find the equation of the line with the coordinates of (-5,-2) and (5,3)
Answer
x - 2y = -1.
Step-by-step explanation:
Slope = (3 - (-2)) / (5 - (-5))
= 5/10
= 1/2
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
Here m = 1/2 and (x1, y1) = (5, 3):
y - 3 = 1/2(x - 5)
y - 3 = 1/2x - 5/2
y = 1/2x - 5/2 + 6/2
y = 1/2x + 1/2
Removing the fractions:
2y = x + 1
in standard form this is
x - 2y = -1

Jacob and Adam are selling pies for a school fundraiser. Customers can buy cherry pies and blackberry pies. Jacob sold 1 cherry pie and 1 blackberry pie for a total of $35. Adam sold 12 cherry pies and 9 blackberry pies for a total of $360. Find the cost each of one cherry pie and one blackberry pie. Write as an ordered pair. Ex: (cherry pie, blackberry pie)
Answer:
Step-by-step explanation:
c and b are the number of cherry and blackberry sold.
1c + 1b = 35
b = 35-c
12c + 9b = 360
12c + 9(35-c) = 360
3c = 45
c = 15
b = 35-c = 20
$15 for one cherry pie, $20 for one blackberry pie.
Probability of rolling a 2 or an odd number
Answer:
When rolling di.e #2, since we must roll a different odd number, the probability of doing so is 2/6 = 1/3. Thus, the probability is 1/2 x 1/3 = 1/6.
The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 246.8 and a standard deviation of 67.2. (All units are 1000 cells/μL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 179.6 and 314.0? b. What is the approximate percentage of women with platelet counts between 45.2 and 448.4?
Answer:
a. 68%
b. 99.7%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 246.8
Standard deviation = 67.2
a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 179.6 and 314.0?
By the Empirical Rule, approximately 68%.
b. What is the approximate percentage of women with platelet counts between 45.2 and 448.4?
45.2 = 246.8 - 3*67.2
448.4 = 246.8 + 3*67.2
Within 3 standard deviations of the mean, so approximately 99.7%.

Answer:
Mochi
Step-by-step explanation:
Mochi
Each week theres a increase of 4 in Mochi's weight. So you will add 4 twice to get to the 5th week.
4th week : 17
5th week : 21
Kappa
In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at.
on the 3rd week Kappa weighed 11
and 2nd week Kappa weighed 5
and 1st week Kappa weighed 3
Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier.
How to write and graph at least 10 on a number line
Answer:
hope it helps you (:
Step-by-step explanation:
Graphing an inequality on a number line, is very similar to graphing a number. For instance, look at the top number line x = 3. We just put a little dot where the '3' is, right?
Now an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it.
Just remember
if the symbol is (≥ or ≤) then you fill in the dot, like the top two examples in the graph below
if the symbol is (> or <) then you do not fill in the dot like the bottom two examples in the graph below
To better understand how to graph inequalities, look at the examples below or experiment with the grapher that is immediately below.

(-2,-19) and (-12,11) whats the slope
Answer: -3
Step-by-step explanation:
To find the slope, you can use the formula (y2-y1)/(x2-x1)
-----------------------------------------------------------------------------------------
Given
x1=-2
y1=-19
x2=-12
y2=11
Substitute values into the formula
(y2-y1)/(x2-x1)
=[(11)-(-19)]/[(-12)-(-2)]
=(11+19)/(-12+2)
=30/-10
=-3

Answer:
f(x) = -0.5x - 2;
At x = 0, f(x) = -2
At x = 1, f(x) = -2.5
At x = 2, f(x) = -3
At x = 3, f(x) = -3.5
At x = 4, f(x) = -4
g(x) = (2^(x - 1)) - 5;
At x = 0, g(x) = -4.5
At x = 1, g(x) = -4
At x = 2, g(x) = -3
At x = 3, g(x) = -1
At x = 4, g(x) = 3
Step-by-step explanation:
First equation;
f(x) = -0.5x - 2
f(0) = -0.5(0) - 2 = -2
f(1) = -0.5(1) - 2 = -2.5
f(2) = -0.5(2) - 2 = -3
f(3) = -0.5(3) - 2 = -3.5
f(4) = -0.5(4) - 2 = -4
For the second equation;
g(x) = (2^(x - 1)) - 5
g(0) = (2^(0 - 1)) - 5 = 2^(-1) - 5 = -4.5
g(1) = (2^(1 - 1)) - 5 = 2^(0) - 5 = -4
g(2) = (2^(2 - 1)) - 5 = 2 - 5 = -3
g(3) = (2^(3 - 1)) - 5 = 4 - 5 = -1
g(4) = (2^(4 - 1)) - 5 = 3
Given that f (x) = x help me plz
Answer:
Step-by-step explanation:
f(x) + g(x) = x^2 - 2x + x + 12
f(x) + g(x) = x^2 - x + 12
(f + g)( -1) = 1 + 1 + 12 = 14
f(x) - g(x) = x^2 - 2x - x - 12
f(x) - g(x) = x^2 - 3x - 12
(f + g)(-1) = (-1)^2 -(3)(-1) -12
(f + g)(-1) = 1 + 3 - 12
(f + g)(-1) = - 8
Laura received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.96 per pound. After buying the coffee, she had $56.13
left on her card. How many pounds of coffee did she buy?
Answer:
Step-by-step explanation:
Hi.
I can help.
First what we want to do is take what she had before spending any money and then take what she had after.
So :
$80.00
and
$56.13
Now to find how much she spent we can subtract these two numbers like so :
80.00 - 56.13
=
23.87
So now we know she spent a total of $23.87 on coffee in pounds.
Now if each pound of coffee costs $7.96 we can divide this into how much she spent $23.87 to find the total amount of pounds she bought for $7.96.
So:
23.87 / 7.96
=
About 3
She bought 3 pounds of coffee.

A truck is carrying passion fruit juice, cherry juice, and mango juice bottles in a ratio 1:2:7. If there are 34 cherry juice bottles, then how many nango juuce bottles are there?
Answer:
Step-by-step explanation:
We can solve this using a ratio. If there a 2 bottles of cherry in the ratio and there are 34 actual bottles of cherry, then the ratio is
[tex]\frac{ratio}{actual}:\frac{2}{34}[/tex]
In the ratio, we are told that the mix of bottles is 7 parts mango and we want to know how many actual bottles there are of mango. So filling in:
[tex]\frac{ratio}{actual} =\frac{2}{34} =\frac{7}{m}[/tex] and cross multiply to get
2m = 238 and
m = 119. There are 119 bottles of mango juice. And just for the record, there are 17 bottles of fruit juice.
Answer:
m = 119. There are 119 bottles of mango juice. there are 17 bottles of fruit juice.
Find the range of the function f(x) = 3x - 8
if the domain is {-4, 2, 7).
Answer:
f(-4)=3(-4)-8
f(-4)=-12-8
f(-4)=-20
f(2)=3(2)-8
f(2)=6-8
f(2)=-2
f(7)=3(7)-8
f(7)=21-8
f(7)=13
R=(-20, -2, 13)
The range of the function when f(x) = 3x - 8 and the domain is {-4, 2, 7) is (-20, -2, 13).
Calculation of the range:Since
f(-4)=3(-4)-8
f(-4)=-12-8
f(-4)=-20
Now
f(2)=3(2)-8
f(2)=6-8
f(2)=-2
Now
f(7)=3(7)-8
f(7)=21-8
f(7)=13
So,
R=(-20, -2, 13)
hence, The range of the function when f(x) = 3x - 8 and the domain is {-4, 2, 7) is (-20, -2, 13).
