Y = .5(x-2) 21
I need help with this problem

x=2

Step-by-step explanation:

Substitute y=0    0=0.5(x-2) 21

multiply the numbers     0=10.5(x-2)        *(21x0.5)

remove the parenthesis     0=10.5x-21

move the variable      -10.5x=-21

divide both sides by   -10.5

solution     x=2

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
