-6-5-4-3-2-
Inequalities are used to represent unequal expressions
The solution to the system of inequalities is (-1,1)
How to determine the solutionThe system of inequalities is given as:
y > x + 2 and
y < 2x + 3
To do this, we start by plotting the graphs of the two inequalities
y > x + 2 and y < 2x + 3
See attachment for the graph
From the attached graph, both lines meet at (-1,1)
Hence, the solution to the system of inequalities is (-1,1)

Step-by-step explanation:
f(x)=x^2-x+3 what is f(4)
Answer:
15
Step-by-step explanation:
In the function f(x), x is the variable. So, whatever is in the parentheses, replacing x, should replace x throughout the entire function. So, to find f(4) simply plug in 4 for x.
First, rewrite the function with 4 as xf(4) = 4^2 - 4 + 3
Next, combine like termsf(4) = 4^2 - 1
Then, raise 4 to the power of 2f(4) = 16 - 1
Finally, subtractf(4) = 15
Answer:
f(4) = 15
Step-by-step explanation:
Substitute 4 for x and solve for f(4).
[tex]f(x)=x^2-x+3\\f(4)=(4)^2-4+3\\f(4)=16-4+3\\f(4)=15[/tex]

What is the solution to this system of linear equations?
x-3y=-2
x + 3y = 16
O (7, 3)
O (3,7)
O (-2, -3)
O (-3, -2)
Answer:
(7, 3)
Step-by-step explanation:
We can solve this system using elimination. In this scenario, we can eliminate x by subtracting the two equations:
x-3y=-2
x+3y=16
-3y-3y=-2-16
-6y=-18
Divide both sides by -6
y=3
Plug 3 back in for y to solve for x:
x-3(3)=-2
x-9=-2
Add 9 to both sides
x=7
(x, y) = (7, 3)

(5, 1) and (15, 16) are on the same line. What is the slope of the line? What is the y-intercept? Write the equation for the line.
Answer:
[tex]\displaystyle 3x - 2y = 13\:or\:y = 1\frac{1}{2}x - 6\frac{1}{2} \\ [0, -6\frac{1}{2}] \\ 1\frac{1}{2} = m[/tex]
Step-by-step explanation:
First, figure the rate of change [slope] out:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-1 + 16}{-5 + 15} = \frac{15}{10} = 1\frac{1}{2} \\ \boxed{1\frac{1}{2} = m}[/tex]
Now locate the initial value [y-intercept] by plugging an ordered pair into the slope-intercept formula. It does not matter which ordered pair you use:
_______________________________________________
[tex]\displaystyle y = mx + b[/tex]
16 = 1½[15] + b >> [tex]\displaystyle 16 = 22\frac{1}{2} + b; -6\frac{1}{2} = b[/tex]
OR
1 = 1½[5] + b >> [tex]\displaystyle 1 = 7\frac{1}{2} + b; -6\frac{1}{2} = b[/tex]
[tex]\displaystyle [0, -6\frac{1}{2}][/tex]
_______________________________________________
You now have your initial value. All that is left is to write the equation of this line, which can be written two ways:
> Slope-Intercept Form
[tex]\displaystyle y = 1\frac{1}{2}x - 6\frac{1}{2}[/tex]
> Standard Form [tex]\displaystyle [Ax + By = C][/tex]
y = 1½x - 6½
- 1½x - 1½x
___________
–1½x + y = –6½ [We CANNOT leave the equation this way, so multiply by –2 to eradicate the fraction\denominatour (if you wrote the equation as mixed numbers\if you wrote the equation as improper fractions).]
–2[–1½x + y = –6½]
[tex]\displaystyle 3x - 2y = 13[/tex]
With that, you have defined all the information.
[tex]\displaystyle -3x + 2y = -13[/tex]
*About this equation, INSTEAD of multiplying by –2, you multiply by its oppocite, 2. Now, you can leave it like this, but UNIVERSALLY, the A-term is positive, so you must multiply the negative out as well.

Take $27.99 from $42.79.
Answer:
14.8
Step-by-step explanation:
42.79-27.99=14.8
When subtracted $27.99 from $42.79, we get $14.8.
Subtraction is one of the most basic arithmetic operation in mathematics. Subtraction implies taking away one value from the another. Subtract x from y implies y - x. The number after from comes first. On subtraction, the sign (positive/negative) of the greater number of the two numbers given, is the sign (positive/negative) of the answer. Subtraction is also called as difference.

24. Human body temperatures have a mean of 98.2° and a
standard deviation of 0.62º. Sally's temperature has a z-score
of z= 2.1. What is her temperature? Show work.
Answer:
Step-by-step explanation:
We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.
To find Sally's temperature we will use z-score formula.
, where = Mean, = Standard deviation.
Let us substitute our given values in z-score formula.
Multiply 0.62 to both sides of equation.
Add 98.20 to both sides of equation.
Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.

what’s the answer to this geometry question??
Answer:
Step-by-step explanation:
The apothem of the square is four time lower than the area squared. Thus, to do this, we must use the formula A = s^2
Using this, we do A = s^2, and replace s for 12. Doing exponents first following order of operations (PEMDAS), we get 144. Now, that's only one side of the square. Since the square is 4 sides, we must multiply by four. Thus, your answer is (144 * 4) = 576 cm^2.
Answer: 576 cm squared.
• Jami and Mami together had $32. Jami
said, "If you give me $5, we'll have the
same amount." How much did each
one have?
Answer:
Jami has $13.5
Mami has $18.5
Step-by-step explanation:
Let j = Jami's money
m - Mami's money
j + m = 32
j = m - 5 (Since Jami basically has 5 less than Mami)
Substitute the j in the top equation
m - 5 + m = 32
2m - 5 = 32
Add 5 to both sides
2m - 5 = 32
2m = 37
Divide both sides by 2
2m/2 = 37/2
m = 37/2 = 18.5
Now plug the new m into the bottom equation
j = 18.5 - 5
j = 13.5

Two brothers, Charles and Brian,each inherit $30000. Charles invests his inheritance ina a savings account with an annual return of 2.5 %, while Brian invest his inheritance ina CD paying 6.2% annually. How much more money than Charles does Brian have after 1 year?
Answer:
$1,110
Step-by-step explanation:
You have to use the interest formula to calculate how much each brother will have after a year.
A = P(1+r)^t
A = future/ending value
P = principle
R = interest rate
T = time (given in years)
Charles = 30,000(1+.025)^1 = 30,750
Brian = 30,000(1+.062)^1 =31,860
31,860-30,750=1,110
Brian will have $1,110 more than Charles after 1 year
