Can you help me solve for y ?? Please show your work !! Thank you.

Answer:

[tex]y=6x+-45[/tex]

Step-by-step explanation:

Given the following question:

Point A = (10, 15) = (x1, y1)
Point B = (8, 3) = (x2, y2)

To find the answer we first must find the slope which we will find by using the formula for slope or rise over run. Then we use the formula for slope intercept, substitute the values, and then solve for b.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{3-15}{8-10}[/tex]
[tex]3-15=-12[/tex]
[tex]8-10=-2[/tex]
[tex]=\frac{-12}{-2} =-12\div-2=6[/tex]
[tex]m=6[/tex]

Now we have the slope find the slope intercept:
[tex]y=mx+b[/tex]
[tex]y=15[/tex]
[tex]m=6[/tex]
[tex]x=10[/tex]
[tex]15=6(10)+b[/tex]
[tex]6\times10=60[/tex]
[tex]15=60+b[/tex]
[tex]60-60=0[/tex]
[tex]15-60=-45[/tex]
[tex]-45=b[/tex]
[tex]b=-45[/tex]
[tex]y=6x+-45[/tex]

Your answer is "y = 6x + -45."

Hope this helps.

By finding the quotient between the volumes, we will see that 24 books can be fit on the container, and by weight, the container can hold 20 books.

Remember that the volume of a rectangular prism of length L, width W, and height H is given by:

V = L*W*H

Then the volume of each book is:

V = 6in*2in*8in = 96 in^3

And the volume of the container is:

V' = 16in*12in*12in = 2,304 in^3

The number of books that fit in the container is given by:

N = V'/V = 2,304 in^3/96 in^3 = 24

Each book weighs 2 pounds, and the container can hold 40 pounds, then we need to solve the linear equation:

2*x = 40

To get the maximum number of books that the container can hold:

x = 40/2 = 20

x = 20

The container can hold a maximum of 20 books.

Answer:

$68.25

Step-by-step explanation:

1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.

2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.

Therefore, the cost of 3 sweatshirts is $68.25.

Each t-shirt  cost 13 dollars.

Step-by-step explanation:

Since the jacket was 20 bucks, we can set that aside:

85-20=65

Now that we've set that aside, there are five t-shirts. If they all cost the same, that means we can divide!

65/5=13

How to check?

Use inverse operations: 13*5=65

Re-add the 20 bucks from the jacket, and the bill is complete again! Use inverse operations: 13*5=65

Answer: $ 14.32

Step-by-step explanation:

Answer:

d and b

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 8 , then

sum = 180° × 6 = 1080°

note there are 4 angles congruent to ∠ 1 and 1 angle congruent to ∠ 2

sum the interior angles and equate to 1080

5(10x + 15) + 2(14x) + 6x - 3 = 1080 ( distribute parenthesis on left side )

50x + 75 + 28x + 6x - 3 = 1080 ( simplify left side )

84x + 72 = 1080 ( subtract 72 from both sides )

84x = 1008 ( divide both sides by 84 )

x = 12 → option d

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

∠ 1 = 10x + 15 = 10(12) + 15 = 120 + 15 = 135°

∠ 2 = 14x = 14 × 12 = 168°

∠ 3 = 6x - 3 = 6(12) - 3 = 72 - 3 = 69°

the largest interior angle is 168° → option b

Image result for Identify the vertex of the following parabola. y = x2 - 4x +1

To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.

Answer:

20

Step-by-step explanation:

Let's start by rewriting the second equation in terms of "x":

[tex]x+y=5[/tex]

Subtract y from both sides:

[tex]x=5-y[/tex]

Now, substitute "5-y" for "x" in the first equation:

[tex](5-y)^2-y^2=100[/tex]

Note that:

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]25-10y+y^2-y^2=100[/tex]

Cancel out like terms:

[tex]25-10y=100[/tex]

Subtract 25 from both sides:

[tex]-10y=75[/tex]

Divide both sides by -10

[tex]y=\frac{75}{-10}=\frac{15}{-2}=-\frac{15}{2}[/tex]

Now, substitute this value back into either of the equations to solve for x.

[tex]x+y=5\\x-\frac{15}{2}=5\\[/tex]

Add 15/2 to both sides:

[tex]x=5+\frac{15}{2}\\x=\frac{10}{2}+\frac{15}{2}\\x=\frac{25}{2}[/tex]

Now, find the difference:

[tex]x-y=\frac{25}{2}-(-\frac{15}{2})=\frac{25}{2}+\frac{15}{2}=\frac{40}{2}=20[/tex]

To get to the desired conclusion, you will want to make use of CPCTC and the fact that triangle AXB is congruent to triangle CYD. In order to show those two right triangles are congruent, it is sufficient to claim congruence of their hypotenuses and one internal acute angle (HA congruence). The corresponding internal angles are alternate interior angles where a transversal (BD) crosses parallel lines (AB║CD). It's tedious, but not terribly difficult.

Additional comment

A lot of proof has to do with working backward, answering the question, "How do I know ...?" The beginning paragraph in this answer attempts to show you the answers to those questions.

This proof works with the smaller triangles AXB and CYD. You could do the same proof with the larger triangles AXD and CYB. For that, you'd have to claim that AD║BC.

The equation that can be used to find x in the triangle is x + 86 = 180

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Therefore, let's find the angle of x in the triangle.

Triangle DEF is shown above. Therefore, the equation that can be used to find the value of x can be calculated as follows:

49 + 37 + x = 180

Therefore, the equation is as follows:

x + 86 = 180

An equation that could be used to find the value of x is: B. x + 86° = 180°.

In Mathematics and Geometry, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.

Additionally, the sum of all of the interior angles of a triangle is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of the given angles are supplementary angles:

m∠1 + m∠2 + m∠3 = 180°

37° + 49° + m∠3 = 180°

86° + m∠3 = 180°

x + 86° = 180° (required equation)

Answer:

0.44

Step-by-step explanation:

See the picture below.

Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.

Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.

For angle J, leg LK is the opposite leg.

The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.

[tex]\sin J = \dfrac{opposite~leg}{hypotenuse}[/tex]

SOLUTION: It would take about 4.7 hours if they worked together.

Step-by-step explanation:

The equation has two solutions. Means Discriminant means b^2-4ac >0

Here b = a.

a = 1

c = b

a^2 - 4b >0

a=2

b= -1

then a^2 - 4b > 0 = 4+4 > 0

therefore its 2, -1

The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.

We have,

Given that the equation x² + ax + b = 0 has solutions a and b, the sum and product of the roots (a and b) can be related to the coefficients of the quadratic equation.

The sum of the roots of a quadratic equation is given by:

Sum of roots = -coefficient of x / coefficient of x² = -a

The product of the roots of a quadratic equation is given by:

Product of roots = constant term / coefficient of x² = b

From the given information, we have:

The sum of roots = a

Product of roots = b

Thus,

The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.
