Answer:
x = 3 - 3/2y
y = 2 - 2/3x
Step-by-step explanation:
2x + 3y = 6
2x = 6 - 3y
x = 3 - 3/2y
2x + 3y = 6
3y = 6 - 2x
y = 2 - 2/3x
.23(m)-12=35.
Think this is right. Haven't done these in a while
First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665
Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.
