A line has a slope of -1/2and a y-intercept of -2.
Answer:
Step-by-step explanation:
y + 2= -1/2(x - 0)
y + 2 = -1/2x + 0
y = -1/2x - 2
-1/2x = -2
x = 4
Solve:
(Vx + 2)(Vx - 2) = 0
X=
Answer:
x = 4
Step-by-step explanation:
Given:
(√x + 2)(√x - 2) = 0
Required:
Find x
SOLUTION:
√x(√x - 2) + 2(√x - 2) = 0 (distributive property)
x - 2√x + 2√x - 4 = 0
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4

Answer:
The answer is 60
Step-by-step explanation:
How to find what percent of X is Y. Use the percentage formula: Y/X = P% Example: What percent of 60 is 12? Important! The result will always be in decimal form, not percentage form.
(i know this isn’t the clearest formula but its what i used)
Answer:
60
Step-by-step explanation:
To make this problem a little easier, think of 80% as 4/5.
(4/5 = 48/x) ~the unknown is represented by x
After cross multiplying, or "the butterfly method" you would get:
4x = 5(48)
4x = 240
240/4 = 60!
A student wrote the following equation for the graph: y = -3/2 - 4. This is incorrect. What is the mistake? What is the correct equation?

y=-2 3/4(-4)
y=3/2. 4
y= 3×4/2
y =12/2
12/2 =6

Answer:
h(x) = -x² + 11 x + 2
Step-by-step explanation:
Explanation:-
Given that the functions are
f(x) = 2 x² - 5x -3
g(x) = x² + 6x -1
h(x) = g(x) - f(x)
= x² + 6x -1 - (2 x² - 5x -3)
= - x² + 6 x +5x -1+3
= -x² + 11 x + 2
h(x) = -x² + 11 x + 2
Final answer:-
h(x) = -x² + 11 x + 2
16x-8-14x=10 show work
Answer:
x=9
Step-by-step explanation:
Original equation: 16x-8-14x=10
Combine like terms: 2x-8=10
Add 8 to both sides: 2x=18
Divide by 2 on both sides: x=9
Let me know if this helps!
Answer:
x=9
Step-by-step explanation:
16x-8-14x=10
16x+-8+-14x=10
(16x+-14x)+(-8)=10 ( Combine like terms)
2x-8=10
Add 8 to both sides
2x-8=10
+8 +8
2x=18
Divide both sides by 2
2x=18/2
x=9

Reflect the figure across the x-axis then across the y-axis.
Answer:
A' is (-1,-1) B' becomes (-1,-4) C' becomes (-3,-1)
Step-by-step explanation:
To take a shortcut, reflecting a figure across both axes is the same as rotating a figure 180 degrees about the orgin using formula x,y goes to -x,-y but to explain it. Use formula (x,y) goes to (x,-y) to reflect it across x-axis then use formula (x,y) goes to (-x,y) to reflect it across y-axis. A' becomes -1,-1. B' becomes -1,-4 . C' becomes (-3,-1)
Show that the triangles are similar by comparing the ratios of the corresponding sides. Simplify your answer completely in order to be able to compare the ratios of the corresponding sides. Please help
Answer/Step-by-step explanation:
AC = 1.2
AB = 4
BC = 2.6
DF = 3
DE = 10
EF = 6.5
Thus:
[tex] \frac{DE}{AB} = \frac{10}{4} = \frac{5}{2} [/tex]
[tex] \frac{DF}{AC} = \frac{3}{1.2} = \frac{3*10}{1.2*10} = \frac{30}{12} = \frac{5}{2} [/tex]
[tex] \frac{EF}{BC} = \frac{6.5}{2.6} = \frac{6.5*10}{2.6*10} = \frac{65}{26} = \frac{5}{2} [/tex]

compare-and-contrast analysis of how culture shapes the heroes in Heart of a Samurai and Black Ships Before Troy. Use transition words in your draft to help clarify relationships of ideas. KWHL What do you know? What do you want to know? How will you learn? What have you learned?
Answer:
Culture has a significant impact on heroes. For starters, it influences how a person or character perceives a particular situation or idea, as well as their point of view on a variety of ideas and topics. Next, it has an impact on how the hero is portrayed in the story. Third, it influences how a character reacts to an idea or situation.
Culture has an impact on heroes. We see an example of this in 'Black Ships Before Troy,' where in Achilles' culture, to be a hero, you must be brave and fight. This is also evident in 'Heart of a Samurai,' where Manjiro's culture dictates that in order to be a hero, you must provide for your family.

A sample of assistant professors on the business faculty at state supported institutions in Ohio revealed the mean income to be $32,000 for 9 months with a standard deviation of $3,000. Using Chebyshev's Theorem, what is the proportion of faculty that earns more than $25,250 but less than $38,750
Answer:
The proportion of faculty that earns more than $25,250 but less than $38,750 is 0.8025.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].
In this question, we have that:
Mean of 32000, Standard deviation of 3000.
Using Chebyshev's Theorem, what is the proportion of faculty that earns more than $25,250 but less than $38,750
This is within 38,750 - 32,000 = 32,000 - 25,250 = $6,750 of the mean.
Value of k:
This is k standard deviations from the mean. k is given by:
[tex]k = \frac{6750}{3000} = 2.25[/tex]
Proportion:
The percentage is:
[tex]p = 100(1 - \frac{1}{(2.25)^{2}}) = 80.25[/tex].
So the proportion is 0.8025
