BRAINLIEST PLS HELP ASAP LINEAR EQUATIONS

Musya8 [376]

Answer:

first one

Step-by-step explanation:

Tracey bought 10 movies

some cost 13 and the others 16

Let x be the movies that cost 13 and y ones that cost 16

we can state that

x+y = 10

since Tracey both ten

13x+ 16y = 139

since the total price is 139

so the system is :

$\left \{ {{13x+16y=139} \atop {x+y=10}} \right.$

Terri graphed a system of linear inequalities. Which ordered pairs are a part of the solution set for this system of linear ineq

Oduvanchick [21]

Answer: (2, -4) and (7, -1)

Step-by-step explanation:

Ok, the solutions of the system of inequalities are all the points that lie on the blue shaded part of the graph or in the solid line.

So, in order to see if the points are solutions of the system, then you need to locate the point in the graph and see if it is inside the shaded region or in the solid line (only in the segment that "touches" the shaded region).

Now, we want to find the equation of the solid line, we can see that it passes through the points (0, 6) and (6, 0)

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Then, in this case, the slope is:

a = (0 - 6)/(6 - 0) = -1.

And to find the value of b, we have that when x = 0, y = 6.

y = 6 = -1*0 + b

6 = b

The equation is:

y = -1*x + 6

(-1, 5) is not in the blue region nor in the solid line, so this is not a solution.

(7, - 1) this point is near the solid line, let's test it:

y(7) = -1*7 + 6 = -1

So the point (7, -1) is on the solid line, and is the other solution of the system.

My home work says to solve this 9 3 2 1 =1

Norma-Jean [14]

9 divided by 3 is 3

3 minus 2 is 1

1 divides by 1 is 1

9/3=3
3-2=1
1/1=1

I hope this helped

Ryan has deposited $100 into a retirement account at the end of every month for 50 years. The interest rate on the account is 1.

Andre45 [30]

Answer:

future payment is $77056.92

total interest is paid after 45 year is $23056.42

Step-by-step explanation:

Given data

payment (P) = $100

No of installment (n) = 12

rate of interest ( r ) = 1.5 % i.e. = 0.015

time period (t) = 45 years

to find out

future payment and interest after 45 year

solution

we know future payment formula i.e. given below

future payment = payment × $(1+\frac{r}{n})^{nt} - 1) / (r/n)$

now put all these value in equation

future payment = $ 100 × $(1+\frac{0.015}{12})^{12*45} - 1) / (0.015/12)$

future payment = $ 77056.92

payment paid in 45 year @ $100 total money is paid is 45 × 12 × $100 i.e. = $54000

total interest = future payment - money paid

total interest = $77056.42 - $54000

total interest = $23056.42
