What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be A = 42

Now , let the percentage of the number A = 23 %

And , the equation will be

The 23 % of the number be = y

So , y = 23 % of 42

And , the equation is

y = ( 23 / 100 ) x 42

y = 0.23 x 42

On simplifying the equation , we get

y = 9.66

y ≈ 9.7

Therefore, the value of y is 9.7

Hence , The value of 23 % of 42 is 9.7

Answer:

y=11/5

Step-by-step explanation:

first divide by 5 on both sides

y+2/5=-13/5

subtract 2/5 on both sides to isolate the y

y=11/5

:))

Answer:

y=-3

Step-by-step explanation:

5(y+2/5) = -13

5y+2 = -13

subtract 2 from each side

5y+2-2 = -13-2

5y = -15

divide each side by 5

5y/5 = -15/5

y=-3

check:

5(y+2/5) = -13

substitute -3 for y

5(-3)+2/5) = -13

-15+2= -13

-13 = -13

The only statement that is true regarding the given graph of polynomial b(x) is; Option D; Over the interval [0, 1], b(x) is negative and is decreasing.

The given graph represents the polynomial b(x). Let us look at the options;

Option A; Over the interval (0, 1), we can see that the curve is decreasing from b(x) = 0 to b(x) = -2. Thus, the statement is wrong.

Option B; Over the interval of (0, 1), b(x) is not positive over the interval (0, 1) and so the statement is wrong.

Option C; Over the interval of (0, 1), b(x) is not positive and increasing and so the statement is wrong.

Option D; Over the interval of (0, 1), b(x) is negative and is also decreasing and so this option is correct.

Answer:

85%

Step-by-step explanation:

Answer:

85% of the balls pitched them.

Step-by-step explanation:

When you want to figure out a percent, you need to take the number of successful outcomes divided by the total number of outcomes. So, in this case, you would take 17/20, which is 0.85. Move the decimal place two times over to the right and you get 85, which is 85%.

There is a linear relationship between the variables x and y. And the line that passes through the origin. Then the correct option is C.

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.

Let the two variables x and y.

Where x is an independent variable and y is the dependent variable that depends on x directly. Then we have

The variable y is directly proportional to the variable x.

y ∝ x

When the proportionality sign is removed a constant k comes into the equation. That is given as

y = kx

There is a linear relationship between the variables x and y.

And the line that passes through the origin.
