Answer:
B. y = 2x + 5
Step-by-step explanation:
Slope intercept formula y=mx+b
Slope formula y1-y2/x1-x2
First, let's find slope since we are provided 2 pairs of points, we can simply plug in our numbers in the Slope formula (y1-y2/x1-x2)
5-7/0-1
-2/-1
2/1
=2
Slope (m) = 2
Now using slope let's find our y-intercept (b) to plugin in our slope intercept formula (y=mx+b) for this let's use point 0,5
y=2x+b
5=2(0)+b
5=b
Y-intercept (b) = 5
Now let's plug in the slope (m) and the y-intercept (b) into the slope-intercept formula (y=mx+b)
y=mx+b
y=2x+5
So therefore our answer is B
Answer:
$2.16
Step-by-step explanation:
7.56 ÷ 7 = 1.08
1.08 × 2 = 2.16
Put one number as x and the other as y
x+y=83
Since we already know one is 45, we substitute one of them for 45.
45+x=83
Subtract 45 on each side
x=38
The other number is 38. Hope this helps.
Answer:
200
Step-by-step explanation:
So its basically you multiply the length by the width which is 15 times 5 which is 75 then you multiply 75 times 4 which is 200 so the answer is 200.
