Answer:
x = -4 y =-4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
10 in
Step-by-step explanation:
Old proportions:
2 x 3
New proportions
h x 15
Assuming the painting has been increased by a constant scale factor.
Where x is the unknown scale factor, and h is the height after it has been enlarged.
Rearrange second equation:
Substitute:
Answer:
y = 3x - 5
Step-by-step explanation:
You use the equation y = mx + b, and you plug in what you know. The slope is already 3 so you do y = 3x + b
after that, you plug in y and x, because (2,1) are the values of x and y.
1 = 3(2) + b
1 = 6 + b
subtract 6 from both sides to isolate the b
-5 = b
Answer:
The number is 3.
Step-by-step explanation:
5x3=15+12=27
9x3=27

Answer:Infinite solutions
Step-by-step explanation:
4(2x+3)=x(3+5)+12
8x + 12= 3x +5x +12
8x + 12 = 8x + 12
No matter the value of x, performing the same operations to both sides will always result in the same answer
