Answer: Ok so the number on the y axis is 0,-3 cause it is above -4. And the next point is 1,-5. That is because the first thing you plot is the x axis and then the y axis so that it gives you your number
What is the slope (1,5),(10,2)
Answer:
m=-1/3
Step-by-step explanation
y2=2,y1=5 , x2=10 , x1= 1
m=y2-y1/x2-x1
m=2-5/10-1
m=-1/3

1. Miranda is braiding her hair. Then she will attach
beads to the braid. She wants of the beads to
be red. If the greatest number of beads that will
fit on the braid is 12, what other fractions could
represent the part of the beads that are red?
Complete question :
Miranda is braiding her hair then she will attach beads to the braids she wants 1/3 of the beads to be red if the greatest number of beads that will fit on the braid is 12 what other fraction could represent the part of the beads that are red?
Answer:
2 / 6
Step-by-step explanation:
Fraction of red beads on braid = 1/3
greatest number of braids = 12
Fraction of red beads = (1 /3) * 12 = 4 red beads
Thus implies that :
When greatest number of braids = 12
fraction of red beads) = (Number of red beads / greatest number of beads)
Fraction = 4 / 12
Divide by 2 = 2/6 (don't reduce to lowest term).
Match the statement with the inequality.
1. C
2. A
3.B
4.D
Step-by-step explanation:
A,B,C,D are the possible answers in order. 1,2,3,4 are the questions in order. 1. n is greater than or equal to 4 means that n's value is larger than 4 or 4. so it would be greater than with a line underneath. 2. n is less then 4. this means n's value is any real number less than 4. so it would be n is less than 4. n is less than or equal to 4 means that it can be any real number less than 4 or 4 itself, so it would be n is less than 4 with a line underneath. process of elimination leaves just 1 answer for 4
Sinead bought 2 shirts for 15.10 each and a pair of shoes for $42.42 If she paid for the items with a $100 bill, how much change
did she receive?
Answer:
27.38
Step-by-step explanation:
15.10 times 2 is 30.2
30.2+42.42=72.62
100-72.62=27.38

sina×tga=1/2, cosa=?
Answer:
cos a = -1.28 and 0.78
Step-by-step explanation:
The question is not properly written. This is the correct question:
If sina×tan(a) = 1/2, find cosa
According to trigonometry identity;
tan a = sina/cosa
sina×tan(a) = sin a * sina/cosa
sin²a/cos a = 1/2
(1-cos²a)/cosa = 1/2
Cross multiply
2(1-cos²a) = cos a
2 - 2 cos²a = cos a
2cos²a + cos a - 2 = 0
Let P = cos a
2P² + P -2 = 0
P = -1 ±√1-4(2(2)/2(2)
P = -1 ±√1+16/4
P = -1 ±√17/4
P = -1±4.12/4
P = -1-4.12/4 and -1+4.12/4
P = -5.12/4 and 3.12/4
P = -1.28 and 0.78
Since P = cos a
Hence cos a = -1.28 and 0.78
How to find percents of numbers using multiples of 100, 10, and 1%?
I need this for my summary, please help!!
Answer:
Im not too sure what the question is
Step-by-step explanation:
but when finding the percent of any number, 10% will always move the decimal over to the left once. So 10% of 300 is 30.0 This also works for 1%, you just move the decimal over twice. So 1% of 300 is 3

Is that the real answer at the top and what’s the Raleigh Rocket’s score ?
Answer:
The scores are as follows:
Caroline Castways = 72
Raleigh Rockets = 24
Step-by-step explanation:
Let c be the Castways score and r be the Raleigh Rocket’s score
Then
According to given statements, the equations will be:
[tex]c+r = 96\\r = \frac{1}{3}c[/tex]
From equation 2
[tex]3r=c[/tex]
Putting c = 3r in equation 1
[tex]3r+r = 96\\4r = 96\\\frac{4r}{4} = \frac{96}{4}\\r = 24[/tex]
Putting the value of r in equation 2
[tex]r = \frac{1}{3}c\\24 = \frac{1}{3}c \\c = 24*3\\c = 72[/tex]
Hence,
The scores are as follows:
Caroline Castways = 72
Raleigh Rockets = 24
The above problem has completed the first step, distributing both sides of the equation.
Finish the problem and determine the value of x.

Write the point-slope form of the equation of the line that passes through the points (-3,5) and (-1,4). Include your work
in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
Answer:
y - 4 = -1/2 (x+1)
Step-by-step explanation:
The point slope form of the equation is expressed as;
y-y0 = m(x-x0)
Get the slope
m = 4-5/-1-(-3)
m = -1/2
Substitute any of the point and m = -1/2 into the expression
y - 4 = -1/2 (x+1)
2(y-4) = -(x+1)
2y-8 = -x-1
2y+x = -1+8
2y+x = 7
Hence the required equation of the line is 2y+x = 7

Carlo sold his house for P8,000,000. The real-estate agent got a 5% commission from the sales.
From his commission, he has to pay BIR tax and other obligations required for the transfer of ownership
of the property to the buyer. This expense represents 6% of his total commission. How much net
amount will he receive?
Answer:
The net amount received is 7,120,000
Step-by-step explanation:
The computation of the net amount received is shown below:
= Sale value of the house - real agent commission - expenses
= 8,000,000 - 8,000,000 × 5% - 8,000,000 × 6%
= 8,000,000 - 400,000 - 480,000
= 8,000,000 - 880,000
= 7,120,000
Hence, the net amount received is 7,120,000
