What is the slope of the line?<br><br> A: 3<br><br> B: - 3<br><br> C: - 1<br><br> D: 1
Shtirlitz [24]

Answer:

A

Step-by-step explanation:

To find the slope of a line, we can use the slope formula:

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

So, we will need to choose two points from the graph. Any two points will work.

Let’s choose (0, -1) and (1, 2).

So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:

\displaystyle m=\frac{2-(-1)}{1-0}

Evaluate:

\displaystyle m=\frac{3}{1}=3

Therefore, the slope of the line is 3.

Hence, our answer is A.

A right triangle is displayed.
Mazyrski [523]

Answer:

You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6
vodka [1.7K]

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial -3x^4+2x^3-x^2+6 through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial -3x^4+2x^3-x^2+6 .

(x+1)(-3x^3)=-3x^4-3x^3

We subtract this from the original -3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6.

This leaves 5x^3-x^2+6. We repeat the step above.

(x+1)(5x^2)=5x^3+5x^2.

We subtract this from 5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6. We repeat the step above.

(x+1)(-6x)=-6x^2-6x.

We subtract this from -6x^2-(-6x^2)+0x-(-6x)+6=6x+6. We repeat the step above.

(x+1)(6)=-6x+1.

We subtract this from 6x-(6x)+6-(6)=0. There is no remainder. This means (x+1) is a factor.

Answer the other following question.
pychu [463]

Given:

L = W - 4

P = 2L + 2W

We can substitute 2L for 2(W - 4) = 2W - 8

So:

2W - 8 + 2W = P

P = 4W - 8

Answer is 4. 4W-8

Ms. LaTrace teaches her 27 students to make folded-paper princesses. Each student can make about 2 princesses in 1 minute. ABOUT
saveliy_v [14]

Answer:

About 2970 princesses

Step-by-step explanation:

This is calculated as:

For 1 student:

1 minute = 2 princesses

55 minutes = x princesses

x = 55 × 2 princesses

x = 110 princesses.

Hence: 1 student can make 110 princesses in 55 minutes.

The amount of princesses all the students make in 55 minutes is calculated as:

1 student = 110 princesses

27 students = x

x = 27 × 110 princesses

x = 2970 princesses

The amount of princesses all the students make in 55 minutes is about 2970 princesses.
