Which expression has a positive quotient?
Negative three-fourths divided by Negative two-thirds
Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth
2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth
Negative 6 divided by Five-thirds
Answer:
Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.
Step-by-step explanation:
We will solve to find out Which expression has a positive quotient.
We know the division rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex] and [tex]\frac{-a}{b}=\frac{-a}{b}[/tex]
We will use these rules
1) Negative three-fourths divided by Negative two-thirds
[tex]=\frac{-\frac{3}{4} }{-\frac{2}{3} }\\=-\frac{3}{4}\times -\frac{3}{2}\\=\frac{9}{8}[/tex]
The quotient is positive.
2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth
[tex]\frac{-\frac{1}{8} }{3\frac{1}{5} }\\=\frac{-\frac{1}{8} }{\frac{16}{5} }\\=-\frac{1}{18} \times \frac{5}{16}\\=-\frac{5}{288}[/tex]
The quotient is negative.
3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth
[tex]\frac{2\frac{2}{7} }{-\frac{1}{5} }\\= \frac{\frac{16}{7} }{-\frac{1}{5} }\\=\frac{16}{7} \times -5\\=-\frac{80}{7}[/tex]
The quotient is negative.
4) Negative 6 divided by Five-thirds
[tex]\frac{-6}{\frac{5}{3} }\\=-6 \times \frac{3}{5}\\=-\frac{18}{5}[/tex]
The quotient is negative.
So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.
Option A is correct.

Q1: What signals you that factoring by grouping is the best method to use when factoring a
problem? How would you know if it is factorable or prime?
Answer:
You know a number is not factorable or prime if nothing multiplies to it.
Step-by-step explanation:
For example there are no numbers that multiple to 7, same with 19. No 2 numbers will ever be able to = to 7 or 19 for example.
Hope this helps!!!
Answer:
prime numbers would be 2,4,6,8,10,12, and etc.....
Step-by-step explanation:
factorable means say we have the number 32 it factors down to 16 then 16 factors down into 8 then 8 goes down into 4 then 4 goes dow into 2
hope this helps

Determine the number of lines of symmetry for the figure.
Answer:
theres 26 lines of symmetry i think....hope this helps:)
Help asap please!! I will mark you as brainliest :)
Answer:
12Step-by-step explanation:
The answer is 12 because is you subtract 2 by 12 then you get 10.
Here's why that's correct.
[tex]\frac{5}{2}[/tex] [tex]or[/tex] [tex]2.5[/tex] is equal to [tex]\frac{10}{4}[/tex] which is also [tex]2.5[/tex]
This is correct because if you multiply both the numerator and the denominator by 2, you get [tex]\frac{10}{4}[/tex] because if you multiply 5 times 2, that equals 10. Then if you multiply 2 times 2, you get 4, which eventually makes 10 over 4, or [tex]\frac{10}{4}[/tex].

13. Describe the number of solutions for the equation. (1 point)
3(x – 3) = 3x
O one solution
O no solution
O infinite solutions
What one
Answer:
no solution
Step-by-step explanation:
Given
3(x - 3) = 3x , that is
3x - 9 = 3x ( add 9 to both sides )
3x = 3x + 9 ( subtract 3x from both sides )
0 = 9 ← not possible
This indicates the equation has no solution

Two people decided to race. One of the cars is 10 meters north of the start line 5 seconds into the race. After 15 seconds, the car is 25 meters north of the start line. Calculate the average velocity of the car.
Answer:
The average velocity of the car is 1.5 m/s
Step-by-step explanation:
The given parameters are;
The displacement of one of the cars north of the start after 5 seconds = 10 meters
The displacement of the car north of the start after 15 seconds = 25 meters
The average velocity of the cars [tex]\overline v[/tex] is given as follows;
[tex]\overline v = \dfrac{\Delta x}{\Delta t}[/tex]
Where;
Δx = The change in the displacement of the car = 25 m - 10 m = 15 m
Δt = The corresponding amount of the change in time 15 s - 5 s = 10 s
By substituting the known values of Δx and Δt in the equation for the average velocity of the car, [tex]\overline v[/tex], we have;
[tex]\overline v = \dfrac{15 \ m}{10 \ s} = 1.5 \ m/s[/tex]
∴ The average velocity of the car, [tex]\overline v[/tex] = 1.5 m/s
Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points)
y = x2 - 20
Shift the graph of y = x2 left 20 units.
Shift the graph of y = x2 up 20 units.
Shift the graph of y = x2 down 20 units.
Shift the graph of y = x2 right 20 units.
Answer:
Equation : y = x2 - 20
Intercepts
when y is zero (0), x is 10
when x is zero (0), y is -20
Therefore, shift the graph, y=2x down to the negative y-axis 20 units
ALTERNATIVELY: Shift the graph to the right of positive x-axis 10 units.

