1) A negative rate of change is when the slope is a negative number...so, lets look for the slope that is negative. 

1.  2x - 5y = -15 
   -5y = -2x - 15
    y = 0.4  + 5
Positive 

2.  y = -4x + 9
    Negative

3. -16 - - 10 / 4 - 2 = m
m = -6/2
m = -3
Negative

4. 11 - 15  / -2 - - 3
     -4 / 1 = -4
m = -4
Negative 

Done with number one! :P

2) The greatest rate of change would be the steepest line, so lets find that!

From the answer choices, '5' has the largest slope. 

Answer: B) y = 5x + 4

3) Now, again, we must find the greatest rate of change. 

A) 6 - 3 / 4-3
m = 3/1
m = 3

B) m = 6

C) m = -2

We see that 6 is the greatest. 

Answer: B) 

4) Greatest start value would be the y intercept.

C has the greatest start value, because it is 2, so that would be the answer. 

Answer: c

5) y=16*1 + 560
y=16+560
y=576 

x = 1
y = 504

Calories of sugar would be >>>>>>>>>>>>>  576
Calories in honey would be >>>>>>>>>>>>>> 504

I HOPE THIS HELPED YOUUUUUU

rate of change is also knkown as slope which is found by
(y2-y1)/(x2-x1)=slope if you know 2 points/ordered pairs
aos, if x incheases while y decreases then slope is negative
when x increases while y increases then slpe if positive
also, if you can convert to y=mx+b, m=slope
another thing if you have ax+by=c then slope=-a/b

so first one
2x-5y=15
a=2
b=-5
-2/-5=2/5
slope=2/5
positive

next
y=-4x
-4 =slope=negative


x increases while y decreases
negative

x increases while y decreases
negative


so
Positive
Negative

A. 6x-3y=12
sloope=-6/-3=2

B. y=5x+b
slope=5

C. (8-2)/(3-1)=6/2=3
sloope=3

D. goes up 4 units and goes right 1 unit, 4/1=4
sloope=4


5 is greates
B is the answer









A. (6-3)/(4-3)=3/1=3
slope=3

B. y=4+6x
slope=6


C.12x+6y=18
slope=-12/6=-2

D. goes down 5 units as it goest 1 uniit to right aka -5./1
slope=-5


greatest is 6
B is answer











the starting value I would guess si when x=1 what is the greats y value

look at each
first one
A. x=1 and =-3

B.y=3x-8
y=3(1)-8
y=3-8
y=-5

C. 8x+4y=16
8(1)+4y=16
8+4y=16
4y=8
y=2

D. at 1 unit to right it is 1 nit up so y=1


greatest is  2 or C





so just subsitute 1 for x since x represents how many teaspoons
y=16(1)560
y=16+560
y=576 caloris for 1 sugar teaspoon

for honey, just read off the graph
for when x=1
y=504

so calores of sugar=576
calories in honey=504

A recipe uses 1 1/4 cups of oil to make 20 servings. If the same amount of oil is used for each serving, how many servings can be Made with one gallon of oil ?

Answers

Answer:

Step-by-step explanation:

1 1/4 (or 1.25) cups to 20 servings = 1 gallon (16 cups) to x servings

 1.25        16

--------- = --------  cross multiply

 20           x

(1.25)(x) = (20)(16)

1.25x = 320

x = 320/1.25

x = 256 servings <===

Why do whole numbers raised to an exponent get greater well fractions raised to an exponent get smaller

Answers

Because when you raise an exponent on a fraction, it is basically dividing into itself.  Imagine 1/3 multiplied my 3 (Ans is 1), the fractions aren't whole numbers so when they multiply into another number, it uses division

How do you divide 33 by 50

Answers

Long division works from left to right. Since 50 is a 2-digit number, it will not go into 3, the first digit of 33, and so successive digits are added until a number greater than 50 is found. In this case 2 digits are added to make 33undefined. Note the other digits in the original number have been turned grey to emphasise this and grey zeroes have been placed above to show where division was not possible with fewer digits.
The closest we can get to 33undefined without exceeding it is 0 which is 0 × 50. These values have been added to the division, highlighted in red.
In this case the target of 33 is less than 50 so a division is not possible. Put a 0 in the answer to show this and 0s below the 33.
Leaving out the 0 from the answer line when this occurs is one of the easiest mistakes to make with long division.
