Answer:

a = 0 ; a = -10

Step-by-step explanation:

a squared number give as result a positive number, either if it is positive or negative

we have to find two numbers whose square is 25: these numbers are 5 and -5

a+5 = 5

a = 0

a+5 = -5

a = -10

Answer:

(a+5)^2=25 means a^2+5^2=25, a^2=25-25 then a^2=√0, a=0

What is the equation, in slope-intercept form, of the line that is perpendicular to the line

wolverine [178]

Answer:

y=3/2x+1

Step-by-step explanation:

y-4= -⅔(x-6)

y-4=-⅔x+4

y=-⅔x+4+4

(equation of line 1) y= -⅔x+8 gradient= -⅔

(line 2)gradient=3/2

note* the gradients of perpendicular lines multiplied result to -1

gradient=y²-y²

x²-x¹

3 =y+2

2. x+2

multiply both sides by 2(x+2)to remove the denominators

3(x+2)=2(y+2)

3x+6=2y+4

3x+6-4=2y

3x+2=2y

divide all sides by 2

3/2x+1=y

y=3/2x+1
