Answer:

7. y=x-2, 8. y=3/2x+4, 9.  y=-3/4x+8, 10. y=2x-7, 11. y=-5x-3, 12. y=4x-5,             13. y=-3x-1, 14. y=-1/2x+1, 15. y=3/2x+4

Step-by-step explanation:

First you have to plug in the points into y2-y1/x2-x1. This would make it      -2-0/0+1. Simplify this to get -2/1 which is -2. This makes the slope -2. Then plug in the slope into point intercept form y-y1=m(x-x1) where m is the slope. This time, I will use the point (0,-2). Therefore, the equation will be y+2=1(x-0) which is equal to y+2 =x-0 which is equal to y=x-2.

This is how you do all of the problems. For problem 13-15, you know that f(0)=-1 is (0,-1) and f(3)=-10 is (3,-10). Then you can solve the problems. I will not explain every single problem but will give you the answers.

Answer:

The two supplementary angles are 10 and 170 degrees.

Step-by-step explanation:

Two angles are supplementary when that add up to 180 degrees. In this case, we are given that one of the two angles is 160 degrees more than the other. We can construct the following equation. x + ( x + 160 ) = 180 x

represents the degree measure of the smaller angle. Now, all we need to do is solve the equation for x. 2 x + 160 = 180    2 x = 20 x = 10

Now that we have the value of the smaller angle, we can easily solve for the larger angle. We are told that it is 160 degrees larger than the other one.

10 + 160 = 170. Therefore, the two supplementary angles are 10 and 170 degrees.

Answer:

150

Step-by-step explanation:

The required percent error by Samantha is 50%, as of the given condition,

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Errors are discrepancies between values that are seen and natural truths.

Here,
Samantha guessed there were 375 jelly beans.
The actual amount of jelly beans in the jar was 250.
Error percentage = 375-250 / 250 × 100
                           = 0.5 × 100
                           = 50%

Thus, the required percent error by Samantha is 50%, as of the given condition.

Answer:

If Step is 53 = 477 then no solution exist

If Step is 53 x = 477 then there exist a unique solution x = 9

Step-by-step explanation:

Given - Ramon solves a linear equation. One of the steps in his work is

             53 = 477

To find - Which of these describes the solution to the equation that Ramon

              solves?

Proof -

As given, One of the steps in his work is 53 = 477

There are 2 cases possible -

Case I:

If his step is 53 = 477

Then, the equation has no solution because 53 ≠ 477

Case I:

If his step is 53 x = 477

Then, the equation has a solution because x = [tex]\frac{477}{53}[/tex] = 9

⇒The equation has a solution of x = 9.

Answer: 2.18

Step-by-step explanation:

Angle B= 180- (Angle A + Angle C)

= 180- (70+90)

= 180-160=20

((sin A)/BC)=((sin B)/AC)

((sin 70)/6)=((sin 20)/AC)

(0.9/6)=(0.3/AC)

AC= (6*0.3)/0.9

AC= 2.18

Step-by-step explanation:

Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

The given expression can be written as,

2⁶ = 2 × 2 × 2 × 2 × 2 × 2

   = 4 × 16

   = 8 × 8

Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.
