What is the slope of a line parallel to the line represented by the equation -9x + 3y = 1 ?
Answer:
Slope of a parallel line: 3
Step-by-step explanation:
-9x + 3y = 1
3y = 9x + 1
y = 9/3x + 1/3
Slope= 9/3 = 3
The canine tooth of a Bengal tiger is 4 inches long. There are 2.54 centimeters in one inch. How long is the tooth in centimeters? Write an expression to show the length of a Bengal tiger's canine tooth in centimeters.
Answer:
The Bengal tiger's canine tooth is 10.16 cm long.
Step-by-step explanation:
1 inch = 2.54 cm so 4 inches = ?cm
1/2.54 = 4/? set up a proportional ratio : inch/cm = inch/cm and solve
? = 2.54(4)
? = 10.16cm. long

In the FreeWheelin' Skate Shop, exactly 1/4 of the skateboards are red and exactly 2/3 of the scooters are red. If there are equal numbers of red skateboards and red scooters in the shop, what fraction of the total skateboards and scooters together are red? Express your answer as a simplified fraction.
============================================================
Explanation:
Let's say we had 12 skateboards and 12 scooters. I'm picking 12 because 4*3 = 12 after multiplying the denominators. Doing this trick will mean we end up with whole number results instead of decimals.
If we had 12 skateboards, then (1/4)*12 = 3 of them are red. Having 12 scooters means (2/3)*12 = 8 scooters are red.
Add up the counts of each red item to get 3+8 = 11 red items out of 12+12 = 24 items total. Therefore, the answer is 11/24
Side note: The fraction 11/24 cannot be reduced because 11 and 24 have no factors in common other than 1.
What's 15/11 and a mixed number?
15/11 is a mixed number already, it is 1.363636363636........
Answer:
[tex]1\frac{4}{11}[/tex]
Step-by-step explanation:
You can read [tex]\frac{15}{11}[/tex] as "15 divided by 11"
So to figure out the mixed number, you do just that.
11 goes into 15 1 time, then you subtract 11 from 15, which gives you a remainder of 4. You put 4 as your numerator and 11 is your denominator.
I've attached an image that shows the math. Hope that helps!

simplify (x - y)^2 - 2(x - y) + 1
Answer:
(x-y-1)^2 or [(x-y)-1]^2
Step-by-step explanation:
We are given the expression:-
[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 }[/tex]
Let A = (x-y)^2
[tex] \displaystyle \large{ A^{2} - 2 A+ 1 }[/tex]
From:-
[tex] \displaystyle \large{ {x}^{2} - 2x + 1 = {(x - 1)}^{2} }[/tex]
Thus:-
[tex] \displaystyle \large{ {A}^{2} - 2A + 1 = {( A- 1)}^{2} }[/tex]
Rewrite A in (x-y)^2.
[tex] \displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 = {( (x - y) - 1)}^{2} }[/tex]

angle 3 is a complement of angle 4, and m angle 3 = 46°
find m angle 4°
The measure of ∠4 = 44°.
We have two angles ∠3 and ∠4 which are complementary of each other.
We have to find the measure of ∠4.
What are Complementary angles?Two angles are said to be complementary if their sum is equal to 90°.
Mathematically - x + y = 90°
According to the question -
∠3 = 46°
∠4 = x (Let)
Now, ∠3 and ∠4 are Complementary angles. Therefore -
∠3 + ∠4 = 90°
∠4 = 90 - ∠3
∠4 = 44°
Therefore -
∠4 = 44°
Hence, the measure of ∠4 = 44°.

Find the equation of the line. Use exact numbers.
Answer: y = 5/5x - 5
Step-by-step explanation:
Find the equation of the line that
is perpendicular to y = –
-x and
contains the point (4,-8).
y=
x + [ ]
Answer:
y = 3x/2-14
Step-by-step explanation:
We are given that the line is perpendicular to y = -2/3 and contains (4,-8).
Perpendicular Def.
[tex] \displaystyle \large{m_1m_2 = - 1}[/tex]
Both slopes multiply each others equal to -1.
Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.
[tex] \displaystyle \large{ - \frac{2}{3} m_2 = - 1}[/tex]
Multiply both sides by 3.
[tex] \displaystyle \large{ - \frac{2}{3} m_2( 3) = - 1(3)} \\ \displaystyle \large{ - 2 m_2= - 3} \\ \displaystyle \large{ m_2= \frac{3}{2} }[/tex]
Therefore, another slope that is perpendicular to -2/3 is 3/2.
Then rewrite in slope-intercept form.
Slope-Intercept
[tex] \displaystyle \large{y = mx + b}[/tex]
where m = slope and b = y-intercept; substitute m = 3/2 in.
[tex] \displaystyle \large{y = \frac{3}{2} x + b}[/tex]
Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.
[tex] \displaystyle \large{ - 8 = \frac{3}{2} (4) + b} \\ \displaystyle \large{ - 8 = 3(2)+ b} \\ \displaystyle \large{ - 8 = 6 + b} \\ \displaystyle \large{ - 8 - 6 = b} \\ \displaystyle \large{ - 14 = b}[/tex]
Therefore, b is -14; rewrite again in slope-intercept form.
Thus:-
[tex] \displaystyle \large{y = \frac{3}{2} x + b} \\ \displaystyle \large{y = \frac{3}{2} x - 14}[/tex]

Find the measure of the missing angle.
Answer:
34
Step-by-step explanation:
if you add 90+56 you get 146 and then 180-146=34
Answer:
a = 34°
Step-by-step explanation:
1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.
2. This means that a + 90 + 56 = 180.
3. (Solving equation above).
Step 1: Simplify both sides of the equation.
[tex](a)+(90+56)=180[/tex] [tex]a + 146 = 180[/tex]Step 2: Subtract 146 from both sides.
[tex]a+146 - 146 = 180 - 146[/tex] [tex]a = 34[/tex]Step 3: Check if solution is correct.
[tex](34) + 90 + 56 = 180[/tex] [tex]124 + 56 = 180[/tex] [tex]180 = 180[/tex]Therefore, a = 34°.

If triangle PQR is plotted, it will have the following coordinates, P(-4, 0), Q(4, 2) and R(-2, 4
If point R is translated 4 units right and 7 units down, what are the coordinates of R’? Explain your answer
[ it is a coordinate graph with a 12 y axis and a 8 x axis I couldn’t put in a picture it’s too big ]
============================================================
Explanation:
Point R is located at (-2,4)
Shift it to the right 4 units to move it to (2,4). Note how I added 4 to the x coordinate.
Then we subtract 7 from the y coordinate to move it 7 units down. We move from (2,4) to (2,-3) which is where point R' is located.
Check out the diagram below.
