Hey there!

The answers here are given in a really, really useful formula called point-slope form. It's exactly what it sounds like- you need a point on the line and the slope to write the formula, and from there you can convert it to slope intercept or standard forms.

It's written in this form:

y - y1 = m(x-x1)

Where m means the slope and y1 is the y value and x1 is the x value of the point. You keep the x and y there. That means, with a point of (3, 10) and a slope of 2, we have:

y - 10 = 2(x - 3)

Your answer is B :)

Hope this helps!

Step-by-step explanation:

use bodmas

start with multiplication

-4*10 = -40

5+5/2 - 40

addition next

5 + 5/2 = 7.5

7.5 - 40 = -32.5

Please explain how you got your answer because i cant grasp this :/

Triss [41]

Answer:

390.4 in.²

Step-by-step explanation:

Area of sector = πr² x θ/360
Area = 22/7 x 64 x 70/360
Area = 11 x 10 x 32 x 1/9
Area = 320 x 11/9
Area = 320 x 1.22
Area = 390.4 in.²

A-b

Lynna [10]

Answer:

$\boxed{\sf d. \ \frac{a}{b} = \frac{10}{7}}$

Step-by-step explanation:

$\sf \implies \dfrac{a - b}{b} = \dfrac{3}{7} \\ \\ \sf \implies \frac{a}{b} - \frac{b}{b} = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 + 1 = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + \frac{7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{3 + 7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{10}{7}$

Consider each equation. is it the equation of the line that is parallel or perpendicular to y=3x+2? Select yes or no for a-c

Mkey [24]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 is in this form with slope m = 3

• Parallel lines have equal slope

• The slopes of perpendicular lines are negative reciprocals of each other

y = - $\frac{1}{3}$ x - 8 has slope m = - $\frac{1}{3}$

3 and - $\frac{1}{3}$ are negative reciprocals

This line is perpendicular to y = 3x + 2

y = 3x - 10 has slope m = 3

This line is parallel to y = 3x + 2

y = 2x + 4 has slope m = 2

This line is neither parallel nor perpendicular to y = 3x + 2
