Evaluate f(x)=-2×+5 for f(-5)​

Evaluate F(x)=-2+5 For F(-5)

Answers

Answer 1
Answer:

f(-5) = 15 (A)

Step-by-step explanation:

f(x) = - 2x + 5

replace x = - 5

f(-5) = -2(-5) + 5

(-)(-) = +

f(-5) = 10 + 5

f(-5) = 15 (A)

Answer 2

f(-5) = -2(-5) + 5

(-)(-) = +

f(-5) = 10 + 5

f(-5) = 15 (A)

MATCH THE CONSTANT WITH ITS EXPRESSION! HELP PLEASE I SUCK AT MATH❤️❤️❤️❤️

Answers

Answer:

Step-by-step explanation:

The constant of an equation is simply the number at the end without a variable. It is called a constant because it is the only term that doesn't change if you plug in a random x value. So:

The constant of 5a^2 + a - 1 is -1

The constant of 3x^2-x +1 is +1

The constant of y^2-2y+2 is +2

and the constant of m^2 +2m -2 is -2.

the base of a triangle is 4 times the height. if the area is 338 square feet, then what is the height of the triangle in feet

Answers

Area of a triangle = 1/2 * b * h

b = base

h = height

We know:

h = x

b = 4x

Area = 338ft^2

Let's plug these numbers into the Area formula above.

338ft^2 = 1/2 * 4x * x

First, let's divide both sides by 1/2

676ft^2 = 4x * x

Let's simplify the right side.

676ft^2 = 4x^2

Take the sqrt of both sides.

26 = 2x

Divide each side by 2

13 = x

Remember, the height = x = 13 feet

Zach bought 200 shares of Goshen stock 20 years ago for $21.35 per share. He sold all 200
shares today for $43 per share.
a. What was the total purchase price for the 200 shares?

b. What was the total selling price for the 200 shares?

C. What was the capital gain for the 200 shares?

Answers

Answer:

4,330

Step-by-step explanation:

Multiply 21.35 times 200 and you get 4,270, then multiply 200 times 43 and you will get 8,600. then subtract and you will get 4,330

The answers are :

a) The total purchase price for the 200 shares was $4270.

b) The total selling price for the 200 shares was $8600.

c) The capital gain for the 200 shares was $4330.

What is the unitary method ?

The unitary method is a method in which you find the value of one unit and then the value of a required no. of units.

It is given that 20 years ago Zach bought 200 shares.

Price of 1 share = $21.35

a)

The total purchase price for the 200 shares was :

= 200 × $21.35

= $4270

b)

It is given that Zach sold 200 shares today.

Price of 1 share = $43

The total selling price for the 200 shares was :

= 200 × $43

= $8600

c)

The capital gain for the 200 shares was :

= $8600 - $4270

= $4330

Therefore , the answers are :

a) The total purchase price for the 200 shares was $4270.

b) The total selling price for the 200 shares was $8600.

what is 5 divided by 50

Answers

Answer:

50 divided by 5: 10.

5 divided by 50: 0.1

Step-by-step explanation:

Here we will show you step-by-step with detailed explanation how to calculate 50 divided by 5 using long division.

Before you continue, note that in the problem 50 divided by 5, the numbers are defined as follows:

50 = dividend

5 = divisor

Step 1:

Start by setting it up with the divisor 5 on the left side and the dividend 50 on the right side.

Step 2:

The divisor (5) goes into the first digit of the dividend (5), 1 time(s). Therefore, put 1 on top.

Step 3:

Multiply the divisor by the result in the previous step (5 x 1 = 5) and write that answer below the dividend.

Step 4:

Subtract the result in the previous step from the first digit of the dividend (5 - 5 = 0) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (0)

Step 6:

The divisor (5) goes into the bottom number (0), 0 time(s). Therefore, put 0 on top.

Step 7:

Multiply the divisor by the result in the previous step (5 x 0 = 0) and write that answer at the bottom.

Step 8:

Subtract the result in the previous step from the number written above it. (0 - 0 = 0) and write the answer at the bottom.

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 50 divided by 5 OR 5 divided by 50 calculated using Long Division is:

50 divided by 5: 10.5 divided by 50: 0.1

Answer:

72.25

Step-by-step explanation:

Lets say you are trying to find p percent (p%) of a number n. To do this, you would divide the percent (p) by 100 and multiply it by the number (n). In other words:

[tex]n*\frac{p}{100}[/tex]

We can use this to find 17 percent of 425. 17 would be our percent and 425 would be our number.

[tex]425*\frac{17}{100}=425*0.17=72.25[/tex]

So 17 percent of 425 would be 72.25.

What is the value of x? Enter your answer in the box. x = cm A bow tie shape polygon made of two bow ties that share a vertex. The shape is created by two segments intersecting forming two triangles with vertical angles. An alternate interior angle of the triangles are marked congruent to each other. The larger triangle is on the left and the smaller triangle is on the right. In the larger triangle, the left side of the triangle is 32 centimeters. The south side of the triangle is 40 centimeters. On the smaller triangle, the right side of the triangle is 4 centimeters. The north side of the triangle is labeled x.

Answers

Answer:

side x is 5 cm long

Step-by-step explanation:

Use proportions, given that the two triangles are similar because they contain three equal angles:

One angle due to connected by the vertex (oppose by the vertex), another angle as marked with the tick, and the third one has to be the same due to the fact that the addition of the three internal angles of a triangle must equal 180 degrees.

Then our proportion becomes:

[tex]\frac{4}{32} =\frac{x}{40}[/tex]

And then we solve for x by multiplying both sides by 40 (to eliminate the denominator on the right):

[tex]\frac{4}{32} =\frac{x}{40} \\\frac{4*40}{32} =x\\ x=5\,\,cm[/tex]
