Answer:
8/3 cups
Step-by-step explanation:
how many cups of flour does he need for all the cookies he wants to make can be represented by the variable x:
2/3=(1/4)*x
(1/4)*x=2/3
x=(2/3)/(1/4)
x=(2/3)*(4/1)
x=8/3
Thus, Delano needs 8/3 cups of flour to bake all his cookies
There are 12 months, 7/12 have 31 days. You would have a 7/12 probability of choosing one with 31 days if it is random.
Answer:
Slope is -0.6
y-intercept is -4
Step-by-step explanation:
y=mx+b
In order to find zeroes of a function, we will probably want to use our quadratic formula.
-b±√b^2-4(a)(c)/2a
If we know our values, we can plug it in.
Our values:
A=1 (Since there is no number in front of x, it is an assumed 1)
B=17
C=72
Now, We can plug it into our formula.
BE SURE TO PUT PARENTHESIS AROUND ALL TERMS!
-(17)±√(17)^2-4(1)(72)/2(1)
Now we can type it into a calculator!
When we plug it into the formula. It gives us two real solutions (or zeroes) which are represented as:
-8 & -9.
