When you have a linear equation of the form y = mx, such as this one, you know immediately that the line passes thru the origin (0,0).  Were the form y = mx + b, then the y-intercept would be (0,b) and the x-intercept ( [-b/m, 0).

HEy, CAn YOu HElp ? :) Plssss (picture below) solve for #5
alexira [117]

Answer: a=60°, b=25°, c=95°,d=60°, e=25°, f=95°, g=60, h=35°

Step-by-step explanation:

a=60°, Because the angle opposite to it is 60°

b=25°, Because if you take 180°-155°, you get 25°

c=95°, Because if you add angles a and b, you get 85°, then you do 180°-85°=95°

d=60°, Because the angle opposite to it does

f=95°, Because angle c, which is opposite to it equals 95°

g=60°, Because if you add angles e and f, you get 85°, then you take 180°-85=95°

h=35°, Because if you add angles c and d, which is 155°, you take 180°-155=35°

Explain how to use the regression calculator to make a reasonable prediction.
Naddika [18.5K]

Given bivariate data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.

MATH - VOLUME OF FIGURE
Allushta [10]

Answer:

to find the volume of a cylinder

V=π x r^2 x h

now since we want the whole figure were going to add up the two heights to get one height number 4ft + 5ft = 9ft

V= 3.14 x 3^2ft x 9ft

V= 3.14 x 9ft^2 x 9ft

V= 254.34

Find the equation of a line that passes through the point (-2,1) and has a gradient of -3.
zavuch27 [327]

A straight line passing through the point (-2,1) and having a gradient of -3 yields the equation y = -3x - 5.

We know that a straight line is an infinitely long line with no curves on it. A straight line's equation is

y = mx + c...(1), where m is the gradient of the straight line and c is a constant.

Given that the gradient of the given straight line = m = -3.

Putting this value in (1), we get

y = -3x + c ...(2)

Again, the given straight line passes through the point (-2,1). So, we can put x = -2 and y = 1 to get the value of the constant c.

So, 1 = (-3)(-2) + c

i.e. 6 + c = 1

i.e. c = 1 - 6 = -5

(2) can be written as

y = -3x - 5

Therefore the equation of the given straight line is

y = -3x - 5
