Answer: 30
Step-by-step explanation:
Example
x=y
x+z=y+z
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
x=y
x−z=y−z
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
x=y
x÷z=y÷z
If we multiply both sides of an equation by the same number, both sides will remain equal.
x=y
x⋅z=y⋅z

Solve the following expression
4x−7=x3+4
Answer:
1) 8
2) -2
3) 6
Step-by-step explanation:
1) First, find the pattern in the table, with X the pattern is +1, but with Y the pattern is +2. So to find the Y-intercept in the table you need to subtract 1 from X and subtract 2 from Y. The answer is 8.
2) On a graph it is really easy, it is where the line touches the Y-axis, in this case, it is -2. The answer is -2.
3) With the equation y=mx+b, the M is the rise/run and the B is the Y-intercept, and the B in the equation is 6. The answer is 6.
Answer:
x=20
Step-by-step explanation:
y=90
70+90=160
180-160=20
90+70+20=180
21 is the answer for this problem
