Answer:

Infinitely many solutions.

Step-by-step explanation:

Let's begin by carrying out the indicated multiplications, which must be done before any addition or subtraction:

2(8r+5)-3=4(4r-1)+11 becomes 16r + 10 - 3 = 16r - 4 + 11.

Subtracting 16r from both sides, we get 10 - 3 = - 4 + 11, or 7 = 7

This is always true, so we can conclude that this equation has infinitely many solutions.

Question<br> Find the distance between the points (-5, 8) and (-3,0).

Temka [501]

To calculate the distance between two points we use this formula:

$\boxed{ \boxed{{d \: = \: \sqrt{(x_2 \: - \: x_1)^{2} \: + \: (y_2 \: - \: y_1)^{2} } }}}$

<h3>We organize the values:</h3>

x₁ = -5
x₂ = -3
y₁ = 8
y₂ = 0

______________________

We apply the values already obtained to the formula to get the distance:

$d \: = \: \sqrt{( - 3 \: - \:( - 5))^{2} \: + \: (0 \: - \: 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: - \: ( - 5))^{2} \: + \: ( - 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: + \: 5) ^{2} \: + \: 64 }$

$d \: = \: \sqrt{ {2}^{2} \: + \: 64 }$

$d \: = \: \sqrt{4 \: + \: 64}$

$d \: = \: \sqrt{68}$

$d \: = \boxed{ \bold{ \: 2 \sqrt{17} \: units}}$

<h2>Answer: </h2>

$\huge{\boxed{ \bold{2 \sqrt{17} \: units }}}$

5/4=y−1/4<br><br>y=_____<br>What is the answer?

Nat2105 [25]

In this equation, you are solving for y. Simply isolate the variable by adding 1/4 to each side. The -1/4 and 1/4 will cancel out on the right side of the equation, leaving only y:

5/4 = y - 1/4

5/4 + 1/4 = y - 1/4 + 1/4

6/4 = y

y = 6/4

Don't forget to simplify y:

y = 3/2
