find the x-intercept
Answer:
(95/12,0)
Step-by-step explanation:
Answer:
(7.916, 0)
Step-by-step explanation:
In order to find the X-intercept, let y=0
12x + 5(0) = 95
12x = 95
95/12x = 7.91666...
Therefore, the x intercept is (7.916, 0)

Which equation produces the values in the table?
O y= 4x
O y=4+x
O y=1/4x
Oy=4 - x
Answer:
Step-by-step explanation: It’s C thank me later
The equation produces the values in the table is y = x/4
What is an equation?Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.
For example, 2x – 5 = 13.
Given is table (attached) we need to determine an equation that produces the values in the table,
So, seeing the value it is much that the value of x are the 4 times of the values of y,
So, we can write,
4y = x
or, y = x/4
Hence, the equation produces the values in the table is y = x/4

I hate math
First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)
Your equation after should be
5x + 6x - 12 - 8x + 24
Next would be addition, don't forget it's always left to right.
11x - 12 - 8x + 24
Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).
11x - 8x + 12
Next, subtract the two remaining x values.
3x + 12
And there you have it. Easy peasy.
If the case is trying to find x, just solve it like this.
3x = -12
x = 4

Answer:
The answer is 14 minutes
Step-by-step explanation:
Subtract your total and divide what you have left. $20 - $18.04 = $1.96
You spent a total of $1.96
Divide that by 0.14 how much per minute and you get 14 minutes.
If the 8 men on a construction crew make up 40% of the entire crew, how many people are in
the crew?
Answer:
20
Step-by-step explanation:
Since 40% of the crew are men, which means n.40=8 n=8/.40 n=20 total number of crew 20 - 8=12 are women.
The number of people in the crew is 20.
Let the number of people in the crew be represented by x.
Therefore, 40% of x will be 8. This can then be written as:
40% of x = 8
40/100 × x = 8
0.4 × x = 8
0.4x = 8
Divide both side by 0.4
0.4x/0.4 = 8/0.4
x = 20
Therefore, the number of people in the crew is 20.

[50 Points] The function [tex]y = 4.2\sqrt{0.28 x - 1}[/tex] models the annual number of visitors to an amusement park, where y is the number of visitors in millions and x is the number of years since 1975. Find the first year in which the amusement park had 12 million visitors?
Answer:
In 2008.
Step-by-step explanation:
The function:
[tex]y=4.2\sqrt{0.28x-1}[/tex]
Models the annual number of visitors to an amusement park, where y is the number of visitors (in millions) and x is the number of years since 1975.
We want to determine the first year in which the amusement park had 12 million visitors.
So, we will set y equal to 12 and solve for x. This yields:
[tex]12=4.2\sqrt{0.28x-1}[/tex]
By dividing both sides by 4.2, we acquire:
[tex]\displaystyle \frac{12}{4.2}=\frac{120}{42}=\frac{20}{7}=\sqrt{0.28x-1}[/tex]
And by squaring both sides:
[tex]\displaystyle \frac{400}{49}=0.28x-1[/tex]
Adding 1 to both sides produces:
[tex]\displaystyle \frac{400}{49}+1=\frac{449}{49}=0.28x[/tex]
And finally, dividing both sides by 0.28 gives us the approximation:
[tex]\displaystyle x=\frac{449}{49}\cdot \frac{1}{.28}=\frac{11225}{343}\approx32.72\approx33[/tex]
So, 33 years after 1975, the amusement park will have 12 million annual visitors.
Therefore, the first year in which the amusement park will have 12 million annual visitors is in the year 2008.

Answer:
x = 4.99°
Step-by-step explanation:
Reference angle = x
Opposite side to x = 20 cm
Hypotenuse = 230 cm
Applying trigonometric ratio formula, we would have the following equation:
[tex] sin(x) = \frac{Opp}{Hyp} [/tex]
Plug in the values
[tex] sin(x) = \frac{20}{230} [/tex]
[tex] x = sin^{-1}(\frac{20}{230}) [/tex]
x = 4.99° (approximated to nearest hundredth)
What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the solution. Thank you!
Answer:
EF = 8.8 cm
Step-by-step explanation:
In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/DE/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/DF/^{2}[/tex]
[tex]/16.2/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/13.6/^{2}[/tex]
262.44 = [tex]/EF/^{2}[/tex] + 184.96
[tex]/EF/^{2}[/tex] = 262.44 - 184.96
= 77.48
EF = [tex]\sqrt{77.48}[/tex]
= 8.8023
EF = 8.8 cm
The length of side EF is 8.8 cm.

I am placing steps for each point given
1. Isolate x in the first equation:
First equation is:
x+3y=7
Isolating x:
x=7-3y
2. Substitute the value for x into the second equation:
Second equation is:

A line passes through the points (-1, -8) and (3, 12). Compute the slope of
the line. Show your steps. *
Your answer
This is a required question
A line passes through the points (-1, -8) and (3, 12). Write the equation for
the line that passes through these points in the form y=mx + b. (Hint: you
already computed m in the previous problem.) *
Answer:
y = 5x - 3
Step-by-step explanation:
The Slope of a Line
Suppose it's given a line that passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The equation of the line in slope-intercept form is:
y=mx+b
Where:
m = slope
b = y-intercept.
We are given the points (-1,-8) and (3,12). Compute the slope:
[tex]\displaystyle m=\frac{12+8}{3+1}=\frac{20}{4}=5[/tex]
The equation of the line now has one known value:
y = 5x + b
Let's use the point (3,12) to find the value of b:
12 = 5(3) + b = 15 + b
Solving for b:
b = 12 - 15 = -3
The required equation of the line is:
y = 5x - 3
