Diego has $10 and begins saving $2 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $50 and begins spending $2 per week on supplies for her art class. Is there a week when they have the same amount of money?Write an equation and answer.

no

Step-by-step explanation:

the easiest way to find out is to plot these on a graph

for Diego's function, we will write the total amount of savings (or his goal) = the amount hes saving multiplied by the weeks he saves + the amount he started with

y = 2x + 10 (in blue in attached file)

same with Lin

y = 2x + 50 (in red in attached file)

if the lines cross at any point, then that point on the two lines is the same value of x AND y, otherwise, one or the other is a different value

beings as these two lines have the same rate of change, they will not cross, meaning that neither will have the same amount if the rate continues

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
