Example question: There are 38 students in a baseball club. The coach needs to split them up into equal groups of 4. How many groups can be made? How many kids are left over?
Answer: You would make groups of 4 to get your quotient (9). Then whatever is NOT in a group is your left over.

Write the inverse of the function: f (x) = 2x+3

34kurt

Answer:

$y = \frac{x - 3}{2}$

Step-by-step explanation:

To find the inverse of a function, simply 'switch' the x and y's and solve for y. $y = 2x + 3$ becomes $x = 2y + 3$ . Now, solving for y, we get $y = \frac{x - 3}{2}$ .

hope this helped! :)

Compute each sum below. If applicable, write your answer as a fraction.

Alex777 [14]

Answer:

First equation is -425

Second equation is 11.25

Step-by-step explanation:

First equation we can write as

$\sum_{i=0}^7 5 \times (-2)^i$

computing

When i=0 -> $5 \times (-2)^0 =5$

When i=1 -> $5 \times (-2)^1 = -10$

...

When i=7 -> $5 \times (-2)^7 = --640$

then replacing each term we have

$5 + (-10) + ( 20) + ( -40) + (80) +( -160) + 320 + (-640) = -425$

For the second equation we'll have 9 terms, solving in a similar fashion

When i=1 -> $\frac{1}{4}1=0.25$

When i=2 -> $\frac{1}{4}2=0.50$

When i=3 -> $\frac{1}{4}3=0.75$

...

When i=9 -> $\frac{1}{4}9=2.25$

So we have 0.25 + 0.50 + 0.75 + 1.00 + 1.25 + 1.50+ 1.75 +2.00 +2.25

Bo has $500 in his savings account. He plans to add $150 to his savings account every month. Recently, he purchased a tractor to

MariettaO [177]

Answer:

A. $2,000

Step-by-step explanation:

Assuming that the money in the savings account will be used to pay off for tractor.

let the number of months be m

Savings after m months will be 500+ 150m

After m months the installments paid will 200m

To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:

500+150m +200m = 4000

150m + 200m = 4000-500 (grouping like terms)

350m = 3500 (Making m the subject of the formula)

350m/350 = 3500/350

m = 10

Substituting m into the equation of saving after m months

Savings after m months will be 500+ 150m

Savings after m months will be 500 + 150(10)

Savings after m months will be 500 + 1500

Savings after m months will be $2000

Identify the inequality that represents the graph. Please help!

Lesechka [4]

Answer:

B.

Step-by-step explanation:

Since we have a dotted line, our inequality must be either < or >, so A and D are out. We are left with B and C. Since our line is positive, our answer must be B and not C.

Alternatively, you can graph each equation and choose the best answer that matches the graph.