Which values are in the solution set of the compound inequality -8 <3x +7s 10? Select three options.
O-15
O-5
O-3
O1
Step-by-step explanation:
-8 < 3x + 7 <= 10
-15 < 3x <= 3 (subtract 7)
-5 < x <= 1 (divide by 3)
Hence the correct options are -3, 0 and 1.
When I multiply two variables, what operation do I use for the exponents to combine them?
Answer:
Multiplying exponents with the same base
When you multiply two variables or numbers that have the same base, you simply add the exponents.

3 =2 = 90
4= 1 = 38
for explanation check your own previous question
its the same thing
Answer:
see explanation
Step-by-step explanation:
• The diagonals bisect each other at right angles, then
∠ 2 = ∠ 3 = 90°
∠ 1 = 180° - (90 + 52)° ← angle sum of a triangle
∠ 1 = 180° - 142° = 38°
• Diagonals bisect the endpoints, then
angle at vertex with ∠ 1 = 76° and
angle at vertex with ∠ 4 = 76°, thus
∠ 1 = ∠ 4 = 38°
In conclusion
∠ 1 = 38°, ∠ 2 = 90°, ∠ 3 = 90°, ∠ 4 = 38°

A.
The graph flips over the y-axis.
B.
The graph flips over the line y = x.
C.
The graph flips over the x-axis.
Answer: C) The graph flips over the x axis.
This is because we're multiplying the y outputs by -1, to make them flip in sign from positive to negative (or vice versa).
Let's say the point (1,2) is on the f(x) curve. Multiplying y = f(x) by -1 will make the point turn into (1,-2). Apply this logic to every point on the f(x) curve and we end up with f(x) reflected over the horizontal x axis.
The notation we could write is either g(x) = -1*f(x) or g(x) = -f(x).

What is m∠SRW?

Answer:
m∠SRW = [tex]126^{o}[/tex]
Step-by-step explanation:
Given: <VRW = 3x
<TRS = (2x + 18)
What is m∠SRW?
<TRS = <VRW (vertically opposite angles)
2x + 18 = 3x
18 = 3x - 2x
x = 18
<VRW = 3x = 3 x 18 = [tex]54^{o}[/tex]
<TRS = (2x + 18) = 92 x 18 + 18)
= [tex]54^{o}[/tex]
Also,
<TRV = <SRW (vertically opposite angles)
So that,
<TRU + <URV = <SRW
But,
<TRV + <SRW + <TRS + <VRW = [tex]360^{o}[/tex]
<TRV + <SRW + [tex]54^{o}[/tex] + [tex]54^{o}[/tex] = [tex]360^{o}[/tex]
<TRV + <SRW + [tex]108^{o}[/tex] = [tex]360^{o}[/tex]
<TRV + <SRW = [tex]360^{o}[/tex] - [tex]108^{o}[/tex]
<TRV + <SRW = [tex]252^{o}[/tex]
2 <SRW = [tex]252^{o}[/tex] (∵ <TRV = <SRW)
<SRW = [tex]\frac{252}{2}[/tex]
= [tex]126^{o}[/tex]
Therefore,
m<SRW = [tex]126^{o}[/tex]

Given that cosA = -8/17 and sinA is negative, determine the value of tanA.
Answer:
tan A = -15/8.
Step-by-step explanation:
sin^2a = 1 - cos^2A
= 1 - (-8/17)^2
= 225/289
So sin A= 15/17
tan A = sin A / cos A
= 15/17 / -8/17
= 15/-8
= -15/8.
