Answer:
m=-3
c=1
Step-by-step explanation:
y=mx+c
m is -3 which is the coefficient of x and c is the intercept 1
Hey there! I'm happy o help!
To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.
-10(-1/3)=3 1/3≠30
30(-1/3)=-10≠-15
-30(-1/3)=10
80(-1/3)=-26 2/3≠-30
Therefore, the correct answer is (-30,10).
Have a wonderful day! :D
Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
The answer would be 54, because A= PQ over 2 = 9 x 12 over 2 = 54
Answer:
Eight more than three times a number subtracted from six times 4
Hope that helps and have a great day!
