Answer:
-8
Step-by-step explanation:
We can use the formula [ y2-y1/x2-x1 ] to solve.
-4-4/2-1
-8/1
-8
Best of Luck!
First of all, Let's find the slope because we need it on the formula for finding the y-intercept.
m = y2 - y1 / x2 - x1
From the points given in the question,
x1 = 1
x2 = 2
y1 = 4
y2 = -4
Plugging in the above formula,
➝ m = -4 - 4 / 2 - 1
➝ m = -8 / 1
➝ m = -8
Now finding the y-intercept[tex]:[/tex]
➝ y = mx + b
And if we put in the values from our first point (1, 4) we get
➝ 1 = -8 (4) + b
➝ 1 = -32 + b
➝ b = 1 + 32
➝ b = 33
Required equation of the line:
➝ y = -8x + 33

Answer:
y=3x+18
Step-by-step explanation:
Since slope-intercept form is y=mx+b, we first need to find the slope.
m=y2-y1/x2-x1
m=0-(-9)/-6-(-9)
m=9/3=3
Next we need to find b, or the y-intercept
to do that we plug in numbers to what we already have.
y=3x+b
0=-18+b
b=18
Now we put it all together.

Answer:
cosine = adjacent / hypotenuse
cosine 62º = JL / 17
JL = cosine 62º * 17
JL = .47 * 17
JL = 7.99
JL = 8.0
Step-by-step explanation:
Write an equation in slope intercept form for the line that passes through (2,-2) and is parallel to y=-5/2x+5
[tex]y=mx+b\\y=x-2[/tex]
Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.
Find if both graphs are parallel, that means the equation must be false.
[tex]x-2=-\frac{5}{2}x+5[/tex]
Multiply whole equation by 2 to get rid of the fractional 2.
[tex]2x-(2)(2)=-\frac{5}{2}(2)(x)+5(2)\\ 2x-4=-5x+10\\2x-4+5x-10=0\\7x-14=0\\7x=14\\x=2[/tex]
Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5

$0.55
$1.30
$2.65
$5.30
Answer:
$5.30
Step-by-step explanation:
Convert 20% to it's decimal form.
20%/100 = .20
Multiply .20 with 26.50.
.2 x 26.5 = 5.3

· Josh Duchene worked at three jobs in three weeks. In the first week, he earned $360. In the next week, he
was paid $345. In the third week, he was paid $315. What average pay per week did Josh earn for these
three weeks?
The average pay per week Josh earned for three weeks is $340.
What is an average?The term average is the sum of all the numbers divided by the total number of values in the set.
Now it is given that,
Pay received in first week = $360
Pay received in second week = $345
Pay received in third week = $315
So,
Total money earned in three weeks = $360+$345+$315
= $1,020
Now number of weeks = 3
therefore, average pay per week = Total money earned in three weeks/number of weeks
⇒ average pay per week = $1020/3
⇒ average pay per week = $340
Thus, the average pay per week Josh earned for three weeks is $340.
