Hello! I'm guessing you need someone to solve this equation!

4(5x-6)=2(8x+10)

20x-24=16x+20

Add 24 on both sides!

20x=16x+44

Subtract 16x on both sides!

4x=44

Divide 4 by 44

x=11

m=(Y2-Y1)/(X2-X1)

(1.) m=(2-(-1))/(-2-3) = 3/-5 = -3/5

(2.) m=(-2-1)/(-3-2) = -3/-5 = 3/5  

(3.) m=Infinity (equation: x=-2)

The slopes of the lines passing through the given points are: 1. [tex]\((-2,2)\)[/tex] and [tex]\((3,-1)\)[/tex]: [tex]\(m = -\frac{3}{5}\)[/tex]. 2. [tex]\((-3,-2)\)[/tex] and [tex]\((2,1)\)[/tex]: [tex]\(m = \frac{3}{5}\)[/tex]. 3. [tex]\((-2,-2)\)[/tex] and [tex]\((-2,3)\)[/tex]: The slope is undefined (vertical line).

To calculate the slope m of a line given two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex], you can use the formula:

[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]

Let's apply this formula to the given points:

1. For points (-2,2) and (3,-1):

[tex]\[m = \frac{-1 - 2}{3 - (-2)} = \frac{-3}{5}\][/tex]

2. For points (-3,-2) and (2,1):

[tex]\[m = \frac{1 - (-2)}{2 - (-3)} = \frac{3}{5}\][/tex]

3. For points (-2,-2) and (-2,3):

[tex]\[m = \frac{3 - (-2)}{(-2) - (-2)} = \frac{5}{0}\][/tex]

The slope for the third set of points is undefined because the denominator becomes zero, indicating a vertical line. The first two sets of points have slopes of [tex]\(-\frac{3}{5}\)[/tex] and [tex]\(\frac{3}{5}\)[/tex] respectively.

The sum of the first three prime numbers less than 12 is 2, 3, and 5.

A prime number is a positive integer having exactly two factors that are 1 and number itself. Any number that does not follow this is termed a composite number.

Given

Trisha spins a spinner. the pointer lands on three prime numbers.

She says the sum is less than 12.

The prime numbers are as follows,

2, 3, 5, 7, 11..so on

So the sum of the first three prime numbers will be

2 + 3 + 5 = 10

Hence, the sum of the first three prime numbers less than 12 is 2, 3, and 5.

Answer:

A is the answer

Step-by-step explanation:

The graph of the equation y = -4x+7 is a line that shows the set of all solutions of the equation.

"The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x, y to form an algebraic equation, which is referred to as an equation of a line. Using the equation of any line, we can find whether a given point lies on the line or not.

The equation of line is a linear equation with a degree of one"

"The equation of a line can be formed with the help of the slope of the line and a point on the line."

Here is the equation of the line is given,

y = -4x + 7

since, it is the equation of a line, it contains all the solutions on the graph.

Hence, option A is the correct option.

Answer:

The area of this tabletop is

6 ft. × 2 ft. = 12 ft.²

we know that

To calculate the ideal mechanical advantage for an inclined plane, divide the length of the incline by the height of the incline

Step 1

Find the horizontal distance of the ramp

we know that

the ramp has a slope of [tex]1:10[/tex]

so

by proportion

[tex]\frac{1}{10} \frac{height}{long} =\frac{25}{x} \frac{height}{long} \\ \\x=25*10 \\ \\ x=250\ ft[/tex]

Step 2

Find the length of the incline of the ramp

Applying the Pythagorean Theorem

[tex]incline^{2}=height^{2}+horizontal^{2}[/tex]

substitute the values

[tex]incline^{2}=25^{2}+250^{2}[/tex]

[tex]incline^{2}=63,125[/tex]

[tex]incline=251.25\ ft[/tex]

Step 3

Find the ideal mechanical advantage

[tex]Ideal\ Mechanical\ Advantage=\frac{incline}{height}[/tex]

substitute the values

[tex]Ideal\ Mechanical\ Advantage=\frac{251.25}{25}=10.05[/tex]

therefore

the answer is

the Ideal Mechanical Advantage of the ramp is [tex]10.05[/tex]

The focus is (1,0)  

Hope this helps!

Answer:

focus is (1,0)

Step-by-step explanation:

the focus of a parabola with equation [tex]y^2=4x[/tex]

Focus point lies inside the parabola

To find the focus of a parabola we need to find the vertex

the distance between the focus and vertex is the value of p.

Focus point is (h+p,k)

Where (h,k) is the vertex

Given equation is in the form of [tex](y-k)^2=4p(x-h)[/tex]

Given equation can be written as [tex](y-0)^2=4(x-0)[/tex]

So the vertex is (0,0)

Now we find the value of p

[tex]4p = 4[/tex]

So [tex]p=1[/tex]

Focus is (h+p,k) that is (1,0)

To solve this, first add -9b on both sides of the equation to get the variable on only one side of the equation.

2b+4=-18-9b

2b+9b+4=-18-9b+9b

11b+4=-18

Then subtract 4 from both sides of the equation.

11b+4=-18

11b+4-4=-18-4

11b=-22

Divide 11 on both sides of the equation to find the values of b.

[tex]\frac{11b}{11}[/tex]=[tex]\frac{-22}{11}[/tex]

b=-2

t<-4

Mariana only wears her coat when it is colder than -4 so t must be less than -4.

Answer: t < -4

Step-by-step explanation:

We want to represent temperatures colder than -4 C

In mathematical terms, we want to represent temperatures less than -4 C

t < -4

Solution:

Let starting map of youth center has Dimension (Preimage)

1 unit of y= k units

1 unit of x = t units

The new map of youth center which is 3 times larger than original(Image)

1 unit of y= 3 k units

1 unit of x = 3 t units

Image = 3 × Pre- image

The image is larger than Pre- image.

So, Scale of the new map = 3 × The original dimension of map.

The answer to this question is 380

Answer:

380 dollar.

Step-by-step explanation:

John earns $437 a week after a 15% pay rise.

Let the initially pay of John be x

x + (15% of x) = 437

x + 0.15x = 437

1.15x = 437

x = [tex]\frac{437}{1.15}[/tex]

x = 380

Initially his pay was 380 dollar.

This would be k < 50.

This inequality states that k, the price at which Nita wants to buy the new keyboard, is less than 50 dollars.

Answer:

0 ≤ k ≤ 50

Step-by-step explanation:

Here k represents the price of the keyboard ( in dollars ),

Given,

Nita will buy the keyboard,

If the price of the keyboard is under $ 50,

That is,  [tex]k \leq 50[/tex]

Also, the price can not be negative,

⇒ [tex]0 \leq k[/tex]

Hence, the required inequality is,

[tex]0 \leq k \leq 50[/tex]

Answer:

B) 37%

Step-by-step explanation:

Given,

The total base pay and commission = $ 52561,

While, base pay = $ 23690,

So, the amount of commision = Total base pay and commission - base pay = $ 52561- $ 23690 = $ 28871,

Also, total sale = $77,300,

Hence, the rate of the commission( in percentage )

[tex]=\frac{Commission}{Sale}\times 100[/tex]

[tex]=\frac{28871}{77300}\times 100[/tex]

[tex]=\frac{2887100}{77300}[/tex]

[tex]=37.3492884864\%[/tex]
