As part of a screening process, computer chips must be operated in an oven at 125 °C. Ten minutes after starting, the temperature is 55 °C. After 15 minutes, the temperature is 70 °C. Write a function modeling the temperature of the oven in the form y = mx + b.

c

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
