Answer:
24x² - 46x + 7
Step-by-step explanation:
Area of the shaded region = area of the larger square - area of the smaller square
✔️Area of the larger square = s²
= (5x - 4)²
= (5x - 4)(5x - 4)
= 5x(5x - 4) -4(5x - 4)
= 25x² - 20x - 20x + 16
= 25x² - 40x + 16
✔️Area of smaller square = s²
= (x + 3)² = (x + 3)(x + 3)
= x(x + 3) +3(x + 3)
= x² + 3x + 3x + 9
= x² + 6x + 9
✔️Area of the shaded region = (25x² - 40x + 16) - (x² + 6x + 9)
= 25x² - 40x + 16 - x² - 6x - 9 (distributive property)

X + 4 < 6 help.......
Answers
Answer:
x<2
Step-by-step explanation:
Hello There!
Our objective for this problem is to isolate the variables
To do so we use inverse operations
x+4<6
subtract 4 from each side
4-4 cancels out
6-4=2
we're left with
x<2
Step-by-step explanation:
It is just like a normal x equation just with an inequality. So for now, just represent the < as and =
so we have x+4=6
subtract 4 from both sides
x+4-4=6-4
x=2
Now we insert the <
x<6
so all values for x are all less than 6
Hope that helps :)

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle
So basically
∠XYZ=∠WXY+∠XWY
so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)
115-45=70 so ∠XWY=70
Answer:
?+45=115° sum of two interior angle of the triangle is equal to the exterior angle
<XWY=115-45=70

Step-by-step explanation:
1). System of equations is,
-2x - y = -22 -------(1)
4x - 8y = 4 -------(2)
By satisfying these equations with the given point (9, 4),
Equation (1)
-2(9) - 4 = -22
-18 - 4 = -22
-22 = -22
True.
Equation (2)
4(9) - 8(4) = 4
36 - 32 = 4
4 = 4
True.
Given point lies on both the equations.
Therefore, the given point is the solution of the system of equations.
2). 3x - 3y = 27 -----(1)
-2x + 9y = -11 ------(2)
Satisfy the equations with the given point (-10, -1)
Equation (1)
3(-10) - 3(-1) = 27
-30 + 3 = 27
-27 = 27
False.
Equation (2)
-2x + 9y = -11
-2(-10) + 9(-1) = -11
20 - 9 = -11
11 = -11
False.
Therefore, the given point is not the solution of the system of equations given.
Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56. Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60. What system of equations can be used to find the price of a package of sugar cookies and a package of oatmeal cookies? (sugar cookies: x and oatmeal cookies: y )
Answers
Answer:
The system that can be used is:
[tex]10x + 2y = 56[/tex]
[tex]9x + 3y = 60[/tex]
Step-by-step explanation:
We have that:
x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.
Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.
This means that:
[tex]10x + 2y = 56[/tex]
Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.
This means that [tex]9x + 3y = 60[/tex]
System that can be used:
The system that can be used is:
[tex]10x + 2y = 56[/tex]
[tex]9x + 3y = 60[/tex]
Complete the square to re-write the quadratic function in vertex form:
y = x2 – 7x - 6
Answers
Answer:
y = (x - 3.5)^2 - 18.25
Step-by-step explanation:
y = x^2 – 7x - 6
y = (x^2 – 7x) - 6
y = (x^2 – 7x + 3.5^2 - 3.5^2) - 6
y = (x^2 – (2)(3.5)x + 3.5^2) - 3.5^2 - 6
y = (x - 3.5)^2 - 3.5^2 - 6
y = (x - 3.5)^2 - 18.25

(Round your answer to two decimal places.) s =
Answers
Answer:
a) x = 1.52
b) s = 1.16
Step-by-step explanation:
We have that:
5 students watched 0 movies.
9 students watched 1 movie.
5 students watched 2 movies.
5 students watched 3 movies.
1 student watched 4 movies.
(a) Find the sample mean x.
Sum divided by the number of students. So
[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]
(b) Find the approximate sample standard deviation, s.
Standard deviation of the sample.
Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So
[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]

Answers
Answer:
the principal balance at the beginning of June is $22,222.22
Step-by-step explanation:
The computation of the principal balance at the beginning of June is shown below:
Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)
= $250 ÷ (13.5% ÷ 12)
= $22,222.22
Hence, the principal balance at the beginning of June is $22,222.22

graphed. What is the solution to the system of equations?
A. (0,-7)
B. No solution
C. (0,0)
B. Infinitely many solutions
Answers
Answer:
Step-by-step explanation:
Note that the two equations are equivalent.
2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.
Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.
