Determine the slope of the line that passes through each pair of points. Write in simplest form. (3,8) and (1,5)
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.
If XY is 4 m and WZ is 9 m, the exact volume of the cone is ___π square meters.
Answer:
[tex] 48\pi \: {m}^{3} [/tex]
Step-by-step explanation:
Radius of the cone (r) = XY = 4 m
Height of the cone (h) = WZ = 9 m
[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ \cancel3} \pi {(4)}^{2}( \cancel9) \: \: \red{ \bold 3 }\\ \\= \pi \times 16 \times 3 \\ \\\purple {\bold {V_{cone} = 48\pi \: {m}^{3}}} [/tex]

Hey, can anyone help me with this homework answer?
Answer:
x=10
Step-by-step explanation:
Answer: 10
Step-by-step explanation: 7x-11=x-49
7x - 11 = x - 49 so add 11 to both sides 7x = x -60
Then 7x - x = 6 so 60/6= 10
which number is the closest approximate value for sqrt 105
Answer:
10.
Step-by-step explanation:
Lets define a square root. A square root is a number multiplied by itself. 10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone. He heard a crack, but luckily it wasn't his iPhone 11. It was his spinal cord.
Compare the price between the iPhone 11 and spinal cord repairence.
(This question was on a question in math and it's kinda funny XD)
Answer:
The difference between iPhone 11 and Spinal cord repairence is 99,300$.
Step-by-step explanation:
To be honest, this is a really weird question. But a spinal cord injury can cost up to 100,000$ a year. And an iPhone 11 cost around 700$. It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol. And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
will give brainliest! number 4 it’s the pythagorean theorem
Which would be the first step for solving the equation x + 2 = 18?
A. add - 2 to both sides of the equation
B. add 18 to both sides of the equation
c.
divide both sides of the equation by
7
16
D
multiply both sides of the equation by
7
Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

How many roots does y=3x^2+8 have?
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)

Triangle congruence and similarity. PICTURE INCLUDED* SAS, SSS, ASA, or AAS
Answer:
Yes. SSS
Step-by-step explanation:
The dilation factor is to multiply by 3, from the smaller to larger triangle. This proves they are similar.
AA is not an accurate postulate.
Someone help, I don't understand what trig ratio to use, or how to get the answer to w or x
Answer:
Uhm I think you need to like times the 10 to the 56? erm yeaaaaaaa SOrry if you get it wrong
Step-by-step explanation:
Answer:
1:2
Step-by-step explanation:
56*10= 560
34+56= 90
90*10= 900
X is about 2 times the size of W so it would be
1:2 (W:X)

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

Suppose the ratio of girls to boys in your school is 19:17. There are 1908 students altogether. Write and solve a system of equations to find the total number of boys and girls in the school.
Answer:
901 boys and 1007 girls
Step-by-step explanation:
let b be the number of boys
let g be the number of girls
[tex]b + g = 1908\\17g = 19b\\g = \frac{19}{17} b\\b+\frac{19}{17} b = 1908\\2\frac{2}{17}b = 1908\\b = 901\\901 + g = 1908\\g = 1007[/tex]
Guthrie made the input-output table shown below.
Input (x)

Output (v)

4
Which of the following equations is true for all values in Guthrie's input-output table?
AI +3 = y
B :+7=y
C 3x+1=y
D) 4.1 - 1=y
9514 1404 393
Answer:
C 3x +1 = y
Step-by-step explanation:
x-values increase by 1 from row to row.
y-values increase by 3 from row to row.
The slope of the linear function is the ratio of the y-increase to the x-increase:
m = ∆y/∆x = 3/1 = 3
The only offered choice with an x-coefficient of 3 is ...
C 3x +1 = y
__
If you check this against the table entries, you find it fits.
3(1) +1 = 4
3(2) +1 = 7
and so on.
