Answer:
x=-1
Step-by-step explanation:
y=4x+10
y=3x+9
-----------
4x+10=3x+9
4x-3x=9-10
x=-1
16x +23
-16 -16
X = 7....................

Step-by-step explanation:
<u>Surface Area</u>
The surface area of a cylinder of height h and radius r is given by:

It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:

The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.
Now we calculate the side area of the can:


We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:

The total area of the label is:

The area of the label is 
Answer:
3/4
Step-by-step explanation:
m=y2-y1/x2-x1
11-(-7)=18
19-(-4)=23
18/23
18/23 in simplest form is 3/4
hope this helps :3
if it did pls mark brainliest
