Answer:
Step-by-step explanation:
% = Red / (Blue + red ) * 100
% = 75/(125 + 75) * 100
% = 75 / 200 * 100
% = 7500 / 200 = 37.5% are blue
C.
y=5x-1
To check:
x=0
y=-1
y=5*0-1=-1
x=1
y=4
y=5*1-1=5-1=4
x=2
y=9
y=5*2-1=9
1/3 = 0.333... (repeating)
-- Jovita bought 3.333 cubic yards.
-- She needs 2.5 cubic yards for the flowers.
-- The rest will be left for the veggies.
If she doesn't spill any, that will be
(3.333) minus (2.5) = 0.833... (repeating) cubic yards.
Solve for x in each set of parentheses by setting them to 0:
X -8 = 0
X = 8
X+9 = 0
X =-9
You have two x intercepts (8,0) and (-9,0)
You didn’t list any choices to pick from but it would be either if the ones above.
Answer:
K<-12
Step-by-step explanation:
+ For that, we need the delta negatif.
+ The delta= b^2-4ac=12^2-4(-3)(k)=144+12k<0
Then, 12k<-144 (divise both sides by 12)
we have k<-12
Or an other way:
-3x^2+12x+k=0 (divise both sides by -3)
x^2-4x-k/3=0
x^2-4x+4 -4-k/3=0
(x-2)^2=4+k/3
Now , we need 4+k/3<0, k/3<-4 or k<-12
Hope you understand.
