There is no y in this question, however we can solve for t.

1.4t - 0.4(t - 3.1) = 5.8
1.4t - 0.4t + 1.24 = 5.8
t + 1.24 = 5.8
t = 4.56

What is the slope of the line that passes through the points (-2, 7) and (2,-5)?
Deffense [45]

Answer:

Denote that line: y = ax + b

Line passes (-2, 7) and (2,-5):

=> -2a + b =7

=>  2a + b = -5

Add both side of above equations:

=> 2b = 2

=> b = 1

=> a = (-5 - 1)/2 = -3

=> Slope a = -3

Hope this helps!

Landon is saving up to buy a new jacket. He already has $70 and can save an additional $7 per week using money from his after sc
Alexeev081 [22]

For this case we have to:

Let "w" be the variable that represents the number of savings weeks.

We have that Landon's initial amount is $ 70.

We want to know how much money you have after 5 weeks, knowing that you save $ 7 each week, so be "y" the amount of money after "W" weeks:

y = 70 + 7w

After 5 weeks:

y = 70 + 7 (5)\\y = 70 + 35\\y = 105\

Answery = 70 + 7w\\y = 105
