Answer:
if the solutsion are r1,r2 then the factored form is
y=a(x-r1)(x-r2) where a is a constant
so
r1=-1/3
r2=4
y=a(x-(-1/3))(x-4)
y=a(x+1/3)(x-4)
so it will be
y=a(x+1/3)(x-4)
a is a constant

Answer:
The answer is A. 6.4 and 5.6 and D. 39 and 27.
Step-by-step explanation:
A. 6.4 and 5.6 = 1.6 and 1.4
6.4 / 1.6 = 4
1.4 * 4 = 5.6
So A is correct.
D. 39 and 27 = 13 and 9
39 / 13 = 3
9 * 3 = 27
So D is correct.
Hope this helps! :)

Determine whether the triangles are congruent. Explain your reasoning .
SAS (Side, Angle, Side) or ASA (Angle, Side, Angle)
Answer:
Yes, SAS Theorem
Step-by-step explanation:
The triangles are congruent because of SAS Theorem that states that if two triangles have two sides and the angel in between them congruent the triangles are congruent.
JK≅NM (Side) because the sides have the same measure 74in. they are ≅
∡J≅∡M (Angle) because the angles have same measure 37° they are ≅
JL≅PM (Side) because the sides have the same measures 46in. they are ≅
Which correlation coefficient would indicate a strong negative correlation? a. r = -0.93 b. r = -0.23 c. r = 0.75 d. r = 1.0
Answer:
A. r = -0.93
Step-by-step explanation:
First, if there is a negative correlation, the correlation coefficient will be negative.
This eliminates answer choices C and D, which are positive.
If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).
Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.
So, the correct answer is A. r = -0.93
4 1/2 ounces per 3/4 miles
_____ ounces per 1 mile
Answer: 6
Step-by-step explanation:
To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.
[tex]\frac{3}{4}[/tex]×[tex]\frac{4}{3} =1[/tex]
We need to multiply the 4 1/2 ounces by 4/3 too
[tex]4\frac{1}{2}[/tex]×[tex]\frac{4}{3} =6[/tex]
4 1/2 ounces per 3/4 miles
6 ounces per 1 mile
Answer:
6 ouncesStep-by-step explanation:
Let the unknown number be x
[tex]4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile[/tex]
Now simply use cross multiplication to solve it
[tex]4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4} \\ [/tex]
Now make x as the Subject
[tex] \frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x[/tex]
So the answer is
6 ouncespls anyone that can help

Solve the formula d = rt for r.
Robert is selling his bulldozer at a heavy equipment auction. The auction company receives a commission of 5% of the selling price. If Robert owes $124,850 on the bulldozer, then what must the bulldozer sell for in order for him to be able to pay it off?
Answer:
$131422
Step-by-step explanation:
Given :
Amount owed = $124,850
Commison on sale = 5%
Let :
Sale price of bulldozer = x
Sale price = amount owed + 5% of sale price
x = 124850 + 0.05*x
x = 124850 + 0.05x
x - 0.05x = 124850
0.95x = 124850
x = 124850 / 0.95
x = 131421.05263
To the nearest dollar = $131422
Do the side lengths 7, 20 and 21 form a right triangle?
==============================================
Work Shown:
a^2+b^2 = c^2
7^2+20^2 = 21^2
49+400 = 441
449 = 441
We end up with a false equation, so the original equation is false for those a,b,c values.
By the pythagorean theorem converse, we do not have a right triangle.
Because a^2+b^2 > c^2, this triangle is acute.

Answer:
5x -7y = -3
Step-by-step explanation:
The equation of the perpendicular line can be written using the given equation as a starting point. Swap the x- and y-coefficients and negate one of them. In standard form, the x-coefficient must be positive.
Find the new constant by using the x- and y-values of the given point.
-7x -5y = 9 . . . . given equation
-5x -7y = c . . . . equation with coefficients swapped
5x -7y = c . . . . . equation with swapped coefficients, x-coefficient negated
5x -7y = c = 5(-2) -7(-1) = -10 +7 = -3
The equation of the perpendicular line is ...
5x -7y = -3

Given that the area of the trapezoid is 55cm find x
Answer: The value of x is 13.
Step-by-step explanation:
Area of trapezoid = [tex]\dfrac{1}{2}\times\text{sum of parallel sides}\times\text{height}[/tex]
Here , Parallel sides = 9 cm , x cm
Height (Altitude ) = 5 cm
Area = 55 sq. cm
Substitute all values in the formula , we get
[tex]55=\dfrac12\times{(9+x)}\times5\\\\ \dfrac{2\times55}{5}=9+x\\\\ 22=9+x\\\\ x=22-9\\\\ x=13[/tex]
Hence, the value of x is 13.

2.A ball is pulled out of a bag on the first pick. Then, it
is replaced in the bag and another ball is picked out . Independent or dependent ?
Answer:
Independent
Step-by-step explanation:
Since the ball is replaces, the same number of balls and type of balls are in the bag. The draw is identical to the first draw so the draws are independent.
Here's an equation of a line:
y - 4x = 4
Which of the following is the equation of a line
that is parallel?
Click on the correct answer.
4y + x= -8
y + 4x = 1
2y – 8x = -5
- 4y + x= -8
Step by step explaination
y-4x= -4
y= 4x-4
