Write an equation of the line shown. Then use the equation to find the value of x when y=70.

Answers

Answer 1

Answer:

Answer:

x = 9

Step-by-step explanation:

The slope would be 6

Y -int would be 16

Through this we can find out that the slope-intercept form is

y = 6x + 16

insert 70 into y

solve for x

70 = 6x + 16

54 = 6x

9 = x

Answer 2

Answer:

The equation of the line is y = 4x + 18 and the value of x is 13

How to determine the equation of the line

From the question, we have the following parameters that can be used in our computation:

The graph

A linear equation is represented as

y = mx + c

Using the points, we have

m + c = 22

4m + c = 40

When evaluated, we have

3m = 12

m = 4

So, we have

4 + c = 22

c = 18

Next, we have

y = 4x + 18

When y = 70, we have

4x + 18 = 70

Evaluate

x = 13

Hence, the value of x is 13

Please Answer ASAP Math Question

Given that j || k, what is the measure of the missing angle?A) 30°
B) 40°
C) 60°
D) 120°

Answers

Answer:

the measure of the missing angle is 60°

Step-by-step explanation:

GIVEN : j || k

solution :

We will use the property of linear pairs

120° + ∠1 = 180° (sum of linear pairs is 180°)

⇒ ∠1 = 180°- 120°

⇒∠1 = 60°

now since j || k

So, we can use corresponding angle properties

So, ∠? = ∠1 (corresponding angles are equal)

⇒∠? = ∠1 = 60°

Thus ? = 60°

60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.

chad poured a sidewalk that is 42 ft long. He is going to start at the beginning and make a cut every 20 inches. How many cuts will Chad make?

Answers

So The First Step in tackling this problem is first do $42x12$ , The reason why we do this is because we are converting feet to inches. After that we will get 504 inches. The next and final step is to do 504÷20. Then we will get 25.2 so the final answer is that Chad will make 25 cuts.

Twice because you would divide the 2 numbers together, and you get a small decimal. But since you can't cut a decimal then It would be 2, so 2 cuts. :)

From the question, we are told that 2 1/2 feet is 5/8 of the height of the tower to be built

Now, we want to get the equation for the height of the tower

we have this as follows;

since we do not know the height of the tower, we can represent it by ?

a. 5/8 of ? = 2 1/2

b. 2 1/2 divided by ? = 5/8

c. 2 1/2 • 8/5 = ?

d. 2 1/2 divided by 5/8 = ?
