Answer:

The eqaution y + 1 = -2 (x-1) in slope intercept form is

y = -2x - 3

Step-by-step explanation:

Write in slope-intercept form, y = mx + b

Y+1 = -2x+2 (distribute)
Y=-2x + 1 (isolate y)

Rashid [163]

Answer:

1/8

Step-by-step explanation:

1/6 × 3/4

Multiply across top, then bottom

1×3=3

6×4=24

Then reduce if necessary.

3/24

Divide top and bottom by 3

3÷3=1

24÷3=8

You should get 1/8

Answer:

Part 1) The value of x is 50°

Part 2) The measure of angle LOK is 114°

Option C

Step-by-step explanation:

we know that

if two angles are supplementary, then their sum is equal to 180 degrees

(x+64)°+66°=180°

solve for x

x+130°=180°

x=180°-130°=50°

Find the measure of angle LOK

∠LOK=(x+64)°

∠LOK=(50+64)°=114°

Answer:

The least number of questions a student can answer correctly is 32

Step-by-step explanation:

Let

x -----> the number of questions answered correctly

y ----> the total number of questions on a test

$ratio=\frac{x}{y}$

we know that

For a student to earn and A or B on a test, the ratio must be greater than or equal to 0.8

$\frac{x}{y} \geq 0.8$

For y=40 questions

Find the value of x

substitute

$\frac{x}{40} \geq 0.8$

solve for x

Multiply both sides by 40

$x \geq 0.8(40)$

$x \geq 32$

The least number of questions a student can answer correctly is 32

Verify the ratio

For x=32, y=40

$\frac{32}{40}=0.8$

Compare

$0.8 \geq 0.8$ ----> is ok
