A function is a set of ordered pairs where a x-value is paired with only one y-value.

As long if the x-value (1) is sharing only one y-value then it makes it a function.

Please someone help me with this question I’m getting stressed and I’m tired.

Nostrana [21]

Answer: (1,4)

Step-by-step explanation:

2x - 3y = -10

y = 4x

2x - 3(4x) = -10

2x - 12x = -10

-10x = -10

x = 1

y = (4)(1)

y = 4

Double Check:

2(1) - (3x4) = -10

2-12 = -10

-10 = -10

I need help with #10!

DiKsa [7]

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

$x+3$

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

$x+3=\frac{3x}{2}$

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

$2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6$

10 mi 6 mi b What is the length of the missing leg? b miles

poizon [28]

Answer:

The length of the missing leg:

b = 8 miles

Step-by-step explanation:

Given

c = 10 mi

a = 6 mi

To determine:

The length of the leg b = ?

For a right-angled triangle, with sides a and b the hypotenuse c is defined as:

$c=\sqrt{a^2+b^2}$

We can find the length of the leg b using the formula

$b=\sqrt{c^2-a^2}$

substituting c = 10 and b = 6 in the formula

$b=\sqrt{10^2-6^2}$

$b=\sqrt{100-36}$

$b=\sqrt{64}$

$b=\sqrt{8^2}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a$

$b=8$ mi

Therefore, the length of the missing leg:

b = 8 miles
