Answer:

x=2, y=1

Step-by-step explanation:

13x-12y=14

11x-4=18y or 11x-18y=4

13x-12y=14 /*3

11x-18y=4 /*(-2) then

39x - 36y=42 (1)

-22x+36y=-8 (2)

(1)+(2) 17x=34

-22x+36y=-8

x=34/17

-22x+36y=-8

x=2

-22*2+36y=-8

x=2

-44+36y=-8

x=2

36y=-8+44

x=2

36y=36

x=2

y=36/36

x=2

y=1

I just need help with first 2! Show work please it’s due soon and round answers to the nearest tenth !!!
natima [27]

Answer:

1. To find the volume of a cylinder you'll need to use the formula V = pi(r)^2(h)

V = pi(4)^2(6)

V = 301.59

Rounded* = 301.6

2. A beach ball is a sphere, so we're going to use the formula 4/3pi(r)^3

4/3pi(18)^3

D =  24429.02

Rounded* = 24429.0

I cant read the last one completely, hope this helps.

A town has a population of 5000 and grows at 4% every year. What will be the population after 7 years, to the nearest whole numb
Rudiy27

I think this is.. ↓

grows 4% at every year

after 7 years ↓↓

4 × 7 = 28

A town has a population of 5000

28% of 5000 = 1400

5000 + 1400 = 6400


after 7 years, town has 6400 population = after 7 year grows 28%

TBH, i am not sure what im doing. Here is a pic of the question.
tatyana61 [14]

Answer:

  7

Step-by-step explanation:

The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.

Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.

Now, the problem becomes evaluating g(2).

You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.

Now, you know ...

  g(h(-3)) = g(2) = 7
