Answer:
1) m = -1
2) m = -8/3
Step-by-step explanation:
The slope is the number in front of x. If there is no number then it is one. If x is positive it will be a positive one and if x is negative it will be a negative one.
Use the slope-intercept form to find the slope.

Answer:
6
Step-by-step explanation:
I used a calculator because I don't think you need to show work on this problem if you do tell me, and I'll edit my answer.
Once you plug in your numbers in the distance formula you get 6
Since it is only asking for the distance you don't need to worry about the midpoint.
A painter mixes cans of green and white paint to make the shade needed for painting a bedroom. The table shows the
ratios he can use for the color he wants.
Green cans (g) 6 10 16 18
White cans (W) 915 24 27
Which is a direct variation equation for this relationship?
Answer:
A. 2/3w
Step-by-step explanation:
Option A is correct, g = 2/3 w is a direct variation equation for the given relationship
To determine the direct variation equation, we need to check if the ratio of green cans (g) to white cans (w) is constant across all the given ratios.
Let's calculate the ratios for each case:
For the first ratio: g = 6 and w = 9
g/w = 6/9
= 2/3
For the second ratio: g = 10 and w = 15
g/w = 10/15
= 2/3
For the third ratio: g = 16 and w = 24
g/w = 16/24
= 2/3
For the fourth ratio: g = 18 and w = 27
g/w = 18/27
= 2/3
Since the ratio of g/w is the same (2/3) for all cases, we can see that the relationship between green cans (g) and white cans (w) is a direct variation
Hence, the direct variation equation is g = 2/3 w, option A is correct.

O Multiply both sides of the equation by 3.
O Subtract 3 on each side of the equation
Divide by 3 on each side of the equation
O Add 3 to each side of the equation
Answer:
Add 3 to each side of the equation
Step-by-step explanation:
The problem is 9+ x-3, so to isolate the x we need to remove the -3, and to do that we need to add positive 3 and whatever you do to one side you must do to the other! hope this helps

George deposits $3,500 at 3.25% interest compounded monthly. What will his ending balance be after 5 years?
Answer:
FV= $4,117.1
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,500
Number of periods= 5*12= 60 months
Interest rate (i)= 0.0325/12= 0.00271
To calculate the Future Value, we need to use the following formula:
FV=PV*(1+i)^n
FV= 3,500*1.00271^60
FV= $4,117.1

Describe the nature of the roots for the equation 49x^2-
28x +4 = 0
O one real root
one complex root
O two complex roots
O two real roots
Answer:
Step-by-step explanation:
One real root
The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
The equation is given as:
[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]
To determine the nature of the roots, we make use of determinants.
The determinant (d) of a quadratic equation is calculated
[tex]\mathbf{d = b^2 - 4ac}[/tex]
Where the quadratic equation is:
[tex]\mathbf{ax^2 + bx + c = 0}[/tex]
By comparison, we have:
[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]
So, we have:
[tex]\mathbf{d = b^2 - 4ac}[/tex]
[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]
[tex]\mathbf{d = 784 - 784}[/tex]
[tex]\mathbf{d = 0}[/tex]
When d = 0, then the function has one real root.
Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
