Awe, okay, I learned how to do this. Direct variation equation y=kx. So, I believe you're asking for help on 9 so here, y=k/X=k=y/x =-5/2. Now, plug back the fraction into y=kx like this, - 5/2(8) since X is 8 in this case, which equals - 20. What was just solved was your y for when X is 8.
Answer:
y= -1/3x +5
Step-by-step explanation:
Using the equation y=mx+b
you know <em>m</em> (slope), which is -1/3
you also know your <em>b</em> which is 5
You get y= -1/3x+5
An animal shelter spends $3.50 per day to care for each bird and $4.00 per day to care for each cat. Katherine noticed that the shelter spent $103.50 caring for birds and cats on Friday. Katherine found a record showing that there were a total of 28 birds and cats on Friday. How many birds were at the shelter on Friday?
No. of birds X
No. of cats 28 - X
103.50 = 3.50X + 4.00(28 - X) = 3.5X + 4x28 - 4X = 3.5X + 112 - 4X
O.5X = 112 - 103.5 = 8.5
X = 17
No. of birds 17
No. of cats 28 - X + 28 - 17 = 11
Check: $3.5 x 17 + $4 x 11 = $59.5 + $44 = $103.50
Answer:
x=23
Step-by-step explanation:
STEP 1. To find x-intercept/zero, substitute y=0.
0= 6x2+x-35
STEP 2. Calculate the difference.
0=-23+x
STEP 3. Move the variable to the left- hand side and change its sign.
-x=-23
STEP 4. Change the signs on both sides of the equation.
x=23
