Evaluate the expression if y = -4. | 2/y + 1/2 (y+6)

DO NOT SEND ANY LINKS.

Answers

Answer 1

Answer: look at the picture

Step-by-step explanation: Hope this help :D

Answer 2

Answer:

0.5

Step-by-step explanation:

If y = -4, then we must replace every variable y with the number 4. So, let's do that.

2/-4 + 1/2*(-4 + 6)

All we have to do now, is simplify. Parenthesis first...

2/-4 + 1/2*2

We can replace the 1/2*2 with 2/2 because they are the same thing.

2/-4 + 2/2

Now, solve from left to right.

-0.5 + 1 = 0.5

Therefore, the answer is equal to 0.5. Hope this helps!

solving steps for 2/3(9+x) = -5(4-x)

Answers

Answer:

x = -6

Step-by-step explanation:

2/3(9+x) = -5(4-x) ( 2/3times9=6, 2/3timesx=2/3x) ( -5times4=-20,-5timesx=-5x)

6 + 2/3x = -20 -5x ( add 20 on both sides)

26 + 2/3x = -5x ( minus 2/3x on both sides)

26 = -4.6x (divided -4.6x on both sides)

-5.6 = x ( round up)

-6 = x

The figure below consists of a triangle, a rectangle, and a trapezoid.
What is the area of the figure in square units?
A. 39
B. 37
C. 49
D. 42

Answers

Answer:

Area of the figure = 39 square units

Step-by-step explanation:

Find the diagram attached

Area of the triangle = 1/2 * base * height

Base of triangle = 4

Height = 1 + 5 = 6

Area of the triangle = 1/2 *4 * 6

Area of the triangle = 12units²

Area of rectangle = Length * Width

Length = 4

Width = 5

Area of rectangle = 4 * 5

Area of rectangle = 20units²

Area of trapezoid = 1/2(a+b)*h

a and b are the parallel sides

h is the height

a = 2

b = 5

h = 6-4 = 2

Area of trapezoid = 1/2(2+5)*2

Area of trapezoid = 1/2*7*2

Area of trapezoid = 7units²

Area of the figure = Area of the triangle +Area of the rectangle + Area of the trapezoid

Area of the figure = 12 + 20 + 7

Area of the figure = 39 square units

question number 2
what volume of oats will fill the container? Round your answer to the nearest tenth.

Answers

9514 1404 393

Answer:

145.3 square inches

Step-by-step explanation:

The lateral area of the cylinder is given by ...

LA = 2πrh

LA = 2π(2.5 in)(9.25 in) = 46.25π in²

LA ≈ 145.3 in²

About 145.3 square inches of paper is used for the label.

The regular polygon has radii and an apothem as shown. Find the measure of each numbered angle.

Answers

9514 1404 393

Answer:

∠5 = 60°

∠6 = 30°

∠7 = 120°

Step-by-step explanation:

Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)

∠5 = 60°

∠6 = 30°

∠7 = 120°

The answer is b, there is only 1 y intercept so b is not true

Answer:

Step-by-step explanation:

So for answer choice 1, we can confirm it is correct because if we check there are 2 x intercepts (when it hits x-intercept). For answer choice 2, we only see 1 y intercept ( when it hits y-axis). So that can't be right. We'll keep moving and we can see the the maximum (highest point on the graph) truly is (1,2) so that is correct, and the axis of symmetry (if you would fold the graph in half, the point on the x-axis where it would fold) indeed is 1, so we can confirm the answer is B. Hope this helps!

Answers

Answer:

Many people rush into relationships, whether it be romantic or friendly. No matter the kind of relationship, the number one thing you want to make sure you have is boundaries. When you get to know someone, you have to make sure they respect your beliefs, your boundaries, and won't peer pressure you into doing anything. You also want to make sure the person you are getting to know is getting to know you for you and not anything else. It has been proven that the more happy relationships and healthy relationships we have, the longer we live. But it also works the other way around. That's why we have to make sure we surround ourselves with the right kinds of people otherwise, we'll just end up getting hurt. It's very common for people to be influenced by outside forces and, therefore, hurt us and turn around and instead of being our loved ones, they're our enemies. That's why we have to make sure we choose the right kinds of people.

By drying out (removing the water) from the regolith on a slope, wildfires decrease the likelihood of a mass wasting event. A wildfire can dry out the regolith on a slope, making it less cohesive and more likely to travel downward. Wildfires burn only at the bottom of a slope, which oversteepens the slope and induces mass wasting. The ash from the wildfires lands on the slope, adding enough mass to instigate mass wasting. Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
