Answer:
-81
Step-by-step explanation:
f(x) = 8x -1
f(-10) = 8(-10) -1
f(-10) = -80-1
f(-10) = -81
Aidan has $25. He plans to save $7 each week. How many weeks does he need to work in order to have saved $130? Enter an equation that models the situation with w, the number of weeks
Answer:
has 25, wants 130, so he needs to save (130-25)= 105.
105/7= 15 weeks
25+7w= 130

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x + 6
Step-by-step explanation:
Line is passing through the points (0, 6) & (1, 7)
So, y-intercept (b) = 6
Slope (m) [tex] =\frac{(7 - 6)}{(1 - 0)} = \frac {1}{1} = 1[/tex]
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging the values of m and b in the above equation, we find:
y = 1*x + 6
y = x + 6

.
y = 3x - 2
m=
b=
Answer:
m is 3 since it's the slope and b is -2 since its the y-intercept
Step-by-step explanation:
the formula is y=mx+b so 3 is in the m spot and -2 is in the b spot.
Answer: m = 3 , b = -2
Step-by-step explanation:
y = 3x - 2, we found out m and b by using the form y = mx + b, where m is the number in front of x.
Therefore we found out that m is 3, b is -2.

Answer:
y-9=7(x+5)
Step-by-step explanation:
Point-Slope form is
[tex]y-y_{1} =m(x-x_{1} )[/tex]
where m equals the slope of the line and y1 and x1 represent the y and x coordinates of one of the points on that line.
First, let's find the slope (change in y divided by the change in x):
[tex]\frac{9-(-5)}{-5-(-7)} =\frac{14}{2} =7[/tex]
Now, let's choose any one of the two points, I'll pick (-5,9), but (-7, -5) also works.
Substitute in the y value (in this case 9) for y1 and substitute the x value (in this case -5) for x1
We can also substitute the slope, m which we know is 7.
y-9=7(x-(-5)
y-9=7(x+5)

Find the least common multiple (LCM) of 28 and 63.
Answer:
252
Step-by-step explanation:
We can use the identity
LCM(a, b) = a * b / GCD(a, b)
GCD(28, 63) = GCD(4 * 7, 9 * 7) = 7
LCM(28, 63) = 28 * 63 / 7 = 28 * 9 = 252

Answer:
3: D - Undefined
4: A - 1
Step-by-step explanation:
For Question 3 your answer is D, undefined, because it does not have a slope, a slope is like a hill, but that just goes straight up, thus it is undefined.
For Question 4 your answer is A, 1, because it moves one digit to the right and then 1 digit up, Thus that is your answer.

Answer:
y-1=7(x-0)
Step-by-step explanation:
The line perpendicular to y=-1/7+1 is y=7+1 because you find the reciprocal of the slope.
Then find one point on the line since the equation has a y intercept just use (0,1) and put that into point slope

Answer: 78 square units
Step-by-step explanation:
Travis, Jessica, and Robin are collecting donations for the school band. Travis wants
to collect 20% more than Jessica, and Robin wants to collect 35% more than Travis.
If the students meet their goals and Travis collects $43, how much money did they collect
in all?
Answer:
their total collected is $135.45
Step-by-step explanation:
travis collect 20% more than Jessica
if travis collect $43 then
20% of 43
43 × 20 ÷ 100 = $8.6
Jessica collected $8.6 less than travis
$43 - $8.6 = $34.4
and Robin collect 35% more than travis
35% of 43
43 × 35 ÷ 100 = $15.05
therefore Robin collect $15.05 more than travis
$43 + $15.05 = $58.05
their total collected
Jessica collected $34.4
robin collected $58.05
travis collected $43
total
$34.4 + $58.05 + $43 = $135.45

What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (0, 3) and (4, 0).
The slope is the change in y over the change in x.
The first number in the parentheses is the x value, the second number is the y value.
Slope = (0-3) / (4-0)
Slope = -3/4
The y intercept is the y value when x is 0.
The given point (0,3) has x as 0, so the y intercept would be 3
Answers: slope = -3/4, y intercept = 3
Answer:
y intercept = 3 slope = -3/4
