If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6
Let the unknown number be x
The square of the number is expressed as x²
Triple of the unknown number will also be expressed as 3x
Taking the sum of both numbers and equating it to 18 will give;

Factorize the resulting equation:

Hence the required numbers are 3 and -6

Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)

Slope = (-2)
38) (7 , 0) & (3 , 2)

39) The line is parallel to x-axis and so its slope is 0
Slope = 0
40) The line is parallel to y-axis and so its slope is undefined
Slope = undefined
(-2,7) and (14,21)
Find the slope by using the formula

Plug in the numbers.

Write it in point slope form first
y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
+ 7 +7
y = 7/8x + 8.75
Our final equation would be: <span>
y = 7/8x + 8.75</span>
