Answer:

(4, 12)

Step-by-step explanation:

Hello!

Since two of the equations are linear we can use those to find where all three intersect

The two linear equations are y = 2x+4 and y = x+8

We know this because they do not have a square value and they are in slope intercept form which is linear.

Since y is equal to both of them that means they are equal to each other

2x + 4 = x + 8

We can now solve it algebraically

Subtract x from both sides

x + 4 = 8

Subtract 4 from both sides

x = 4

We now have the x coordinate

To find y we put the x coordinate into either of the two original equations and solve to y

y = 4 + 8

y = 12

We now know the point is (4, 12)

The answer is (4, 12)

Hope this helps!

20 Fuji apples cost $12. How many Fuji apples can you buy for $3?
ryzh [129]

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5

3/28 of the animals are birds. 4/15 are birds of prey. What fraction of the animals are birds of prey.
vova2212 [387]
Let's call animals "a", and birds "b", birds of prey, "p"

so, b=\frac{3}{28} a

and p=\frac{4}{15} b
what;s the relation of p to a?

we substitude b into the last one:

and p=\frac{4}{15}* \frac{3}{28} a
so:
p=\frac{4*3}{15*28} a

p=\frac{4*1}{5*28} a


p=\frac{1*1}{5*7} a

p=\frac{1*1}{35} a

which is the answer!
