Answer:

<em>624 is the answer</em>

Step-by-step explanation:

5x²-3x+5        x=2

plug in x=2: 25²-6+5=?

do the 25²: (25*25=625)

plug in 625 into the equation: 625-6+5

subtract 6 from 625: 625- 6= 619

plug 619 into your equation: 619+5=?

add 5 to 619: 619+5= 624

Step-by-step explanation:

5x² – 3x + 5

Substitute 2 in for x

5(2)² - 3(2) + 5

Solve exponents first

5(4) - 3(2) + 5

Solve/multiply parenthesis

20 - 6 + 5

Add and subtract

Which point is an x-intercept of the quadratic equation (x-8)(x+9)
defon

Solve for x in each set of parentheses by setting them to 0:

X -8 = 0

X = 8

X+9 = 0

X =-9

You have two x intercepts (8,0) and (-9,0)

You didn’t list any choices to pick from but it would be either if the ones above.
