What is the solution to the system of equations?
5-
y=-2x+ 6
y=3x +1/
-5

Answer:

X=-6

If satisfied, please mark brainliest

Step-by-step explanation:

-3x+8+5x=-4

Subtract 8 from both sides and add

2x=-12

X=-6

Step 1: Simplify both sides of the equation.

−3x+8+5x=−4

(−3x+5x)+(8)=−4(Combine Like Terms)

2x+8=−4

2x+8=−4

Step 2: Subtract 8 from both sides.

2x+8−8=−4−8

2x=−12

Step 3: Divide both sides by 2.

2x

2

=

−12

Answer:

The expression T = 15*3 + 32  could be used to correctly calculate the amount Roberta owes Mr. Jones

Step-by-step explanation:

Given that:

Amount charged for parts = $32

Per hour labor = $15

Time spent on repairing = 3 hours

Total amount = Per hour labor * Number of hours + Amount of parts

T = 15*3 + 32

Hence,

The expression T = 15*3 + 32  could be used to correctly calculate the amount Roberta owes Mr. Jones

Answer:

$23,800

Step-by-step explanation:

59.5 x 5 x 80 = $23,800

The size 60 will produce the widest 95% confidence interval when estimating the population parameter.

'A confidence interval is the mean of your estimate plus and minus the variation in that estimate.'

According to the given problem,

IN a sample with n number of people surveyed with a probability of a success of [tex]\pi[/tex] and a confidence level of 1-α , we have the following confidence interval of proportions.

[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

In which, z is the z score that has a p value of 1 -(α/2)

The margin of error is:

M = z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

The higher the margin of error, the wider an interval is.

As the sample size increases, the margin of error decreases. If we want, the widest possible interval, we should select the smallest possible confidence interval.

Hence, we can conclude that 60 is the correct answer.

Answer:

Input value/x = 9

Step-by-step explanation:

The output value means y and the input value means x.

So they've told us the output value y = 4.5

Sub this into the function they gave us to get x

y=x/2

4.5=x/2

9=x

Answer:

36

Step-by-step explanation:

The numbers on the bottom are always equal to 1.5 times the number on top.

3 x 1.5 = 4.5, 10 x 1.5 = 15, and so on. 24 x 1.5 = 36, so the missing number is 36.

Step-by-step explanation:

f(x) = x² + 1, where x >= 0.

Let y be f(x).

=> y = x² + 1

=> x² = y - 1

=> x = √(y - 1) because x is non-negative.

Hence f^-1(x) = √(x - 1), where x >= 1.

Answer: 116 Degrees

Step-by-step explanation:

540 is what the pentagon equals! You add up all of the sides, the square equals 90 degrees because it's a right angle. 121+115+98+90 equals 424. You subtract 540 - 424 and you get 116, which is x! Good luck!

Answer:

C. The rate of change of Function 1 is the same as Function 2.

Step-by-step explanation:

The rate of change in an equation is the slope. In this case, function 1's slope is 1/2 and in function 2 - y=1/2x+3,  the slope, or rate of change, is also 1/2. This means that statement C. is correct. Hope this helps :) Good luck!!

Step-by-step explanation:

The cost for River Y is a constant (not dependent upon hours), so is c = 41.

The cost for River Z is the sum of the deposit and the hourly cost, so is ...

 c = 13+4n

These equations and their graphs are shown in the attachment. The graphs cross where n=7, indicating you have to rent a canoe for 7 hours for the cost to be the same on both rivers.

Answer:

21 and 26 totaling 47sticks

Step-by-step explanation:

Th number of sticks form an arithmetic progression

1, 6, 11, 16...

The nth term of an arithmetic progression is expressed as;

Tn = a+(n-1)d

a is the first term = 1

d is the common difference

d = 6-1 = 11-6 = 5

n is the number of terms

The next two terms are the fifth and sixth term

T5 = 1+(5-1)5

T5 = 1+4(5)

T5 = 1+20

T5 = 21

T6 = 1+(6-1)5

T6 = 1+5(5)

T6 = 1+25

T6 = 26

Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks
