What is the equation of the line that passes through (-1, -7) and has a slope of 2?

Answer:

[tex]\displaystyle y=\frac{45}{7}[/tex]

Step-by-step explanation:

Direct Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

[tex]\displaystyle \frac{y}{x}=k[/tex]

Where k is a constant.

We know y=25 when x=140, and it's required to find the value of when x=36.

For any pair of values (x,y), their ratio is constant:

[tex]\displaystyle \frac{25}{140}=\frac{y}{36}[/tex]

Multiplying by 36:

[tex]\displaystyle y=36*\frac{25}{140}[/tex]

[tex]\displaystyle y=\frac{900}{140}[/tex]

Simplifying:

[tex]\mathbf{\displaystyle y=\frac{45}{7}}[/tex]

Answer:

$64.00

Step-by-step explanation:

Company A:

C = 3.25x

3.25 x 80 = 260

Company B:

C = 2.45x

2.45 x 80 = 196

How much more?

260 - 196 = 64

Difference in Total price for 80 unit is $84

Per spirit cost in company A = 3.5 per spirit

Cost equation for company B = C = 2.45x

Difference in Total price for 80 unit

Difference in Total price for 80 unit = 80[3.5 - 2.45]

Difference in Total price for 80 unit = 80[1.05]

Difference in Total price for 80 unit = $84

Answer:

6°F

Step-by-step explanation:

Given that:

Temperature at 11pm = 48°F

Temperature at 7am = 6° cooler

Temperature at 11am = 48°F

Number of degrees temperature changed from 7am to 11 am

Exact temperature at 7am = (temperature at 11 pm - 6°)

= 48°F - 6°F

= 42°F

Temperature change from 7am to 11am

Temperature at 11 am - temperature at 7am

48°F - 42°F

= 6°F

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

seven more than four times a number is fifteen -    4n+7=15

one-fourth the difference of a number and 15 -      1/4 (n-15)

one fourth a number decreased by 15 -      1-4 n - 15

the quotient of a number and seven is four -    n divided by 7 = 4

a number raised to the power of four increased by 7 is 15 -   n to the power of 4 - 7=15

Step-by-step explanation:

Answer:

A

-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)

Step-by-step explanation:

I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))

Answer:

69.498

Step-by-step explanation:

first find the area of the whole square (how i saw it), remember

it is made up of a circle drawn inside a square.

so we do the area of the square = 18²

= 324

next we find the circle which was drawn, the circle covers up the

whole shaded square.

diameter would be 18 as the length of the square was 18,

then we find the radius, 18/2 = 9

now we use πr²,

r would be the radius  (9)

therefore it would be π(81) and we get 254.502

now we take away the area of the circle covering the square

from the area shaded in,

therefore  324 - 254.502

= 69.498

Answer:

c = 5

Step-by-step explanation:

a²+b²=c²

(3)²+(4)²=c²

9+16=c²

25=c² square root on both sides

5=c

c=5

Answer:

All of the options are in standard form (ax+by=c). But none of the answers is an option. The correct answer is x+4y=8.

Step-by-step explanation:

The following screenshot is a graphing website to prove that the equation x+4y=8 passes through the points (4,1) and (20,-3).

I don’t know if the equation x+4y=8 is an option for you, because I don’t see it as an option to choose out of the four.

But I hope this helps and answers your question :)

Step-by-step explanation:

4x^2 + 20 = 0

divide 4 throughout:

x^2 + 5 = 0

x^2 = -5

x = ±√-5

However, you can't square root a negative number as it is a complex number / imaginary number hence you would want to conclude it as "no solution"

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x  equals 2.

Step-by-step explanation:

here is a step by step equation:

f(x) = x + 7

if:

x=2

then:

f(2) = 2 + 7 = 9

A function is linear if it can be defined by

f(x) = mx + b

Makes sense? Hope I helped

Answer:

If kyle keeps the money in the account for 4 years, the new balance is $1,417.37.

Step-by-step explanation:

You can use the formula to calculate the future value to find the money in the account after 4 years:

FV=PV*(1+i)^n

FV= future value

PV= present value=$1,200

i= interest rate=4.25%=0.0425

n=number of periods of time=4

FV=1,200*(1+0.0425)^4

FV=1,200*(1.0425)^4

FV=1,417.37

According to this, the answer is that if kyle keeps the money in the account for 4 years, the new balance is $1,417.37.
