Answer:

Photo 1: x=5 y=-2

Photo 2: x=11/5 y=4

Step-by-step explanation:

Photo 1-

2x + 3y = 4

              x = 2 − 3/2y

              y = 4/3 - 2/3x

2x + 3y = 4

              x = 2 - 3/2y

              y = 4/3 - 2/3x

Photo 2-

5x + 3y = 23

              x = 2 − 3/2y

              y = 4/3 − 2/3x

3y = 15x - 21

              x = y/5 + 7/5

              y = 5x − 7

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:

45 lessons

Step-by-step explanation:

Here, we want to know the number of lessons that both of them would have completed when they earn pizza and cookies at the same time

From the question, we are told that they earn cookies and pizza when they complete 9 and 15 lessons respectively.

So to know the number of lessons completed, we need to find the lowest common multiple of the number of cookies and the numbers of pizza

That will be lowest common multiple of 9 and 15

This is 45

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:

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.

1y=2

y=2

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:

Step-by-step explanation:

A: +2

B: +2

C: -25

D: x3

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.

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:

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

1200-4500=1500x-2000x

-3300=-500x

x=3300/500

x=6.6

The number of years is 6 years 6 months
