-114
Answer:
114
Step-by-step explanation:
To evaluate f(7) substitute x = 7 into f(x), that is
f(7) = 268 - 22(7) = 268 - 154 = 114

Answer:
exact form: 2 ^3√2
Step-by-step explanation:
An environment group invited 450 people to a fundraising event .315 people accepted the invention. What percent of the people accepted the invitation
Given:
Total number of invited people = 450
Total number of people who accept the invitation = 315
To find:
The percent of the people who accepted the invitation.
Solution:
We need to find 315 is what percent of 450.
[tex]\%=\dfrac{\text{Number of invited people - Who accept the invitation}}{\text{Number of invited people}}\times 100[/tex]
[tex]\%=\dfrac{450-315}{450}\times 100[/tex]
[tex]\%=\dfrac{135}{45}\times 10[/tex]
[tex]\%=3\times 10[/tex]
[tex]\%=30[/tex]
Therefore, 30% of the people accepted the invitation.

Answer:
y= -6/5x -3
Step-by-step explanation:
So for now lets bring it into mx + b format
Subtract 6x from both sides to isolate y which is also called subtraction property of equality.
so 5y = -6x -15
Now you divide both sides by 5 which is called division property of equality.
You now have y = -6/5x - 3
y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.
Hope this helps!
7/8 = 21/k whats k
Answer:
k = 24
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define
7/8 = 21/k
Step 2: Solve for k
Cross-multiply: 7k = 168Divide both sides by 7: k = 24Step 3: Check
Plug in k to verify it's a solution.
Substitute: 7/8 = 21/24Simplify: 7/8 = 7/8Here we see that 7/8 does indeed equal 7/8. ∴ k = 24 is a solution.

what is an expression equivalent to
4b + 5y - 3b + 8y
Answer:
b + 13y
Step-by-step explanation:
4b + 5y - 3b + 8y = 4b - 3b + 5y + 8y
I rearranged the like terms together.
4b - 3b + 5y + 8y = b + 13y
Simplify.

quadrilateral ABCD is inscribed in circle E. the m<A=152 find m<C
Answer:
The angle for C is 28°.
Step-by-step explanation:
In a cyclic quadrilateral, opposite angles are supplementary which means that both angles add up will be 180° :
∠A + ∠C = 180°
152° + ∠C = 180°
∠C = 180° - 152°
∠C = 28°
Answer:
B. 28

Step-by-step explanation:
The point (2, 1) is a solution to which of the following systems of equations?
2x + y = 5 and −2x + y = 2
−2x − y = −5 and 2x − y = 2
−x + y = 3 and −3x + y = −5
x + y = 3 and 3x − y = 5
[tex]\huge\boxed{\left \{ {{x+y=3} \atop {3x-y=5}} \right.}[/tex]
We can solve this problem by testing the solution against each system of equations. We'll do this by substituting the point into each equation for each system.
System 1 - [tex]\Large\textbf{X}[/tex][tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}2x+y&=5\\2(2)+1&=5\\4+1&=5\\5&=5\\&\checkmark\end{aligned}&\begin{aligned}-2x+y&=2\\-2(2)+1&=2\\-4+1&=2\\-3&=2\\&\text{X}\end{aligned}\end{array}[/tex]
System 2 - [tex]\Large\textbf{X}[/tex][tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-2x-y&=-5\\-2(2)-1&=-5\\-4-1&=-5\\-5&=-5\\&\checkmark\end{aligned}&\begin{aligned}2x-y&=2\\2(2)-1&=2\\4-1&=2\\3&=2\\&\text{X}\end{aligned}\end{array}[/tex]
System 3 - [tex]\Large\textbf{X}[/tex][tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-x+y&=3\\-2+1&=3\\-1&=3\\&\text{X}\end{aligned}&\begin{aligned}-3x+y&=-5\\-3(2)+1&=-5\\-6+1&=-5\\-5&=-5\\&\checkmark\end{aligned}\end{array}[/tex]
System 4 - [tex]\Large\checkmark[/tex][tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}x+y&=3\\2+1&=3\\3&=3\\&\checkmark\end{aligned}&\begin{aligned}3x-y&=5\\3(2)-1&=5\\6-1&=5\\5&=5\\&\checkmark\end{aligned}\end{array}[/tex]
Since both equations in the final system are true when solved with [tex](2, 1)[/tex], the answer is the last system.

Step-by-step explanation:
Alex is making chocolate cakes. For each cup of milk he uses, he needs to use 1/2 cups of flour. For each
cup of flour he uses, he needs to use 1/3 cup of cocoa powder. Alex is making enough cakes that he needs
to use 4 cups of milk. How many cups of cocoa powder does Alex need to use?
answer: 2/3 (or 0.67) cups of cocoa
Step-by-step explanation: since you need to use 1/2 cups of flour for each cup of milk you divide 4 by 2 and you get 2 then you multiply 2 by 1/3 to get your answer

Consider the equation and its solution.
8(x-2) = 64
8x-18-84
8x = 80
X=10
Which property is used in the last step to find thatx-10?
distributive property
addition property of equality
subtraction property of equality
division property of equality
Answer:
division property of equality
Step-by-step explanation:
The property used in the last step to find x = 10 in the expression is the division property of equality.
8(x-2) = 64
8x-18 = 84
8x = 80
x = 10
In 8x = 80 ;
Division property of equality was used to find the value of x.
The property states that when we divide both sides by a non-zero value, the two sides remains the same.
