andre [41]3 years ago
6 0

Answer:

9

Step-by-step explanation:

If PQ || to BC

Then by BASIC PROPORTIONALITY THEOREM:

\frac{8}{40}  =  \frac{x}{45}  \\  \\  \frac{1}{5}  =  \frac{x}{45}  \\  \\ x =  \frac{45}{5}  \\  \\ x = 9

Line m passes through the points (-2,7) and (4,-5), as shown below. Which of the following could be the equation of a line that
True [87]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be parallel, they need to have the same slope.

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}      And plug in the two points

(-2, 7) = (x₁, y₁)

(4, -5) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-5-7}{4-(-2)}   (two negative signs cancel each other out and become positive)

m=\frac{-5-7}{4+2}

m=\frac{-12}{6}     Simplify the fraction

m = -2        

The slope is -2, so the parallel line's slope is also -2.

Your answer is C

Kayleigh wants to buy a car that costs $13,080.00. She deposits $12,000.00 into a savings account that earns 3% simple interest.
Ipatiy [6.2K]
The formula is
A=p (1+rt)
A cost of the car 13080
P amount deposited 12000
R interest rate 0.03
T time?
Solve for t
T=[(A/p)-1]÷r
T=((13,080÷12,000)−1)÷0.03
T=3 years

I need help fast please...
BARSIC [14]

Answer:

87: y = 5

88: y = 0

89: y = -2

90: y = -1/2x + 9

91: y = 2x - 16

92: y = x - 11


Step-by-step explanation:

To find the slope(m): (y1 - y2)/(x1 - x2)

To find the y-intercept:

y = mx + b

Replace m with the slope and x and y with one of the sets of coordinates. Then simplify to get the y-intercept. Use the equation y = mx + b and replace m with the slope and b with the y-intercept to get the equation.


(Sorry if this is a little confusing.)
