Number 16 find the distance between the two points

Fittoniya [83]

<u>use the distance formula for this which is:
Sqrt[ (x2-x1)^2 + (y2-y1)^2]
If that is hard to read look it up but pretty much its:
Sqrt [(-12 -12)^2 + (-2-5)^2]
Sqrt [(0)^2 + (-7)^2]

Solve the following systems of inequalities and select the correct graph:

zaharov [31]

We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2

So the solution of this system of equation is the coordinate (1, -2)

Elsie pays $8.99 for a one-pound canister of Georgia pecans. Write and solve a proportion to determine the cost of 4

ch4aika [34]

Answer:

$ 35.96

Step-by-step explanation:

Let x be the cost ( in dollars ) of 4 ounces of the pecans,

So, the ratio of the cost and ounces needed = $\frac{x}{4}$

Also, the cost of 1 ounces of pecans is $ 8.99,

Thus, the ratio of the cost and ounces needed = $\frac{8.99}{1}$

Hence, we can write,

$\frac{x}{4}=\frac{8.99}{1}$

Which is the required proportion,

By cross multiplication,

x = 4 × 8.99 = 35.96

Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
