Hatshy [7]

Answer:

The unit rate\frac{4}{1} of the graph is 4, the slope of the graph is 4, and the comparison between answers is that they are equal.

Step-by-step explanation:

For every increase of 1 in the X value of the graph, the Y value increases by 4, so the slope would be \frac{4}{1} or 4.

Brian's gross earnings for the week of July 8, 2019, are $1227.38. His deductions comprise 23% of his total compensation.
Sindrei [870]

Answer:

$945.08

Step-by-step explanation:

Given: Gross earning of Brian= $1227.38

            Deduction= 23% of total compensation.

Now, finding the amount of deduction from Brian´s gross earning.

Amount of deduction= \frac{23}{100} \times 1227.38

∴ Amount of deduction= \$ 282.2974

Next, finding the net pay of Brian after deduction.

Net pay= Gross\ pay - deduction

Net pay= 1227.38 - 282.2974

∴ Net Pay= \$ 945.0826 \approx \$945.08

Hence, Brian´s net pay is $945.08

Fred can paint a house in 10 hours. Together, pat and Fred can paint a house in 8 hours. Which equation, when solved will produc
sattari [20]

Answer:

Pat t2 = 40 hrs

Step-by-step explanation:

Given:-

- Fred can paint a house in t1 = 10 hours.

- Pat can paint a house in t2 hours.

- pat and Fred can paint a house in T = 8 hours.

Find:-

Which equation, when solved will produce the number of hours need for pat to paint the house alone

Solution:-

- The number of people working on a particular activity " painting a house " is inversely proportional to time taken to complete the activity. tn = T. The relation for individual time taken ti to complete an activity.

                              Sum ( 1 / ti ) = 1 / T

Where, ti = The individual time for (ith) person

            T = The total time taken to complete the time by i = n number of people.

- For n = 2,

                              1/t1 + 1/t2 = 1/T

                              1/10 + 1/t2 = 1/8

                              1 / t2 = 0.025

                              t2 = 40 hrs

- It takes Pat t2 = 40 hrs to complete painting the house.

ONLY ANSWER IF YK IT ILL GIVE THE CORRECT ANSWER BRAINLIEST
Olin [163]

Answer:

  9 units

Step-by-step explanation:

If you assume the solution is an integer, then you are looking for factors of 27 that differ by 6. You don't have to look far:

  27 = 1×27 = 3×9

If the length is 9 units and the width is 3 units, the width is equal to the length minus 6 units.

The length is 9 units.

_____

<em>Alternate solutions</em>

You can write an equation for the area using L to represent the length. The area is the product of length and width, so is ...

  A = LW

  27 = L(L-6) = L^2 -6L

You can "complete the square" by adding the square of half the L coefficient:

  27 +3^2 = L^2 -6L +3^2

  36 = (L -3)^2 . . . . . simplify a bit

  6 = L -3 . . . . . . . . . positive square root

  9 = L . . . . . . . . . . . . add 3

The length is 9 units.

__

You can also put the quadratic equation into standard form:

  L^2 -6L -27 = 0

To factor this, you're looking for factors of -27 that have a sum of -6. From above, we know these are -9 and +3. So the factorization is ...

  (L -9)(L +3) = 0

The solutions are the values of L that make these factors be zero:

  L -9 = 0   ⇒   L = 9

  L +3 = 0   ⇒   L = -3

Only the positive solution is useful as a measure of length. The length is 9 units.

Factor completely 3x^2+2x-1
Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)
