Since you're trying to find f(-3), your function that you have to plug -3 into will be f(x).
f(-3) = -2(-3)^2+(-3)+3
f(-3) = -2(9)+(-3)+3
f(-3) = -18-3+3
f(-3) = -18 is your final answer

What is the distance between the
points (-8, -3) and
(-2, -5)?
Question
What is the distance between the
points (-8, -3) and (-2, -5)?
Answer:
let the distance between the points be A(-8, -3) = x_1 ,y_1 and B (-2, -5)
= x_2 ,y_2.
Now,
According to the Pythagoras theorem,
d = √ (x _2 −x _1 )^2+(y _2 −y _1 )^2d=√(-2-(-8))^2 + (-5(-3))^2d= √(6)^2 + (15)^2d= √36+225d= √261d= 3√29Therefore d(distance) = 3√29
1. Identify each pair of angles as complimentary, supplementary, or neither.
Answer:
Neither
Step-by-step explanation:
One angle is 90
Another angle is 43
Complimentary angle: If sum of two angles is 90, then they are complimentary.
Supplementary angle: If sum of two angles is 180, then they are supplementary.
So, the above mentioned are neither of these

H(x) = 1/x+2 and k(x) = 3x - 4
h[k(x)] =
A.(3x - 4)/(x+2)
B. 1/(4x - 2)
C. 1/(3x - 2)
Answer:
= 1/ (3x-2)
Step-by-step explanation:
H(x) = 1/(x+2)
k(x) = 3x - 4
h[k(x)] = place the function k(x) in for x in the function h(x)
= 1/(3x-4 +2)
Combine like terms
= 1/ (3x-2)
Hey there! I'm happy to help!
What we need to do is take the value of k(x) which is 3x-4 and plug it into the function h(x).
This is because our x in the function h[k(x)] is k(x), so we will substitute that value for x in that formula and that will give us our answer.
H[(k(x)]=1/(3x-4+2)
And combine like terms
H[(k(x)]=1/(3x-2)
So, our answer is C. 1/(3x-2)

Step-by-step explanation:
Given that,
Mary Smith ordered 3/4 truckload of merchandise.
If approximately 1/3 of the merchandise has been unloaded.
To find,
How much remains to be unloaded?
Solution,
Remaining amount = Total truckload - Unloaded amount
Let x is the remaining amount. So,
[tex]x=\dfrac{3}{4}-\dfrac{1}{3}\\\\x=\dfrac{3(3)-4}{12}\\\\x=\dfrac{5}{12}[/tex]
Answer:
So, the remaining amount is [tex]\dfrac{5}{12}[/tex].

Straight Line Graphs
View One Minute Version
Overview
Answer:
a) linked a screenshot of the graph.
b) when y=1 x=.5
Step-by-step explanation:
4 is the slope, which makes the graph angle different. Starting at the origin (0,0) if you go over 1 and up 4 that is how you can draw the slope on a graph.
-1 makes the line go to the right 1 time so instead of the graph being on the origin (0,0) it will be placed on the coordinate points of (1,0)
To find the x value. Find 1 on the y-axis of the line graph. Go to the right to find where the line intersects. After you find that go straight down to find the x-value (0.5)

What is the slope for (5,-1) ,(4,-3)
Answer: slope = 2
Step-by-step explanation:
slope formula is y2-y1 / x2-x1
let’s make 5, x1 and -1, x2, 4, x2 and -3, y2.
if you plug the numbers in it should look like
-3 - -1 / 4-5 = -2/-1 = 2 (positive two). it’s a positive 2 because a negative times a negative is a positive and a positive times a negative is a negative
Write as an expression. The quantity 10 less than x, divided by 4
Answer:
[tex]\frac{x-10}{4}[/tex]
Step-by-step explanation:
When it says less then that means 10 is less than x. You can write divided by 4 either by putting it as a fraction or by using the division sign as "x-10 / 4."
The quantity 10 less than x, divided by 4 is mathematically given as (10 - x) / 4.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Division means the separation of something into different parts, sharing of something among different people, places, etc.
If the quantity 10 is less than x, then the expression will be
⇒ 10 - x
Then the quantity 10 less than x and divided by 4, then the expression will be
⇒ (10 - x) / 4
The quantity 10 less than x, divided by 4 is mathematically given as (10 - x) / 4.

Answer:
Step-by-step explanation:
So we know that it cost $600 in material to build the couch,
and then we know it cost $2000 extra to install and setup the couch,
so it cost 2,600 to build and install one couch,
So the first answer is 2,600
Now to build and install 15 of them we do 2,600 x 15 = $39,000
So it cost 2,600 to make and install one
And 39,000 to make and install 15.
But it only cost $600 to build one
and $9,000 to make 15 without installation fees.
