Solve this system of equations using the substitution method y=5x+4 x+12=y
Answer:
(2,14)
Step-by-step explanation:
Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4
Now subtract 12 from both sides
x=5x-8
Subtract 5x from both sides
-4x=-8
Now you divide them both by -4 which gives you x=2
Now plug x in to any of the equations
y=5(2)+4
y=10+4
y=14
Your final answer is (2,14)

Please someone help me i need this to pass!
Answer:
Step-by-step explanation:
subtrct 2 from every x co-ordinate and add 7 to every y co-ordinate.
What is the domain? Is it (-4,3)
Yes I think you are correct. The domain appears to be the set of x values such that -4 < x < 3 meaning that x is between -4 and 3, excluding each endpoint. In interval notation, that translates to (-4, 3). This of course assumes that we have two vertical asymptotes bookending the left and right sides of the curve, and these vertical asymptotes are at x = -4 and x = 3. If the curve extends beyond these boundaries, then the domain would instead be the set of all real numbers.

Which of the g-values satisfy the following inequality?
7 >_ 12 - 9
Choose all answers that apply:
A: g=4
B: g=5
C: g=6
Answer:
B: g=5
C: g=6
Step-by-step explanation:
Given
[tex]7 \ge 12 - g[/tex]
Required
All possible values of g
We have:
[tex]7 \ge 12 - g[/tex]
Collect like terms
[tex]7 - 12\ge - g[/tex]
[tex]-5\ge - g[/tex]
Divide both sides by -1 [The inequality changes because of negative division]
[tex]5\le g[/tex]
Swap both terms
[tex]g \ge 5[/tex]
This implies that g is greater than of equal to 5
i.e.
[tex]g= \{5,6,7.....\}[/tex]

Why is c speed of light in albert einseins eqation e=mc squared
Answer:
[tex]{\huge\pink{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]
The speed of light (c) is considered a fundamental constant of nature. In the famous relativity equation, E = mc², the speed of light (c) serves as a constant of proportionality, linking the formerly disparate concepts of mass (m) and energy (E).

Consider the function f(x) = V2x – 4. Iff-'(x) is the inverse function of f(x), find
f-16)
Answer:
[tex]f^{-1}(6) = 50[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \sqrt{2x} - 4[/tex]
Required
Find [tex]f^{-1}(6)[/tex]
First, we calculate the inverse function
[tex]f(x) = \sqrt{2x} - 4[/tex]
Express f(x) as y
[tex]y = \sqrt{2x} - 4[/tex]
Swap the positions of x and y
[tex]x = \sqrt{2y} - 4[/tex]
Solve for y: Add 4 to both sides
[tex]4 + x = \sqrt{2y} - 4+4[/tex]
[tex]4 + x = \sqrt{2y}[/tex]
Square both sides
[tex](4 + x)^2 = 2y[/tex]
Divide both sides by 2
[tex]y = \frac{(4 + x)^2}{2}[/tex]
Express y as an inverse function
[tex]f^{-1}(x) = \frac{(4 + x)^2}{2}[/tex]
Next, solve for: [tex]f^{-1}(6)[/tex]
Substitute 6 for x
[tex]f^{-1}(6) = \frac{(4 + 6)^2}{2}[/tex]
[tex]f^{-1}(6) = \frac{(10)^2}{2}[/tex]
[tex]f^{-1}(6) = \frac{100}{2}[/tex]
[tex]f^{-1}(6) = 50[/tex]

Miguel is 4 years older than 2/3 of Harper's age. The sum of their ages is 34. His harper 16?
Answer:
Harper's age = 18
Miguel age = 16
Step-by-step explanation:
Given:
Miguel age = [2/3][Harper's age] + 4
Sum of their age = 34
Computation:
Assume;
Harper's age = a
So,
Miguel age = [2/3][a] + 4
Sum of their age = 34
So,
Miguel age + Harper's age = 34
[2/3][a] + 4 + a = 34
[2a / 3] + a = 34 - 4
[2a + 3a] / 3 = 30
5a / 3 = 30
5a = 90
a = 18
So,
Harper's age = 18
Miguel age = [2/3][a] + 4
Miguel age = 16

