Answer:
y = x + 1
Step-by-step explanation:
Equation of line : y = mx + b, m = slope, b = y intercept
Find slope, m
[tex]Slope, m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]= \frac{-3 - 4}{-4 - 3} \\\\=\frac{-7}{-7}\\\\=\frac{7}{7}\\\\= 1[/tex]
Equation of line : [tex](x_1, y_1) = ( 3, 4 )[/tex]
[ You can choose any set of points from the given points. ]
[tex](y - y_1) = m(x - x_1)[/tex]
[tex](y - 4 ) = 1 \times ( x - 3)\\\\y - 4 = x - 3\\\\y = x - 3 + 4 \\\\y = x + 1[/tex]

Answer:
Solution given:
5(x+2) = 11
dividing both side by 5
5(x+2)/5=11/5
x+2=11/5
subtracting both side by 2
x+2-2=11/5-2

Step-by-step explanation:
write an equation then find the angle measure for A. 25 points and brainliest.
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4 + 3x + 3x + 14 + 90 = 180 , simplify left side
108 + 6x = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
Then
∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A

Step-by-step explanation:
7x = x² - 8
=> x² - 7x - 8 = 0
use quadratic formula:
a = 1, b = -7, c = -8
x = [tex]\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}[/tex] (pls ignore the "A" I don't know why it's showing up)
=> x = [tex]\frac{-1±\sqrt{49 + 32} }{2}[/tex]
=> x = [tex]\frac{-1±9 }{2}[/tex]
=> x = [tex]\frac{-1 +9}{2}[/tex] = 4 or [tex]\frac{-1-9}{2}[/tex] = -5 (the answer is only 4 since it's asking for the positive solution)

If f(x) = x2 + 1 and g(x) = x – 4, which value is equivalent to (f circle g) (10)?
37
97
101
132
Answer:
A
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2+1\text{ and } g(x)=x-4[/tex]
And we want to find:
[tex](f\circ g)(10)[/tex]
This is equivalent to:
[tex]=f(g(10))[/tex]
Find g(10) first:
[tex]g(10)=(10)-4=6[/tex]
Substitute:
[tex]f(g(10))=f(6)[/tex]
Evaluate f(6):
[tex]f(6)=(6)^2+1=37[/tex]
Therefore:
[tex](f\circ g)(10)=37[/tex]
Our answer is A.

The function value at x = 2 would equal 8, but the limit as x approaches -0.5 would not approach the function value, but approach the hole in the function.

Find the measure of x and y ?
Answer:
x = 28
y = 47
Step-by-step explanation:
40 + 5x = 180 since it forms a straight line
5x = 180-40
5x = 140
Divide by 5
5x/5 = 140/5
x =28
3y-1 = 5x since they are alternate exterior angles
3y-1 = 140
Add 1
3y = 141
3y/3 = 141/3
y = 47

A town has a population of 5600 in 2014. If the towns population increases at an annual rate of 1.8%, determine the towns population in 2020. *
Answer:
In 2020 the population will be 6,233.
Step-by-step explanation:
Giving the following information:
Present value (PV)= 5,600
Growth rate (g)= 1.8%
Number of periods= 6 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 5,600*(1.018^6)
FV= 6,232.67 = 6,233
In 2020 the population will be 6,233.

Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris' age is 66. How old is Beatrice?
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9

What is the volume, in cubic feet, of the cement used to make the sidewalk? Show or explain all of the steps you used to determine your answer.
Part B
This diagram shows James’s design for the steps. The height of each step will be 6 inches. All angles in the diagram are right angles.
I need it now please!
The volume, of the cement used to make the sidewalk is 8 ft³
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
Given that, James is using cement to make a new sidewalk and new steps,
He will make a new rectangular sidewalk that is 8 feet long, 4 feet wide, and 0.25 foot thick.
Volume = length x width x height
Volume = 8 x 4 x 0.25 = 8 ft³
Hence, the volume, of the cement used to make the sidewalk is 8 ft³

The faces on a number cube are labled 1,2,2,3,4, and 5the number cube is rolled 114 times how many times would you expect the number 2 to apper
Given:
The faces on a number cube are labeled 1,2,2,3,4, and 5.
The number cube is rolled 114 times.
To find:
How many times would you expect the number 2 to appear?
Solution:
We have,
Total outcomes = 1,2,2,3,4, and 5.
Number of total outcomes = 6
Favorable outcomes = 2 and 2
Number of favorable outcomes = 2
The probability of getting 2 is:
[tex]P(2)=\dfrac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}[/tex]
[tex]P(2)=\dfrac{2}{6}[/tex]
[tex]P(2)=\dfrac{1}{3}[/tex]
Now, the expected number of times when 2 to appear is:
[tex]E(x)=114\times P(2)[/tex]
[tex]E(x)=114\times \dfrac{1}{3}[/tex]
[tex]E(x)=38[/tex]
Therefore, the expected number of times is 38.
The product of -12 and a number is 60
Answer:
-5
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
The result is positive, so you know the number must be negative. What two numbers normally make 60? That would be 5 and 12, but since the 12 is negative (-12), that means the 5 must be negative (-5). So, the answer is -5.
4. A rental car costs a one time fee of $180 and then an additional $65 for each day it is
rented. If the Neddles family's total bill was $520, how many days did they rent the car?
Answer:
5.23 =d
Step-by-step explanation:
cost = fee + daily charge*days
520 = 180+ 65d
Subtract 180
520 -180 = 180+65f-180
340 = 65d
Divide by 65
340/65 = 65d/65
5.23 =d
