200 weeks . Use the equation 100+20x=y and 50+30x=y on Desmond to show where the line intersect and it is 200
Let's break this problem down and solve it step-by-step.
STEP-BY-STEP SOLUTION:
Keep in mind the following:
Two positives together or two negatives together = positive
One positive and one negative together = negative
Okay, now let's begin solving the problem.
= ( 8 ) ( - 5 ) + ( - 7 ) ( 3 )
First we will multiply the brackets together.
= ( - 40 ) + ( - 21 )
Next we will remove the brackets and change the positive ( + ) and negative ( - ) symbol into just a negative symbol, as a positive and negative always equals a negative as stated previously.
= - 40 - 21
Now we will simply subtract 21 from - 40 to achieve our final answer.
= - 61
Hope this helps! :)
Have a lovely day! <3
To find the
intercept, set
. By this I refer to the following procedure.
x-intercept: Set
, then you're left with
. Then the x-intercept is
.
y-intercept: Set
, then
. The y-intercept is
.
z-intercept: Set
, then
. The z-intercept is

Sugar Flour
1 1.5
2 3
3 4.5
4 6
To find any number, create a ratio of 1/1.5=cups of sugar/cups of flour then cross multiply and solve to get any answer you may need.
