It's a Quadratic that doesn't have any real roots as the parabola doesn't cross the x-axis.
For graphing:
If you're familiar with the parabola of y=x^2, then you could graph that but just translate it upwards by +4 on the y such that f(x)+4 will be equal to it.
If you aren't, then we know the y-intercept is 4, and that's also the point of the minimum point of the curve. If I were you, I'd write a table of some of the integer values:
x y
-2 8
-1 5
0 4
1 5
2 8
The value of y is the same for x and -x as anything squared is positive.This means that there is a line of symmetry in the y-axis.
This then makes it much easier to graph, simply place these points on the graph and make sure the curve is exponential. This means the gradient (steepness) gets greater the bigger the value of x.

Step-by-step explanation:
A quotient is a fraction.
A sum is addition.
A variable is an unknown number shown by using a letter.
Therefore, the answers for quotient and variable in this picture should be switched. However, the negative sign has to be included, so the quotient should be a -9/y.

Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : y-(3*x-3)=0
Step 1:
Equation of a Straight Line
Solve y-3x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-3x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -3/1 = -3.00000
Calculate the X-Intercept :
When y = 0 the value of x is 1/1 Our line therefore "cuts" the x axis at x= 1.00000
x-intercept = 3/3 = 1
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - (-3.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 6.000/2.000 = 3.000
Geometric figure: Straight Line
Slope = 6.000/2.000 = 3.000
x-intercept = 3/3 = 1
y-intercept = -3/1 = -3.00000
2)
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(4/3*x+3)=0
Step 1:
Simplify 4/3
Equation at the end of step 1:
y - ((4/3 • x) + 3) = 0
Step 2: Rewriting the whole as an Equivalent Fraction
Adding a whole to a fraction
Rewrite the whole as a fraction using 3 as the denominator :
3 = 3/1 = 3 · 3/3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4x + 3 · 3/3 = 4x+9/3
Equation at the end of step 2:
y - (4x+9)/3=0
Step 3:
Rewriting the whole as an Equivalent Fraction :
Subtracting a fraction from a whole
Rewrite the whole as a fraction using 3 as the denominator :
y = y/1 = y · 3/3
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
y • 3 - ((4x+9)) 3y - 4x - 9
———————————————— = ———————————
3 3
Equation at the end of step

:
3y - 4x - 9

When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3y-4x-9
——————— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3y-4x-9 = 0
Equation of a Straight Line
4.2 Solve 3y-4x-9 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3y-4x-9 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3/1 so this line "cuts" the y axis at y= 3.00000
y-intercept = 9/3 = 3
Calculate the X-Intercept :
When y = 0 the value of x is 9/-4 Our line therefore "cuts" the x axis at x=-2.25000
x-intercept = 9/-4 = -2.25000
Calculate the Slope :
Slope = 2.667/2.000 = 1.333
Geometric figure: Straight Line
Slope = 2.667/2.000 = 1.333
x-intercept = 9/-4 = -2.25000
y-intercept = 9/3 = 3
Evaluate the expression.
{[(20−32)÷(−6)]2−11}÷(−7)
What is the value of the expression?
Enter your answer in the box.
The value of the expression is 1
From the question,
We are to evaluate the value of the expression {[(20−32)÷(−6)]2−11}÷(−7)
To do this, we will clear the brackets one after the other.
The expression can be simplified as shown below:
{[(20−32)÷(−6)]2−11}÷(−7)
{[(-12)÷(−6)]2−11}÷(−7)
Then, we get
{[2]2−11}÷(−7)
{4−11}÷(−7)
{-7}÷(−7)
-7 ÷ -7
= 1
Hence, the value of the expression is 1

One month Dante rented 2 movies and 3 video games for a total of$22 . The next month he rented 4 movies and 8 video games for a total of$57 . Find the rental cost for each movie and each video game.
Answer:
x = $1.25; y = $6.50
Step-by-step explanation:
Let x be the cost of movies and y be cost of video games.
Month 1 has 2x+3y = 22
So here x = (22-3y)/2 and y = (22-2x)/3
Month 2 has 4x+8y =57
Here x = (57-8y)/4 and y = (57-4x)/8
Now you have two options: Find the y or the x. I will demo the x and you can try the y if you wish.
(22-2x)/3 = (57-4x)/8
176-16x = 171-12x
-4x = -5
x = 1.25
Now with the x found, you plug it into either of the y equations to figure out the other variable.
y = (22-2(1.25))/3
y = 6.5
And to double check:
y = (57-4(1.25))/8
y = 6.5

Write the slope intercept form of the equation for f the line through the given points
Answer:
y = -2x - 4
Step-by-step explanation:
First, I'll find the slope by subtracting the y-values and x-values of each point from each other, as shown below:
(-2 - (-4))/(-1 - 0) = 2/-1 = -2
We already have the y=intercept: (0, -4). From this, we can write a y = mx + b (slope intercept form) equation, with m being our slope and b being our y-intercept. It looks like y = -2x - 4.
