Since the given system has exactly one solution i,e (-10,22) so, the system is consistent and independent.

Step-by-step explanation:

We need to solve the system of equations and identify if the system of equations are consistent and independent, consistent and dependent, or inconsistent.

The system of equations given are:

$y=-x+12\\y=-2x+2$

We can solve using substitution method.

Let $y=-x+12\,\,eq(1)\\y=-2x+2\,\,eq(2)$

Putting value of y fom eq(2) into eq(1)

$-2x+2=-x+12$

Finding value of x:

$-2x+2=-x+12\\-2x+x=12-2\\-x=10\\x=-10$

So, value of x = -10.

Putting value of x in eq(1) to find value of y

$y=-x+12$

$y=-(-10)+12$

$y=10+12$

$y=22$

So, value of y= 22

If a system has exactly one solution then the system is consistent and independent.

Since the given system has exactly one solution i,e (-10,22) so, the system is consistent and independent.

Tema [17]

Answer:

$t=\frac{1}{2}$

Step-by-step explanation:

We want to solve for the value of t in the equation

$4(t+\frac{1}{4})=3$

Since we are trying to make t the subject of the formula (or isolate t)

Divide both sides by 4

$\dfrac{4(t+\frac{1}{4})}{4} =\dfrac{3}{4}$

This gives us:

$t+\frac{1}{4} =\frac{3}{4}$

Next, we subtract $\dfrac{1}{4}$ from both sides

$t+\frac{1}{4}-\frac{1}{4} =\frac{3}{4}-\frac{1}{4}\\t=\dfrac{3-1}{4}=\frac{2}{4}=\frac{1}{2}\\t=\frac{1}{2}$

Jinni opened a bank account. She deposited $87.60 into her account every month for 10 months. She used $25.60 every month to pay

Pavel [41]

Ok to find the answer all you have to do is multiply 87.60*10=876
then do the same for 26.60*10=256 then you subtract 856-256
=620

Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cos

anzhelika [568]

Answer:

14t + 58 ≤ 150

Step-by-step explanation:

If she cannot spend more than what she has, which is 150, the inequality sign has to be "less than or equal to". It's ok if she spends less than 150, but not ok if she spends more, because she doesn't have it to spend.

We know the cost of 1 pair of jeans is 58. Now she wants to make up the difference by getting as many $14 shirts as possible (the number of shirts being our unknown).

That means that the cost of the jeans PLUS the unknown number of shirts cannot exceed 150.

Therefore, the inequality is:

14t + 58 ≤ 150
