Answer:
m=-3
x1,y1=1,-5
we have,
y-y1=m(x-x1)
y-(-5)=-3(x-1)
y+5=-3x+3
3x+y+2=0 is the required eqn
What is the value of the expression when n = 3?
- 2n(5 + n-8-3n)
O 12
0 24
O 42
O 54
Answer:
-(2×3)×(5+3-8-(3×3))
-(6)×(5+3-8-9)
-6×-9
54
Answer:
The correct answer is 54
Option D
Step-by-step explanation:
All you really need to do is replace the n for 3 when you do so you will get
-2(3)(5+3-8-3(3)) = 54
The () represents multiplication.

Answer:
Choice D
Step-by-step explanation:
Since it is a straight one line, the y-intercept (3) stays the same. For the x, it changes so you will have to add both x intercept (2 and 10) and divide by 2. So that gives 12/2 =6 (the x intercept), and since it's one straight line the y intercept remains the same (3)

13) Mrs. Johansen baked 56 cupcakes for the bake sale. At the end of the
day she determined there was a 75% decrease in the number of cupcakes.
How many cupcakes were left? *
Answer:
14 cupcakes
Step-by-step explanation:
75% is equivalent to 3/4 so 56 divided by 4 times by 3
56 divided by 4 is 14 X 3 = 42
56-42 leaves you with 14 cupcakes
1. 87% of 83
2. 100% of 32
3. 89% of 81
4. 22% of 73
5. 36% of 76
6. 45% of 23
7. 50% of 88

Complete the table of values for y=3x - 1
Answer:
To complete the table for the function:
y = 3*x - 1
We just need to replace the values of x, and that will give use the correspondent value of y.
when x = -2, we have:
y = 3*(-2) - 1 = -6 - 1 = -7
when x = 0, we have:
y = 3*(0) - 1 = -1
when x = 1 we have:
y = 3*(1) -1 = 3 - 1 = 2
when x = 3 we have:
y = 3*(3) - 1 = 9 - 1 = 8
Then the table is:
x -2 -1 0 1 2 3
y -7 -4 -1 2 5 8
Now, to graph the line, we just need to find those points in the grid, and then draw a line that passes through all of them, the line will be something like the one in the image below.
Now, to estimate the value of y when x = 2.5
We first need to locate x = 2.5 in the horizontal grid, now let's do a vertical line upwards. When this vertical line touches the line of the graph, we see which value of y (the vertical axis) corresponds with that.
In this case, when x = 2.5, y = 6.5

Steven’s cat drinks water from a bowl. The following function represents the ounces of water left in the bowl in terms of hours since it was filled.
y= -1/2x + 4
Part A
To interpret this function, first determine which variable represents which quantity in the situation. In the equation, x represents the independent variable and y represents the dependent variable. Which variable represents the ounces of water left in the bowl?
Answer:
Step-by-step explanation:
Number of ounces is the dependent and the y represents ounces of water left in the bowl
Answer:
The number of ounces of water left in the bowl depends on the number of hours since the bowl was filled. So the number of ounces is the dependent quantity. The y-variable represents the dependent quantity. So, the y-variable represents the ounces of water left in the bowl.

Please help if you can i really need it
Answer:
9
Step-by-step explanation:
60 requests are made.
Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:
[tex](0.25)(60)=15\\[/tex]
So Spencer gets 15 requests. Now do the same process for Tanvi:
[tex](0.10)(60)=6[/tex]
So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:
[tex]15-6=9[/tex]
Therefore, Spencer gets 9 more requests than Tanvi.
Jessica has $267 in her checking account. She writes a check for $33 to pay her cable bill. Will the cable bill check be positive or negative in your bank account ?
Answer:
negative
Step-by-step explanation:
Answer:
Negative
Step-by-step explanation:
Every time you pay for something it's negative. Think about it, when your parents pay for bills do they give money or get money? They don't get paid to spend electricity, water, and e.t.c.
so if your bill is 33 and you have 267 then,
267 - 33 = 234
What is the value of E(-1) n (3n+2)?
====================================================
Explanation:
The weird looking E symbol is the greek uppercase letter sigma. It refers to a sum.
It tells us to add up terms in the form (-1)^n*(3n+2) where n is an integer ranging from n = 1 to n = 4.
------------------
If n = 1, then we have
(-1)^n*(3n+2) = (-1)^1*(3*1+2) = -5
Let A = -5 as we'll use it later.
------------------
If n = 2, then
(-1)^n*(3n+2) = (-1)^2*(3*2+2) = 8
Let B = 8 since we'll use this later as well
------------------
If n = 3, then
(-1)^n*(3n+2) = (-1)^3*(3*3+2) = -11
Let C = -11
-------------------
If n = 4, then
(-1)^n*(3n+2) = (-1)^4*(3*4+2) = 14
Let D = 14.
--------------------
We'll add up the values of A,B,C,D to get the final answer
A+B+C+D = -5+8+(-11)+14 = 6
This means that
[tex]\displaystyle \sum_{n=1}^{4}(-1)^n(3n+2) = 6[/tex]

2 x 1/4 + 3/4 please help meeeeeee
Step-by-step explanation:
2 * (1/4) + (3/4)
= (2/4) + (3/4)
= 5/4 or 1.25.
Answer:
5/4
Step-by-step explanation:
First multiply 2 x 1/4
so you would do 2/1 x 1/4
and so that would give you 2/4
and then it would be 2/4 +3/4
and since they have the same denominator
add the numerator which will give you 5/4 or 1 1/4
5 ≤ - 3x- 3 ≤ 10 solve the inequality for x
Answer:
[tex] - \frac{8}{3} \geqslant x \geqslant - \frac{13}{3} [/tex]Step-by-step explanation:
to understand thisyou need to know about:inequalitysolving inequalityPEMDASgiven:5 ≤ - 3x- 3 ≤ 10
to solve:x
let's solve:few notes about inequality
the direction of the inequality doesn't change if you
Add (or subtract) a number from both sidesMultiply (or divide) both sides by a positive numberSimplify a sidethe direction of the inequality does change
if you
Multiply (or divide) both sides by a negative numberSwapping left and right hand sides[tex]step - 1 : difine[/tex]
[tex]5 \leqslant - 3x - 3 \leqslant 10[/tex]
[tex]step - 2 : \\ add \: 3 \: in \: each \: sides[/tex]
[tex]5 + 3 \leqslant - 3x - 3 + 3 \leqslant 10 + 3[/tex]
