Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 2 ← is in slope- intercept form
Thus its graph is a straight line
crosses the y- axis at (0, 2 ) , that is c = 2
the 4 in 4x is the slope m of the line
The endpoints of AC are A(-8, 9) and C (1, -3). Point B(-2, 1) lies on AC. What
is the ratio AB: BC?
A 1:2
B
1:1
C) 2:1
D) 3:1
Answer:
c)2:1..................
Answer:
C
Step-by-step explanation:
Find the distance of AB:
Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]
[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]
Find the distance of BC:
Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]
[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]
AB=10 units
BC=5 units
AB:BC = 10:5=2:1

i need the domain and range
Answer:
domain: -1<x range:y<-1
Step-by-step explanation:
seeing as how the x value seems to start at -1, but keeps going past that to the right, we can get the equation x>-1. seeing as how the y value seems to start at -1, but keeps going down, we can get the equation y<-1.

Answer:
p(- 3) = - 79
Step-by-step explanation:
Substitute x = - 3 into p(x) , that is
p(- 3) = 4(- 3)³ + 2(- 3)² - 3(- 3) + 2
= 4(- 27) + 2(9) + 9 + 2
= - 108 + 18 + 11
= - 108 + 29
= - 79

Write the sum of 7divided by 7x^6+ 4 dividend by 7x^6 in simplest form, if x = 0
Answer:
0
Step-by-step explanation:
The equation if I read this correctly is:
(7 / 7x⁶+4) / 7x⁶
Using x = 0 you would have:
[7 / (7(0)⁶+4)] / 7(0)⁶
(7 / 0 +4) / 0
(7/4) / 0 which is the same as 7/4 x 0 = 0

A worker has job offers from two companies. The information below summarizes the job offer from each company.Company A:Starting salary of $31,000Raise of $3000 each yearCompany B:Starting salary of $38,000Raise of $2000 each yearPart A: Write an equation in terms of n years that can be used to determine the number of years when the salaries would be the same for both companies.Part B: Use the equation you wrote in part A to determine the number of years it would take for the salaries to be the same for both companies. Use mathematics to support your answer.
Using linear functions, we have that:
A.
For Company A: [tex]S_A(n) = 31000 + 3000n[/tex]
For Company B: [tex]S_B(n) = 38000 + 2000n[/tex]
B. The salaries will be the same after 7 years.
A linear function is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.Item a:
For Company A, the salary starts at $31,000, with a raise of $3,000 each year. Thus, [tex]b = 31000, m = 3000[/tex], and the salary after n years is given by:[tex]S_A(n) = 31000 + 3000n[/tex]
For Company B, the salary starts at $38,000, with a raise of $2,000 each year. Thus, [tex]b = 38000, m = 2000[/tex], and the salary after n years is given by:[tex]S_B(n) = 38000 + 2000n[/tex]
Item b:
They will be the same after n years, for which:[tex]S_A(n) = S_B(n)[/tex]
Then
[tex]31000 + 3000n = 38000 + 2000n[/tex]
[tex]1000n = 7000[/tex]
[tex]n = \frac{7000}{1000}[/tex]
[tex]n = 7[/tex]
The salaries will be the same after 7 years.

If three dice are rolled, what chance is there
of throwing a total of 3?
Answer:
Just as one die has six outcomes and two dice have 62 = 36 outcomes, the probability experiment of rolling three dice has 63 = 216 outcomes. This idea generalizes further for more dice. If we roll n dice then there are 6n outcomes.
We can also consider the possible sums from rolling several dice. The smallest possible sum occurs when all of the dice are the smallest, or one each. This gives a sum of three when we are rolling three dice. The greatest number on a die is six, which means that the greatest possible sum occurs when all three dice are sixes. The sum of this situation is 18.
When n dice are rolled, the least possible sum is n and the greatest possible sum is 6n.
There is one possible way three dice can total 3
3 ways for 4
6 for 5
10 for 6
15 for 7

3x+10=43 what is x to the what are the steps to equal X to the math equation
Answer:
x = 11
Step-by-step explanation:
When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:
3x = 33
Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!
