What is the value of the expression 18 - 8 X 2 + 20 / 7? 10 13 7 39

1 answer:

8 0

Unless you are missing parenthesis it something, With the order of operation, you would multiply 8 and 2 first, and divide 20 by 7, to get 18-16+2.857242, now add and subtract, you get 4.857242

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (6, 2)

Point (9, 8)

Step 2: Find slope m

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

Substitute in points [Slope Formula]: $\displaystyle m=\frac{8-2}{9-6}$
[Fraction] Subtract: $\displaystyle m=\frac{6}{3}$
[Fraction] Divide: $\displaystyle m=2$

24. Use the intercepts to graph the equation.

romanna [79]

Answer:

See below ~

Step-by-step explanation:

Finding x-intercept

Take y = 0
2x - 5(0) = 10
2x = 10
x = 5
x-intercept is at (5, 0)

Finding y-intercept

Take x = 0
2(0) - 5y = 10
-5y = 10
y = -2
y-intercept is at (0, -2)

32x - 4 = 4x2 + 60 For the equation shown, choose the description of the solutions.

Furkat [3]

All to one side:

4x^2-32x+64 = 0,

divide by 4:

x^2 -8x + 16 = 0

apply formula or see that it is (x-4)^2!, so only x =4 is a root and it is double.

Find the length of the major arc in RED. Round your answers to the nearest tenth.

scoray [572]

Answer:

52.4

Step-by-step explanation:

Arc length = 2πr(θ/360)

r = 10

θ = 300°

Arc length = 2π(10)(300/360) = 20π(0.8333) = 16.666π ≈ 52.36
