Write an expression for each sentence 1. The sum of the square of a number and a second number.

2. Three times the difference of a number and seven.

3. 9.85 less then the product of 37 and a number.

Step-by-step explanation:

1. If x represents a number, then x^2 represents its square. If y represents a second number, then the sum of that square and the second number is ...

  x^2 + y

__

2. The difference of a number (n) and 7 is (n-7). Three times that difference is ...

  3(n - 7)

__

3. If x represents a number, then the product of 37 and a number is 37x. 9.85 less than that is ...

  37x - 9.85

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?
