As per the attached graph we observe that the constant rate of change is 9 as each step of horizontal change corresponds to 9 steps of vertical change

<u>It is found as the division below:</u>

(9-0)/(1-0) = 9/1 = 9

Point (0, 0) indicates the start point

Point (1, 9) indicates the cost of 1 t-shirt

A fluid initially at 100◦C is placed outside on a day when the temperature is −10◦C, and the temperature of the fluid drops 20◦C

IRISSAK [1]

Answer:

Temperature drops to -10 deg C after 5.5 minutes and remains at that temperature.

Step-by-step explanation:

$t_{1} = 1, T_{1} = 80\\\\t_{2} = 2, T_{1} = 60\\\\t_{3} = 3, T_{3} = 40\\\\t_{4} = 4, T_{4} = 20\\\\t_{5} = 5, T_{5} = 0\\\\t_{6} = 6, T_{6} = -10\\\\t_{7} = 7, T_{7} = -10\\\\t_{8} = 8, T_{8} = -10\\\\t_{9} = 9, T_{9} = -10\\\\t_{10} = 10, T_{10} = -10\\$

Please I have 5 minutes! <br>solve 1/5^2x+10 = 25^3x

TiliK225 [7]

Answer:

-5(3x+4) = 25

-15x-20=25

-15x=25+20

-15x=45

>then divide both side by -15

Therefore: X=-3

4(x+2)-3(2x-4)=10

4x+8-6x+12=10

-2x+20=10

-2x=-10

> divide both sides by -2

Therefore: x= 5
