Answer:
x=
Step-by-step explanation:
y=7x-2
2(7x-2)-4x=10
14x-4-4x=10
14x-4x=10-4
10x=14
x=
Answer:
3.C
Step-by-step explanation:
the line is going down so the slope is negative and the y intercept is 4. also to find the slope fine a point for example 1,1 so either go up or down the the next point like 0,4 so it up 3 and over one which is 3/1 which is just 3.
4.c
for the slope you go up 5 over 1 for and for the y intercept will always gave 0 and something beside it but sense it us 0 then you just done have one also you can just plot the points and make a line as well.
R=rockhopper penguin, emperor=45
r=45-24=21 inches tall.
The answer is reasonable, because if an emperor penguin is 45 inches tall. You subt. 45-21=24 inches taller than the rockhopper penguin.
(x+10)(x-3). I’m assuming you meant x^2
