Which ordered pair is a solution to the system of equations?
y=4x
y= 3x + 2

Answer:

6y-2y=3y+2

4y=3y+2

4y-3y=2

1y=2

y=2

Answer:

negative

Step-by-step explanation:

Answer:

D. y = (3/4)x + 10

Step-by-step explanation:

since it has to be in a formula of y = mx + b, it can't be a or b

y - 4 = 3/4 (x + 8)

y - 4 = (3/4)x + 6

y = (3/4)x + 10

Step-by-step explanation:

Answer:

160

Step-by-step explanation:

We have, 15% × x = 24

or,

15

100

× x = 24

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 24 ×

100

15

x = 160

If you are using a calculator, simply enter 24×100÷15, which will give you the answer.

Answer:

C) 160

Step-by-step explanation:

Let the number be x

15% of x = 15/100 * x

15/100 * x = 24

x = 24*100 / 15

x = 160

Answer:

Equation is y = 1/2x + 1

Step-by-step explanation:

First off we know the slope, it is 1/2, so that is done already. Now we just need the y-intercept. In order to cross (4, 3), in needs to have a y-intercept of 1. So the equation is y = 1/2x + 1. I hope this helps, and I hope it's not wrong, but I don't think it is.

Answer:

here's an example to help you out man Let n = how much each new member must pay each month.

$160 - $28 = $132

n = $132 ÷ 12 months in a year

n = $11

You can also look at it this way:

n = (160 - 28)/12

Answer:

y = a ÷ (πx)

Step-by-step explanation:

An equivalent equation solved for y is:

y = a/πx

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

The formula a = xy, where x and y are the halved lengths of the ellipse's biggest and smallest diameters, may be used to calculate the area, a, of an ellipse.

Starting from the formula a = πxy, we can rearrange it to solve for y:

a = πxy

Dividing both sides by πx, we get:

a/πx = y

y = a/πx

Therefore, an equivalent equation solved for y is:

y = a/πx.

Answer: I think it's D.

Step-by-step explanation:

I'm on the same thing and my best answer is Both functions are increasing, but function g increases at a faster average rate.

Both functions are increasing, but function g increases at a faster average rate.

x         f(x)

-2        -46

-1         -22

0         -10

1           -4

2          -1

If the slope of a function is continuously increasing or constant in an interval, the function is known as an increasing function.

Let us assume [tex]f(x)=ab^x+c[/tex]

at x=0, f(0)=-10

So, [tex]-10=a+c[/tex]

Similarly, by satisfying the above table in the f(x)

[tex]f(x)=-\frac{33}{5} (\frac{1}{11} )^x-\frac{17}{5}[/tex]

[tex]f'(x) > 0[/tex]

So we can say that f(x) is an increasing function.

[tex]g(x)=-18(\frac{1}{3} )^x+2[/tex]

[tex]g'(x)=-18(\frac{1}{3} )^xln(\frac{1}{3} )[/tex]

[tex]ln\frac{1}{3} < 0[/tex]

So, [tex]g'(x) > 0[/tex]

So, g(x) is an increasing function.

For any x∈f(x) and  x∈g(x) [tex]g'(x) > f'(x)[/tex]

So, g increases at a faster average rate

Thus,  Both functions are increasing, but function g increases at a faster average rate.

              x = 2 − 3/2y

              y = 4/3 - 2/3x

2x + 3y = 4

Answer:

Step-by-step explanation:

given data

let the number of year be x

le the total cost b y

for the older car

cost of repair $1200

cost of gas  $2,000.00  per year

the cost for using the old car is

y=1200+2000x-----------1

for the new car

cost of $4500

cost of gas  $1,500.00 per year

y=4500+1500x-----------2

equating 1 and 2 we have

1200+2000x=4500+1500x

solving for x

Answer:

-33/56

Step-by-step explanation:

suppose: A,B are the 2 angles of a triangle

we have: A = arcsin[tex]\frac{-4}{5}[/tex]

               B = arctan [tex]\frac{5}{12}[/tex]

=> sin A = [tex]\frac{-4}{5}[/tex] => cos A = [tex]\sqrt{1-\frac{(-4)^{2} }{5^{2} } } =\frac{3}{5}[/tex] (because A is in quadrant IV)

    tan B = [tex]\frac{5}{12}[/tex]

have:

[tex]1+ cot^{2}B=\frac{1}{sin^{2}B } => 1+\frac{1}{tan^{2} B}=\frac{1}{sin^{2}B } \\=> 1+\frac{1}{\frac{5^{2} }{12^{2} } } =\frac{1}{sin^{2}B }\\ => sin^{2}B=\frac{25}{169}[/tex]

because B is in quadrant III => [tex]sin B=-\sqrt{\frac{25}{169} }=\frac{-5}{13}=>cosB=-\sqrt{1-\frac{5^{2} }{13^{2} } }=\frac{-12}{13}[/tex]

tan(arcsin(-4/5)+arctan(5/12)) = tan( A + B)

but A,B are the 2 angles of a triangle => tan(A + B) = [tex]\frac{sin(A+B)}{cos(A+B)}[/tex]

have: sin(A+B) = sinA.cosB + cosA.sinB = [tex]\frac{-4}{5}.\frac{-12}{13} +\frac{3}{5}.\frac{-5}{13}=\frac{33}{65}[/tex]

cos(A + B) = cosA.cosB - sinA.sinB =[tex]\frac{3}{5}.\frac{-12}{13}-\frac{-4}{5}.\frac{-5}{13}=\frac{-56}{65}[/tex]

=> tan(A + B) = [tex]\frac{33}{65}:\frac{-56}{65}=\frac{-33}{56}[/tex]

Answer:

[tex]h(f(x)) = 18x -22[/tex]

Step-by-step explanation:

Given

f (x) = [tex](3x-5)^3[/tex]

[tex]h(x) =2\sqrt[3]{3x} + 8[/tex]

We are to find the composite function [tex]h(f(x))[/tex]

[tex]h(f(x))[/tex][tex]= h ((3x-5)^3)[/tex]

To get [tex]h ((3x-5)^3)[/tex], we will substitute x as (3x-5)³ in h(x)as shown:

[tex]h(x) =2\sqrt[3]{3(3x-5)^3} + 8\\h(f(x)) =2(3(3x-5)+ 8\\h(f(x)) = 2(9x-15)+8\\h(f(x)) =18x-30+8\\h(f(x)) = 18x - 22[/tex]

Answer:

a) Time left = [45 - (3j + 5s)] minutes

b) 17 minutes

Step-by-step explanation:

a) Using j for the number of laps she jogs and s for the number of times she stretches. Since Bailey has a total of 45 minutes to complete his exercise, then;

Time left = [45 - (3j + 5s)] minutes

If she jogs 6 laps and stretches 2 times , then;

Time left = [45 - (3j + 5s)]

b) Where j = 6 and s = 2,

Time left = 45 - (3(6) + 5(2))

              = 45 - (18 + 10)

              = 45 - 28

              = 17

Amount of time Bailey has left is 17 minutes.

Step-by-step explanation:

Number of eggs laid per week = between 18 and 25

Let x = exact number of eggs laid

Using inequality :

18 ≤ x ≤ 25

Number of eggs Pat eats = 2

18 - 2 ≤ x ≤ 25 - 2

Eggs left after pat eats 2 of the eggs :
