The graph shows the temperature of a liquid that is being heated during an experiment. Three of the statements are true. Which is NOT?
Temperature (°C)
(6.5, 26)
0
Time (min)
CLEAR
CHECK
The temperature of the liquid is increasing at a constant
rate
At this rate, the temperature will rise 60° in a quarter hour.
0
The temperature of the liquid changed at a unit rate of 4°
per minute
At this rate, it would take less than 10 minutes for the
temperature of the liquid to rise 52°

so then what are you asking?

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
