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
Negative
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

7/27 is already in the lowest form it can go.

You can change it into a decimal though. Divide 7 by 27 to receive the decimal of 0.2592. That process usually needs to be done with a pen and paper. You can find the decimal form of any fraction by dividing the numerator and denominator which is also long division.

A real estate agent earns $2,000 per month plus 5% of the selling price of each housesold. The agent wants to earn more than $60,000 this year. Which inequality represents the
possible combined selling price ( x) of all the houses sold during the year for the real estate
agent to meet his goal?
A. x > 11,600
B. x > 180,000
C. x > 720,000
D. x > 1,160,000

Answers

Given:
2,000 per month
5% of the selling price of each house sold

Agent wants to earn more than $60,000 this year.

2,000 per month * 12mos = 24,000

60,000 - 24,000 = 36,000

36,000 ÷ 5% = 720,000  ⇒ CHOICE C. X > 720,000

The real estate agent must sell a house that is more than 720,000 worth for said agent to earn more than 60,000 this year.



First you get how much he earns which is 24,000 so he would have to have x>180000 because 24000+11600 does not add up to 60000. Hope it helped
