(-8, -2) and (1, 9) find the slope
Answer:
11/9
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( 9 - -2)/(1 - -8)
= ( 9+2)/ (1+8)
= 11/9

HELP PLS IM BEGGING YOU PLS HELP, its due todayyy pls. Angle CBD is the only one i got right and the rest is wrong. I dont know how to answer it anymore.
Answer:
try It would be number 81
Step-by-step explanation:
Abc= 110
ceo=70
dbe=110 or 120
and abe= 60 70 or 81
Answer:
ABC=112 degrees
DBE=112 degrees
ABE=68 degrees
Step-by-step explanation:
CBD=ABE
ABE=68 degrees
First let's take these as X,
ABC=DBE=X(Vertically opposite angles)
ABC+DBE+CBD+ABE=360(angles around a point)
x + x +68 +68 =360
2x +136 =360
2x =360-136
2x = 224
x =112 degrees
therefore;
ABC=112 degrees
DBE=112 degrees

612.885089 --> 612.89 --> 612.9 --> 613
Solve the following equation.
X - (-6) = 15
Answer: x=9
Step-by-step explanation:
x-(-6)=15
first the subtraction sign and the negative sign becomes a plus sign
x+6=15
-6 -6
Next you subtract 6 from both sides of the equation. And that leaves you with
x=9

What is the quotient of 7.584 x 10^9 and 7.9 x 10^ 2 expressed in scientific notation?
Answer:
9.6 × 10 6
Step-by-step explanation:
(7.584 × ) ÷ (7.9 × 10²)
This gives;
× = 0.96 ×
Simplifying further gives;
9.6 × = 9.6 ×
solve for y
-10x + 2y =4
Answer:
y = 5x + 2
Step-by-step explanation:
Add 10x to both sides
2y = 10x + 4
Divide both sides by 2
y = 5x + 2

-3(4x+3)+4(6x+1)43
please solve the problem fully
Answer and Step-by-step explanation:
First, distribute the numbers outside of the parenthesis to the numbers on the inside.
-12x - 9 + 24x + 4 = 43
Combine like terms.
12x - 5 = 43
Add 5 to both sides.
12x = 48
Divide by 12 on both sides of the equation.
x = 3 <- This is the answer.

A worker earns the same amount for each
hour. If he earned $48.00 in 3 hours, how
much would he earn in 8? In 40?
Answer: 8 hours= $128 40 hours= $640
Step-by-step explanation:
$48.00 divided by 3 = $16.00 an hour. so 16x8=128 and 16x40=640
Using rational numbers how do you solve -37 + (-64)
Answer:
-101
Step-by-step explanation:
An addition sign in front of the negative number means to subtract that number.
Another way to write -37 + (-64) is:
-37 - 64
-37 - 64 = -101

Write an equation in slope-intercept form for the line with slope -3/2 and y -intercept -3
Answer:
It is
[tex]{ \underline{ \sf{y = - \frac{3}{2}x - 3 }}}[/tex]
Step-by-step explanation:
General equation:
[tex]{ \sf{y = mx + c}}[/tex]
m is the slope
c is the y-intercept

If a function is defined by the equation y = 1/2x -3/2 , which equation defines the inverse of this function?
Answer:
B
Step-by-step explanation:
Rearrange the equation making x the subject
y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{2}[/tex] ( multiply through by 2 to clear the fractions )
2y = x - 3 ( add 3 to both sides )
2y + 3 = x
Change y back into terms of x with x being the inverse function, that is
y = 2x + 3 → B
a line passes through the points 3, 0 and 4, 1. what is the y-intercept of the line
9514 1404 393
Answer:
(0, -3)
Step-by-step explanation:
The slope is the same for any segment of the line. The slope from (0, y) to (3, 0) is the same as from (4, 1) to (3, 0).
Δy/Δx = (y -0)/(0 -3) = (1 -0)/(4 -3)
y = -3(1/1) = -3 . . . . . multiply by -3
The y-intercept is (0, -3).
what passes through the points (-1/2 4) and (1/2 6). show your work
Step-by-step explanation:
The equation of line which passes through these points is determined by:
p(x1,y1)=(-1/2,4) p(x2,y2)=(1/2,6)
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} \\ \frac{y - 4}{6 - 4} = \frac{x + \frac{ 1}{2} }{ \frac{1}{2} + \frac{1}{2} } \\ \frac{y - 4}{2} = \frac{2x + 1}{2} \\ 2(2x + 1) = 2(y - 4) \\ 4x + 2 = 2y - 8 \\ 4x - 2y + 2 + 8 = 0 \\ 4x - 2y + 10 = 0[/tex]
