Answer:
Y= -1/3x +2.5
step-by-step explanation:
first I reconfigured the given equation: x+3y=15
-x+x+3y=15 -x Subtracted x from both sides
3y=15-x Simplify
3y/3=15-x/3 Divide both sides by 3
y=-1/3x+3 Simplify
I turned it into y=-1/3x+5
then I translated the line up and down to find what point crossed (6,1)
The proper value for B in y=mx+b was 2.5
Try using Desmos online calculator it really helps
Hope this helped :)
Answer:
Total 1352 different arrangements can be formed.
Step-by-step explanation:
Total number of letters is 26 (a to z).
We need to find the arrangements of 3 letters
It is given that the first letter must be w or k and repetition of letters are allowed.
Since first letter can be w or k, therefore the possibilities for first letter is 2.
Repetition of letters are allowed and any letter can be formed in place of second and third letter.
So, the possibilities for second letter is 26 and possibilities for third letter is 26.
Total possibilities of arrangements of 3 letters is
Therefore total 1352 different arrangements can be formed.
Your problem is giving you d in terms of t, meaning that it is asking if we replace t with 11, what would d be?
When a number is right in front of a variable, they are being multiplied
So if t is 11, and the problem shows 11t, we replace the t with 11 and put parentheses around it
d = -20 + 11t
d = -20 + 11(11)
d = -20 + 121
d = 101
And there you have it! Your final answer is d = 101!
Practice pre-algebra and plugging in numbers into equations! Having mastery over the basic math functions and rules, as well as Order Of Operations, makes all of this so much easier!
I recommend that you watch Khan Academy videos and practice problems on there! It is a great resource! What you are learning would most likely fall under pre-algebra!
ANSWER
Y-intercept: 3000
Slope:-275
Linear equation:y=-275x+3000
EXPLANATION
The straight line touches the y-axis at
(0,3000).
The y-intercept is b=3000
The line also passes through (2,2450).
The slope is calculated using the formula,
The slope is -275.
The linear equation is given by:
