The range of a function is the value of y where it is defined
 Note the coordinates of the 3 points:

A(-2,0)
B(2,4)
C(3,-3)
As described the range (values of y) are 0,4 & -3
Hence Range ={ y ∈ -3 ≤ y ≤ 4}

What is an equation in point-slope form of the line that passes through (-7,1) and (-3, 9)
Inga [223]

Step-by-step explanation:

let eqn be y - y1 = m(x - x1)

m = (9 - 1)/(-3 - (-7))

m = 2

sub (-7, 1):

y - 1 = 2(x + 7)

therefore, the equation is y - 1 = 2(x + 7)

If KLMN is a parallelogram and<br> m∠K = 110°, then what is m∠L?
dlinn [17]

Answer:

70 degrees

Step-by-step explanation:

In the parallelogram  KLMN, the sum of the adjacent angle is 180 degrees

Hence;

m<K + m<L = 180

110 + m<L = 180

m<L = 180-110

m<L = 70degrees

Hence the measure of m<l is 70 degrees

which expression is equal to 2 square root of 28 - 5 the square root of 63? a. -11 square root of 7, b. -37 the square root of 7
adell [148]

Answer:

<u>The correct answer is A. - 11 square root of 7.</u>

Step-by-step explanation:

We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.

Let's simplify it:

2 √28 - 5 √ 63

2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)

2 * 2 √7  - 5 * 3 √ 7

4 √7 - 15 √7

- 11 √7

<u>The equal expression is A. - 11 square root of 7.</u>
