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
Hope this helps!! :)

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

Fractions and ratios cannot have zero in the denominator.
Fractions and ratios can be simplified the same way.
Fractions and ratios are different names for the same thing.
Some fractions and ratios can be written as mixed numbers.
Answer:
b and c
Step-by-step explanation:
The statements that are true are:
Fractions and ratios cannot have zero in the denominator.
Fractions and ratios can be simplified in the same way.
Fractions and ratios are different names for the same thing.
Options A, B, and C are correct.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Fraction is written as:
1/2, 3/4, 5/6
Where 1, 3, and 5 are numerators and 2, 4, and 6 are denominators.
The ratio is written in the form a:b.
1:2 = 1/2
4:8 = 4/8 = 1/2
Fractions and ratios cannot have zero in the denominator.
This is true because if we have zero in the denominator the fraction becomes undefined.
Example:
1/0 = ∞
The ratio can not have zero in the denominator because we are comparing two units where neither one unit can be zero.
Fractions and ratios can be simplified in the same way.
This is true.
Example:
Fraction = 2/4 = 1/2
Ratio = 2:4 = 2/4 = 1/2
Fractions and ratios are different names for the same thing.
This is true.
Because ratio can be written as a fraction.
Example: 2:3 = 2/3
Some fractions and ratios can be written as mixed numbers.
This is not true
Fractions can be written as a mixed numbers.
Example:
5/2 = [tex]2\frac{1}{2}[/tex]
Ratios can never be written as a mixed number.
Thus,
The statements that are true are:
Fractions and ratios cannot have zero in the denominator.
Fractions and ratios can be simplified in the same way.
Fractions and ratios are different names for the same thing.
Options A, B, and C are correct.

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

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.
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.
Hope this helps,

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.

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%.

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.

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
