Difference between (-7x+7) - (-8x-9)

Answer:

  x = 11

Step-by-step explanation:

If we assume that points A, B, and C are on the same line with B between A and C, then we have ...

  AB +BC = AC

  (4x +34) +(6x +6) = 150 . . . . use the given expressions

  10x +40 = 150 . . . . . . . . . . . . collect terms

  10x = 110 . . . . . . . . . . . . . . . .  subtract 40; next, divide by 10

  x = 11

Answer:

False

Step-by-step explanation:

All the angles in a triangle must add up to 180 degrees. Let's test this with the values given:

[tex]111+28+31[/tex]

[tex]= 170[/tex]

These angles only add up to 170°. Therefore, the answer is false, and these measures do not form a triangle.

AB || CD and AC is oblique ;

So : Angle ( BAC ) = Angle ( DCA )

_________________________________

∆ ABC - ∆ ACD :

(1) AB = CD

(2) Angle ( BAC ) = Angle ( DCA )

(3) AC = AC

So According to (1) , (2) , (3) :

∆ ABC =~ ∆ ACD

Well, if two triangles are deposited, all their components are equal peer to peer.

So : AD = BC

Answer:

TAG is described as an acute angle.

Step-by-step explanation:

This is because TAG is an angle that is less than 90 degrees.

Answer:

acute

Step-by-step explanation:

TAG

think of the angle, the gap is small and T is close to G

if it would be right the T would be upright

if it was straight T would lay flat corresponding to G making a line

if it was obtuse the gap would surpass the right angle outward

Answer:

The insulation fee for 175 square feet of carpet is $237.

Step-by-step explanation:

The amount of money, f(x), that it cost to purchase x square feet of the carpet is:

f(x)= 8x

The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have

g(x)=8% of f(x)+125

[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]

[tex]\Rightarrow=0.64x+125[/tex]

The insulation fee for 175 square feet of carpet,

i.e for x=175

[tex]g(x=175)=0.64\times175+125=237[/tex]

Hence, the insulation fee for 175 square feet of carpet is $237.

Answer:

3 and 4

Step-by-step explanation:

Answer:

3 and 4.

Step-by-step explanation:

3^2 = 9

4^2 = 16

So the square root of 12 will lie between 3 and 4 on the number line.

Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.

Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).

Hey there!

Speed (s) = m/hr

Distance = 12 miles

Time = ?

We have,

[tex]t = \frac{d}{s} [/tex]

[tex]t = \frac{12}{1} [/tex]

Therefore, time = 12 hr.

[Note: The speed is 1miles/hr. So, we got time same as the distance]

x = 45

Step-by-step explanation:

[tex]540 + 6x = 810[/tex]

Step 1 : Collect like terms

[tex]6x = 810 - 540[/tex]

Step 2 : Simplify

[tex]6x = 270[/tex]

Divide both sides of the equation by 6

[tex] \frac{6x}{6} = \frac{270}{6} [/tex]

Step 4 : Simplify

[tex]x = 45[/tex]

I hope it helps :)

Answer:

Well...X=45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0

Pull out like factors :-270 + 6x  =   6 • (x - 45)

Solve  :    x-45 = 0::

Add  45  to both sides of the equation:  x = 45

Answer:

x + 3y - 9 = 0

Step-by-step explanation:

(d): x + 3y = 15 -> (d): x + 3y - 15 =0

if (d')║(d)

-> (d'): x + 3y + c = 0

but (d') passes through the point (6;1) => c = -x-3y = -6-3.1 = -9

=> (d'): x + 3y - 9 =0

The equation of the line that passes through the point (6,1) and is parallel to the line (x + 3y = 15) is 3y +x = 9 and this can be determined by using the one-point slope form of the line.

Given :

The line passes through the point (6,1) and is parallel to the line (x + 3y = 15).

The following steps can be used in order to determine the equation of the line that passes through the point (6,1) and is parallel to the line (x + 3y = 15):

Step 1 - Remember that when two lines are parallel then their slopes are equal.

Step 2 - So, the slope of the line that passes through the point (6,1) is -1/3.

Step 3 - So, using the one-point slope form of a line the equation of a line that passes through the point (6,1) and is parallel to the line (x + 3y = 15) can be determined.

Step 4 - The one-point slope form is given below:

[tex](y-y_1)=m(x-x_1)[/tex]

Step 5 - Substitute the values of the known terms in the above equation.

[tex](y-1)=-\dfrac{1}{3}(x-6)[/tex]

3y - 3 = -x + 6

3y +x = 9

Answer:

-11

Step-by-step explanation:

-1/2y=1/2+5

- 1/2 y = 1+10 (by taking lcm)

               2  

 [tex]\frac{-1}{2}[/tex] x 2y = 11

y = -11

[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]

[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]

[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]

[tex]y = \frac{ \: \: 22}{ - 2} [/tex]

[tex]y = - 11[/tex]

The value of y = -11

Therefore :-

[tex] \frac{ - 1}{ \: \: \:2} \times - 11 = \frac{1}{2} + 5[/tex]

Answer:

m = 0

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in numbers:

m = 0 - 0 / -6 - 4

m = 0 / -10

m = 0

Therefore, the slope of the line is 0, meaning it has zero slope.
