Answer:
C (37, 77)
Step-by-step explanation:
Option A:[tex]291=2(145)+3\\\\291=290+3\\\\\boxed{291\neq 293}[/tex]
Option A is not a solution.
Option B:[tex]163=2(78)+3\\\\163=156+3\\\\\boxed{163\neq 159}[/tex]
Option B is not a solution.
Option C:[tex]77=2(37)+3\\\\77=74+3\\\\\boxed{77=77}[/tex]
Option C is a solution.
Hope this helps.
Answer:
C
Step-by-step explanation:
To determine which point is a solution, substitute the x- coordinate into the equation and if the value is equal to the y- coordinate then it is a solution
A (145, 291 )
y = 2(145) + 3 = 290 + 3 = 293 ≠ 291 ← not a solution
B (78, 163 )
y = 2(78) + 3 = 156 + 3 = 159 ≠ 163 ← not a solution
C (37, 77 )
y = 2(37) + 3 = 74 + 3 = 77 ← solution to the equation

What is the absolute value of -7? 7 - 1/7 1/7
Answer:
7
Step-by-step explanation:
First ones 7 second ones 7 third ones 1/7 forth ones 1/7
Step-by-step explanation:
Because absolute value basically means the distance from zero so the distance from zero from -7 is 7 the same with 7 and the distance from zero with -1/7 is you guested it 1/7 and follow suit for 1/7 and you got your answers
Hope this helps ;)

the domain of y=log(9-x^2),xER, is
Step-by-step explanation:
log(z) is defined when z > 0.
For log(9 - x²) to be defined, we have 9 - x² > 0.
=> x² < 9, -3 < x < 3.
The domain of y = log(9 - x²) is (-3,3).

Answer: C) All real values of x such that [tex]x \le 0[/tex]
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,
[tex]-2x \ge 0 \\\\-2x+2x \ge 0+2x \ \text{ ... add 2x to both sides}\\\\0 \ge 2x\\\\2x \le 0 \ \text{ ... flip both sides, and the inequality sign}\\\\x \le 0/2 \ \text{ ... divide both sides by 2}\\\\x \le 0[/tex]
As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.

The following chart shows the number of rows in an auditorium and the total number of seats. What equation defines the number of seats with respect to the number of rows.
a) S=20R+100
b) S=40R+120
c) S=20R+60
d)S=20R
Answer:
Answer: c) S=20R+60
Step-by-step explanation:
Linear Model
The chart supplied shows the number of rows (R) in an auditorium and the total of seats (S).
We'll find the equation that relates them. The equation of a line can be expressed in the slope-intercept form:
S = mR + b
Where m is the slope and b is the intercept.
The slope is found by:
[tex]\displaystyle m=\frac{S_2-S_1}{R_2-R_1}[/tex]
We'll use two sample points (20,460) and (45,960):
[tex]\displaystyle m=\frac{960-460}{45-20}=\frac{500}{25}[/tex]
m = 20
The value of b can be found by using one of the points, for example (20,460), and having m=20:
460 = 20*20 + b
Thus: b = 460 - 400 = 60.
The equation is:
S = 20R + 60
You can test the other points and check they belong to the same line.
Answer: c) S=20R+60
What is 6 to the power of 7 divided by 6 to the power of 5, in index form?
What’s the answer ?? The triangle says 84 degrees
Answer:
x = 48°
Step-by-step explanation:
x + x + 84° = 180°
2x = 180° - 84°
2x = 96°
x = 96°/2
x = 48°
Answer:
84+2a=180
2a=180-84
= 96
2a=96/2
=48
So, each angles are 48 degrees.

Ms. Sanchez bought 3 pounds of turkey to make sandwiches for her family. She uses 1/3 of a pound for each sandwich. How many sandwiches can she make?
Answer:
the total number of sandwich required is 9
Step-by-step explanation:
The computation of the number of sandwiches made is as follows:
She bought 3 pounds
And one third of pound she required for each sandwhich
So, the total number of sandwich required is
= 3 ÷ 1 ÷ 3
= 3 × 3
= 9
Hence, the total number of sandwich required is 9
The same is to be considered
How many triangles can I make out of this shape?
Answer:I think it is 84
Step-by-step explanation: 9.3 x 9
Answer:
1,302 triangles
Step-by-step explanation:
All triangles are formed by the intersection of three diagonals at three different points. There are five arrangements of three diagonals to consider. We classify them based on the number of distinct diagonal endpoints. We will directly count the number of triangles with 3, 4, and 5 endpoints. We will then count the number of potential triangles with 6 endpoints, then correct for the false triangles.
You can make 84 triangles with 3 diagonal endpoints, 504 triangles with 4 diagonal endpoints, 630 triangles with 5 diagonal endpoints, and 84 triangles with 6 diagonal endpoints. This adds up to be 1,302 triangles altogether.

6 x - 2 (x - 5) = 22
Answer:
x = 2.75
Step-by-step explanation:
6x - 2 (x - 5) = 22
6x -2x + 10 = 22
4x + 10 = 22
- 10 - 10
4x = 11
11/4 = 2.75
x = 2.75

Answer:
20
Step-by-step explanation:
12/3 (the number of croutons) = 4
Since 4 is your base number, you would multiply 4 x 5.
20 olives
Answer:
20
Step-by-step explanation:
Ratio of olives : croutons is 5 : 3.
If you put 12 croutons, you put 4 times the amount of croutons in the ratio since 12/3 = 4.
That means you must also put 4 times the number of olives.
4 * 5 = 20

Answer:
Yes
Step-by-step explanation:
Yes
Answer:
No, the answer is suppose to be 9.
Step-by-step explanation:
if you did 54 divided by 18 you would get 3. so if you do 54 divided by 3 you would get 18. then if you do 27 divided by 3 it would equal 9.
so therefore your answer will be 9.

write in standard form (×+4)(×-5)=4 find the value of a,b,c
Answer:
[tex]x^{2}[/tex] - x - 24 = 0
a = 1
b = 1
c = -24
Step-by-step explanation:
(x + 4)(x - 5) = 4
x(x - 5) = [tex]x^{2}[/tex] - 5x
4(x - 5) = 4x - 20
[tex]x^{2}[/tex] - 5x + 4x - 20 = 4
[tex]x^{2}[/tex] - x - 20 = 4
[tex]x^{2}[/tex] - x - 20 - 4 = 0
[tex]x^{2}[/tex] - x - 24 = 0
a = 1
b = 1
c = -24
