solve each system of inequalities and indicate any three solutions. x-0.8 <0, -5x<10

Answers

The three solutions of the inequalities are x < 0 , x <  0.8 , x< -2

What are inequalities?

Inequalities are defined as mathematical expressions in which both sides are not made equal to each other.

Given the inequalities;

x-0.8 <0-5x<10

Let's solve for the value of x

x - 0.8 < 0

Make 'x' the subject

x < 0 + 0. 8

x < 0. 8

-5x < 10

Make 'x' the subject by dividing both sides by - 5

-5x/ 5 < 10/ -5

x < -2

Thus, the three solutions of the inequalities are x < 0 , x <  0.8 , x< -2

Athena's credit card has an APR of 32.99%. If her current monthly balance, before interest, is $2,719.83, what amount will she be charged for interest?

Answers

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned. Athena's will be charged $74.77 for interest.

What is Interest Rate?

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.

Given,

Athena's credit card has an APR of 32.99%.

We need to convert the percentage to decimal.

32.99%=32.99/100

=0.3299

The amount will she be charged for interest is

=(2719.83*0.3299)/12

=897.27/12

how to turn y=3x+45 into ax+by=c form

Answers

The given equation y = 3x + 45 in form ax+by=c is 3x - y = - 45.

What are linear equations?Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is fairly simple (x and y). When attempting to solve systems of two linear equations, this form is also very helpful. A linear equation has the slope-intercept form y = MX + b. Variables in the equation are x and y. When x is 0, the numbers m and b provide the line's slope (m) and the value of y(b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.

So,  y=3x+45 into ax+by=c form:

y = 3x + 45 ⇒ Bring y to the other side of the equation and bring 45 to the opposite side of the equation as: y = 3x + 45 ⇒ 3x - y = - 45

Therefore, the given equation in form ax+by=c is 3x - y = - 45.

Which statement is true about the function f(x) = 8x^3?

The function is even because f(–x) = f(x).
The function is odd because f(–x) = f(x).
The function is even because f(–x) = –f(x).
The function is odd because f(–x) = –f(x).

Answers

The function f(x) = 8x³ satisfies the condition f(-x) = -f(x) and is odd. D.

To determine whether the function f(x) = 8x³ is even or odd, we need to analyze the symmetry of the function with respect to the y-axis and the origin.

Even function:

If a function is even, it satisfies the condition f(-x) = f(x), meaning that the function is symmetric with respect to the y-axis.

Odd function:

If a function is odd, it satisfies the condition f(-x) = -f(x), meaning that the function is symmetric with respect to the origin.

Now, let's analyze the given function, f(x) = 8x³:

Testing for evenness:

If we substitute -x for x in the function, we have f(-x) = 8(-x)³

= -8x³.

This is not equal to f(x) = 8x³.

The function f(x) = 8x³ is not even.

Testing for oddness:

If we substitute -x for x in the function, we have f(-x) = 8(-x)³

= -8x³.

This is equal to -f(x) = -8x³.

The function is odd because f(–x) = –f(x).

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

From the given information:

The larger of two numbers is 10 less than the smaller number. The sum of the two numbers is 50.

Then

Let the first number be x and the second number y

Then

y = x -10

And

x+y = 50

Then

Substitute the value then

x+x-10 = 50

2x = 50+10

Estimate the probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws.

Answers

The probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384

What is probability?

Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.

Now it is given that,

The proportion of free throws the player makes, p = 80% = 0.8

The number of throws, n = 3

The throws the player makes, r = 2

Since the probability is given as,

P(r) = nCr x p^r x (1 - p)^(n-r)

So, the probability that an NBA player makes 2 of his next 3 free throws

Putting the values we get,

P(2) = ³C₂ x (0.8)^2 x (1 - 0.8)^(3-2)

Solving we get,

P(2) = 3 x 0.64 x (0.2)^(1)

Thus we get,

P(2) = 3 x 0.64 x 0.2

Multiplying we get,

P(2) = 0.384

this is the required probability that an NBA player makes 2 of his next 3 free throws.

Thus, the probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384

If the sum of ages is X and Y and the ratio of their ages is p : q respectively, then you can determine the age of Y by using the formula shown below:

Age of Y = Ratio of Y / Sum of ratios x sum of ages

Age of Y = q/ (p +q) x A

Weight average = ( (6 x 2) + (9 x 2) + (15 x 1) ) / (2 + 2 + 1)
