Use the slope-intercept form to graph the equation
Question content area bottom left
Part 1
Use the graphing tool to graph the line. Use the slope and y-intercept when drawing the line.
The graph of the equation y = -6/7x + 2 that shows the slope and y-intercept is shown in the image attached.
What is the Slope-Intercept Form of the Equation of a Line?y = mx + b represents the equation of a line in slope-intercept form. In y mx + b, we have the following parameters of the line it represents:
m = the slope of the line, which is the change in y / the change in x or rise/run of the line.b = the point the line intercepts at the y-axis which is the y-intercept where x = 0.Given the equation of a line in slope-intercept form as y = -6/7x + 2, it means that the graph of the line you are to plot would have a negative slope (m) of -6/7, and must intercept the y-axis at y = 2.
So, to draw the line of the equation that was given in slope-intercept form as y = -6/7x + 2, you have to use a slope of -6/7 that show the steepness of the line, and a y-intercept of 2, that shows where the line intercepts the y-axis of the graph at y = 2, of which the corresponding x-coordinate must be equal to zero.
Therefore, the graph of y = -6/7x + 2 is shown below.

The measure of the triangle for the value of x is x = 11.
What is defined as the triangle?A triangle is a 2-dimensional closed shape with three sides, three angles, and three vertices. A triangle is a type of polygon.
The sum of a triangle's three interior angles is always 180°.The sum of any two triangle sides is always larger than the length of a third side.A triangle's area is equal to half the product of the its base and height.For the given value of triangle;
The three angles are given as;
3x + 84x + 1184By the sum of all angles of triangle property.
The sum of all three angles of the triangle is 180°
Thus,
3x + 8 + 4x + 11 + 84 = 180
Simplifying;
7x = 180 - 103
7x = 77
x = 11
Thus, the solution of x of the given triangle is found as x = 11.

Answer:
6 out of 24
Step-by-step explanation:
5+5+6+8 = 24

f(x)=x^2+9 and g(x)=x^2-9
The composite result function of ( f ° g )(x) in the given functions f( x ) = x² + 9 and g( x ) = x² - 9 is x⁴ - 18x² + 90.
What is the composite result function of ( f ° g)(x) in the given function?A function is simply a relationship that maps one input to one output.
Given the data in the question;
f( x ) = x² + 9g( x ) = x² - 9( f ° g)(x) = ?First, we set up the composite result function f(g(x)).
f( x ) = x² + 9
f( g(x) ) = f( x² - 9 ) = ( x² - 9 )² + 9
f( g(x) ) = ( x² - 9 )² + 9
Expand the parenthesis
f( g(x) ) = ( x² - 9 )( x² - 9 ) + 9
f( g(x) ) = ( x²( x² - 9 ) -9( x² - 9 ) + 9
f( g(x) ) = x⁴ - 9x² - 9x² + 81 + 9
Collect and add like terms
f( g(x) ) = x⁴ - 18x² + 81 + 9
f( g(x) ) = x⁴ - 18x² + 90
Therefore, ( f ° g )(x) in the given functions is x⁴ - 18x² + 90.

If a triangle has an area of 20in every dimension of the triangle is multiplied by a scale factor, and the new triangle has an area of 180in . the scale factor is 3.
Scale factorFirst step is to calculate the area
Area:
Area = New triangle /Old triangle
Area = 180 / 20
Area = 9
Second step is to calculate the ratio of areas
Ratio of areas :
Ratio of areas = 9
Ratio of areas = (3)²

Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
Answer:
(-5, -3)
Step-by-step explanation:
We can use the fact that the diagonals of a parallelogram bisect each other
Let me classify the points as
A (-4, 7)
B (2, -5)
C (3, 5)
Let us assume the 4th vertex is D(x, y) where x and y have to be determined
We will assume that AB is the diagonal of the parallelogram ABCD
The midpoint of a line segment from (x1, y1) to (x2, y2) is given by
(1/2)(x1 + x2, y1 + y2) ie the average of their x and coordinates
If we let O be the midpoint of AB, coordinates of O are
1/2 x (-4 + 2, 7 -5) = 1/2 x ( -2, 2) = (-1, 1)
We know the other diagonal CD must pass through point O and O is also the midpoint of CD
Therefore if coordinates of D are (x, y)
then x-coordinate of O which is -1 should be the average of x coordinate of C and x coordinate of D
==> - 1 = (3 + x)/2
=> -2 = 3 + x
=> -2 - 3 = x
=> -5 = x
=> x = -5
Similarly
1 = (5 + y)/2
=> 2 = 5 + y
=> 2 - 5 = y
=> -3 = y
y = -3
So the coordinate of the fourth vertex D are (-3, -5)

Ariana owns a food truck that sells tacos and burritos. She only has enough supplies
to make 120 tacos or burritos. She sells each taco for $3.75 and each burrito for
$7.25. Ariana must sell no less than $580 worth of tacos and burritos each day. If x
represents the number of tacos sold and y represents the number of burritos sold,
write and solve a system of inequalities graphically and determine one possible
solution.
One possible solution to the system of inequalities is (90, 50)
How to solve the system of inequalities graphically?From the question, we have the following parameters:
Supplies = 120 tacos or burritos
This means that
x + y = 120
Where x represents the number of tacos and y represents the number of burritos
Also, we have
She must sell no less than $580
This means that
3.75x + 7.25y >= 580
So, we have the system of inequalities to be given as
x + y = 120
3.75x + 7.25y >= 580
Next, we plot the system of inequalities on a graph
See attachment for the system of inequalities on a graph
From the attached graph, we have both lines of the graph intersect at (82.857, 37.143)
When the point is moved to the shaded region, we have one of the possible points to be (90, 50)
Hence, the solution to the system of inequalities is (90, 50)

They intersect at point (6,3).
Considering the definition of parallel line, the statement "They are parallel" describes the graph of y= -x+3 and y=-x+6.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where:
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Parallel lineParallel lines are two lines that are always at the same distance from each other and that prolonged towards infinity never touch.
Two lines are parallel if they have the same slope or value of m and different y-intercepts or value of b.

Missing value of the table is 9.
Define equivalent ratios.When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent. If two or more ratios have the same value when reduced to their most basic form, they are said to be equal. For instance, the ratios 1:2, 2:4, and 4:8 are identical. When reduced to their most basic form, all three ratios have the same value, or 1:2. We can multiply or divide the words by a natural number to get analogous ratios to a given ratio. When two words are co-prime (have just one other common factor), we multiply them by any natural number instead of performing the division procedure.

Step-by-step explanation:
So we know that the perimeter of a rectangle =2(Length*Breadth)
Given =
Area of the rectangle = 35 [tex]in.^{2}[/tex]
Length = 7 in.
Area of a rectangle = Length*Breadth
35 = 7*Breadth
[tex]\frac{35}{7}[/tex] = Breadth
5 = Breadth
Now we can find out the perimeter of the rectangle =
= 2(Length*Breadth)
= 2(7*5)
= 2*35
= 70 in.
