Jill is cooking bread. The recipe calls for 4 1/2 cups of flour. She has already put in 4 3/10 cups. How many more cups does she need to put in?
Answer:
im not sure but i think she should not put more because she already put more than it said
Answer: 2/10 more cups
Step-by-step explanation:
Identify the quadratic function that contains the points (-1,-4), (0,0) and (2,-10).
f(x) = 3x^2 - x
f(x) = 3x^2+x
f(x) = - 3x^2+x
f(x) =-3x^2-x
9514 1404 393
Answer:
(c) f(x) = -3x^2 +x
Step-by-step explanation:
Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.
Trying one of the other points in the one of the remaining equations tells you which equation works.
For example, usint (-1, -4) in the third choice, we get ...
f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)
The correct function is the third choice:
f(x) = -3x^2 +x
Question 3 of 25
Find f(-3) for f(x) = 4(2)^x
Please answer this as fast as you can need it for today
Answer: [tex]f(-3)=\dfrac12[/tex]
Step-by-step explanation:
Given: [tex]f(x)=4(2)^x[/tex], which is an exponential growth function.
To evaluate: f(-3)
Substitute x=-3 in the given function, we get
[tex]f(-3)=4(2)^{-3}\\\\=4(\dfrac{1}{2})^3\ [a^{-n}=\dfrac1{a^n}]\\\\=4\times\dfrac1{2^3}\\\\=4\times\dfrac18\\\\=\dfrac12[/tex]
Therefore, the value of [tex]f(-3)=\dfrac12[/tex].

help please, im unsure
Answer:
The value of AM = 43
Step-by-step explanation:
As point M is the midpoint of AB, so
AB = AM + BMAM = BMGiven
AB = 8x - 50
AM = 2x + 9
so substituting AB = 8x - 50 and AM = 2x + 9 in the equation AB = AM + BM
AB = AM + BM
8x - 50 = 2x + 9 + BM
8x - 2x - 50 - 9 = BM
6x - 50 = BM
Thus,
BM = 6x - 59
As
AM = BM
so substituting AM = 2x + 9 and BM = 6x - 59 in the equation AM = BM
2x + 9 = 6x - 59
switch sides
6x - 59 = 2x + 9
subtract 2x from both sides
6x - 2x - 59 = 2x + 9 - 2x
4x - 59 = 9
add 59 to both sides
4x - 59 + 59 = 9 + 59
4x = 68
divide both sides by 4
4x/4 = 68/4
x = 17
Thus, the value of x = 17
Therefore, the value of AM will be:
AM = 2x + 9 = 2(17) + 9 = 34 + 9 = 43
Hence, the value of AM = 43
Verification:
AM = BM
2x + 9 = 6x - 59
2(17) + 9 = 6(17) - 59
34 + 9 = 102 - 59
43 = 43
and
AB = 8x - 50 = 8(17) - 50 = 86

Which graph best represents a function with range -4 ≤ y ≤ 3?
Answer:
3rd one
Step-by-step explanation:
The range of a function is the set of output values the function can take
The graph that represents the range [tex]-4 \le y \le 3[/tex] is graph (b)
The range of the function is given as:
[tex]-4 \le y \le 3[/tex]
The above inequality can be rewritten as:
[tex][-4,3][/tex]
This means that,
The output values start from -4 and ends at 3 (inclusive).The endpoints are closed values at -4 and 3The graph that represents this range is graph (b)

1# Jason is participating in a walkathon. He writes the equation m = 2d + 50 to represent the amount of money he collects from each sponsor for walking d kilometers. What number represents the rate of change?
2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?
Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6

why this worked. Think about what we did, play around with some numbers, try to visualize it.
******HINT: If you have anything you can use to SHOW why it worked, try that. I recommend M&M's or a candy that has color. I suggest showing your number, and whats done to it in one color... 10 and what happens to that in another.*******
Think of a number 1-10
Double it
Add 10 to that number
Divide it by 2
Subtract your original number
Your answer is 5
Answer:
10 divided by 2 equals 5 and your original number added then subtracted would be 0, so 0 + 5 equals 5

Question:Determine if the two triangles are congruent. If they are, state how you know.
Answer: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Step-by-step explanation: So we know that two triangles are congruent if all of their sides are the same-- so side, side, side. We also know they are congruent if we have a side and then an angle between the sides and then another side that is congruent-- so side, angle, side.
