Answer:
Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. –4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 – 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.
Step-by-step explanation:
The solution of the Equation 9 = q – 4 is 13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
9 = q – 4
We have to use the inverse operation as
Addition inverse Subtraction and vice versa.
Division inverse Multiplication and vice versa.
So, 9 = q – 4
Undo the subtraction of 4 by adding 4 to both sides of the equation.
9 + 4 = q- 4 +4
13 = q
Hence, the solution is 13.

Step 1: Define
y = home runs
x = hits
[Best Line of Fit] y = 0.15x - 1.5
We can use this to predict the average of the scatter plot.
home runs = y = 30
Step 2: Solve for x hits
Substitute [BLF]: 30 = 0.15x - 1.5Add 1.5 to both sides: 31.5 = 0.15xDivide 0.15 on both sides: 210 = xRewrite: x = 210Remember that this is a prediction. According to the best line of fit, we would need 210 hits to get 30 home runs.

Answer:
t = -14
Step-by-step explanation:×
I did 4+3 which equals 7.
Now I know I need t/-2 to equal 7.
Next, I did 7×2 which equals 14.
When you divide 2 negative numbers you get a positive number.
So -14 ÷ -2 = 7
So t = -14
