Answer:
B. r=7.5
yan po ang correct answer
Answer:
16
Step-by-step explanation:
Add 13 both sides
That would give you 5v=80
Divide 80 by 5. So v would equal 16
Okay so here's the definition of quantitative just in case you ever need it :) Categorical. Categorical variables take on values that are names or labels. The color of a ball (e.g., red, green, blue) or the breed of a dog (e.g., collie, shepherd, terrier) would be examples of categorical variables. And the answer would be A the color of your car because it talks about in the definition of the color of a ball so A would be the correct answer! Please mark brainliest :)
Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
Answer:
x = -12
Step-by-step explanation:
4/3x + 12 = - 4 (multiply 3 both side)
4x + 36 = - 12 (minus 36 both side)
4x + 0 = -12
4x = -12 - 36
4x = - 48 (divide both side)
4x ÷ 4 = x
-48 ÷ 4 = -12
Answer: x = -12
