Step-by-step explanation:
Given
[tex]12x = 48 - 8y[/tex]
[tex]10x + 8y = 38[/tex]
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
[tex]12x = 48 - 8y[/tex]
[tex]10x + 8y = 38[/tex]
Rewrite the second equation
[tex]12x = 48 - 8y[/tex]
[tex]10x = 38 - 8y[/tex]
The coefficient of y are the same, so we subtract;
[tex]12x - 10x = 48 - 38 -8y -(-8y)[/tex]
[tex]12x - 10x = 48 - 38 -8y +8y[/tex]
[tex]2x = 10[/tex]
[tex]x= 5[/tex]
See that y has been eliminated
Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)
Answers
Answer:
(-1/12)(x-3)(x-8)
or
[tex]-\frac{x^2-11x+24}{12}[/tex]
Step-by-step explanation:
If something has x intercepts of (3,0) and (8,0) we can write the following
y=(x-3)(x-8)
To make the y intercept (0,-2) we will mulitply this by some constant, a
y=a(x-3)(x-8)
to solve for a set y= -2 and x=0
a(0-3)(0-8)= -2
a(-3)(-8)= -2
24a= -2
a= -1/12
Which means our final equation is
(-1/12)(x-3)(x-8)
which in standard form is equal to
[tex]-\frac{x^2-11x+24}{12}[/tex]
Find the measure of angle QZT.
Answers
========================================================
Explanation:
Minor arc QV is 80 degrees because it adds to minor arc VU = 100 to get 80+100 = 180. Note how angle QPU = 180, since it's a straight line and QU is a diameter of the circle.
Add up the minor arcs
TUUVVQto get: 44+100+80 = 224
This means arc TUQ is 224 degrees. Inscribed angle QZT subtends arc TUQ. Use the inscribed angle theorem to say that the inscribed angle is half of the arc it cuts off.
angle QZT = (arc TUQ)/2
angle QZT = 224/2
angle QZT = 112 degrees

Write the equation of the line that passes through the points (5, -1) and
(2, -1). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.
Answers
Answer:
y = -1
Step-by-step explanation:
First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.
Which group of numbers could be the measures of the sides of a right

Answers
Answer:
it's B. i individually solved all of them using the pythagorean theorem.
Step-by-step explanation:
"The Pythagorean theorem states that, in a right triangle, the square of the length of the hypotenuse (the side across from the right angle) is equal to the sum of the squares of the other two sides. So if the length of the hypotenuse is c and the lengths of the other two sides are a and b, then c^2 = a^2 + b^2"

square everything on both sides and ur left with

Which function has the same y-intercept as the function
y = ſc – 3?
2 + 4y = 12
- x + 3y = 6
6x – 7y= 21
x + 3y = -3
Answers
In order to find this answer you need to convert the answer choices into y intercept form by isolating the y variable to one side of the equation.
6x-7y=21
-7y=-6x+21
y=6/7x-3
As you can see when you change the form of this equation, the y intercept is -3.

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist
Answers
Answer:
because the graphs of the two equations overlap each other
Step-by-step explanation:
Equations that have an infinite amount of solutions overlap each other when graphed.
This is because equations with an infinite amount of solutions have a similar equation so when graphed you only see one line

Answers
Answer:
A) P(T) = 30/120 = 1/4
B) P(T) = 50
Step-by-step explanation:
A) P(T) = 30/120 = 1/4
B) P(T) = 1/4 of 200 which is 50
a. Probability that the coin shows tails is [tex]\frac{1}{4}[/tex].
b. 50 number of times the coin shows tails.
What is probability?Probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
Probability = [tex]\frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ favorable \ outcomes}[/tex]
According to the question
a. John throws a biased coin 120 times. It shows heads 90 times.
Probability formula:
Probability = [tex]\frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ favorable \ outcomes}[/tex]
Probability that the coin shows heads = [tex]\frac{90}{120}[/tex] = [tex]\frac{3}{4}[/tex]
Probability that the coin shows tails = 1 - [tex]\frac{3}{4}[/tex] = [tex]\frac{1}{4}[/tex]
b. Carly throws the same coin 200 times.
From a, we know the probability that the coin shows tails is [tex]\frac{1}{4}[/tex].
Number of times the coin shows tails = 200 × [tex]\frac{1}{4}[/tex] = 50
