Answer:
x = -9/5
y = 16/5
Step-by-step explanation:
-3x-2y=-1 first you need to multiply the numerator by 3 so when adding
4x+6y=12 the y's cancel and you get a single variable
3(-3x-2y=-1) —> -9x - 6y = -3 then you add the like terms
4x+6y=12 —> 4x + 6y = 12
(-9x+4x) + (6y - 6y) = (-3 + 12)
-5x = 9 then you divide by -5
x = -9/5
then you plug this in to either equation
4(-9/5) + 6y = 12
-36/5 + 6y = 12 then you add 36/5 to both sides
6y = 96/5 then you divide by 6
y = 16/5
Answer:
a right cylinder with a radius of 7 inches
Answer:
Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = 
<em>Given circumference of the ring is 
</em>
<em>Now solving for the radius gives us:</em>
We know that area of a circle is 
, substituting the value of r we found, we get the area as:
area (A) = 
Hence the Area (A), in terms of 
is 
The option that describes h(x) is B. The function h(x) is increasing on the interval (5, ∞).
<h3>What is a function?</h3>
In mathematics, a function simply means a relation between the inputs and the outputs.
In this case, the information given is that h(x) is 2 times the square root x minus 5. The square root of the negative number cannot be taken, therefore, the domain of the function is restricted.
Since the domain is restricted, the function is increasing. Therefore, the function h(x) is increasing on the interval (5, ∞).

Ooo.
Fun.
So the equation: y = 1/4x = 3 is in slope-intercept form where, y = mx + b.
'm' is the slope and 'b' is the y-intercept.
Knowing this, we can easily conclude that Choice A is the correct answer.
Why?
Well, just look below.
y=1/4x + 3
y = mx + b
We simply match up the values with the slope-intercept formula and see that 3 falls under the y-intercept category, and m, which always equals slope is replaced by 1/4.
Thus, A is the correct choice.
