Write your answer using integers, proper fractions, and improper fractions in simplest form.​

Answers

Answer:

y = 6x + 3

Step-by-step explanation:

Equation of the line

------------------------------------------------------

The equation of the line in slope-intercept form is:

y = mx + b

Being m the slope and b the y-intercept.

Where m is the slope and (h,k) is a point through which the line passes.

We are given the y-intercept as b=3 m=6.

Thus, the equation of the line is:

y = 6x + 3

Graph 2: modest negative correlation

Graph 3: modest positive correlation

Graph 4: strong positive correlation

Graph 5. weak negative correlation

Step-by-step explanation:

If i'm wrong PLEASE correct me

The graph first is perfect negative correlation, graph second is the modest negative correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

As we know, the coefficient of correlation varies between -1 and +1.

If r = +1 (means the relation between the variable is strong and positive)

If r = -1 (means the relation between the variable is strong but negative)

As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.

So, we can say:

The first graph is perfect negative correlation.

The second graph is modest negative correlation.

The third graph is modest positive correlation.

The fourth graph is strong positive correlation.

The fifth graph is weak negative correlation.

Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.

Step-by-step explanation:

Answer:

[tex]\boxed {\boxed {\sf x \approx 9.7}}[/tex]

Step-by-step explanation:

This is a right triangle, which we know because of the square in the corner of the triangle. We can use the right triangle trigonometric ratios.

[tex]sin( \theta) =opposite/hypotenuse[/tex]  and [tex]cos (\theta) = adjacent /hypotenuse[/tex] and [tex]tan (\theta)=opposite/adjacent[/tex]

First, identify each side of the triangle as adjacent, opposite, or hypotenuse, relative to the 68 degree angle.

The x is next to, or adjacent, to the angle. The 24 is opposite. We are not given the hypotenuse.

[tex]adjacent= x \\opposite= 24 \\hypotenuse= unknown[/tex]

Since we have the adjacent and opposite, we must use tangent.

[tex]tan (\theta)=\frac{opposite}{adjacent}[/tex]

Substitute the values in. The theta (θ) is the angle.

[tex]tan (68)=\frac{24} {x}[/tex]

Solve for x. One way is by cross multiplying.

[tex]\frac{tan(68)}{1}=\frac{24}{x}[/tex]

Multiply the 1st numerator by the 2nd denominator. Then, multiply the 1st denominator by the 2nd numerator.

[tex]tan (68)*x=1*24[/tex]

[tex]tan(68)*x=24[/tex]

Evaluate tan(68) using a calculator.

[tex]2.47508685*x=24[/tex]

Divide both sides of the equation by 2.47508685. This will isolate the variable x. ( We divide because multiplication is occurring between 2.47508685 and x, and division is the inverse of multiplication).

[tex]\frac{2.47508685*x}{2.47508685}=\frac{24}{2.47508685}[/tex]

[tex]x=\frac{24}{2.47508685}[/tex]

[tex]x=9.69662943[/tex]

Round to the nearest tenth. The 9 in the hundredth place tells us to round up. The 6 becomes a 7.

[tex]x \approx 9.7[/tex]

In this right triangle, x is equal to about 9.7

1. What can you say about the value of a polynomial
when P(a)=0

Answers

Answer:

The expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Step-by-step explanation:

The question would be better answered if you gave option. Since there is no option, I'll answer the question generally.

Given

[tex]P(a) = 0[/tex]

The above expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Take for instance, the polynomial is:

[tex]P(x) = x^2 - x - 2[/tex]

And the divisor is x - 2, then P(2) = 0 because (x - 2) is a divisor of the equation.

[tex]\frac{P(x)}{x} =\frac{x^2 - x - 2}{x - 2}[/tex]

Factorize the numerator

[tex]\frac{P(x)}{x} =\frac{(x- 2)(x + 1)}{x - 2}[/tex]

[tex]\frac{P(x)}{x} =x + 1}[/tex]

See that x - 2 is a divisor

To check

Set x - 2 to 0

[tex]x -2 = 0[/tex]

[tex]x = 2[/tex]

So, we have:

[tex]P(x) = x^2 - x - 2[/tex]

[tex]P(2) = 2^2 - 2 - 2[/tex]

[tex]P(2) = 4 - 2 - 2[/tex]

[tex]P(2) = 0[/tex]

Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on.

In the answer box,
Write a system of equations to describe this scenario. Identify what the variables mean in the context of the problem.

Answers

Answer:

If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.

For Hana, you will have 3+ 3/4 x

Step-by-step explanation:

First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.

The system of equations to describe this scenario are

y = 3 + 7xy = 9 + 4x

The variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .

The situation can be modelled like a linear equation.

Therefore,

y = mx + b

where

m = slope

b = y-intercept

Cora race will be as follows:

y = 3 + 7x

Hana race will be as follows:

y = 9 + 4x

The variable x which is the independent variable is the number of weeks each of them ran in the equation.

The variable y which is the dependent variable is the total distance covered in miles.

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..​

Answers

Answer:

y < 3x + 5: No

y = 3x + 5: No

y > 3x + 5: Yes

Step-by-step explanation:

You can just put the value of x which is (-2) into each equation to see if the y value would be 4.

y < 3x + 5

y < 3(-2) + 5

y < -6 + 5

4 < -1 (This equation is wrong, so the point does not satisfy this equation)

y = 3x + 5

y = 3(-2) + 5

y = -6 + 5

4 = -1 (This equation is wrong, so the point does not satisfy this equation)

y > 3x + 5

y > 3(-2) + 5

y > -6 + 5

4 > -1 (This equation is correct, so the point does satisfy the equation)

~ FIRST: you have to MULTIPLY both of your SIDES by 5

1n/5 • 5 = 7 • 5

~ CANCEL out; 1/5 • 5 because that gives you a 1
~KEEP: 7 • 5 because it gives the value of your “n”

New equation: n = 7 • 5

7 • 5 = 35

Answer: n = 35 ☑️

Regular division problem: 35/5 = 7 so this makes it true!

A pyramid is made above a cuboid with measure 90cm×50cm×225cm. If the height of the pyramid including cuboid is 240cm, find the total volume.​

Answers

Answer: whatever do I care

Step-by-step explanation: I don’t care

The required volume of the pyramid is, 22500 cubic cm.

What is volume?

Volume is referred to as the area occupied within an object's three-dimensional space.

Given that,

The length of cuboid = 90 cm

Width of cuboid = 50 cm

And height of cuboid = 225 cm

Let the height of the pyramid is x cm

Since the height of cuboid and pyramid = 240 cm

⇒ 225 + x = 240

⇒ x = 15 cm

Since the base of pyramid will be the same as the base of cuboid,

The volume of pyramid = 1/3 x base area x height

                                       = 1/3 x 90 x 50 x 15

                                       = 22500

The volume of the pyramid is 22500 cubic cm.

Answer:

y = [tex]\frac{2}{5}[/tex] x + 2

Step-by-step explanation:

Graph below.

Answer:

y = 2/5x + 2

Step-by-step explanation:

y = mx + b

First, we find out the slope. The slope is the change in y over the change in x.

The change in y is the second y-value subtracted from the first. The first y-value is 0 and the second is 2.

0 - 2 = -2

The change in x is the second x-value subtracted from the first. The first x-value is -5 and the second is 0.

-5 - 0 = -5

The slope is the change in y over the change in x.

-2/-5 = 2/5

y = 2/5x + b

b is the y-intercept, which is the value of y when x = 0.

When x = 0, y = 2 (0,2), so b = 2.

y = 2/5x + 2
