Brody is older than Nathan. Their ages are consecutive odd integers. Find Brody's age if the sum of Brody's age and 5 times Nathan's age is 80.
Based on the information given, Brody is older than Nathan, then;
Brody's age is 15 years.
What are algebraic expressions?Algebraic expressions are expressions comprising of variables, terms, factors, constants, and coefficients.
They are also made up of mathematical operations like addition, subtraction, multiplication, parenthesis, bracket, division, etc
From the information given, we have that
Nathan's age = xBrody's age = x + 2It is represented thus;
5x + x + 2 = 80
collect like terms
6x = 80 - 2
Subtract like terms
6x = 78
Make 'x' the subject of formula
Divide both sides by 6
x = 78/6
x = 13
But we have that;
Brody's age = x + 2
Substitute the value of x
Brody's age = 13 + 2
Brody's age = 15 years
Thus, Brody's age is 15 years.

The sum of two numbers is 172. The first is 8 less than 5 times the second. Find the first number.
Question content area top Part 1 Find the midpoint of the line segment joining points A and B. A(8,-5) B(2,1) ;
Answer:
[tex](5,\, -2)[/tex].
Step-by-step explanation:
For a line segment in a plane, the [tex]x[/tex]-coordinates of the midpoint is the average of the [tex]x\![/tex]-coordinates of the endpoints. Likewise, the [tex]y[/tex]-coordinates of the midpoint is the average of the [tex]y\![/tex] coordinates of the endpoints.
For example, the midpoint of the line segment joining [tex](x_{a},\, y_{a})[/tex] and [tex](x_{b},\, y_{b})[/tex] is:
[tex]\begin{aligned} \left(\frac{x_{a} + x_{b}}{2},\, \frac{y_{a} + y_{b}}{2}\right)\end{aligned}[/tex].
In this question, [tex]x_{a} = 8[/tex], [tex]x_{b} = 2[/tex], [tex]y_{a} = (-5)[/tex], [tex]y_{b} = 1[/tex]. Thus, the midpoint of the line segment joining the two points would be:
[tex]\begin{aligned} \left(\frac{8 + 2}{2},\, \frac{(-5) + 1}{2}\right)\end{aligned}[/tex].
Simplify to obtain:
[tex]\begin{aligned} \left(5,\, -2\right)\end{aligned}[/tex].
Hence, the midpoint of the line segment joining [tex](8,\, -5)[/tex] and [tex](2,\, 1)[/tex] would be [tex](5,\, -2)[/tex].

We get the composite function for the relationship between area and time as A = π (16t + r )².
We are given that, the wave travels at a rate of 16 feet / sec when George jumps off a tire swing in the circular pond.
So, this means that the radius of the wave increases by 16 feet in every second.
Now, we know that, the area of circle is given by:
A = π r²
Now, r increases by 16 feet every second.
So, the composite function will become:
A = π (16t + r )²
where 16 t represents the increase in area in t seconds.
Therefore, we get the composite function for the relationship between area and time as A = π (16t + r )².

For each set of values, determine which is greater without using a calculator. √3+ √11 or 5
√3+ √11 is greater than 5 .
We first assume that √3+ √11 is greater than 5. Then we check if our assumption is correct.
So suppose that √3+ √11 > 5
Squaring on both sides and using the identity [tex](a+b)^2=a^2+b^2+2ab[/tex],
⇒ 14 + 2√33 > 25
Subtracting 14 from both sides,
⇒ 2√33 > 11

For each direct variation, find the constant of variation. Then find the value of y when x=-3 .
y=-16 when x=7
For the direct variation y = (-3/8) when x = (-2/3), the value of y is y = 1(11/16).
What do we mean by direct variation?To give the reader a hint, direct variation equations use the same phrase. The phrase is either "directly proportional" or "directly varies." The area of a square, for example, varies directly from the square of its side. If y varies directly as x and y = 6 when x = 2, the constant of variation is k = 3. As a result, the equation for this direct variation is y = 3x.So,
[tex]x \propto y[/tex] or [tex]x=k \cdot y[/tex] or [tex]k=\frac{x}{y}[/tex] or [tex]k=\frac{-\frac{2}{3}}{-\frac{3}{8}}=\frac{16}{9}[/tex], k is constant.The equation of variation is: [tex]\frac{x}{y}=\frac{16}{9} ; x=3 ; y=?[/tex]
[tex]\frac{3}{y}=\frac{16}{9}[/tex] or [tex]y=\frac{9 \cdot 3}{16}=\frac{27}{16}=1 \frac{11}{16}[/tex]Therefore, for the direct variation y = (-3/8) when x = (-2/3), the value of y is y = 1(11/16).

