Answer:

Alright i'm just going to assume your doing both of them one at a time.

y + 2x = - 1: So Alright Graph using the slope and y-intercept

Slope: - 2

Y-intercept: - 1

And the other

- 3x = 16: same as well So the Answer to this is Except solve for x by simplifying both sides of the equation, then isolating the variable

Exact form: x = - 16/3

Decimal form: x = - 5.3 Well Hope this helps :)

Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the \$j$jdollar sign, j fare a

Galina-37 [17]

Answer:

$\$ (\frac{j+15}{3} )$

Step-by-step explanation:

There were three friends and the total fare was $j

Each of the friends pays $\$ (\frac{j}{3} )$ for their cab fare.

Since Angela also paid a $5 Tip

Total Amount Paid by Angela = Share of cab fare + Tip

$\$ (\frac{j}{3} ) + \$5$

We can simplify this further by taking the LCM.

$\$ (\frac{j}{3} ) + \$5=\$ (\frac{j+15}{3} )$

The total amount paid by Angela therefore is : $\$ (\frac{j+15}{3} )$

Y= (x - 2)²-7 how do I graphic this<br>

WITCHER [35]

Hmmm it would be kind of hard to graph as it will be a curved line but the middle of the line would be at (2,-7). Not (-2,-7).

And it will be curving upwards, meaning it will start by going down and end by going up.

Hope this helps some.
