Answer:

Step-by-step explanation:

3x-y=14

4x+y=21

add

7x=35

x=35/7=5

4×5+y=21

y=21-20=1

so (5,1 ) is the solution.

Top left is the answer I believe

Question 9 I didn’t mean to click on one

Zinaida [17]

<h3>Answer: Choice A</h3>

You selected the correct answer choice.

The given equation y = 3x-5 is in the form y = mx+b with slope m = 3.

Parallel lines have equal slopes but different y intercepts. So any parallel line will also have slope m = 3 (the b value must be different though).

Answer:

$\huge\boxed{\bf\:2\sqrt{5} \:\: units }$

Step-by-step explanation:

We have a figure given in the shape of a square with a diagonal (x) passing from one edge to another. We need to find the measure of its diagonal if the side of the square is $\sqrt{10}$ units.

We know that, a square has all equal sides. Then, all the sides of the square will be equal to $\sqrt{10}$ units.

Now, let's find the diagonal.

To find the diagonal of a sqaure from one of its sides, we need to know the formula ⟶ Diagonal = side $\bf\:\sqrt{2}$ .

By using this formula,

$Diagonal (x)\\= side *\sqrt{2} \\= \sqrt{10} *\sqrt{2}\\ = \sqrt{5*2*2} \\= \boxed{\bf\:2\sqrt{5} \:units}$

→ The diagonal of the square = 2√5 units.
