Answer:
Explanation:
12x = 48 - 8y
10x + 8y = 38
———————
12x + 8y = 48
10x + 8y = 38
———————
12x + 8y = 48
-1(10x + 8y = 38)
————————
12x + 8y = 48
-10x - 8y = -38
————————
2x = 10
x = 10/2 = 5
If x = 5 then:
10x + 8y = 38
10(5) + 8y = 38
50 + 8y = 38
8y = 38 - 50
8y = -12
y = -12/8
y = -3/2
Therefore, x = 5 and y = -3/2
Answer:
Step-by-step explanation:
The area of a triangle is:
A=05*b*h
b= base = x
h = height = x-12
A = (1/2)(x)(x-12)
Answer:
21
Step-by-step explanation:
9c+d
if c= 5
and d=7
9+5= 14+7= 21
I think u are more satisfied now
Answer:
y-3=-3(x+2)
Step-by-step explanation:
Point-slope form is y-y1=m(x-x1).
So if the coordinates given are (-2,3) you substitute the y1 and x1 with those variables, along with determining the slope which is -3/1 because the line goes up towards the left rathar than the right side making it negative.
And there's your equation! Hope that helped.
