Answer:
4
Step-by-step explanation:
We'll begin by calculating the slope of the equation. This is illustrated below:
y = 4/3x + 1
Comparing the above equation with:
y = mx + c
The slope (m) of line is 4/3.
Next, we shall determine the slope of the equation perpendicular to:
y = 4/3x + 1
This is illustrated below:
When two lines are perpendicular, their slope are related as:
m2 = – 1/m1
From the above, m1 = 4/3
m2 = –1 ÷ 4/3
m2 = –1 × 3/4
m2 = – 3/4
Next, we shall determine the equation passing through (4, 1). This is illustrated below:
y – y1 = m(x – x1)
y1 = 1
x1 = 4
m = – 3/4
y – y1 = m(x – x1)
y – 1 = –3/4 (x – 4)
y – 1 = –3/4x + 3
y = –3/4x + 3 + 1
y = –3/4x + 4
Comparing:
y = –3/4x + 4 with y = mx + c
The y-intercept, c is 4.
Line Q, you always want the line that has as many dots on it as possible!! :)
75% of the repair bill is 53.25
0.75x = 53.25
x = 53.25 / 0.75
x = 71 <== total cost of the bill
Hi there! So, the price is up by 110%. That would mean doubling the price, but that’s not an option. Instead, we can multiply by 110% (1.1) to find the new price of the juice. 2.85 * 1.1 is 3.135 or 3.14 when rounded to the nearest hundredth. The new price of the juice is $3.14. The answer is D.
