where is y=5x on a graph ???

Provided the figures we have that describe the mass of Earth and the mass of Jupiter, we can conclude that Jupiter is 318 times greater than the mass of Earth.

From the figures we have, we can see that the mass of Jupiter is greater than the mass of Earth because it has more zeros.

So, we have to divide the value of the mass of Jupiter by the mass of the earth as follows:

1.9 x 10^27

5.97 X 10^24

=1. 9 ÷ 5.97 × 10^27 - 10^24

= 0.318... ×10³

= 318

Do note that when we have to divide figures that are raised to some figures, the rule will be to subtract the figures as we find in the fact that 27 - 24 is equal to 3. And when we multiply, we arrive at the stated figure.

The value of Chrissy's height from the problem is 76

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

Let x represent Chrissy's height. 55 is the difference of Chrissy's height and 21. Hence:

x - 21 = 55

x = 76

If Roni has a riding lawn mower and can mow the field in 30 minutes and  Allie is pushing a lawn mower and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, about 0.71 of the field will Roni mow.

Time taken by Roni to mow the field = 30 minutes

Time taken by Allie to mow the field = 75 minutes

Work done by the Roni = x/30

Word done by Allie = x/75

Then they are working together

x/30 + x/70 = 1

Solve the equation

[tex]\frac{70x+30x}{2100}=1[/tex]

70x+30x = 2100

100x = 2100

x = 2100/100

x  = 21

Then, the work done by Roni = x/30

= 21/30

= 0.70

Hence, if Roni has a riding lawn mower and can mow the field in 30 minutes and  Allie is pushing a lawn mower and can mow the field in 75 minutes. If Roni and Allie work together to mow the field, about 0.71 of the field will Roni mow.

Maggie's mistake on the solution of the expression for x was when she subtracted 7x to both sides, the result should have been -3x and not 3x.

The equation is given as follows, as the angles are congruent, that is, they have the same measure:

4x + 2 = 7x - 25.

First, we isolate x on the left side of the equality, subtracting 7x from both sides, hence:

4x + 2 - 7x = 7x - 25 - 7x

Then the correct expression is:

-3x + 2 = -25

Which is where Maggie's mistake happened, on the subtraction of 4x and 7x.

Then, isolating x, we subtract 2 from both sides of the equality, to remove the +2 term on the left side of the equality.

-3x = -27

3x = 27

x = 27/3

x = 9.

The correct solution is x = 9.

Using division we can calculate that 8 books can fit in the 14 inch long bookshelf .

Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number. Multiplication, addition, and subtraction make up the remaining operations.

length of book shelf = 14 inch

length of each book = 1 3/5 inch = 1.6 inches

Number of books = 14 ÷ 1.6 = 8.75 books

Hence by division we get that 8 book can be put in the  bookshelf.

The sinusoidal function that matches the graph given is:

g(x) = 4cos((π/7)x) - 2.

The cosine function is defined as follows:

g(x) = acos(bx)+d.

The coefficients have these following roles:

For this problem, we use a cosine function because the function is not zero at the origin, while for the sine it is.

From the graph of this function, the maximum value is of 2, while the minimum value is of -6, hence the amplitude is found as follows:

2a = 8 (difference between these values).

a = 4.

Then:

g(x) = 4cos(bx) + d.

A function with amplitude of 4 should oscillate between -4 and 4, while this one oscillates between -6 and 2, meaning that it was shifted 2 units down, hence d = -2 and:

g(x) = 4cos(bx) - 2.

The period is of 14 units, hence:

2π/b = 14

14b = 2π

b = π/7

Hence the function is:

g(x) = 4cos((π/7)x) - 2.

The value of x is 9 and the mistake that Maggie made is that she did use the proper operation sign when rearranging the numbers.

When any two straight lines intersect each other, then four angles are formed. The angles that are directly opposite to each other are known as opposite angles. They are also called vertical angles or vertically opposite angles.

Now, from the image attached, we see that the two given angles are opposite angles and as such they are congruent. Thus, we have;

4x + 2 = 7x - 25

Rearrange to collect like terms on same side to get;

7x - 4x = 25 + 2

3x = 27

x = 27/3

x = 9

Answer: Ray BA and Ray BC

Explanation:

A ray starts at at a fixed point and moves forever in one direction. If we break line AC into two parts BA and BC, then we can form two opposite rays. Another ray points to the right but the letter marked for this isn't clear, so I'm not sure what to write for that ray. Same goes for the dashed ray that points to the left.

BD is a segment because both endpoints are fixed. We don't have either side extending forever in that direction.
