Answer:

$\frac{5}{14}$

Step-by-step explanation:

It's important to note here that fractions are just another way of representing division.

Therefore, $\frac{\frac{1}{4}}{\frac{7}{10}}$ is the same thing as $\frac{1}{4} \div \frac{7}{10}$ .

To divide two fractions, we multiply by the reciprocal.

$\frac{1}{4} \cdot \frac{10}{7}$

We can now multiply the numerators and denominators.

$1\cdot 10 = 10\\7 \cdot 4 = 28\\\\\frac{10}{28}$

We can simplify this fraction by dividing both the numerator and denominator by 2.

$10\div 2 = 5\\28 \div 2 = 14$

So, $\frac{5}{14}$ .

Hope this helped!

x - 2y = 3 5x + 3y = 2 The lines whose equations are shown intersect at which point? (1, -1) (-1, 1) (0, 3/2)

I would solve the first equation for x and then sub that value into x in the second equation. That's the easiest way. x - 2y = 3 solved for x is x = 2y+3. Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2. 13y = -13, and y = -1. Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1. Therefore, your solution to this system is (1, -1), first choice above.

The equation of a circle is given below. (x-0.5)^{2}+(y-3.5)^{2} = 16(x−0.5) 2 +(y−3.5) 2 =16left parenthesis, x, minus, 0, poin

Answer:

<h2>The radius is 4 units long.</h2>

Step-by-step explanation:

The given equation is

$(x-0.5)^{2} +(y-3.5)^{2} =16$

This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.

You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have

$r^{2} = 16\\r=\sqrt{16}\\ r=4$