Find the missing length indicated
A) 25
B) 5
C) 8
D) 3
Given:
The figure of a triangle.
To find:
The missing length.
Solution:
Let x be the missing length.
Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.
Using Basic proportionality theorem, we get
[tex]\dfrac{6}{8-6}=\dfrac{12-x}{x}[/tex]
[tex]\dfrac{6}{2}=\dfrac{12-x}{x}[/tex]
[tex]3=\dfrac{12-x}{x}[/tex]
[tex]3x=12-x[/tex]
Adding x on both sides, we get
[tex]3x+x=12[/tex]
[tex]4x=12[/tex]
[tex]x=\dfrac{12}{4}[/tex]
[tex]x=3[/tex]
The missing length is 3 Therefore, the correct option is D.
(PLSSSS HELP) Determine which three out of the six points shown below are a solution to the equation x-3y=22 Plot the three points that are in the solution set, draw a line through the three points and then answer the questions below.
Answer:
[tex](-2,8)[/tex] [tex](7,5)[/tex] [tex](1,7)[/tex]
Step-by-step explanation:
Given
[tex]x + 3y = 22[/tex]
Solving (a): The possible coordinates
We have:
[tex](x,y) = (-2,8)[/tex]
This gives:
[tex]x + 3y = 22 \to -2 + 3 * 8[/tex]
[tex]x + 3y = 22 \to -2 + 24[/tex]
[tex]x + 3y = 22 \to 22[/tex]
(-2,8) is a point on the grid
[tex](x,y) = (7,5)[/tex]
This gives:
[tex]x + 3y = 22 \to 7 + 3 * 5[/tex]
[tex]x + 3y = 22 \to 7 + 15[/tex]
[tex]x + 3y = 22 \to 22[/tex]
(7,5) is a point on the grid
[tex](x,y) = (-5,5)[/tex]
This gives:
[tex]x + 3y = 22 \to -5 + 3 * 5[/tex]
[tex]x + 3y = 22 \to -5 + 15[/tex]
[tex]x + 3y = 22 \to 10[/tex]
(-5,5) is a not point on the grid
[tex](x,y) = (1,3)[/tex]
This gives:
[tex]x + 3y = 22 \to 1 + 3 * 3[/tex]
[tex]x + 3y = 22 \to 1 + 9[/tex]
[tex]x + 3y = 22 \to 10[/tex]
(1,3) is a not point on the grid
[tex](x,y) = (1,7)[/tex]
This gives:
[tex]x + 3y = 22 \to 1 + 3 * 7[/tex]
[tex]x + 3y = 22 \to 1 + 21[/tex]
[tex]x + 3y = 22 \to 22[/tex]
(1,7) is a point on the grid
So, we plot the following on the grid
[tex](-2,8)[/tex] [tex](7,5)[/tex] [tex](1,7)[/tex]

A pitcher of iced tea holds 128 ounces. A large orange cooler holds 1792 ounces of iced tea. How many pitchers of iced tea will it take to fill the large orange cooler? * NO LINKS PLZZ!!!
A.12
B.24
C.14
D.18
The big orange cooler will hold 14 pitchers of iced tea. The response is C.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Since a pitcher of iced tea holds 128 ounces, we can find the number of pitchers required to fill the large orange cooler by dividing the total volume of the cooler by the volume of one pitcher:
1792 / 128 = 14
Therefore, it will take 14 pitchers of iced tea to fill the large orange cooler. The answer is C.

A crowd-sourced review platform believes that more and more customers are writing reviews online. The crowd-sourced review platform would like to test the claim that the percent of customers who leave a review online is greater than 72%. They decide to complete a hypothesis test at a 1% significance level. They sample 30 customers, and determine the sample percent to be 90%. The following is the data from this study: Sample size =30 customers Sample proportion =0.90 Identify the null and alternative hypothesis for this study by filling in the blanks with the correct symbol (=,≠,<, or > to represent the correct hypothesis.)
Answer:
H0 : P = 0.72
H1 : P > 0.72
Step-by-step explanation:
Claim is to test that percentage of customers who leave a review is greater than 72%
From the information given :
P0 = 72/100 = 0.72
The null hypothesis, H0 : P = 0.72
Alternative hypothesis claims the proportion is greater than 0.72 and from the sampling result obtained, phat = 0.90
Hence,
Alternative hypothesis, H1 : P > 0.72
