The equation looked for is this:
y = zx^2
we need to find the z value, and we can do that by substituting the data provided in the problem, lets substitute data:
<span>y = zx^2
</span>196 = z(7)^2
196 = 49z
z = 196/49
z = 4
therefore the equation is:
y = 4x^2

Laura spent 78.5% of her paycheck on her mortgage payment. If her paycheck was $1562 how much was her mortgage?
torisob [31]

Answer:

$337.12

Step-by-step explanation:

Multiply $1562 by 78.5% (or 0.785) =1230.88

Then subtract the percent of her paycheck spent (1230.88) from the total of her paycheck(1562) to find out how much is missing(the mortgage payment)

1562-1230.88=337.12

How can u covert 10x-7y=-8 to a slope intercept form?
PtichkaEL [24]
Slope intercept form:  y = mx + b
                                 
-7y = -10x - 8 
    y = 10/7x - 8

hope this helps :)
