Answer 1

Answer:

See explanation

Step-by-step explanation:

The importance of the inequality is that this it restricts the possible values of the change.

Without the inequality, q would not be restricted at all, and would be free to range in all values.

Answer:

look below

Step-by-step explanation:

going left and right changes the x( first number in each parentheses)

going up and down changes the y (second number in parentheses)

going to the left by 9 means all the first numbers are going in the negative direction (-9)

going up by 12 means the second numbers are going in the positive direction (+12)

take all x values and add -9, take all y values and add 12

X (-15, 13)

Y(-5,12)

Z(-8, 15)

it would be 7,6 5,9 7,8

what is the slope?

Answers

Answer:

2/3

Step-by-step explanation:

Find a two coordinates on the line such as (20,40) and (50,60)

plug it into the slope formula m= y2 - y1 / x2- x1

it doesn't matter what way you plug them in

m = slope

m = 60-40 / 50 - 20 = 20/30 = 2/3

The slope is 2/3 I simplified 20/30 by dividing by 10

Solve the inequality for x
12x>9(2x-3)-15

Answers

Step-by-step explanation:

12x > 9(2x - 3) - 15

12x > 18x - 27 - 15

12x > 18x - 42

42 > 6x

7 > x

so, this is true for all values < 7

so, x is in (-infinity, 7)

both ends but included - therefore the round brackets.

What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?

Answers

Answer:

Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)

Step-by-step explanation:

All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

Angle L= angle E=> 5y+6=111
5y=105
Y=21

MN = FG
5x+2=12
5x=10
X=2

The other person didn’t give x and y so I will:
5x + 2 = 12. This is because if we rotate the quadrilateral those two are equivalent.
Minus 2 from both sides
5x = 10
Divide by 5
X=2

5y+6 = 111
Minus 6 from both sides
5y = 105
Divide by 5 from both sides
Y=21

Answer:

x=24°

Step-by-step explanation:

(3x-6)°+x°= 90°

4x=90+6

4x= 96°

x= 24°

Answer:

Step-by-step explanation:

(3x-6)°+x°=90°

First, combine like terms:

3x°+x°-6°=90°

4x°-6°=90°

Add 6° to both sides:

4x°=96°

Divide 4 from both sides to isolate x:

x=24°

Check your answer:

3(24)-6+(24)=90°

72-6+24=90°

66+24=90°

90°=90° (correct)
