Step-by-step explanation:
What is the slope of a line perpendicular to the line whose equation is x-2y=12? Fully reduce your answer
Answer:
First, we need to solve the equation in the problem for y to put it in slope-intercept form so we can determine its slope:
2y−6x=4
2y−6x+6x=6x+4
2y−0=6x+4
2y=6x+4
2y2=6x+42
2y2=(6x2)+(42)
y=3x+2
The slope-intercept form of a linear equation is: y=mx+b
Where m is the slope and b is the y-intercept value.
Therefore the slope of this equation is m=3
A perpendicular line will have a slope (let's call this slope mp) that is the negative inverse of this line. Or, mp=−1m
Substituting gives:
mp=−13

The image shown is of two sets of parallel lines.
The m∠ 13 = 29x - 2 and the m∠ 9 = 27x + 6
What is the m∠ 12?
Answer:
x=4
m<12 = 66
Step-by-step explanation:
Answer:
x = 4
m∠12 = 66
m∠13 and m∠12 are linear pairs (supplementry angles)
Step-by-step explanation:
m∠9 ≈ m∠15 (Vertical angle)
m∠15 ≈ m∠13 (Corresponding angle)
m∠9 ≈ m∠13
29x - 2 = 27x + 6
2x - 2 = 6
2x = 8
x = 4
m∠13 = 29(4) - 2
m∠13 = 114
m∠13 + m∠12 = 180
180 - m∠13 = m∠12
180 - 114 = 66
m∠12 = 66

Step-by-step explanation:
Haley can read 5/8 pages in 2/3 minutes how many pages can she read in one minute
Given parameters:
Number of pages Haley can read = [tex]\frac{5}{8}[/tex] pages
Time to read the pages = [tex]\frac{2}{3}[/tex] min
Unknown:
Number of pages that can be read in 1 min = ?
Solution:
To solve this problem let us find Haley's rate;
Rate = [tex]\frac{Number of pages Haley can read}{Time }[/tex]
Input the parameters and find the rate;
Rate = [tex]\frac{5}{8} / \frac{2}{3}[/tex]
Rate = [tex]\frac{5}{8} x \frac{3}{2}[/tex]
Rate = [tex]\frac{15}{16}[/tex] pages/min
Now that we know the rate;
In 1 min; number of pages Haley can read;
Number of pages = Rate x time
Number of pages = [tex]\frac{15}{16}[/tex] x 1 = [tex]\frac{15}{16}[/tex][tex]\frac{15}{16}[/tex] pages
Haley can read pages [tex]\frac{15}{16}[/tex] in 1 minute.
Help 33-37 please will score as brainliest
Answer:
See below
Step-by-step explanation:
Quadratic function is in general form of:
y = ax^2 + bx + cThe function has a minimum if a > 0 and maximum if a < 0
The minimum or maximum point is a vertex of the graph
A vertex is the point x = -b/2aWhen b = 0, the min or max point equals to value of c.
33. It has maximum of -134. It has minimum of 735. It has minimum at x = - 8/4 = -2f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
36. It has maximum at x = -18/2(-3)= 3g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
37. It has minimum at x = - 6/(2*3/2) = - 2f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

Answer:
The length is 42 inches and the width is 14 inches
Step-by-step explanation:
You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.
You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.
Then you subtract 2y from both sides to get the unit value of y.
Y is equal to 18.
Then you can plug 18 into the y's to get
2(18)+6 which is 36+6 = 42
18-4 = 14
There you go.
The length is the longer side which is 42 inches and the width is 14 inches

I have 40 softballs i give 5 softballs to each player. How many players can i give softballs to so that i have at most 10 softballs left
Answer:
6
Step-by-step explanation:
5 to each players means you have 6 players and then you have 10 left for yourself
Answer:
You can hand out 5 softballs to 6 players.
Step-by-step explanation:
In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

Sebastian scored a 94% on a test. Frankie answered 43 questions correctly out of 50 total questions. Who scored higher on the test?
Answer:
Sebastian did.
Step-by-step explanation:
seb = 94% or 47/50
while frankie = 43/50 or 86%
Also look at 50 if you want and you can see it divides evenly with 100. Basically each mistake you make is 2 percent lost.
Answer: Sebastian
Step-by-step explanation: Divide 43 by 50.
43/50=0.86
tests are graded by the decimal point so he got 86%
since 94% is more than 86% sebastian scored higher

If g(x) = x2 – 4, then what is g(-4)?
0 -20
0 -8
O 12
O 20
Answer:
g(- 4) = 12
Step-by-step explanation:
To evaluate g(- 4), substitute x = - 4 into g(x), that is
g(- 4) = (- 4)² - 4 = 16 - 4 = 12
given that 5x - 8y = 29 find y when x = -1 give your answer as an improper fraction
Answer with step-by-step explanation:
If x = -1, we can re-write the equation as -5 - 8y = 29.
Step 1: Simplify both sides of the equation.
-5 - 8y = 29
-5 + (-8y) = 29
-8y - 5 = 29
Step 2: Add 5 to both sides.
-8y - 5 + 5 = 29 + 5
-8y = 34
Step 3: Divide both sides by -8.
-8y/-8 = 34/-8
y = -17/4

math question plz help
Answer:
1.8z^2
2.6p^5
3.Yes
Step-by-step explanation:
1.You have to use the Quotient Rule and subtract the exponents but sense they do not have the same base number you would divide the bases 24/3=8 and 4-2=2 and leave the variable the same
2.You would multiply 3*2 giving you six and then you would add the exponents together giving you 5 leaving 6p^5 as your final answer
3.When solving an equation like this you have to use The Product Rule meaning exponents with the same base number you would add the exponents which in this case results in 3+7=10 therefore leaving you with a^10

m - given number
2m - 2 times the number m
2m-3 - the difference of 2 times the number m and 3
the number 45 is no more than the difference of 2 times a number m and 3
45 ≤ 2m - 3
