If I’m correct I believe the answer is gonna be B
To find the intersecting point, you have to put the two formulas equal to each other
First isolate the same variable, in this case y
So y=x-4
Now we can say
2x + 7 = x - 4
Now solve for x
X= 3
Now fill this in in either one of the formulas
Y= 2 (3) + 7
Y= 13
So they’ll intersect at (3,13)
Answer: x = 6
Step-by-step explanation:
9(8 - x) = 3x
72 -9x = 3x
add 9x to both sides
72 = 12x
divide 72 by 12
x = 6
Answer:
volume = 79.6
mass = 1126.3g
Step-by-step explanation:
Answer: 194
Step-by-step explanation:
1. Square both sides to get (b+2)=14^2=196
2. Subtract 2 from both sides to get b=194
