Answer:
10
Step-by-step explanation:
This equation is in slope-intercept form. Slope-intercept form is
m is the slipe and b in the y intercept if the line. In the equation we are given, 10 is in the place of m, which means 10 is the slioe if the line.
Answer:
Rachel drove on Saturday = 503 miles
Rachel drove on Sunday = 438 miles
Step-by-step explanation:
As given , Rachel drove 65 miles less on Sunday than she did on Saturday.
Let us suppose
Rachel drove on Saturday = x
Rachel drove on Sunday = y
then, we get
y = x - 65
Also given, If twice the miles was driven on Sunday is 373 more than the number of miles driven on Saturday
then , we get
2y = 373 + x
⇒2(x - 65) = 373 + x
⇒2x - 130 = 373 + x
⇒2x - x = 373 + 130
⇒x = 503
∴ we get
Rachel drove on Saturday = x = 503
Rachel drove on Sunday = y = x - 65 = 503 - 65 = 438
Answer: graph №2.
Step-by-step explanation:
Step-by-step explanation: 15 + 13 + 2
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
