Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11
Answer:
3.7
Step-by-step explanation:
Hope this helps
Answer:
y-6=3/2(x+8)
Step-by-step explanation:
so the point slope form is y-y₁=m(x-x₁)
so enter the points (-8, 6)
y-6= 3/2(x-(-8))
y-6=3/2(x+8)
You can get E real quick
how? you know that D is 90 and f is given 66 and you know that D+E+F=180 so E=180-(90+66) which gives us 24
