Answer:

x = 5

Step-by-step explanation:

3x – 4y = 31

y = -2x + 6

Plug in Y

3x – 4(-2x + 6) = 31

Distribute

3x +8x-24= 31

Add like terms

11x - 24 = 31

Add 24 on both sides

11x = 55

Divide both sides by 11

x = 5

Answer:

(sqrt(7))/3 or decimal 0.8819171036881968635005385845464201419034197276941500601227781530...

Step-by-step explanation:

Simplify the following:

(sqrt(14))/(sqrt(18))

Hint: | Simplify radicals.

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

(sqrt(14))/(3 sqrt(2))

Hint: | Multiply numerator and denominator of (sqrt(14))/(3 sqrt(2)) by sqrt(2).

Rationalize the denominator. (sqrt(14))/(3 sqrt(2)) = (sqrt(14))/(3 sqrt(2))×(sqrt(2))/(sqrt(2)) = (sqrt(14) sqrt(2))/(3×2):

(sqrt(14) sqrt(2))/(3×2)

Hint: | Multiply 3 and 2 together.

3×2 = 6:

(sqrt(14) sqrt(2))/6

Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(14) sqrt(2).

sqrt(14) sqrt(2) = sqrt(14×2):

(sqrt(14×2))/6

Hint: | Multiply 14 and 2 together.

14×2 = 28:

(sqrt(28))/6

Hint: | Simplify radicals.

sqrt(28) = sqrt(2^2×7) = 2 sqrt(7):

(2 sqrt(7))/6

Hint: | In (2 sqrt(7))/6, divide 6 in the denominator by 2 in the numerator.

2/6 = 2/(2×3) = 1/3:

Answer:  (sqrt(7))/3

Answer:

y = 1/3x + 4/3

Answer:

Step-by-step explanation:

(1, -16) (2, -7)

(-7 + 16)/(2 - 1) = 9/1= 9

y + 16 = 9(x - 1)

y + 16 = 9x - 9

y = 9x - 25

Answer:

z = [tex]\sqrt{117}[/tex]

Step-by-step explanation:

find 'y' first by using the altitude rule:

y/4 = 9/y

cross-multiply:

y² = 4(9)

y² = 36

y = [tex]\sqrt{36}[/tex] = 6

Find 'z' by using the Pythagorean Theorem with legs equal to 6 and 9

6² + 9² = z²

36 + 81 = z²

117 = z²

z = [tex]\sqrt{117}[/tex]

Answer:

12(m +1) > 18m - 3

12m + 12 > 18m - 3

12+3 > 18m - 12m

15 > 6 m.

m < 15/6

m < 2.5

4th option is correct.

Answer:

{m| m < 2.5}

Step-by-step explanation:

m < 2 1/2,m < 2.5 , m ∑ [-∞, 5/2]

Answer:

Step-by-step explanation:

When you know the slope m of a line and a point (x₀,y₀) on the line, you can write an equation for the line in "point-slope" form:

y-y₀ = m(x-x₀)

In your case,

y+2 = -3(x-6)

The line is easier to graph if you rearrange the equation to solve for y:

y = -3x+16

You know that (0,16) is one of the points on the line.

Plot the two points that you know, (6,-2) and (0,16), then draw a line through them.

Answer:

c

Step-by-step explanation:

The expression that shows the change in Miguel's account balance is -20×4. Thus, option (C) is correct.

Given, Miguel withdrew $20 per week from his bank account for 4 weeks.

Since he withdrew money, the change in his account balance would be negative.

The expression -20 represents the amount he withdrew each week, and the -4 represents the number of weeks.

Multiplying 4 with the initial balance of -20 gives us the change in his account balance.

Therefore, the expression -20×4 correctly represents the change in Miguel's account balance.
