4y + x = 12, 2x = 24 - 8y Solve by Substitution

Ann [662]

Answer: Undefined

Step-by-step explanation:

4y+x=12, 2x=24-8y

Isolate x by subtracting 4y

4y+x=12

x=12-4y

Plug the equation for x in to anywhere you see the variable x in the other equation

2(12-4y)=24-8y

Distribute 2

24-8y=24-8y

Get the variables on one side so add 8y (cancels out)

24=24

Can’t solve its undefined

Each day her goal is to make 4 more baskets than she made thr day before. If she makes 10 baskets the first day and meets her go

irina [24]

Answer:

Janelle will make 62 baskets on 14th day.

Step-by-step explanation:

Given,

Number of goals on 1st day = 10

We need to find the number of goals on 14th day.

Solution,

Since Janelle made 10 goals on 1st day and want to make 4 more basket from the day before.

So we can say that;

$a_1=10$ and $d=4$

And also $n=14$

here $a_1$ = first term

d = common difference

n = number of terms

Now we apply the formula of A.P.

$T_n=a_1+(n-1)d$

now substituting the given values, we get;

$T_{14}=10+(14-1)4\\\\T_{14}=10+13\times 4\\\\T_{14}=10+52 =62$

Hence Janelle will make 62 basket on 14th day.
