HELPP I PUT MORE POINTS

Answer:

Point-slope:

y - 1 = -2(x - 4)

Slope-intercept:

y = -2x + 9

Standard:

2x + y = 9

Step-by-step explanation:

The equation you were given is:

y = -2x + 7

This is slope-intercept form of the equation. When an eq is in this format you can see (no work!) the slope and the y-intercept (hence the name) Anyway, the number infrontof the x is the slope. Parallel lines have the same slope. So your new equation will also have a slope of -2.

We have a point on the new line, but not the y-intercept, so we need another form of the equation. Point-slope equation is something we can use.

y - y = m(x - x)

in this fill-in-the-blank formula, we put the slope in place of the m. And, given any point on the line (x,y) We fill in the SECOND x and the SECOND y. The FIRST x and y just stay variables.

So, we know the slope is -2.

And a point on the line is (4,1).

Fill in:

y - 1 = -2(x - 4)

This is the least- amount-of-work-for-us, equation of the line.

Sometimes the teacher/book/class/program asks for a specific version of the equation.

y - 1 = -2(x - 4)

Distribute the -2.

y - 1 = -2x + 8

Add 1 to both sides.

y = -2x + 9

This is slope-intercept form of the equation.

Or we can change it to Standard form.

y = -2x + 9

Add 2x to both sides.

2x + y = 9

[tex]\sqrt{113}[/tex] = x

Step-by-step explanation:

In right triangles the sum of square length of two legs is equal to square length of hypotenuse:

7^2 + 8^2 = x^2

49 + 64 = x^2 add like terms

113 = x^2 find the root for both sides

[tex]\sqrt{113}[/tex] = x

The value of 'c' in the 32^{2c} = 8^{c+7}[tex]32^{2c} = 8^{c+7}[/tex] is, 3.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An expression [tex]32^{2c} = 8^{c+7}[/tex].

Now, To equate the exponents we have to change the bases to the same value.

Therefore, [tex]32^{2c} = 8^{c+7}[/tex] ⇒ [tex](2^5)^{2c} = (2^3)^{c+7}[/tex].

5(2c) = 3(c + 7).

10c = 3c + 21.

7c = 21.

c = 3.

Answer:

Step-by-step explanation:

The nth term of an arithmetic progression is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₈ = - 10 , then

a₁ + 7d = - 10 → (1)

The sum of the first n terms of an arithmetic progression is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

Given

[tex]S_{20}[/tex] = - 350 , then

[tex]\frac{20}{2}[/tex] [ 2a₁ + 19d ] = - 350

10(2a₁ + 19d) = - 350

20a₁ + 190d = - 350 → (2)

Multiply (1) by - 20

- 20a₁ - 140d = 200 → (3)

add (2) and (3) term by term to eliminate a₁

0 + 50d = - 150

50d = - 150 ( divide both sides by 50 )

d = - 3

substitute d = - 3 into (1)

a₁ + 7(- 3) = - 10

a₁ - 21 = - 10 ( add 21 to both sides )

a₁ = 11

Then first term a₁ = 11 and common difference d = - 3

(b)

a₁ + (n - 1)d = - 97 , that is

11 - 3(n - 1) = - 97 ( subtract 11 from both sides )

- 3(n - 1) = - 108 ( divide both sides by - 3 )

n - 1 = 36 ( add 1 to both sides )

n = 37

That is the 37th term = - 97

Answer:To get the graph of the given parabola, we will use the equation of the parabola to check if given points in options are lying on that parabola or not. If they lie on the graph of parabola,  then they would satisfy the equation, else not. We will use vertex form of parabola to get its vertex.

The total cost is $450 + $55h.

To calculate the total cost of fixing Yonna's car, we need to consider both the cost of the parts and the labor charges.

1. Cost of parts = $450.

2. Labor charges:

The mechanic charges $55 per hour for labor. We need to know the number of hours the mechanic spends fixing the car to calculate the labor charges.

Let's assume the mechanic spends "h" hours fixing the car.

Labor charges = $55 per hour * h hours = $55h.

The total cost of fixing the car is the sum of the cost of parts and the labor charges:

Total cost = Cost of parts + Labor charges

Total cost = $450 + $55h.

The total cost depends on the number of hours the mechanic spends fixing the car ("h" hours)

The total cost is $450 + $55h.
