Solve for x: (5x + 28)° (4x + 30)°
Answer:
x = 2
Step-by-step explanation:
The 2 angles are vertical and congruent, thus
5x + 28 = 4x + 30 ( subtract 4x from both sides )
x + 28 = 30 ( subtract 28 from both sides )
x = 2

By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.
By definition, it is known that speed equals the ratio of distance and time.
Speed = Distance / Time
Therefore, according to the definition, the last two options are the possible
Let's evaluate the First option:
y = x/96
= 12/96
= 1/8
The table is not fulfilled
Let's evaluate the Second option: (12,8)
y= 2x/3
y= 2*12/3
y = 8
NOW,
(16, 6)
y= 2x/3
2*16/3
the answer will be on a fraction
The table is not fulfilled
Let's evaluate the third option:
y = (3/2) * (1 / x)
x = 12
y = (3/2) * (1/12) = 3/24 = 1/8
The table is not fulfilled
Let's evaluate the fourth option:
y = (96 / x)
x = 12
y = (96/12) = 8
Yes, the table is met.
Option 4 ) y = (96 / x)
By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.

Sally found a wallet while walking down the street the other day and it contained 11 bills in total. The wallet had only $5 bills, $10 bills and $20 bills in it. The total value of all the bills was 115, and the total of the $5 and $10 bills was $75. Define the variables using xyz.
Answer:
x=3
y=6
z=2
Z is the number of $20 bill , y is the number of $ 10 bill and x is the number of $ 5bill
Step-by-step explanation:
Let the number of $5 bills be x, number of$10 bills bey and number of $20 bills be z in it.
Then
5x+ 10y+ 20z= 115------A
5x+10y= 75------B
Putting the values from A into B
75+ 20z= 115
20 z= 115-75
20z =40
z= 40/20 = 2
There were 2 bills of $ 20.
Now we are left with 9 bills which are of $5 and $10
so
x+y=9
or x= 9-y------C
Putting C in B
5(9-y) + 10y = 75
45-5y+10y= 75
45+5y= 75
5y= 75-45
5y= 30
y= 6
So the number of $10 bills are 6.
And the number of $5 bills are 3
simplify the equation and tell whether the equation has one solution, no solution, of infinitely many solutions. 9(x+5) = 20+9x+25
Answer:
Infinite Solution
Step-by-step explanation:
no matter what you put for x you would still get 9x+45=9x+45 if you put x=8 it would equal the same on both sides
The system of equations 9(x + 5) = 20 + 9x + 25 has infiinitely many solutions.
What is the graphical solution of a system of equations?Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given, 9(x + 5) = 20 + 9x + 25.
9x + 45 = 20 + 9x + 25.
9x + 45 = 9x + 45.
So, They are basically the same straight lines coinciding with each other and have infinitely many solutions.

write an equation that goes through the ordered pairs (2,-1) and (4,-6)
Answer:
y = -5/2x +4
Step-by-step explanation:
Find the slope:
m = (y2 - y1) / (x2 - x1)
m = (-6 - (-1)) / (4 - 2)
m = -5 /2
y = mx + b
y = -5/2x + b
Solve for b:
y = -5/2x + b
-1 = (-5/2)(2) + b
-1 = -10/2 + b
-1 = -5 + b
b = 4
y = -5/2x + 4
what is the vertex of the graph function y=4x^2+8x-2
Answer:
vertex = (-1, -6)
Step-by-step explanation:
The function you gave is in the Standard Form : y = aX^2 + bX + c.
So you use the equation x = -b/ 2a to solve for the x coordinate of your vertex.
Based on your question, a =4, b =8 and c = -2.
So you plug that in and get x = -8/2(4). Thus, x value for the vertex is -1.
Now you plug -1 into your original equation to find your y value.
y = 4 (-1)^2 + 8 (-1) -2
So y = -6. Thus, your vertex is at pt (-1, -6)

The path of water from a hose on a fire tugboat can be approximated by the equation y = −0.0045x2 + 1.15x + 10, where y is the height, in feet, of the water above the ocean when the water is x feet from the tugboat. When the water from the hose is 3 feet above the ocean, at what distance from the tugboat is it? Round answer to nearest hundredth.
Answer:
x = 261.50 ft
Step-by-step explanation:
From the question, we want to calculate the distance from the tugboat given the height of the hose above the ocean
This means y is 3 and we want to find x
Substitute value for y
3 = -0.0045x^2 + 1.15x + 10
3 + 0.0045x^2 - 1.15x - 10 = 0
That will be;
0.0045x^2 - 1.15x - 7 = 0
we can use the quadratic formula here;
a = 0.0045
b = -1.15
c = -7
Mathematically;
x = -b ± √b^2 - 4ac/2a
Thus we have;
x = 1.15 ± √(-1.15)^2 - 4(0.0045)(-7)/2(0.0045)
We have;
x = 1.15 ± 1.2035/0.009
x = (1.15+ 1.2035)/0.009
we ignore the negative since distance cannot be negative
x = 261.50 ft

First, you have to move the decimal point before you divide like normally. You need to move it so that the left number is a whole number.
So, 6.39/0.9 would turn into 63.9/9.
12.75/2.5 would turn into 127.5/25.
You just move the decimal how ever many times to the right to make it a whole number. In this case, it is 1 decimal place.
