Answer:
A.
Step-by-step explanation:
Sub in the (x,y) points given into the equation to see if true ....you'll find A is the answer
Example point (3,95 ) 95 = -10.375 (3) + 126.125 ??
95 = 95 Check !
then try the other point ( 11,12) to be sure ....
The three answers you have are correct. The last fourth answer is coincidentally "angle 4". If another number other than '4' was in the diagram, then you would label it as angle X (replace X with that number in question).
note: you can say "angle 4" or you can use the angle markers as you have been doing. It's probably best to stay consistent.
Answer:
nuber 1
Simplifying
3x + 2y = 35
Solving
3x + 2y = 35
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 35 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 35 + -2y
3x = 35 + -2y
Divide each side by '3'.
x = 11.66666667 + -0.6666666667y
Simplifying
x = 11.66666667 + -0.6666666667y
Answer:
The Answer is 20
Step-by-step explanation:
let's take wife's age as x
given,
(40 + x)/2 = 30
40 + x = 30*2
x = 60 - 40
x = 20
