Evaluate this expression when x is 50

-6x+150

Answer:

y = - 2x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{2}[/tex] x + 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2

The perpendicular line passes through the origin ⇒ c = 0

The equation of line L₂ is

y = - 2x + 0 , that is

y = - 2x

The perimeter of the isosceles triangle is 88.

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, equilateral, isosceles and so on.

From the diagram, two sides of the triangle are equal, hence it is an isosceles triangle, hence:

10a - 9 = 14a - 25

4a = 16

a = 4

10a - 9 = 10(4) - 9 = 31

6a + 2 = 6(4) + 2 = 26

Hence the perimeter of the triangle = 31 + 31 + 26 = 88

Hence the perimeter of the triangle is 88.

Answer:

I believe its D

Step-by-step explanation:

its the same line just 10 units down, meaning it would be parallel and pass thru that point.

Answer:

I'm not supposed to help you if you are taking a test, but the answer would be letter D which is 1/2x

Step-by-step explanation:

Remember, parallel lines have the same slope. The only line that has the same slope as y = 1/2x + 10 is y = 1/2x

Answer:

  Bob

Step-by-step explanation:

The "steepness," or slope, of the mountain is the ratio of height to horizontal distance to the base:

  Joe's mountain slope = 1200/1500 = 0.8

  Bob's mountain slope = 900/1000 = 0.9

Bob's mountain has a greater slope than Joe's. Bob climbed the steeper mountain.

first you combine like terms

25m + 43,200 = 45,675 - 200m

then you add 200m to both sides

225m + 43,200 = 45,675

then you subtract 43,200 from both sides

225m = 2,475

then you divide both sides by 225

m = 11

Answer:

The measure of angle Q is 133 degrees

Step-by-step explanation:

(x + 13) + (10x + 13) + (2x - 2) = 180 //There are 180 degrees in a triangle

x + 13 + 10x + 13 + 2x - 2 = 180 //Remove parentheses

13x + 24 = 180 //Combine like terms

13x = 156 //Subtract 24 from each side

x = 12 //Divide to get value of x

10(12) + 13 = Measure of angle Q //We know Q is 10x + 13, since we know what x is 12 from the previous step we'll substitute x for 12

120 + 13 = Measure of angle Q //Multiple 10 and 12

133 = Measure of angle Q

Step-by-step explanation:

The height of flagpole is 24ft.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

Given;

Hypotenuse=26ft

Base=10ft

Now,

Hypotenuse^2=base^2+Height^2

26^2=10^2+h^2

676=100+h^2

576=h^2

h=24

Therefore, by Pythagoras theorem the height will be 24ft.

Answer:

The original cost of the product was $35.68.

Step-by-step explanation:

As Sasha has a discount coupon of 35%, the final amount that he will pay is 65% of the initial value of the product (100 - 35). Thus, 65% of the value is $ 23. Therefore, to determine the initial cost of the product, it is necessary to perform the following calculation:

65 = 23

100 = X

((100 x 23) / 65) = X

2,300 / 65 = X

35.68 = X

Therefore, the initial value of the product was $ 35.68.

I had this on my quiz

Answer:

One hour after  starting

Step-by-step explanation:

Let Teri walk at a rate of 2 miles per hour in time , t + 0.5, since it is 30 minutes ahead and 30 minutes = 0.5 hours, the distance he moves is d = 2(t + 0.5). Also, since Cindy moves at a rate of 3 miles per hour, and starts at time t, the distance d' she moves is d' = 3t.

Now, when they catch each other, the distance moved is the same.

So, d = d'

2(t + 0.5) = 3t

expanding the brackets, we have

2t + 2 × 0.5 = 3t

2t + 1 = 3t

collecting like terms, we have

3t - 2t = 1

simplifying, we have

t = 1

So, Cindy will catch Teri one hour after starting.

Answer:

x = 2

y = -1

Step-by-step explanation:

8x + 2y = 14

2x + y = 3

In order to find the number x represents, you have to make the number of y for both equations the same. So:

8x + 2y = 14

(×2) 4x + 2y = 6 (×2)

Then, you can cancel the y off both equations, which will leave:

8x = 14

4x = 6

To find 4x, you have to find the difference between both equations, so you have to:

14 - 6 = 8

Now that the actual number 4x represents is 8, so:

4x = 8

(÷4) x = 2 (÷4)

Now to find y, substitute the letter x with 2:

2x + y = 3

2 (2) + y = 3

4 + y = 3

4 - 3 = -y

1 = -y

(× -) -1 = y (× -)

Answer: x = 2

              y = -1

Hope this helps!  :)

Answer:

Step-by-step explanation:

The answer is B. His budget is $250 so it has to be less than or equal to. $60 a crew member (x = the crew members) and $45 to use the forklift, so $60x + $45 is less than or equal to $250

Answer:

B is the correct answer.

Step-by-step explanation:

According to the problem, the contractor can spend AT MOST $250 a day, meaning $250 is the limit. Therefore, that gives you less than or equal too, or ≤. Next, it costs $45 a day, including $60, which you would add to get the final amount, or +.

Therefore, 60x + 45 ≤ 250
