Answer:

Step-by-step explanation:

Perpendicular lines are lines whose slopes are negative reciprocals of each other

To find the slope of the line we are given, we can rearrange the equation

$4x - 5y = 4\\4x - 4 = 5y\\y = \frac{4}{5}(x) - \frac{4}{5}$

The slope of this line is $\frac{4}{5}$ , so the slope of the other line is $\frac{-5}{4}$

next, we can use the given point to find the equation $y = mx +b$

we know m, we can solve for b

$y = \frac{-5}{4}(x) + b\\-3 = \frac{-5}{4}(-2) + b\\-3 = \frac{5}{2} + b\\\frac{-6}{2} = \frac{5}{2} + b\\$

$b = \frac{-11}{2}$

$so,\\y = \frac{-5}{4}(x) - \frac{11}{2}$

Imagine you are teaching a younger student how to factor. Describe in full sentences what you would say to teach the young stude

djyliett [7]

Answer:

$x^2+ 4x - 21$ =(x-3)(x+7)

Step-by-step explanation:

To factor the trimonial: $x^2+ 4x - 21$ , we follow these steps:

Step 1: Multiply the first and last term

$-21 \times x^2=-21x^2$

Step 2: List out product factors of the term derived above

$-21=-1 \times 21\\ -21=-3 \times 7\\-21=3 \times -7\\-21=1 \times -21$

Step 3: Determine which of the factors sum up to the middle term 4x

The required product is: -3 and 7

Therefore: -3x+7x=4x

Step 4: Replace the middle term by the expression derived in step 3 and factorize.

$x^2+ 7x -3x- 21\\=x(x+7)-3(x+7)\\=(x-3)(x+7)$

Which of the following is a coefficient in the algebra expression 12p^5+r-16?

Andru [333]

Answer:

12 (or A)

Step-by-step explanation:

A coefficient is the number before a variable.

Examples: 5r , 34y, 10x^2 (the coefficients are 5, 34, and 10)

12 has a variable after it, so 12 is a coefficient.
