Answer:
Sample response:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>
What is a common factor of 12x 2 − 5x − 3 and 6x 2 − x − 1 ?
Answer:
The common factor is (3x+1).
8=16+(y-1)
how do i solve this?
Answer:
y=-7 :)
Step-by-step explanation:
remove the parentheses
8=16+y-1
subtract the numbers
8=15+y
move variable to the left-hand side and change it's sign
-y=15-8
subtract the numbers
-y=7
change the sides on both sides of the equation
y=-7
hope it help <3
Answer:
y=2
Step-by-step explanation:
8= 16y + 16
16-8= 16y
8= 16y
y= 2
Write an  equation of the line that passes through please (2, -2) and is parallel to line y=3x+9
Answer: y=3x-8
Step-by-step explanation:
To find the parallel line, you know that the slope must stay the same. If the slope is different, the graphs will touch at one point. This goes against parallel lines as they NEVER touch or cross.
y=3x+b
We can use the given point to find the y-intercept.
-2=3(2)+b [multiply]
-2=6+b [subtract both sides by 6]
b=-8
Now that we have found the y-intercept, we can finish our equation.
y=3x-8

Given g(x) = 3x+3, find g(6)
Answer:
g(6)=21
Step-by-step explanation:
Given g(x)= 3x+3, Find g(6)
1. Replace g(x) with g(6), and x with 6. The equation will now look like this: g(6)=3(6)+3
2. Multiply 3 and 6, to equal 18. The equation will now look like this: g(6)=18+3
3. Add 18 and 3 to equal 21. The Answer is g(6)=21

A 3-gallon tub of ice cream yields about 90 scoops of ice cream. There are roughly 3785 cubic centimeters in 1 gallon. Determine the radius of each scoop, to the nearest tenth.
Answer:
The radius of the scoop is r = 3.1 cm
Step-by-step explanation:
Since 3 gallons yields 90 scoops, and 1 gallon = 3785 cm³.
3 gallons = 3 × 3785 cm³ = 11355 cm³
So we have 11355 cm³ in 3 gallons which is also the volume of 90 scoops.
Since 90 scoops = 11355 cm³, then
1 scoop = 11355 cm³/90 = 126.2 cm³
Now, if each scoop is a sphere, the volume is given by V = 4πr³/3 where r is the radius of the scoop. Since we need to find the radius of the scoop, r, making r subject of the formula, we have
r = ∛(3V/4π)
Substituting V = 126.2 cm³, we have
r = ∛(3× 126.2 cm³/4π)
= ∛(378.6 cm³/12.57)
= ∛30.13 cm³
= 3.1 cm
So, the radius of the scoop is r = 3.1 cm

An architect measures a beam to be 96.55 centimeters long, with an accuracy of plus or minus 0.02 centimeter. Which equation can be used to find the limits of the actual length of the beam? |x−96.55|=0.02start absolute value x minus 96 point 5 5 end absolute value is equal to 0 point 0 2 |96.55−0.02|=xstart absolute value 96 point 5 5 minus 0 point 0 2 end absolute value is equal to x |x+96.55|=0.02start absolute value x plus 96 point 5 5 end absolute value is equal to 0 point 0 2 |96.55+0.02|=x
Answer:
|96.55−0.02|= x
|96.55+0.02|=x
Step-by-step explanation:
Given that:
Measured length of beam = 96.55 cm
Measurement accuracy = plus or minus (± 0.02cm)
Limits of actual length of the beam:
Let limit of actual length = x
Lower limit :
|measured length - accuracy| = x
|96.55 - 0.02| = x
96.53) x
Upper limit :
|measured length + accuracy| = x
|96.55 + 0.02| = x
96.57 = x

Answer:

Step-by-step explanation:
In math, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

Between each point of "5" there are 10 little squares in between and each number passes every 2 little squares. So we can use this to solve the questions.
Part A:
Count all the pupils who scored "more" than 7 using the assumption we made above.
12 scored more than 7
Part B:
Since we know that 14 scored more the seven, count all of the pupils who scored 7 and less.
15 scored a seven or less.
Add both numbers.
12 + 15 = 27 total pupils
Part C:
The assumption we had to make was to count each two little squares that represent one pupil to find the answer for Part B.

What is the slope of a line that is perpendicular to the graphed line?
Answer:
2
Step-by-step explanation:
To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)
The formula of a slope is (y value of second point [tex]-y[/tex] value of first point) divided by (x value of second point [tex]-x[/tex] value of first point):
[tex]\frac{0-4}{8-0} =-\frac{1}{2}[/tex]
