a is given to us so just plug a into the first equation:

b-3 - 3b =9

Add 3 to both sides:

b-3b=12

Combine like terms:

-2b=12

Divide by -2 to get b by itself:

b=-6

The only answer with b as -6 is the first one, (-9,-6)

The first one, (-9,-6) because if you were to plug it in the answers would equal therefore, the equation is true.

From the graph we observe:  
If x = 0 then y = 1/2    (because  e⁰ = 1)

\displaystyle \bf \\
\Longrightarrow~~\boxed{\bf y =  \frac{1}{2} e^x}

Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they hav
horsena [70]

Answer:

Franco has 66 baseball cards.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of baseball cards that Franco has.

y is the number of baseball cards that Juan has.

Franco has 18 fewer baseball cards than Juan.

This means that:

x = y - 18

Also:

y = x + 18

Together they have 150 baseball cards.

This means that:

x + y = 150

Since y = x + 18

x + x + 18 = 150

2x = 132

x = \frac{132}{2}

x = 66

Franco has 66 baseball cards.

What is the meaning of the t-intercept of the altitude graph? The y-intercept?
Gnom [1K]

Answer: Hello mate!

We know that you have a graph of y vs t, and we know that this is an "altitude" graph.

Then we can assume that the y represents the altitude, and t represents the time, and this graph shows the altitude of something as a function of the time.

the t-intercept means that the graph passes through the y-axis, this means that, in this point, y is equal to zero:

Then, at the t-intercept, we have y = 0, which means that at this time (where is the intersection) the altitude is equal to zero.

The y-intercept means that the graph passes through the y-axis, where t = 0

this is the initial value of the altitude, where t = 0 usually denotes the time where we start to measure.

Paul is going to buy a collectible vintage painting from the local art gallery. The painting is priced at $600 in the gallery. T
Anuta_ua [19.1K]
Given:Painting priced at $600.
If paid using credit card and in installment basis.$600 x 16% = $96 interest on credit card balance$600 + $96 = $696 total debt$696 ÷ 12 months = $58 monthly payments
If paid using cash from cash advance.$600 x 5% discount = $30$600 - $30 = $570$570 x 32% = $182.40 interest on cash advance$570 + $182.40 = $752.40$752.40 ÷ 12 months = $62.70 monthly payment
It is cheaper for Paul to buy the painting using his credit card. He will only pay $58 per month on his credit card provider compared to the $62.70 monthly bill if he used cash advance.

Hope this helped☺☺
