Here what you need to do is plug in each x value and solve for y
I would rewrite the function to make it easier
-10x+y=4
y=10x+4

Then plug in each x
y=10*-2+4
y=-20+4
y=-16
(-2, -16)

y=10*-1+4
y=-10+4
y=-6
(-1, -6)

y=10*0+4
y=4
(0,4)

y=10*1+4
y=10+4
y=14
(1, 14)

y=10*2+4
y=20+4
y=24
(2, 24)

Answer:

C. It would be shifted up.

Step-by-step explanation:

We base it off the y-intercept. Since -7 is less than 1, and our new function has a positive y-intercept, it would indeed be shifted up.

If point C is between points A and B, then AC + CB = ___.

mario62 [17]

The correct answer is: AB

Explanation:

There are two ways you can understand this:

1. By drawing:

A ------ C ------B

As you can see the point C is between A and point B, hence AC + CB = AB. One thing to remember here is that point C can be anywhere between the point A and B, in that case, the answer will remain be the same AB. For instance:

A --- C -------------B

Again, AC + CB = AB.

2. By inference:

If the point C is between points A and B, it means that the point C lies on the line AB; if point C were not on the line AB, it will not be between points A and B. Hence, you can infer that AB is a line and point C lies on it and is between points A and B.

Can anyone solve it plzzzz

Vedmedyk [2.9K]

Answer:

1.A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

Solution given:

We have

Sin² $\theta$ -Cos ² $\theta$ =1

Sin² $\theta$ =1+Cos² $\theta$

Sin $\theta$ = $\sqrt{1-Cos²\theta}$

4Tan² $\theta$ +4Cot² $\theta$ -3Tan² $\theta$ -3Cot² $\theta$

4Tan² $\theta$ -3Tan² $\theta$ +4Cot² $\theta$ -3Cot² $\theta$

Tan² $\theta$ -Cot² $\theta$

A triangle has an angle that measures 90°. The other two angles are in a ratio of 2:7. What are the measures of those two angles

marin [14]

Answer:

70° and 20°

let the other 2 angles be 7x and 2x

90+7x+2x=180

9x=180-90

x=90/9

x=10

7x=7x10

2x=2×10