Therese is in Italy and has dinner with her friends. Her meal cost her 43 Euros (€). The conversion rate is 1€ = $1.14 How much did Therese pay for her
meal in dollars?
Therese paid
Answer:
49.02
Step-by-step explanation:
Ok, so this is a conversion problem and it wants you to get 45 euros to whatever amount of dollars that equals. So first, you need to get the conversion rate.
1 euro/1.14 dollars
Now, plug in the 43 Euros to the front of the conversion rate
43 euros (1 euro/1.14 dollars)
You want what you start with on the bottom of the conversion factor, so switch the rate around
43 euros (1.14 dollars/1 euro)
Then, multiply what is on top, then divide by what is on the bottom.
49.02 dollars/1=49.02 dollars
The euros go away because they cancelled out.

Rationalize the denominator of each expression. Assume that all variables are positive. √3 x / 2y
After rationalizing the denominator for the expression √3 x / 2y, we get that the result is [√6xy)] / 2y.
The removal of a radical or imaginary number from the denominator of an algebraic fraction is referred to as rationalization. That is, eliminate the radicals from a fraction to leave only a rational integer in the denominator.
Rationalizing the divisor suggests that you get eliminate the novel within the divisor.
by the rules of radicals, We can rephrase this as √(5x) / √(2y)
The expression will then be multiplied by √(2y) / √(2y). Keep in mind that this results in 1, and multiplying this by the first expression has no effect on the original issue.
On multiplying we get-
[√(3x) * √(2y)] / [√(2y) * √(2y)]

2. cosθ = ₋5/√29
3. tanθ = 2/5
4. cotθ = 5/2
5. secθ = ₋√29/5
6. cosecθ = ₋√29/2
Given, the point is (-5 , -2).
The angle is in the 3rd quadrant.
Find the length of the hypotenuse by using the Pythagorean Theorem.
c² = a² + b²
the length of side (a) = -5
the length of side (b) = -2
therefore, c² = (⁻5)² + (₋2)²
c² = 25 + 4
c² = 29

c = 5.39
Now, values for the six trigonometric functions are:
sinθ = perpendicular/ base = b/c = ₋2/√29
cosθ = Adjacent/hypotenuse = a/c = ₋5/√29
tanθ = perpendicular/ adjacent = b/a = ₋2/₋5 = 2/5
cosecθ = 1/sinθ = 1/₋2/√29 = ₋√29/2
secθ = 1/cosθ = 1/₋5/√29 = ₋√29/5

Question 4(Multiple Choice Worth 1 points) (01.06 LC) Solve y = x + 4 for x.
Answer:
x = y - 4
Step-by-step explanation:
"Solve for x" means to get the x all by itself on one side of the equation.
We start with:
y = x + 4
Subtract 4 from both sides of the equation.
y - 4 = x
This is the same as
x = y - 4
Now it is "solved for x" because the equation shows what x is equal to.
given f(x) = x² + 5x +6 and g(x) = x +2, find (f ◦ g) (x)
The composition of f(x) and g(x) gives:
(f ◦ g) (x) = x² + 9x + 20
How to find the composition of functions?Here we have the two functions:
f(x) = x² + 5x +6
g(x) = x +2
And we want to find the composition:
(f ◦ g) (x)
The composition means that we need to evaluate f(x) in g(x), so we get:
(f ◦ g) (x) = f( g(x))
Then we will get:
(f ◦ g) (x) = g(x)² + 5*g(x) +6
Now, replacing g(x) we get:
(f ◦ g) (x) = (x + 2)² + 5*(x + 2) + 6
Expanding that, we get:
(x + 2)² + 5*(x + 2) + 6 = x² + 4x + 4 + 5x + 10 + 6 = x² + 9x + 20
(f ◦ g) (x) = x² + 9x + 20
