Answer:
C. Bentley got $20 for her allowance.
Step-by-step explanation:
If Bentley was given $40 at first, then spent $10, we plot a line on the graph that decreases and then she receives $20. $20 is bigger than $10, therefore this is the scenario best represented by a linear increasing interval.
I hope this makes sense!! ^-^
Answer:
y= 4x+3
Step-by-step explanation:
To write your equation, solve for the slope.
(y2-y1)/ (x2-x1)
Find two coordinate points from the table.
(0,3) (1,7)
(7-3)/ (1-0)= 4
m=4
Use point-slope equation to find your equation.
(y-y1)=m(x-x1)
(y-3)=4(x-0)
y-3= 4x
y= 4x+3
It has to be the last one, D. I did it over 3 times to make sure.
Answer:
X = - 3
Step-by-step explanation:
Let x+y=10 be equation (1)
and y=x-4 be equation (2)
from (2)
y=x-4...(3)
sub (3) into (1)
x+(x-4)=10
x+x-4=10
2x=12
x=6
sub (x) into (3)
y=6-4
y=2
