The percent of the class who voted for Math also voted for Science is 38.8%
How to find the percent who voted math and also voted for science?Therefore,
1 = p(m) + p(s) - p(m ∩ s)
Hence,
p(m) = 45% = 0.45
p(s) = ?
p(m ∩ s) = 35% = 0.35
Therefore,
1 = 0.45 + p(s) - 0.35
1 - 0.45 + 0.35 = p(s)
p(s) = 0.9
Therefore,
p(m | s) = 0.35 / 0.9 = 0.38888888888 = 38.8%

Solve for y
x = x (2x - 4) + y
The first x is squared I just can’t put a square in brainly
Answer:
y = −x^2 + 4x
Step-by-step explanation:
x^2 = x (2x - 4) + y
Let's simplify it and we get
x^2 = 2x^2 - 4x + y
Now, we want to get the y by itself
x^2 = 2x^2 - 4x + y
-x^2 = -4x + y
-x^2 + 4x = y
So, our answer is y = −x^2 + 4x

If x is 0, wouldn't that make it 2^0 being one
Answer:
any number raised by power 0 is always one

Answer:
Yes. If x=0, then 2ˣ = 0
Step-by-step explanation:
I presume you mean 2ˣ
Any number raised to the power zero is 1 so if x = 0, 2⁰ = 1. There are debates about what 0⁰ evaluates to but I don' think you need to worry about that for this question

2(x−3 1/2)=10 3/4
Enter your answer as a mixed number in simplest form in the box.
Answer:
x = 71/8
Step-by-step explanation:
Solve for x:
2 (x - (3 + 1/2)) = 10 + 3/4
Put 3 + 1/2 over the common denominator 2. 3 + 1/2 = (2×3)/2 + 1/2:
2 (x - (7/2)) = 10 + 3/4
2×3 = 6:
2 (x - (1/2 6 + 1/2)) = 10 + 3/4
6/2 + 1/2 = (6 + 1)/2:
2 (x - (7/2)) = 10 + 3/4
6 + 1 = 7:
2 (x - 1/2 7) = 10 + 3/4
Put each term in x - 7/2 over the common denominator 2: x - 7/2 = (2 x)/2 - 7/2:
2 ((2 x)/2 - 7/2) = 10 + 3/4
(2 x)/2 - 7/2 = (2 x - 7)/2:
2 (1/2 (2 x - 7)) = 10 + 3/4
(2 (2 x - 7))/2 = 2/2×(2 x - 7) = 2 x - 7:
(2 x - 7) = 10 + 3/4
Put 10 + 3/4 over the common denominator 4. 10 + 3/4 = (4×10)/4 + 3/4:
2 x - 7 = ((4×10)/4 + 3/4)
4×10 = 40:
2 x - 7 = 40/4 + 3/4
40/4 + 3/4 = (40 + 3)/4:
2 x - 7 = ((40 + 3)/4)
40 + 3 = 43:
2 x - 7 = 43/4
Add 7 to both sides:
2 x + (7 - 7) = 43/4 + 7
7 - 7 = 0:
2 x = 43/4 + 7
Put 43/4 + 7 over the common denominator 4. 43/4 + 7 = 43/4 + (4×7)/4:
2 x = (43/4 + (4×7)/4)
4×7 = 28:
2 x = 43/4 + 28/4
43/4 + 28/4 = (43 + 28)/4:
2 x = ((43 + 28)/4)
43 + 28 = 71:
2 x = 71/4
Divide both sides by 2:
x = (71/2)/4
4×2 = 8:
Answer: x = 71/8

What is positive slop?Sean deposits $275 each month into his savings. He started with $1000 in the account.
The slope of the line will be In 10 months the savings will be at ,The graph of this line will y = savings and x = months
When two variables have a positive slope, it implies that they are positively correlated; that is, when x rises, y rises as well, and when x falls, y falls as well. A line on a line graph that has a positive slope rises as the line advances from left to right.Positive slopes are founded on the idea that when x rises, y rises as well, making the ratio of y/x positive. Negative slopes are founded on the idea that when x rises, y falls. This results in a negative change in y and a positive change in x, which yields a negative result.The slope of the line will be,In 10 months the savings will be at,The graph of this line will positive slop.

What kind of function is an exponential function?
An exponential function is a function in which the variable (usually represented by "x") is the exponent, rather than the base.
The most common form of an exponential function is f(x) = b^x, where b is a positive constant known as the base of the function.
Exponential functions can take many different forms, but they all have one thing in common: the variable is in the exponent. In most cases, the base of the function is a positive constant, and the exponent is the input variable. Exponential functions can also be used to model a wide variety of real-world phenomena, such as population growth, compound interest, and decay of radioactive materials.
The graph of an exponential function is always a smooth curve that increases or decreases at an increasing rate. The slope of the curve increases as x increases, which means that the rate of change of the function also increases as x increases.

Solve the system of linear equations by elimination.
-5x+12y=8
2x-8y=0
Answer:
x = -4
y = -1
Step-by-step explanation:
-5x+12y=8
2x-8y=0
We multiply the first equation by 2 and the second equation by 5
-10x + 24y = 16
10x - 40y = 0
-16y = 16
y = -1
Now put -1 back in for y and solve for x
-5x + 12(-1) = 8
-5x - 12 = 8
-5x = 20
x = -4
Let's check
-5(-4) + 12(-1) = 8
20 - 12 = 8
8 = 8
So, x = -4 & y = -1 is the correct answer.

The quadratic equation whose roots -3 and 6 and leading coefficient 4 is 4x²-12x-72 = 0
What is quadratic equation?A quadratic equation is an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x² + 3x + 1 , y = x²+x-1
If the root of the quadratic equation are -3 and 6
then, x = -3 and x= 6
therefore x+3 = 0 and (x-6) = 0
(x+3)(x-6) = 0
with leading coefficient 4,
then 4( x+3) ( x-6) = 0
4 ( x²-6x+3x-18) = 0
4( x²-3x-18) = 0

Here,
Given :
from the graph we can say that -
B = 250
A = 200
Area 0f triangle = 1/2 AB = 1/2 . 250 . 200
Area = 25000sq units
