Answer: x = 61 and y = 29
Step-by-step explanation: In this problem, notice that we
have a transversal that intersects two coplanar lines at different points.
Let's start by finding the value of y.
In the diagram, 2y and 58 are corresponding angles and if two
parallel lines are cut by a trans. corr. <'s must be congruent.
So we can setup the equation 2y = 58.
Solving from here, we find that y = 29.
Now, notice that 58 and 2x form a straight angle or a linear pair.
When two angles form a straight angle, they are supplementary.
So we can setup the equation 2x + 58 = 180.
Solving from here, we find that x = 61.

Answers
Answer:
The answer is 36 adults and 88 children.
Step-by-step explanation:
The two equations are:
x+y=124 and 5x+3y=444
Using substitution method:
5x+3(124+x)=444
5x+372-3x=444
2x=72
x=36
5(36)+3y=444
180+3y=444
3y=264

7) (-7) + (-10) – 5 +2
here, we will use the BODMAS rule, the addition and subtraction will go from left to right.
= -7 -10 -5 + 2
= -17 -5 + 2
= -22 + 2
= -20
8) (-9) + 4 + (-8) – (-7)
= -9 +4 -8 +7
= -5 -8 +7
= -13 + 7
= -6
9) (-6) – (2 x 4) – (-1)
= -6 - 8 +1
= -12 + 1
= -11
10) (-8) + (-4 ÷ -4) – 8
= -8 -4/ (-4) - 8
= -8 +1 -8
= -7 -8
= -15
Therefore, the value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.

Explanation:
We'll use the zero product property to solve.
[tex]3(x^2+5)^2(x^2-25)^3(x-8)^4 = 0\\\\(x^2+5)^2=0 \text{ or } (x^2-25)^3=0 \text{ or } (x-8)^4 = 0\\\\x^2+5=0 \text{ or } x^2-25=0 \text{ or } x-8 = 0\\\\x^2=-5 \text{ or } x^2=25 \text{ or } x = 8\\\\x=\pm\sqrt{-5} \text{ or } x=\pm\sqrt{25} \text{ or } x = 8\\\\x=\pm i\sqrt{5} \text{ or } x=\pm 5 \text{ or } x = 8\\\\[/tex]
where [tex]i = \sqrt{-1}[/tex]
----------------------
The notation [tex]x=\pm i\sqrt{5}[/tex] breaks up into [tex]x=i\sqrt{5} \text{ or } x=-i\sqrt{5}[/tex]. The multiplicity of these two roots is 2 as it's the exponent of the factor [tex](x^2+5)^2[/tex]. Focus on the outermost exponent.
The notation [tex]x = \pm 5[/tex] becomes [tex]x = 5 \text{ or } x = -5[/tex]. The multiplicity of these two roots is 3 since it's the outermost exponent of the factor [tex](x^2-25)^3[/tex]
And finally, the multiplicity of the root x = 8 is 4 because it is the outermost exponent of the factor [tex](x-8)^4[/tex]

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-x + 5y = -4
4x + 3y = 16
Step 2: Rewrite systems
x = 5y + 4
4x + 3y = 16
Step 3: Solve for y
Substitute in x: 4(5y + 4) + 3y = 16Distribute 4: 20y + 16 + 3y = 16Combine like terms: 23y + 16 = 16Subtract 16 on both sides: 23y = 0Divide 23 on both sides: y = 0Step 4: Solve for x
Define: 4x + 3y = 16Substitute in y: 4x + 3(0) = 16Multiply: 4x = 16Isolate x: x = 4And we have our final answer!

2x = x +5 . . . . . . . . . add 1, simplify

given function of f(x) = 2x - 1 and fg(x) = 10x + 3, find the function of g(x)
Answers
Answer:
The function of g(x) = 5x + 2
Step-by-step explanation:
Let us use the composite function to solve the question
∵ f(x) = 2x - 1
∵ f(g(x)) = 10x + 3
→ f(g(x)) means substitute x in f(x) by g(x)
∴ f(g(x)) = 2[g(x)] - 1
→ Equate the two right sides of f(g(x))
∴ 2[g(x)] - 1 = 10x + 3
→ Add 1 to both sides
∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1
∴ 2[g(x)] = 10x + 4
→ Divide each term into both sides by 2
∵ [tex]\frac{2[g(x)]}{2}[/tex] = [tex]\frac{10x}{2}[/tex] + [tex]\frac{4}{2}[/tex]
∴ g(x) = 5x + 2
∴ The function of g(x) = 5x + 2
a pump fills a pool at a constant rate at the end of 9 minutes it has filled 1 gallon of water which table represents the relationship between the number of minutes and the number of gallons of water in the pool
Answers
Answer:
D
Step-by-step explanation:
The rate at which the pool is filled is 1 gallon per 9 minutes. If you divide all the numbers of minutes in the left side of the table with the number of gallons on the right you get 9 minutes per gallon for each of them so they follow the rate.
