HELP!
Ella swims four times a week at her club’s pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps on Saturday. She swims a total of 51 laps each week. Write an equation for the problem.

Answer:

Band A:y=700

Band B:y=550+1.50x

Step-by-step explanation:

Band A: since they are a fixed rate no matter how many students the equation  would be y=700 . There is no need for x since there is no extra price for students

Band B: Since this band charges 550 plus 1.50 per student we will need a x in our equation

y=550+1.50x

The difference between the two equations is that in Band B we need to add the price per student.

Answer:

t = 39

Step-by-step explanation:

the diagonals of a parallelogram bisect each other, therefore t = 3t - 78 further solving this equation we get

2t = 78 and then t = 39

Answer:

k = 0

Step-by-step explanation:

On the graph, the second point would be at (-7,0)

Answer:

k = 0

Step-by-step explanation:

We can find the answer to this question by using the slope equation:

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

Let's define some variables:

[tex]\frac{k - 7}{-7-(-8)} = \frac{k-7}{1} = k- 7[/tex]

We know the slope is -7 so we can put k-7 equal to it and solve

[tex]k-7 = -7\\k = 0[/tex]

We find that k is equal to 0.

I hope this helps!!

Answer:

The system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture is:

p + c = 6....... Equation 1

4p + 5c = 4.40(6)....... Equation 2

Step-by-step explanation:

A health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound. Which system of linear equations can be used to determine the number of pounds of each dried fruit in the mixture?

Let the number of pounds of dried peaches = p

the number of pounds of dried cherries = c

We are told: health food store sells dried peaches (p) for $4 per pound and dried cherries (c) for $5 per pound. A six pound mixture of the two dried fruits cells for $4.40 per pound.

Hence: The system of equations is given as:

p + c = 6...... Equation 1

$4× p + $5 × c = $4.40(6)

4p + 5c = 26.4.......Equation 2

Answer:

B

Step-by-step explanation:

The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.

Given:

The given expression is:

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]

To find:

The equivalent expression.

Explanation:

We have,

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]

On simplification, we get

[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]

[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]

[tex]=12(x^{8})(5)[/tex]

[tex]=16x^{8}[/tex]

Therefore, the correct option is B.

Answers:

f(0) = 1

f(2) = 5

============================================

Explanation:

Determining f(0)

The y intercept point (0,1) indicates that x = 0 and y = 1 pair up together. Recall that y = f(x), which means f(x) = 1 when x = 0. This is shortened to f(0) = 1.

-----------------

Determining f(2)

Start at 2 on the x axis. Draw an arrow pointing directly upward until you get to the curve. See the diagram below. Then move to the left until you hit the y axis. You should arrive at y = 5.

This tells us x = 2 and y = 5 pair up together. Therefore, f(2) = 5.

Step-by-step explanation:

We move all terms to the left:

1-(2x+4)-(-4x+5)=0

We get rid of parentheses

-2x+4x-4-5+1=0

We add all the numbers together, and all the variables

2x-8=0

We move all terms containing x to the left, all other terms to the right

2x=8

x=8/2

Step-by-step explanation:

1) Keep, Change, Flip.

-We keep the first number the same, the ÷ (division) sign is changed into a X (multiplication) sign.

3/5 x 10/7

-The 7/10 is flipped and is now 10/7.

2) Now we multiply the top and bottom numbers.

30/35

3) Simplify.

30/35 = 6/7

Step-by-step explanation:

If baseball team scored 5 more runs in its second game than its first. The team scored twice as many runs as the first game in the third game. The total number of runs in all three games was 29.Then 11 runs were scored in the second game

Two or more expressions with an Equal sign is called as Equation.

Let the runs scored by team in first game be x.

The team scored 5 more runs in its second game than its first.

x+5

The team scored twice as many runs as the first game in the third game.

2x

The total number of runs in all three games was 29

This we can write as x+x+5+2x=29

Add x variable terms

4x+5=29

Subtract 5 on both sides

4x=24

x=6

So the score in the second game will be x+5=6+5=11

Hence, 11 runs were scored in the second game

Answer:

(13, 11)

Step-by-step explanation:

I graphed the line and the vertex is at 13, 11

The vertex of the function  f(x) = |x - 13| + 11 is (13,11)

The function is given as:

f(x) = |x - 13| + 11

The above function is an absolute value function

An absolute value function is represented as:

f(x) = a|x – h| + k

Where, the vertex is (h,k)

So, we have:

(h,k) = (13,11)

Hence, the vertex of the function  f(x) = |x - 13| + 11 is (13,11)
