The third one (I think) because she gets 20$ every week
I think B similar but you can use quizzing to find the answer that always gives you answers to the WHOLE quizz
2x + 3y = 12 (1st)
5x − y = 13 (2nd) ---> y = 5x - 13
Substitute y = 5x - 13 into (1st) equation
2x + 3(5x - 13) = 12
2x + 15x - 39 = 12
17x - 39 = 12
17x = 51
x = 3
substitute x = 7 into y = 5x - 13
y = 5x - 13
y = 5(3) - 13
y = 15 - 13
y = 2
Answer
solution x = 3 and y = 2
Answer: Personality testing refers to techniques that are used to accurately and consistently measure personality.
Step-by-step explanation: Personality is something that we informally assess and describe every day. When we talk about ourselves and others, we frequently refer to different characteristics of an individual's personality.
Answer:
y = x + 4
Step-by-step explanation:
Well, the important thing is to get the slope first. The slope here is 1.
Here's how to find the slope yourself:
m (slope) = (y₁ - y₂)/x₁ - x₂
m (slope) = (3 - 4)/(-1 - 0)
m (slope) = -1/-1
m (slope) = 1
So, we found the slope. Now, plug it into the equation. y = 1x + b. Cool, so now let's choose the first point to solve this.
So, 3 = 1(-1) + b
3 = -1 + b
3+1 = -1+1 + b
The ones cancel out...
4 = b
So, now you plug that into the equation... y = 1x + 4, although you would write it as y = x + 4.
