he drives for 6 hours. We can use the same equation for this and instead we will be substituting for x since x is hours.

[tex]y=45x\\y=45(6)\\y=270[/tex]

So if he would to drive for 6 hours he can drive 270 miles.

Which linear function represents the line given by the point-slope equation y + 1 =-3(x – 5)?

Answers

Answer:

f(x)= -3x+14

Step-by-step explanation:

the question gives you

f(x)+1=-3(x-5)

the first thing you want to do is distribute the -3 to the (x-5)

f(x)+1=-3x+15

then you going to subtract the 1 and move it to the other side

The leadership class starts a campaign to change the school mascot. The school principal has agreed to change the mascot if two-thirds of the student body plus 1 additional student vote for the change. The required number of votes is 255. How many students attend the school? (Please also write the equation)

Answers

Answer:

254/2=127

127*3=381

381+1=382

Step-by-step explanation:

254/2 because 2/3 of the students is 254 and this is to simplify it

127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them

381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in

The Answer Is: 382

Equation: (254/2)*3+1

Answers

6 and 2 I think lol good luck

The  possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7What is Property of Triangle?

In a triangle, the third side must be greater than or equal to the sum of the other two sides. The length of a triangle's third side is always longer than the sum of any two of its sides.

Given sides are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches.

We know that the third side of a triangle is greater than sum of other two sides.

So, (2 + 3) >4

and, (3 + 4)> 5

and, (5+ 6)>7

Hence, the possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7

Answers

Answer:

  A.  trapezoid

Step-by-step explanation:

The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.

The figure has one pair of parallel sides, so is a trapezoid.

Solving two-step inequalities is much like solving two-step equations. Use
inverse operations to
solve each of the following inequalities.
5x + 8.5 > - 10.3
2x - 10 < 80

Answers

Answer:

1) x>-3.76 2) x<45

Step-by-step explanation:

1) 5x+8.5>-10.3

Isolate the variable

Combine like terms/ subtract 8.5 from both sides

5x>-18.8

Divide by sides by 5

x>-3.76

Remember, if we were dividing or multiplying by a negative number, we would switch the inequality sign, but here we do not.

2) 2x-10<80

Isolate the variable

Combine like terms/ add 10 to both sides

2x<90

Divide both sides by 2

x<45

ABC congruent DEF find the measure of the given angles or the lengths of the given sides​

Answers

Answer:

BC = 8 and EF = 8

Step-by-step explanation:

Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.

Let us solve the question

∵ The two triangles ABC and DEF are congruent

∴ BC = EF

∵ BC = 3z + 2

∵ EF = z + 6

→ Equate their length

∴ 3z + 2 = z + 6

→ Subtract z from both sides

∵ 3z - z + 2 = z - z + 6

∴ 2z + 2 = 6

→ Subtract 2 from both sides

∵ 2z + 2 - 2 = 6 - 2

∴ 2z = 4

→ Divide both sides by 2

∴ z = 2

→ Substitute z by 2 in the length of sides BC and EF to find them

∵ BC = 3(2) + 2 = 6 + 2

∴ BC = 8

∵ EF = 2 + 6

∴ EF = 8

What is the equation of the line that passes through the point (-5, -2) and has a
slope of -6/5

Answers

Answer:

Step-by-step explanation:

you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)

next use  the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope

y-(-2) = -6/5(x-(-2))    ( they are making this tuff with all the minus signs :/ )

y+2 = -6/5(x+2)         ( nice looks better, distribute the -6/5 )

y + 2 = -6/5x -12/5    (move the 2 over )

y = -6/5x - 12/5 -2      ( 2 = 10/5 )

y = -6/5x -12/5 - 10/5    (add the fractions )

y = -6/5x -22/5    

that's in the form of the slope-intercept now  [ y = mx + b ] so you're done :)
