Answer to solving for y: y = -2.
Answer for simplifying the expression: -12y - 4.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We are given that x = -4y and that the equation is 3x + 2y = 20.
We need to evaluate.
3x + 2y = 20
||
\/
3(-4y) + 2y = 20.
To solve for y, y = -2.
||
\/
3(-4y) + 2(-2) = -12y - 4.
Answer:
y= -2 x=8
Step-by-step explanation:
3 (-4y)+2y=20
-12y+2y=20
-10y=20
y= -2
x= -4 (-2)
x=8

Factor the following expression using the GCF. Type your factored expression below.
4xy + 12w + 12Z
Answer:
4(xy + w + z)
Step-by-step explanation:
The expression to be factored is:
4xy + 12w + 12z
Factoring an equation involves taking out common terms from the expression that will then make it more simpler and simplified.
To solve this problem, we need to find the factors of the given terms:
4xy
12w
12z
The numbers given as coefficients of the variables are;
4 12 12
A factor is any integer that divides a number evenly;
Factors of 4 are 1, 2 and 4
12 are 1, 2,3,4,6 and 12
The common factors between 4 and 12 are those numbers that can divide both digits:
These are 1, 2, and 4, they are common to both
Now, the greatest common factor is the highest of this factors which is 4
Therefore, the greatest common factor of 12 and 4 is 4
Also, xy, w and z has no common factors
Factoring
4xy + 12w + 12z = 4(xy + w + z)

Answer:
D. two real solutions
Step-by-step explanation:
p²+5 = 6p
p² - 6p +5 =0
D = b² - 4ac = (-6)² - 4*(1)*5 = 36 - 20 = 16
D > 0, so this equation has 2 real solutions

compare the two groups of data. which statement is true?
Answer:
a) both have the same spread
Step-by-step explanation:
Mean of Brand A > Mean of Brand B
Median of A > Median of B
Spread of:
A: 22 - 18 = 4
B: 18 - 14 = 4
The spread of the data which is obtained by calculating the Interquartile range of each distribution since the distributions are skewed is 2 for brand A and brand B. Hence, the spread is the same.
The distribution of BRAND A chips :
18, 19, 19, 19, 19, 19, 19, 20,20,20,20,20,20,21,21,21,21,21,21,22
The Upper quartile, Q3 ;
Q3 = 0.75 × (n + 1)th term
Q3 = 0.75 × 21 = 15.75 th term = 21
The Lower quartile, Q1 ;
Q1 = 0.25 × (n + 1)th term
Q1 = 0.25 × 21 = 5.25 th term = 19
The IQR = Q3 - Q1 = (21 - 19) = 2
The distribution of BRAND B chips :
14,14,14,14,14,14,14,14,15,15,15,15,15,15,16,16,16,16,16,18
The Upper quartile, Q3 ;
Q3 = 0.75 × (n + 1)th term
Q3 = 0.75 × 21 = 15.75 th term = 16
The Lower quartile, Q1 ;
Q1 = 0.25 × (n + 1)th term
Q1 = 0.25 × 21 = 5.25 th term = 14
The IQR = Q3 - Q1 = (16 - 14) = 2
Therefore, the spread of distribution of BRAND A and B are the same.

A linear function has a slope of Negative StartFraction 7 Over 9 EndFraction and a y-intercept of 3. How does this function compare to the linear function that is represented by the equation y + 11 = Negative StartFraction 7 Over 9 EndFraction (x minus 18)?
Answer:
They are the same line written in different forms.
Step-by-step explanation:
Given a linear function with a slope of [tex]-\frac{7}{9}[/tex] and a y-intercept of 3.
The equation of the line in the slope-intercept form is given as:
[tex]y=-\frac{7}{9}x+3[/tex]
Given the other line,
[tex]y+11=-\frac{7}{9}(x-18)[/tex]
Simplified:
[tex]y+11=-\frac{7}{9}x+14\\y=-\frac{7}{9}x+14-11\\y=-\frac{7}{9}x+3[/tex]
The two lines are one and the same line.
Answer:
They are the same line written in different forms.
What is the greatest common factor of 4x^3
and 8x^2?
Answer:
the gcf is 4
Step-by-step explanation:
Final answer:
To find the greatest common factor of 4x³ and 8x², we look at the numerical coefficients and the variables separately. The GCF of the coefficients 4 and 8 is 4, and since x² is the lowest power of x common in both terms, the GCF is 4x².
Explanation:
The greatest common factor (GCF) of two expressions, like 4x³ and 8x², involves finding the highest degree of common terms they share. First, let's compare the numerical coefficients; 4 and 8. The GCF of 4 and 8 is 4. Next, we'll look at the variable part. The lowest exponent of x that appears in both terms is 2. Therefore, the GCF is the product of the GCF of the coefficients and the lowest power of x, which is 4x².

Find the exact volume of the cylinder.
A) 14π m3
B) 28π m3
C) 56π m3
D) 112π m3
(the height is 7 and the radius is 2)
Answer:
Option B) [tex]28\pi\text{ m}^3[/tex]
Step-by-step explanation:
We are given the following in the question:
Radius of cylinder, r = 2 m
Height of cylinder, h = 7 m
We have to find the volume of the cylinder.
Volume of cylinder =
[tex]V = \pi r^2 h[/tex]
where r is the radius and h is the height of the cylinder.
Putting values, we get,
[tex]V = \pi (2)^2(7)\\V = 28\pi\text{ cubic meter}[/tex]
Thus, the volume of cylinder is
Option B) [tex]28\pi\text{ m}^3[/tex]

A cylinder and a cone start with the same radius and height. The radius of the cone is then tripled, and the height of the cone is cut in half. The radius of the cylinder stays the same, but the height of the cylinder is doubled. Which change produces a greater increase in volume (i.e., which figure’s volume increases by a larger factor)? Justify your answer. Write “pi” for ''pi symbol'' and “r^2”.
Answer:
The change in the cone produces a greater increase in volume.
Step-by-step explanation:
Let's start with the cone.
[tex]V = \frac{1}{3} \pi r^{2} h[/tex]
[tex]V = \frac{1}{3} \pi 3r^{2} \frac{h}{2}[/tex] (In your case, you would type V = 1/3pi3r^2h/2)
The changes that occurred are [tex]3^{2}[/tex] and [tex]1/2[/tex]. When we add these together we get [tex]9/2[/tex].
Now the cylinder.
[tex]V = \pi r^{2} h[/tex]
[tex]V = \pi r^{2} 2h[/tex] (In your case, you would type V = pir^2 2h)
The change that occurred is [tex]2[/tex].
[tex]9/2[/tex] is greater than [tex]2[/tex] which means that the change in the cone produces a greater increase in volume.
Answer:
Step-by-step explanation:
For the cone V k1= (Pi/3) .R squared .H
V k2= (pi/3) . (3R)squared . (H/2)=(9/2) .(PI/3) . R squared.H
=(3pi/2) R.squared.H
3pi/2
nk= 2/ pi/3
N k= 9/2
For the cylinder
V c1=Pi .R squared.H
V c2= Pi.R squared.(2H)
N c=V c2/V c1=2
Cone has greatest change in volume
