• Which function is best represented by this graph?
A y = 1/4x+8
B y = 1/4x -2
C y = 4x -2
D y = 4x + 8
Answers
Answer:
B y=1/4x-2
Step-by-step explanation:
in y = mx + b
the b is the y intercept. this is where the line cuts through the y axis. you can see that it is going through the y axis at -2.
now look for your slope. I use rose over run. you can see that the line intersects at (4,-1)
"rise" is how far up or down to your next point."run" is how far left your right your next point is. in this case, the next point is 1 up and 4 to the right of a point. this translates to 1/4. this is a positive slope because your line goes upwards from left to right.

C. -3/4
Step-by-step explanation:
Answer:
-3/4
Step-by-step explanation:
You could identify two points and used the slope formula given two points.
OR
You can just count from one point to another.
First step: Identify two points where the line crosses nicely.
I see one at the y-intercept (0,1) and another at (4,-2). So starting at the y-intercept, how much do we need to travel down to get to (4,-2). Hopefully you say down 3, so the rise is -3. Now how much to the right after traveling down 3 from (0,1) to we need to travel to get to (4,-2) . Count the spaces...4 units right so the run is 4.
The slope is -3/4
which equation can be used to solve x in the diagram??
a) 13x - 5x = 180
b) 5x + 13x = 90
c) 5x + 13x = 180
d) 5x = 13x
no links pls!!
Answers
Step-by-step explanation:
C) 5x + 13x = 180°
Because, the angles in the diagram add up to 180° because it's a straight angle
So, the sum of both of them will give 180
So option (C) is right

A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet. What is the price for one square yard of carpet?
Answers
Answer:one yard costs $15 (x=15)
Step-by-step explanation:
300-60=240. So, 16 yards=$240
16x=240
240/16=15
X=15 (one yard costs $15)
The price for one square yard of carpet is $15.
Given that,
A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet.Based on the above information, the calculation is as follows:
[tex]= (\$300 - \$60) \div 16[/tex]

Solve y=f(x) for x. Then find the input when the output is −3. f(x)=−7x−2 x= The input is when the output is −3.
Answers
Answer:
The input is 1/7
Step-by-step explanation:
If y =f(x)
Given that f(x) = -7x -2, then y = -7x-2
x is the input
y is the output
Given the output y = -3, we are to find the input value x
Recall that y = -7x-2
On substituting the value of y into the equation
-3 = -7x - 2
-7x = -3+2
-7x = -1
x = -1/-7
x = 1/7
Hence the input is 1/7

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?
Answers
Answer:
The missing angle is 41 degrees
Step-by-step explanation:
First of all, a triangle is measured at 180 degrees in total
To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.
47+92=139 degrees
Next just subtract 139 from 180 to get your answer.
180-139=41 degrees
The answer is 41 degrees

Answer: -7/10, -0.35, 1/5, 0.95
Step-by-step explanation:
-7/10 = -.7
1/5 = 0.2
Answer:
From least to greatest, the correct order is [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.
Step-by-step explanation:
Since all negative numbers are smaller than positive, you immediately know that [tex]-\frac{7}{10}[/tex] and -0.35 are smaller than [tex]\frac{1}{5}[/tex] and 0.95. The greater the absolute value of a negative number is, the smaller that number is. Because [tex]-\frac{7}{10}[/tex] is -0.7, which has a greater absolute value than -0.35, this means [tex]-\frac{7}{10}[/tex] is the smallest number, and -0.35 is the second smallest number. Since [tex]\frac{1}{5}[/tex] is 0.2 which is smaller than 0.95, the correct order from least to greatest would be [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

y = -2x^3 + 5x^2 + x - 2
Answers
Answer:
its one solution
Step-by-step explanation:
This system of equations have a unique solution.
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
The system of equations are
y = -1/3x + 7 ------- (1)
y = -2x^3 + 5x^2 + x - 2 ------- (2)
Equation 1 is a linear equation and equation 2 is a polynomial equation.
So graph these two equations to find the solution.
The graph below shows the plotting of these two equations and
solution of these equations.
From the graph, it is clearly seen that this system of equation has only one solution.
Hence we can conclude that this system of equations have a unique solution.
