Answer:
4a-b-c
Step-by-step explanation:
we first look at the letters of each number. if there is only a letter, there is an imaginary 1 in front of it. we need to make sure that we add the numbers that have the exact same letters because they are known as like terms. we cannot add 6a and 4b because the letters are different and they are known as unlike terms. When we add numbers with the same letter ONLY the number changes

Answer:
Therefore, x is 1 and 2.
Step-by-step explanation:
As you plot both equations on the same graph, you will get something like this, shown in the graph.
Then, you have to find the x solutions where they intersect.
So, both equations intersect at x = 1 and 2.

To find the equation of line take any two points on graph,
Point A = (0,3) = (X1,Y1)
Point B = (3,0) = (X2,Y2)
Y intercept is = 3,
Now find the slope of line using two point formula,
[tex]Slope = \frac{Y2-Y1}{X2-X1} \\ \
Slope = \frac{3-0}{0-3} = -1[/tex]
Equation of the line in standard form is,
[tex]Y - Y1 = m(X - X1)[/tex]
where m is the slope of line!
Now substituting Y1, m, X in above equation!
[tex]Y - Y1 = m(X - X1) \\ Y - 3 \: = - 1(X - \: 0) \\ Y - 3 = - X \\
X + Y = 3 \\
Y = 3 - X[/tex]
The equation of line in Slope intercept form,

Which equation describes the graph?
Answer:
y=(-3/5)x + 5
Step-by-step explanation:
Looking at the graph, we can see two clear points; (0,5) and (5, 2). We know that the y-intercept is (0,5) so the b value of the standard form of a line, y=mx+b, is 5. Since we know two points, we can figure out the slope. So, the slope is (5-2)/(0-5) = 3/-5. Therefore the equation of this line is y=(-3/5)x+5. We can check this answer by plugging in points.

Consider the line 7x+5y=−2.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer: slope of a line perpendicular is [tex]\frac{5}{7}[/tex]; slope of a line parallel to this line is [tex]-\frac{7}{5}[/tex].
Step-by-step explanation:
Rewrite the line in y = mx + b form, where m is slope and b is y-intercept.
7x + 5y = -2
5y = -7x -2
y = [tex]-\frac{7}{5}[/tex]x - [tex]\frac{2}{5}[/tex]
The product of two slope of perpendicular line is -1.
Let x be the other line that perpendicular line with the line 7x + 5y = -2.
（[tex]-\frac{7}{5}[/tex])x = -1
x = [tex]\frac{5}{7}[/tex]
The slope of a line parallel to this line is the same, which is [tex]-\frac{7}{5}[/tex].

Each of 5 gift bags contains x pencils. Tyler adds 3 more pencils to each bag. Altogether, the gift bags contain 20 pencils.
Write an equation for the story. (use "X")
what is the reason for multiplication in the story?
Explanation:
Each of the five bags contain x pencils, where x is a placeholder for a positive whole number.
This means Tyler starts off with 5x pencils
He then adds 3 pencils per bag, so 3*5 = 15 extra pencils, to get the expression 5x+15. We're told the new grand total is 20 pencils.
Therefore, the equation for this story problem is 5x+15 = 20
The reason for the multiplication is because we have the same number of pencils per bag. So we're adding multiple groups together, or using multiplication to do a shortcut.
eg: instead of 5+5+5 = 15 we can do 5*3 = 15

We're given:
The popcorn is 120 calories per serving120 calories is 25% fewer calories than original popcornWe must find the calorie count per serving of the original popcornDetermine VariablesLet x equal the calorie count per serving of the original popcorn.
Create an EquationThe light popcorn has a calorie count of 120, which is 25% fewer calories than regular popcorn. This means that 75% of the calorie count of regular popcorn is equal to that of the light popcorn:
[tex]x*0.75=120[/tex]
Solve the Equation[tex]x*0.75=120[/tex]
⇒ Divide both sides by 0.75:
[tex]\dfrac{x*0.75}{0.75}=\dfrac{120}{0.75}\\\\x=160[/tex]
AnswerTherefore, each serving of regular popcorn has 160 calories.

= 4.05
Step-by-step explanation:
81/20 is the smallest it gets as a fraction I believe
and A. should be 5/4 if i'm not mistaken
Answer:
a) 1 1/4 or b) 4 1/20
Step-by-step explanation:
a) This one is the easier of the two. 7/8+3/8= 10/8 ---» 1 2/8 and 2/8 is 1/4. So 1 1/4.
b) This one is a bit more tricky. You need to find a common denominator between the two, in this case we can use 20.
9/5 ---» 36/20 and 9/4 ----» 45/20.
Do some adding and you get 81/20 ---» 4 1/20.

The equation of the graph of the polynomials is f ( x ) = x² ( x - a )⁵ ( x - b )
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x² ( x - a )⁵ ( x - b )
From the graph of the polynomial , we can see that
The critical points of the function f(x) = x² ( x - a )⁵ ( x - b ) are x = 0, x = a, x = b, and x = (7a + 5b)/3
Hence , the function is f ( x ) = x² ( x - a )⁵ ( x - b )

If an exponential model has a 9% decay rate,
what multiplier would be used in the function
model?
0.9 1.09
1.9 0.91
=====================================================
Explanation:
If you lose 9% of a substance, then you keep the remaining 91% because 100% - 9% = 91%. Or you can think of it as 91% + 9% = 100%
Then we convert 91% to decimal form to get 0.91
-----------
Or you can do the steps like this:
9% = 0.09
1 - 0.09 = 0.91

16. Marique is making a large table in the shape of a trapezoid. She needs
to calculate the area of the table. The longest side of the table is twice
as long as the table's width. Find the area of the table by decomposing
the trapezoid into familiar shapes. Show your work
Given that the length of the table is twice the width which is 1.25 m. and
the difference in the parallel side is 1 m., the area of the table is 2.5 m².
How can the area of the table be calculated?The possible table dimensions are;
Width of the table = 1.25 m
Width of the table = The height of the trapezoid
The difference in length between the parallel sides = 2 × 0.5 m = 1 m
Longest side of the table is a parallel side of the trapezoid
Given;
Length of the longest side of the table = 2 × The width
Which gives;
Length of the longest side of the table = 2 × 1.25 m = 2.5 m
Length of other parallel side = 2.5 m - 1 m = 1.5 m
[tex]Area \ of \ a \ trapezoid = \mathbf{\dfrac{Sum \ of \ length \ of \ parallel \ sides}{2} \times Height}[/tex]
Which gives;
[tex]\mathbf{Area \ of}\ the \ \mathbf{table} = \dfrac{2.5 + 1.5}{2} \times 1.25 = 2.5[/tex]
The area of the = 2.5 m²

— length of the longest side of the table = 2 × width which gives you 'length of the longest side of the table = 2 × 1.25 meters' which equals 2.5 meters. to find length of other parallel side use the equation 2.5 meters minus 1 meter, which is 1.5 meters. lastly to find the area, do [tex]\frac{sum of length of parallel sides}{2}[/tex] multiplied by the height, which afer you fill it out turns into [tex]\frac{2.5+1.5}{2} *1.25[/tex] , which equals 2.5 meters. so the area is 2.5 meters squared.
