What Is The Equation Of The Trend Line In The Scatter Plot?Use The Two Yellow Points To Write The Equation

Answers

Answer 1

Answer:

y = 7/5x - 21/5

Step-by-step explanation:

points to use to find slope:  (3,0) and (8,7)

slope = 7-0 / 8-3

slope = 7/5

find y-intercept (or 'b')

0 = 3(7/5) + b

0 = 21/5 + b

-21/5 = b

b = -4 1/5

WHAT IS THE PERIMETER OF THE TRIANGLE

GET THIS RIGHT AND YOU GET 100 POINTS

Answers

Answer:

40

Step-by-step explanation:

SO im guessing if its the full graph one box counts 1.

So the top side counts 8

The left one is 15

The perimeter means adding all the sides together.

We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.

a^2+b^2=c^2

8^2+15^2 = c^2

64+225 = c^2

289 = c^2

c = 17

so the perimeter is 8+15+17 = 40

What is the equation of an exponential function with base=2 that has a vertical stretch by a factor of 3, a shift to the right 5 and a shift up 6 ?

Answers

Answer:

[tex]y=3(2)^{x-5}+6[/tex]

Step-by-step explanation:

Let the equation of the exponential function with base 2 is,

[tex]y=a(2)^{x+c}+d[/tex]

Here, a = vertical stretch

c = Horizontal shift

d = Vertical shift

If this function has a vertical stretch by a factor of 3,

Equation will be,

[tex]y=3(2)^{x+c}+d[/tex]

If this function has a shift of 5 to the right,

Equation of the function will be,

[tex]y=3(2)^{x-5}+d[/tex]

If this function has a shift of 6 units upwards,

[tex]y=3(2)^{x-5}+6[/tex]

Solve. 2(2z + 5) = 50​

Answers

Answer:

z = 10

Step-by-step explanation:

Distribute 2 to the terms in the parentheses:

2(2z + 5) = 50​

4z + 10 = 50

Subtract 10 from both sides

4z = 40

Divide each side by 4

z = 10

So, the answer is z = 10

Answer:

10

Step-by-step explanation:

1. Factorize left side.

2*2z+2*5=50

4z+10=50

2. Subtract 10 from both sides

4z=50-10

4z=40

3. Divide both sides by 4

z=40/4

z=10

Step-by-step explanation:

7A. I forget what the rule is called specifically, but the opposite angle is always congruent. So, you simply end up solving for x when you set the equation to equal 45.

7B. Use the supplementary rule, which basically states that two angles on a flat plane, when adjacent, equal 180°. So, 180 - 45 = 135.
