PLEASE HELP!!!Which statement is true? Select all that apply.
The relationship is proportional.
The slope is -6.
The slope is negative.
The y-intercept is -3.
The equation of the line is y = -3x
Answer:
"The relationship is proportional."
"The relationship is proportional."
"The equation of the line is y = -3x"
Step-by-step explanation:
First, a proportional relationship can be written as:
y = k*x
where k is called the constant of proportionality. (or the slope)
You can see that if we take x = 0, we have
y = k*0 = 0
Then this type of line always passes through the point (0, 0).
And in the graph you can see that this line does that, then:
"The relationship is proportional." is true.
We also can see that as x increases, the value of y decreases, this must imply that k is a negative number, then:
"The slope is negative." is true.
To find the value of the slope, we can take two points that belong to the line.
I will choose:
(0, 0) and (2, -6)
For the slope, we just take the quotient between:
Δy = -6 - 0 = -6 (the difference in the y-components)
Δx = 2 - 0 = 2 (the difference in the x-components)
the slope is:
k = Δy/Δx = -6/2 = -3
Then the slope is -3, and we can write the equation as:
y = -3*x
Then:
"The equation of the line is y = -3x" is true.

Ms. Larson was driving home from a vacation. At noon, she was 120 miles from home. Half an hour later, she was 98 miles from home. If Ms. Larson traveled at a constant rate during this time, what was her speed?
Answer: her speed was “44 miles per hour”
Assuming Ms. Larson was travelling at a constant speed in that half hour, her speed would have been 44 miles per hour.
In order to find the speed of something, use the formula:
= Distance / Time
The distance was:
= First distance from home - Second distance from home
= 120 - 98
= 22 miles
The time was half an hour so will be presented as:
= 0.5 hours
The speed is therefore:
= 22 / 0.5
= 44 miles per hour
In conclusion, Ms. Larson is going at 44 miles per hour.

What are the roots of the polynomial equation x cubed minus 5 x + 5 = 2 x squared minus 5? Use a graphing calculator and a system of equations. Round noninteger roots to the nearest hundredth.
–3, –5
–2.24, –2, 2.24
–2.24, 2, 2.24
3, 5
Answer:
c
Step-by-step explanation:
–2.24, 2, 2.24
The solution to the equation of the polynomial function [tex]x^3 - 5x + 5 = 2x^2 - 5[/tex] is (c) –2.24, 2, 2.24
How to determine the roots of the polynomial?The function is given as:
[tex]x^3 - 5x + 5 = 2x^2 - 5[/tex]
Split the function.
So, we have:
[tex]y = x^3 - 5x + 5[/tex]
[tex]y = 2x^2 - 5[/tex]
Using a graphing calculator, we have the x coordinate at the point o intersection of both equations to be
x = –2.24, 2, 2.24
Hence, the solution to the equation is (c) –2.24, 2, 2.24

Determine the area of the shaded region (grey) in the quadratic form.
Hint: Shaded area = (gray rectangle area) – (white rectangle area)
Answer:
The area of shaded region is: [tex]13x^2+6x-15[/tex]
Step-by-step explanation:
We can see in the diagram that
[tex]Length\ of\ gray\ rectangle = l_g = 3x+5\\Width\ of\ gray\ rectangle = w_g = 4x-3[/tex]
The area of rectangle is given by:
Area = Length * width
Now for gray rectangle
[tex]A_g = l_g * w_g\\= (3x+5)(4x-3)\\= 3x(4x-3)+5(4x-3)\\= 12x^2-9x+20x-15\\=12x^2+11x-15[/tex]
For White Rectangle:
[tex]Length = l = 5-x\\Width = w = x\\A_w = l * w\\A_w = (5-x)(x)\\= 5x-x^2[/tex]
Now,
The area of shaded region will be calculated by subtracting the area of white triangle from the gray triangle.
[tex]A_s = A_g - A_w\\= (12x^2+11x-15) - (5x-x^2)\\=12x^2+11x-15-5x+x^2\\=12x^2+x^2+11x-5x-15\\=13x^2+6x-15[/tex]
Hence,
The area of shaded region is: [tex]13x^2+6x-15[/tex]
Need help with this slide about proofs explanation would be nice aswell.
Answer:
1. AB ~= DF
2. Definition of Congruent
3. Reflexive Property of Congruency
4 BD=BD
6. AB+BD=AD; DF+BD=BF
7. Substitution Property of Equality
8. Definition of Congruent
Step-by-step explanation:
1. The given always goes first, and that's the first reason, so AB ~= DF must be the first statement (that should be the congruency symbol).
2. The definition of congruent is that if they are congruent then they are equal. Since that statement made two congruent lines equal, it must be the definition.
3. The reflexive property means something is congruent to itself, and BDis BD, therefore it is the reflexive property.
4. Remember if something is congruent then it is equal.
6. The segment addition postulate states that if we are given two points on a line segment, then AB+AC=AC.
7. In this statement AD was substituted for DF+BD. This can be done because of AB=DF and BD=BD as aforementioned.
8. If two things are congruent then they are equal by definition of congruency.

Select all that apply. What are some uses for the distance formula? Finding the perimeter of polygons. Finding the area of rectangles. Finding the equation of a circle. Finding the midpoint of segments. Finding how much gas you will need on a trip.
Answer:
Everything except the finding the midpoint
Step-by-step explanation:
If the question states the points of a shape, you can find the perimeter and the area of the polygon because you would know the dimensions and the lengths of each side, but in the options, it says the area of a rectangle, and it doesn't have to be a rectangle
You can find the equation of the circle, by finding the diameter of the circle and the radius. With the diameter, you would be able to find the centre of the circle and then you need to divide the diameter by two to get the radius.
For the midpoint, you use the midpoint formula. You just need to sub in the points into the formula and you would get the midpoint
When you are given two points on a graph (or worded problem), and it says that for every x number of km it uses y amount of gas and the question asks to find how much gas is needed in between these two points, you can do this. Find the distance between the two points and then use algebra to work out the amount of gas required

Find the discriminate
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
Answer:729
Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729
