Can someone me on this problem? i don’t understand

  A = -9, B = 65

Step-by-step explanation:

Take the square root of both sides of the equation:

  h + 9 = ±√65

Subtract 9 from both sides of the equation:

  h = -9 ± √65

Comparing this to the form

  h = A ± √B

we see that A = -9 and B = 65.

A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.

It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.

The stuff under the radical is the value of B. That stuff is 65.

answer: c i think

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
