Answers

Answer 1

Answer:

B. The equation has infinitely many solutions.

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

2(x + 4) = 6x + 6 - 4x + 2

Step 2: Solve for x

Combine like terms:                    2(x + 4) = 2x + 8Distribute 2:                                  2x + 8 = 2x + 8Subtract 8 on both sides:            2x = 2xDivide 2 on both sides:                x = x

Here we see that any number x can be used and will render the equation true. Therefore, x = infinite amount of solutions.

Find the equation of a line whose slope is one-half and y-intercept is 2.

Answers

Answer:

[tex]y=\frac{1}{2} x+2[/tex]

Step-by-step explanation:

To find this you can use slope-intercept form which is y=mx+b where m=slope and b=y-intercept. You just have to plug both numbers in, giving you [tex]y=\frac{1}{2} x+2[/tex].

The equation of a line is y=mx+c
Where m is the gradient and c is the y intercept
If you substitute m with 0.5 and c with 2 the answer will be y=0.5x+2

Find the x-intercept of the graph of the equation =−.+y equals negative , 2.65 , x plus 25.
What does the x-intercept mean in terms of the situation?

Answers

Answer:

Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

math problem: Amanda worked 4.5 hours on Tuesday and 5.2 on Thursday. Her pay rate is $10.50 per hour. How much will Amanda get paid for the two days?

Answers

Answer:

$101.85

Step-by-step explanation:

Think of the two days as separate equations. They are added together to get a sum of the pay she will receive after the two days.

Equation

(4.5*10.5) + (5.2*10.5) = x (This just represents the unknown value)

Solve Through

(47.25) + (54.60) = x

47.25 + 54.60 = x

101.85 = x

Amanda will get paid $101.85 For her 2 days of work.

The equation has no solution (C)

Step-by-step explanation:

You just solve the problem, and at the end it says 0=32 which is false, therefore it has no solution. So, the person probably added another x to the equation, or instead of saying that it didn't equal anything they thought it meant it equalled 32.

At the start of the month, the value of Susan’s checking account was $53. She gets paid $375 per week for 4 weeks and spends $172 on groceries for the month. How much does Susan have in her checking account at the end of the month?

Answers

$1,381

Because 375×4= 1,500
and 1,500-172= 1,328
lastly, 1,328 + 53= 1,381
Susan has $1381.

Answers

i’m pretty sure it’s a and c
It has to be A and C

Can someone please give me an answer.

Answers

It is not A. It’s B!
The reason it’s B is because when you look at the table, the y- intercept (or where it’s at when it’s at 0) is -75.
So you know it’s
Y= (something) -75
When you look at the rest of the table you can see that for every five it’s going up on the left side, it’s going up 25 on the right side.
If you divide 25 by 5 to figure out how much it is going up per 1 time instead of 5, you will get 5. You have to add X to that because that is the slope or how much you are going up by.
That means your equation is...
y=5x-75, or B!
Hopefully that helps you!

The answer is y=5x-75 or B
