Answer:
A. 15x^3 -44x^2 +9x +28
Step-by-step explanation:
(5x^2 -3x -4)(3x - 7)
first, distribute by multiplying the terms in each parenthesis with each other:
(5x^2 * 3x) - (3x * 3x) - (4 * 3x) - (5x^2 * 7) + (3x * 7) + (4 * 7)
simplify:
15x^3 -35x^2 -9x^2 +21x -12x +28
Now combine like terms:
15x^3 -44x^2 +9x +28

Find an equation for the line with the given properties. Express the equation in slope-intercept form.
Slope = 3; containing the point (5,-4)
What is the equation of the line?
y =
Answer:
y = 3x - 19
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define variables
Slope m = 3
Random point (5, -4)
Step 2: Plug in known variables
y = 3x + b
Step 3: Find b
-4 = 3(5) + b
-4 = 15 + b
b = -19
Step 4: Write linear equation
y = 3x - 19
Can someone give me the answer
Answer:
You earned 260$ before they taxed
Calculate the average speed between 120 s and 160 s
Average Speed = Total Distance / Total Time
Given:Total Distance = 150 m
Total Time = 160 - 120 = 40 s
To Find:Average Speed
Solution:Average Speed = 150/40
Average Speed = 3.75 m/s
Answer:3.75 m/s
reasoning can you name a real number that is represented by √-36? Explain
Your question has been heard loud and clear
√-36 is by no means a real number. This is because square roots can only be positive in nature.
Eg: -2*-2 = 4 and 2*2 = 4 , so √4 = -2 or 2 but √-4 doesnt exist.
So , √-36 also does not exist while √36 exists.
√-36 , we can however represent it as an imaginary number as 36i

7. Identify the explicit formula for the sequence given by the recursive formula
Answer: B) f(n) = 30 - 8(n - 1)
Step-by-step explanation:
Explicit formula is of the form: [tex]a_n=a_1+d(n-1)[/tex] where
[tex]a_1[/tex] is the first term d is the difference between consecutive termsGiven: f(1) = 30 --> this represents the first term [tex]a_1[/tex] = 30
f(n - 1) - 8 --> this means the previous term minus 8 thus d = -8
[tex]a_n[/tex] = 30 + (-8)(n - 1)
= 30 - 8(n - 1)
Answer:
B. f(n) = 30 – 8(n – 1)

A gardener fills a 2 1/2 cubic foot wheelbarrow 2/3 of the way without soil weight 75.25 pounds. What is the weight of the soil un wheelbarrow?
Volume of wheelbarrow , V = 2 1/2 ft³ = 5/2 ft³.
Volume of soil in wheelbarrow , [tex]v = \dfrac{5}{3}\ ft^3[/tex] .
Mass of soil in wheelbarrow , m = 75.25 pounds.
Now, volume left , [tex]v'=\dfrac{5}{6}\ ft^3[/tex] .
Let, mass of soil un wheelbarrow is x.
[tex]x=\dfrac{\dfrac{5}{6}\times 75.25}{\dfrac{5}{3}}\\\\x=37.625\ pounds[/tex]
Hence, this is the required solution.

For an indirect proof, what must first be assumed to prove that LaTeX: \angle X∠ Xis a right angle?
Answer:
If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.
Step-by-step explanation:
An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.
< X = right angle = [tex]90^{o}[/tex]
A right angle is one that is equal to [tex]90^{o}[/tex]. As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.

Which statement about the graph is true? 7 6 5 2 3 2 1 1 2 3 4 5 6 7 8 x O The graph shows a proportional relationship because it is a line, and the difference between each point is the same. The graph shows a proportional relationship because it is a line, and each x-value isha multiple of 2. O The graph does not show a proportional relationship because each point written as a ratio gives a different value.
Answer:
I think but it can also be the first one
The graph shows a proportional relationship because it is a line, and each x-value isha multiple of 2.

Step-by-step explanation:
Gertrude is correct. Any angle can have one line of symmetry going directly down the center of the angle, intercepting at the angles point. Emmet is incorrect because not only polygons can have lines of symmetry. A circle, square, rhombus, etc. can have lines of symmetry.

a(2a - 3) + 6(a - 0.5) - (2a^2 - 5)
Answer:
The answer to your question is 3a+2
Answer:
3a +2
Step-by-step explanation:
a(2a -3) +6(a -0.5) -(2a^2 -5)
rewrite to all show terms and operations:
a * (2a -3) + 6 * (a - 0.5) -1 * (2a^2 -5)
distribute:
2a^2 -3a +6a -3 -2a^2 +5
combine like terms:
-3a +6a -3 +5

Determine whether the given segments have the same length. Drag and drop each number
into the correct box to complete the justification of your answer. BC and EF
Answer:
Step-by-step explanation:
Length of a segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Coordinates of extreme ends of BC and EF are,
B(1, 4), C(3, -2), E(-3, -2) and F(-1, 1)
Length of BC = [tex]\sqrt{(1-3)^2+(4+2)^2}[/tex]
= [tex]\sqrt{4+36}[/tex]
= [tex]2\sqrt{10}[/tex] ≈ 6.32 units
Length of EF = [tex]\sqrt{(-3+1)^2+(-2-1)^2}[/tex]
= [tex]\sqrt{4+9}[/tex]
= [tex]\sqrt{13}[/tex] ≈ 3.61 units
The length of BC is 6.32. The length of EF is 3.61.So, BC and EF don't have the same length.
how many fourths are in one third?
Answer:
there is one fourth in one third
Step-by-step explanation:
1/3 < 1/2
one third is less than two fourths (one half)
1/3 > 1/4
but it is more than one fourth, so one fourth fits in one third.

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select ALL of the true statements.
Segment EF is twice as long as segment AB.
True/false
B. Segment CD is twice as long as segment FG.
True/false
C. The measure of angle HEF is twice the measure of angle DAB.
True/false
D. The length of segment EH is 16 units.
True/false
E. The measure of angle BCD is the same as the measure of angle GFE.
True/false
Answer: True, False, False, True, False
Step-by-step explanation:
Since the two quadrilaterals are similar, for question A your answer of True is correct since EF would scale to be twice as long as AB. For the second question the reverse logic applies. For Question C EH is 16 units since 8x2 is 16. For the last question, since BCD does not corresponds to GFE, it is false. Angle BCD has a vertex at point C and GFE has a vertex at point F. Since C does not correspond to F, the angles are not the same.

The quotient of a number and 17 is 118.82.
A. it can be solved with division property of equality.
B. It can be solved with the multiplication property of equality
C. The equation should x/17=118.82
D.x=7
E. X=2020
Answer:
C. The equation should x/17=118.82
Step-by-step explanation:
We know that
Dividend ÷ Divisor = Quotient
Dividend/Divisor = Quotient
From the question, we are told that:
The quotient of a number and 17 is 118.82
Let us represent the unknown number as x = Dividend
17 = Divisor
Quotient = 118.82
Hence,
x / 17 = 118.82
Cross Multiply
x = 17 × 118.82
x = 2019.94
The correct answer = Option C. The equation should x/17=118.82
