Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .<span>X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 30/5 = 6.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 30/-3 = -10.Slope is -5/-3 = 1.66666666666667.<span> Equation in slope-intercept form: y=1.66666666666667*x+-10.</span></span>
Answer:
32
Step-by-step explanation:
let a = 5
a² + 7 | Original equation
5² + 7 | Substitution of a as 5
25 + 7 | 5 to the power of 2 is 25, as 5*5 = 25.
32 | 25 + 7 = 32
