Hi! I'm happy to help!
Point slope form states that y-[tex]y_{1}[/tex]=m(x-[tex]x_{1}[/tex]). m represents your slope (rise/run) and [tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent your first y and x points, and y and x represent your second y and x points. We already have our equation here:
y - 4 = 1/4(x- 8)
Now, let's dive into what slope-intercept form is. Slope intercept form states that y=mx+b. m represents our slope, b represents our y intercept, y represents a y point, and x represents the corresponding x point.
Since we know our m, we can solve for b, by using our other numbers. Let's use our first set of coordinates.
4=1/4(8)+b
4=2+b
2=b
Now our second set to double check:
2=1/4(0)+b
2=0+b
2=b
We know that b must equal 2, so our equation must be y=1/4x+2, which is option 3.
You should pick option 3.
(y-intercept is where the line hits the y-axis(when x=0). We could've used our second coordinates (0,2), where x equals 0 to know that 2 is the y-intercept (b). This shortcut only works on specific problems though.)
I hope this was helpful, keep learning! :D

Write the equation of the line in fully simplified slope-intercept form.
Answer:
[tex]y=-6x+2[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
1) Determine the slope (m)
[tex]m=\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Given the graph, we determine which points we could use. For example, we could use the two points [tex](0,2)[/tex] and [tex](1,-4)[/tex]:
[tex]m=\displaystyle \frac{-4-2}{1-0}\\\\m=\displaystyle \frac{-6}{1}\\\\m=-6[/tex]
Therefore, the slope of the line is -6. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-6x+b[/tex]
2) Determine the y-intercept (b)
Recall that the y-intercept occurs when x=0. Given the point (0,2), we know that the y-intercept is 2. Plug this into [tex]y=-6x+b[/tex]:
[tex]y=-6x+2[/tex]

Cavenger of 92 miles in 2 2/3 hours if he drove a constant rate how far did he travel in one hour enter your answer as a whole number proper fraction or mixed number in simplest form
Answer:
34 1/2 miles
Step-by-step explanation:
92 miles = 2 2/3 hours
x miles = 1 hour
92 ÷ 2 2/3 = 34.5
34.5 x 1 = 34.5
34.5 miles = 1 hour

write the expression as the sine or cosine of an angle.
sin 3x cos x - cos 3x sin x
In other words, you'll type "sin" without quotes in the green box.
Also, you'll type "2" in the gray box, which also won't have quotes.
===========================================================
Explanation:
We'll use the first hint. Note the pattern of sin cos +- cos sin which matches (somewhat) with the original expression.
Specifically, we'll use this identity
sin(A - B) = sin(A)cos(B) - cos(A)sin(B)
In this case, A = 3x and B = x
So,
sin(A - B) = sin(A)cos(B) - cos(A)sin(B)
sin(A)cos(B) - cos(A)sin(B) = sin(A - B)
sin(3x)cos(x) - cos(3x)sin(x) = sin(3x - x)
sin(3x)cos(x) - cos(3x)sin(x) = sin(2x)
Olivia bought snacks for her team's practice. She bought a bag of popcorn for $3.39
and a 4-pack of juice bottles. The total cost before tax was $7.43. Which tape diagram
could be used to represent the context if x represents how much each bottle of juice
costs?
The required diagram could be used to represent the context if x represents how much each bottle of juice cost is D. Option D is correct.
Given that,
She bought a bag of popcorn for $3.39 and a 4-pack of juice bottles. The total cost before tax was $7.43.
To determine the diagram could be used to represent the context if x represents how much each bottle of juice costs.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the cost of each juice bottle be x.
Now,
accoding to the question,
4x = 7.43 - 3.39
Thus, the required diagram could be used to represent the context if x represents how much each bottle of juice cost is D. Option D is correct.

Step-by-step explanation:
Final grades are often computed using weighted averages. Some college professors use complicated weighted averages. The college professor tells you he will give you a 33% to 67% split on grades between tests and homework where which ever average is higher will be the 67%. What was your final grade be if your homework average is 52 and your test average is 71?
Using weighed mean, it is found that the final grade is 64.73.
--------------------------
To find the weighed average, we multiply each grade by it's weight.
--------------------------
Since we want to find the weighed average, we have to identify in the text the grades, and it's respective weighs.
Grade of 71, with a weight of 67%(as it states in the text, the higher grade has a weight of 67%).Grade of 52, with a weight of 33%(as it states in the text, the lower grade has a weight of 33%).Thus, the final grade is:
[tex]F = 71\times0.67 + 52\times0.33 = 64.73[/tex]
The final grade was of 64.73.

"You are growing like a weed!” D’rek's grandmother said to him when she saw him for the
first time in a year. If D’rek grew 8 inches over the last year, and an average dandelion (a
common weed) grows 0.1 inches in one day, is D’rek growing like a weed? Justify your
answer.
growth rate:
[tex]=\frac{8}{365}[/tex]Derek is not growing like a weed because the weed grows at 0.1 inch per day, while he grows at a rate of 0.022 inch per day.
The number of days in a year = 365
The question says that D'rek grew at the rate of 8 inches in the last year'
D'reks growth rate:
[tex]=\frac{8}{365}[/tex]
= 0.022 inch per day
From the calculation above, Derek is growing at the rate of 0.022 inch per day. But the question says that the weed grows at the rate of 0.1 inch per day
In conclusion, Derek is not growing like a weed, his growth rate differs from that of the weed.

A car at a red light accelerates for 5 seconds and is now travelling 25 m/s. What was the car’s acceleration?
Answer:
5 m/s²
Step-by-step explanation:
t (time) = 5 s
u (initial velocity) = 0m/s
v (final velocity) = 25m/s
a = (v-u)/t
a = (25-0)/5
a = 25/5
a = 5 m/s²

Slove 3(t-3)=5(2t-1)
Answer:
t = 7/-4 OR -1 3/4
Step-by-step explanation:
3(t - 3) = 5(2t - 1)
3t - 9 = 10t - 5
(3t - 3t) - 9 = (10t - 3t) - 5
-9 = 7t - 5
-9 + 5 = 7t (- 5 + 5)
-4 = 7t
-4/-4 = 7t/-4
t = 7/-4 OR -1 3/4

a right triangle has a non hypotenuse side length of 45" and the hypotenuse measures 53". What is the length of the other non-hypotenuse side?
Answer:
28"
Step-by-step explanation:
the length of the other non-hypotenuse side =
√(53² - 45²) =√(2809-2025) =√784 = 28"

Answer:
The car will use 20 liters of gas
Step-by-step explanation:
160KM/8L = 20KM per liter
