For The Pairs Below Put Each Question In Slope Intercept Form And Whether The Graphs Of The Line Will

Answers

Answer 1
3: rearrange the 2nd equation so y is isolated, add 3x to both sides
Both equations are now y = 3x + 2. So they are identical, and therefore have infinite solutions since solution means how many times do these lines meet/overlap.

4: rewrite left-right and the equations are now:
y = -x
y = -x -2
Same slope but different intercept (b value), so they are parallel and NEVER meet (NO SOLUTIONS)

5. Rearrange:
y = -x + 4
y = x + 4

So they have different SLOPES in this example (m value). This means they are not parallel or identical, so they can only cross once (one solution)

6: rearrange both
y = 3x - 1
y = 3x + 1
Same slope (m=3), different intercepts (b= 1 and -1). Same slope means parallel, different b means different intercepts so they are NOT identical. Since parallel lines can not cross, there are no solutions

7: y = 2x + 4
y = 2x - 4
Same slope (m=2), different b values (y-intercepts are 4 and -4), so parallel but not identical, no solution

Do your elderly neighbor’s housework 15% of your time, and earn $16.00 an hour. What will your average hourly wage be? Enter your answer up to two decimal places.

Answers

Answer:

13.75

Step-by-step explanation:

The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):

(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.

Now how did I find the translation rule ( x - 1, y + 4). Well basically, I did was

8 - 9 = -1

-4 - (-8) = 4

Now if you use the same translation rule for (9, -8), you will get :-

(x - 1, y + 4)

( 9 - 1, -8 + 4)

( 8, -4)

I get the same answer that is given in the problem.

Answer:

  1. 2x +2y = 310; x -y = 55

  2. y = 50, x = 105

Step-by-step explanation:

Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...

  2x + 2y = 310

The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...

  x - y = 55

__

We can divide the first equation by 2, and subtract the second.

  1/2(2x +2y) -(x -y) = 1/2(310) -(55)

  2y = 100 . . . . . . . simplify

  y = 50 . . . . . . . . . divide by 2

  x -50 = 55   ⇒   x = 105 . . . . use the second equation to find x

The two numbers are 105 and 55.

Answer: C. [tex]4(\dfrac13g-3)[/tex]

Step-by-step explanation:

Given: Robin braided g inches of a friendship bracelet.

Number of inches braided by Olivia = [tex]\dfrac13g-12[/tex]

The total number of inches braided by Robin and Olivia = Number of inches braided by  Robin + Number of inches braided by Olivia

[tex]=g+\dfrac13g-12\\\\=\dfrac43g-12\\\\\=4(\dfrac13g-3)[/tex]

The total number of inches braided by Robin and Olivia = [tex]4(\dfrac13g-3)[/tex]

Find the area of a square that has a side length of 4.8 cm.

Answers

A=23.04cm² , A=a2=4.82=23.04cm²

Answer: 23.04 cm.

Step-by-step explanation:

To find the area of something, we use the equation l x w, or length x width.

A square has 4 sides, and all 4 sides are equal. If the length of a square is 4.8, then the width is also 4.8 since all 4 sides of a square are equal.

Since we're using the equation l x w to find the area of the square, we have to multiply 4.8 x 4.8.

4.8 x 4.8 = 23.04.

Therefore, the area of the square is 23.04 centimeters!
