Answer:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.

Step-by-step explanation:

Given the equation

y = -2x+ 5

<u>Checking the ordered pair (2, -9)</u>

substituting x = 2 and y = -9 in the equation

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1

FALSE!

L.H.S ≠ R.H.S

Thus, the ordered pair (2, -9) is NOT a solution of the equation.

<u>Checking the ordered pair (-2, 9)</u>

substituting x = -2 and y = 9 in the equation

y = -2x + 5

9 = -2(-2) + 5

9 = 4 + 5

9 = 9

TRUE!

L.H.S = R.H.S

Thus, the ordered pair (-2, 9) is a solution of the equation.

Conclusion:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.

lozanna [386]

Answer:

A. the times at which the golf ball is on the ground

Step-by-step explanation:

The expression of the function is

h(x)= -4x^2+36x

The roots can be seen in the image below

You have a formula which represents the height over time.

The roots of the equation indicate that the height is equal to zero

The correct option is

A. the times at which the golf ball is on the ground

The ball is in the ground at x= 0 and x = 9 seconds

Can someone show me how to do this?

kupik [55]

Y=mx+b is equation form.

Step 1: Calculate slope

Slope= y2-y1/x2-x1
Choose 2 points (8,7) and (0,1)
Apply slope formula: 1-7/0-8=-6/-8=3/4(simplified)
M=Slope
Y=3/4x+B
B=Y intercept: 1

Equation: Y=3/4x+1

(I can give a more thorough explanation if you have any questions).
