We are trying to find the y-value when x = 2.
When x = 2, we see from the graph that our y-values is equal to -5.
Therefore, f(2) = -5

Evaluate:
-77 + (-46)
Answer:
-77 + (-46)
=> -77 - 46 (When you add two negative integers, it is the same thing as subtracting a positive integer with a negative integer)
=> -123 (Because a negative + a negative = a negative)
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
= -77 + ( - 46 )
= - 77 - 46 ( a positive integer and a negative integer makes a negative integer )
= -123 ( two negative signs resulted in the usage of addition )
Therefore , -77+ (-46) = -123
Question One
There are 7 linomen, 2 running backs, 1 fullback, and 1 quarterback on an American football team. What is the ratio, in simplest form,
of the number of linemen to the total number of players on the team?
A
1:2
B.
2:7
С
7:11
11:2
Question Two
Answer:
7:11
Step-by-step explanation:
No of linemen = 7
No of running backs = 2
No of fullback = 1
No of quarterback =1
The total no of players on the team = 7+2+1+1 = 11
We need to find the ratio of the number of linemen to the total number of players on the team.
R = 7/11
or
R = 7:11
Hence, the required ratio is 7:11.
- What is the area of the square?
(A) 16
(B) 25
(C) 32
(D) 36
(E) 41
Answer:
I counted 32 squares in and out
Answer:
A=a^2, so A=4^2=16 , or 4*4=16
Step-by-step explanation:
All sides of a square are equal, so the length of the sides are all 4. Put 4 in for a in the formula A=a^2 or Area = side length squared.
A = 4^2
A = 4 * 4
A = 16

Answer:
The mass in scientific notation is: [tex]5.45 * 10^{3}[/tex] .
(* means 'multiply')
Step-by-step explanation:
5450 kg in scientific notation is 5.45 times 10 to the 3rd power. If you multiply 10 to the 3rd power (1000) by 5.45, you get 5450 kg, which is the number we started out with.

What is the Slope of the line
Answer:
[tex]m=\frac{-3}{4}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-4-(-1)}{5-1}[/tex]
[tex]m=\frac{-4+1}{4}[/tex]
[tex]m=\frac{-3}{4}[/tex]
Set up a equation and solve for X.
Next to each step write the postulate or property used for that step
Answer:
[tex] x = 4 [/tex]
Step-by-step explanation:
[tex] GH = 3x [/tex] (given)
[tex] HJ = x + 16 [/tex] (given)
[tex] GJ = 32 [/tex] (given)
[tex] GH + HJ = GJ [/tex] (segment addition postulate)
[tex] (3x) + (x + 16) = 32 [/tex] (substitution)
Solve for x
[tex] 3x + x + 16 = 32 [/tex]
[tex] 4x + 16 = 32 [/tex]
[tex] 4x + 16 - 16 = 32 - 16 [/tex] (subtraction property of equality)
[tex] 4x = 16 [/tex]
[tex] \frac{4x}{4} = \frac{16}{4} [/tex] (division property of equality)
[tex] x = 4 [/tex]
