Answer:

m = 4

Step-by-step explanation:

In order for this equation to be true, the angles must be complementary.

So, 18m- 12 + 7m + 2 = 90

25m - 10 = 90

25m = 100

m = 4

Question 1 (3 points) What value of p makes this equation true? 3p - 8 = -23 . O p = -6 Op = -5 Op = 5 p = 6​
olchik [2.2K]

The value of p that makes the given equation true is equal to: B. p = -5

<u>Given the following equation:</u>

  • 3p - 8 = -23

To find a value of p that makes the given equation true:

In this exercise, you're required to determine a value of p that satisfies the given equation true such that when substituted into the equation, it has a true result or outcome.

Rearranging the equation by collecting like terms, we have:

3p - 8 = -23\\\\3p=-23+8\\\\3p=-15\\\\p=\frac{-15}{3}

p = -5

Prepare an amortization schedule for a three-year loan of $57,000. The interest rate is 8 percent per year, and the loan calls f
BartSMP [9]

To repay this loan in three years we must make annual payments of $23,560.

<h3>How to calculate how much we should pay annually?</h3>

To calculate the payments that we must make each year, taking into account the 8% interest, we must carry out the following operations:

  • $57,000 ÷ 3 = 19,000

To calculate the interest equivalent to 8%:

  • $57,000 ÷ 100 = $570
  • $570 × 8% = $4,560

So, to calculate the total per year that we must pay, we must add both values:

  • $19,000 + $4,560 = $23,560

Finally, to know how much we pay in total for the interest on the loan, we multiply the value of the interest by the years that the loan lasted:

$4,560 × 3 = $13,680

If you factor y^2-81 COMPLETELY, would it just be (y-9)(y+9), or would it be something like y(3)(-3)y(3)(3)?
Vladimir79 [104]
That would be (y - 9)(y +9). When two binomials are multiplied, the distributive property is applied. However, if the equation is <span>y(3)(-3)y(3)(3), you just simply multiply them altogether. That would be -81y^2, which is not equivalent with y^2 - 81.</span>
