Answer:

x = -16 $\frac{2}{3}$

Step-by-step explanation:

When there are two lines that intersect at one point, the two angles that are directly opposite each other are equal. So in this case, (6x+175) = (3x + 127)

6x + 175 = 3x + 125

6x - 3x = 125 - 175

3x = -50

x = -50 ÷ 3

x = -16 $\frac{2}{3}$

3x + 127 = 6x + 175 (Since its an opposite angle)

3x = 48

x = 16

Ahat [919]

Answer: $58,088.57

Step-by-step explanation:

The investment is compounded weekly so you need to change the parameters of the equation to a weekly figure:

Interest rate is yearly so:

= 3.75%/52

= 3.75/52% per week

Number of periods is 4 years so:

= 4 * 52

= 208 weeks

Future value in 4 years is:

= 50,000 * ( 1 + 3.75/52%)²⁰⁸

= $58,088.57

HELPPPPPPPPP PLEASE!!! :(

Answer:

x = 25

Step-by-step explanation:

Given:

∠A = ∠B (Vertically opposite angles)
∠A = (7x - 8)°
∠B = (6x + 17)°

Since ∠A is equivalent to ∠B...

$\implies (7x - 8)= (6x + 17)$

Open the parenthesis:

$\implies 7x - 8= 6x + 17$

Add 8 both sides:

$\implies 7x - 8 + 8= 6x + 17 + 8$

Simplify both sides:

$\implies 7x = 6x + 25$

Subtract 6x both sides:

$\implies 7x - 6x = 6x - 6x + 25$

Simplify both sides:

$\implies x = 25$

Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
