Step-by-step explanation:

for each top equation, there is a y value and an x value. You could plug in the bottom equation for y in the top equation since y=5x+23. Then you do order of operations and get your y-value. Then you do order of operations again and get your x-value. then its ordered pair, (x,y)

Name three points that are collinear. Assume angle TSR is not a straight angle.

skelet666 [1.2K]

Answer:

TS, SR, and TR are all co-linear

Step-by-step explanation:

Regardless of where the points lie, you can connect a line segment from point T to point S, so TS are co-linear

The same goes for point S to point R

The same goes for point T to point R

The definition of a line is the shortest distance through 2 points in space, so you can make a line between any 2 points.

The following list shows the items and prices for a restaurant order. Calculate the total amount if there is an 8% tax and the c

Andreas93 [3]

Answer:

Option B

The total amount is $63.31 if there is an 8% tax and the customer leaves a 20% gratuity.

Step-by-step explanation:

Given:

List of items Prices

1 Appetizer $8.59

2 Entrees $15.99 each

1 dessert $4.69

2 drinks $2.10 each

Total amount for the food order came to, $\left ( 1\times \$ 8.59 \right +2\times \$15.99+1\times \$4.69+2\times\$2.10)$ $=\left (\$ 8.59 \right + \$31.98+ \$4.69+\$4.20)$ =$49.46

Since the restaurant charges 8% as a tax on the total bill.

First, figure out the tax, 8% of $49.46 $=0.08\times $49.46$ =$3.9568

Now, figure out the Customer leaves a gratuity, 20% of $49.46 $=0.20\times \$49.46$ = $\$9.896$

The total amount( including 8% tax and 20% gratuity )=$49.46+$9.896+$3.9568=$63.3128 $\approx \$63.31$
