\huge{\boxed{y+8=-4(x-2)}}

Point slope form is y-y_1=m(x-x_1), where m is the slope and (x_1, y_1) is any point on the line.

We can simply plug in the values. y-(-8)=-4(x-2)

Then, just simplify the negative subtraction. y+8=-4(x-2)

You have just bought a new television and it has an aspect ratio of 16:9. The screen on the television is 65 inches. What is the
sp2606 [1]

Answer:

A

Step-by-step explanation:

The TV to have a 16:9 ratio and have a diagonal of 65 inches must have a length & width whose squares add to 4,225 (65 squared) and whose ratio length and width simplifies to 16/9.

B is not an option because 16^2+9^2\neq 65^2.

C is not an option because \frac{42.59}{21.22}\neq \frac{16}{9} which is 1.777777777778 as a decimal.

D fails for the same reason as C.

Therefore A is the solution because \frac{56.65}{31.86}=\frac{16}{9} and 65.65^2+31.86^2 = 65^2

Kristin bought eight boxes.A week later half of all her boxes were destroyed in a fire.There are now only 17 boxes left.With how
Dmitriy789 [7]

Answer:

She started with 26 boxes.

Step-by-step explanation:

She started with x boxes. Then she bought 8 more boxes. Now she had x + 8 boxes. Then half the boxes were destroyed, so she has the other half of the boxes. Half of the boxes is (x + 8)/2. She has now 17 boxes, so (x + 8)/2 = 17.

(x + 8)/2 = 17

Multiply both sides by 2.

x + 8 = 34

Subtract 8 from both sides.

x = 26

She started with 26 boxes.
