What you must do for this case is to find the intersections of the line with the y axis and the x axis.
y = 3x + 9
We have then:
Axis y:
x = 0
y = 3 (0) +9
y = 9
X axis:
y = 0
0 = 3x + 9
x = -9 / 3 = -3
Answer:
The intersections of the line with the y axis and the x axis are nine and minus three, respectively.

Step-by-step explanation:

To find the total amount of tape that Marge used, you can take the measure of each piece ( $\frac{3}{8}$ ) and multiply by the total number of pieces cut (16):

$\frac{3}{8}*\frac{16}{1}=\frac{48}{8}=6inches$

Darius lives in Ohio and pays 5.5% in sales tax. If he just bought a sweatshirt that cost $24, what was the total amount he paid

ollegr [7]

In this question, we are required to find the total amount he paid to buy the shirt.

It is given that sales tax is 5.5 % over the amount paid.

The cost price of the shirt = $ 24.

The total amount will be = Cost price + 5.5 % of Cost price

Total amount paid = $ 24 × 1.055 (i.e. 100 % + 5.5 %)

Total amount = $ 24 + (5.5 % × $ 24)

Total amount paid = $ 24 + $ 1.32 = $ 25.32

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ <span>
Use distributive property:
</span> $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
