Answers:
Upper Limit = 2.55 cc
Lower Limit = 2.25 cc
cc stands for "cubic centimeters".
==========================================
Explanation:
The tolerance tells us how much we can go over or under our target. It's our margin of error. We add and subtract the tolerance (0.15) from the target we're trying to aim for (2.4)
So the lowest dosage allowed is 2.4-0.15 = 2.25 cc
The highest dosage allowed is 2.4+0.15 = 2.55 cc
The upper limit is 2.55 cc while the lower limit is 2.25 cc
On a number line, we would find that 2.4 is at the midpoint of 2.25 and 2.55; so its at the center of those lower and upper bounds. The distance from the center to each endpoint is the same. That distance would be the tolerance 0.15

Substitute: 5 - 1Subtract: 4Factorise fully 6x² - 15x
Answer:
3x(2x - 5)
Step-by-step explanation:
because you have x² that means that you have to timse x by x to get x².
6 divided by 15 gets you a decimal but both number goes into the 3 times table
Therefor 6x² - 15x = 3x(2x-5)
If you need to check just times 2x by 3x which would get you 6x² and 5 by 3x which would get you 15x
Answer:
3x(2x-5)

6x + 2 - 8x + 7 = 4x + 1 A. 4/3 B. 3/4 C. -4/3 D. -3/4 oc A D B
Answer:
A
Step-by-step explanation:
Given
6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

-3/7m=12
A: M= -28
B: M= -26
C: M= 26
D: M= 28
Answer:
A
Step-by-step explanation:
Answer:
-3/7m=12
-3m/7=12 multiplying by 12 on both sides
-3m=12x7
-3m=84
divide by -3
-3m/-3= 84/-3
m= -28

What is 8q+12=4(3+3q)
Answer:
q = 0
Step-by-step explanation:
8q + 12 = 4( 3 + 3q )
Distributive property
8q + 12 = 4 ( 3 + 3q )
8q + 12 = 12 + 12q
Inverse operations
8q + 12 = 12 + 12q
-8q -8q
12 = 12 + 4q
-12 -12
0 = q
q = 0
Answer:
Q = 0
Step-by-step explanation:
1. Expand.
8q + 12 = 12 + 12q
2.cancle 12 on both sides.
8q = 12q
3. Move all terms to one side.
8q - 12q = 0
4. simplify 8q - 12q to -4q.
-4q = 0
5. Divide both sides by -4.
q=0
therefor, the answer is q=0
Melissa is making clothes for her dolls. She has 7/8 yard of fabric. Each doll shirt requires 2/7 of a yard of fabric. How many whole shirts can she make for her dolls?
Answer:
She can make three shirts and will have 7/56 left.
Step-by-step explanation:
49/56-14/56=35/56 (one shirt) 35/56-14/56=21/56 (two shirts) 21/56-14/56=7/56 (three shirts)
The partial factorization of x2 – x – 12 is modeled with algebra tiles.
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x, 3 are labeled +. 1 tile is in the Factor 2 spot and is labeled + x. 20 tiles are in the Product spot: 1 is labeled + x squared, 3 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 12 tiles below the + x tiles are labeled negative.
Which unit tiles are needed to complete the factorization?
Answer:
x² – x – 12 = (x – 4)(x + 3)
Step-by-step explanation:
Identify two numbers that add to -1 and multiply to -12, let's call them p and q.
So ax² + bx + c = (x + p)(x + q)
pq = c
p + q = b.
It is easier to find these numbers by finding factors of -12.
This can be done by splitting the number up until all the numbers are prime.
-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)
There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.
We can eliminate them by adding them up.
6 + -2 = 4 ≠ -1 so that can't be it.
-6 + 2 = -4 ≠ -1 so that can't be it either.
-3 + 4 = 1 ≠ -1
therefore p and q are 3 and -4 because 3 + -4 = -1.
so x² – x – 12 = (x – 4)(x + 3)
p = -4, and q = 3.
(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

The Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The line shown in the image is horizontal, i.e. all of its points have the same y-coordinate regardless of their x-coordinate.
Take two random points on the line like (0,-2) and (2,-2), the slope is:
[tex]\displaystyle m=\frac{-2+2}{2-0}=0[/tex]
The slope is zero
Answer: C. Zero
