solve for y, 12x-20y=180​

Answers

Answer 1

Answer:

y=35x−9

Step-by-step explanation:

Step 1: Add -12x to both sides.

12x−20y+−12x=180+−12x

−20y=−12x+180

Step 2: Divide both sides by -20.

−20y−20=−12x+180−20

y=35x−9

Answer 2
I think the answer is x=53y+15

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers

Answers

Answer: t 0<t<3

Step-by-step explanation:

Answer:

The correct option is 1.

Step-by-step explanation:

The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.

The value of height and time can not be negative, there the values of h and t must be greater than 0.

The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.

The graph is defined from t=0 to t=3.

Therefore option 1 is correct.

What is LaTeX: m\angle PTQm ∠ P T Q?

line ps intersecting with line qr at point t. angle ptq is x + 28 degrees. angle rts is 2x + 16 degrees.

Group of answer choices

140

40

50

12

Answers

Answer:

B. 40

Step-by-step explanation:

If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)

Given

PTQ is x + 28

RTS is 2x + 16

Since they are both equal, then x+28 = 2x+16

collect like terms

x-2x = 16-28

-x = -12

multiply both sides by -1

-1(-x) = -1(-12)

x = 12

Since ∠ P T Q = x+28, substitute x = 12 into the function

∠ P T Q = 12+28

∠ P T Q = 40

Hence measure of ∠ P T Q is 40°

- If JL = 5x + 2, find JL.

Answers

Answer:

JL= 62

Step-by-step explanation:

27+3x-1=5x+2

3x+26=5x+2

3x+24=5x

24=2x

12=x

now plug in x(which is 12) for JL

5(12)+2

60+2

=62

The measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

JL = 5x + 2

From the line segment:

JL = 27 + 3x - 1

Plug the value of JL in the equation:

5x + 2  = 27 + 3x - 1

After solving:

5x - 3x = 26 - 2

2x = 24

x = 12

JL = 5x + 2

Plug x = 12 in the above equation:

JL = 5(12) + 2

JL = 60 + 2

JL = 62 units

Thus, the measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

The perimeter of a movie screen is 76 meters. It is 24 meters wide. How tall is it? meters​

Answers

Answer:

14

Step-by-step explanation:

the perimeter of a rectangle is : 2W + 2L = Perimeter

2*24 + 2L = 76

48 + 2L = 76

2L = 76 -48

2L = 28

L=14

Answer:

14 meters

Step-by-step explanation:

Assuming the movie screen is a rectangle, there are four sides. Two of those sides are 24 meters. Therefore you would add 24 and 24 to get 48 meters. Then you take 76 and subtract 48. The difference of 76 and 48 is 28. To know how tall the movie screen is you need to divide 28 by two (there are two sides). That's where you get 14 from. Hoped this helped.

a) Work out the value of 5^2 – 1^5× 2^4
b) Work out the value of 7^2 + 4^3 ÷ 2^5​

Answers

First you have to know BODMAS/BIDMAS (idk if all schools teach it like this) but this is the order in which you complete questions so it’s Brackets, Indices, Division/Multiplication, Addition/Subtraction
a) 5^2 is 5x5 which equals 25 1 to the power of anything is always 1 and 2^4 is 2x2x2x2 which is 16
So 5^2-1^5x2^4 = 25-1x16 which is then 25-16 = 9
b) 7^2+4^3 divided by 2^5 so 7^2 is 7x7 which = 49 then 4^3 means 4x4x4 = 64 and 2^5 is 2x2x2x2x2 which equals 32 so
7^2+4^3 divides by 2^5 is 49+64/32 = 49+2 which is 51
