Answer:

$5\sqrt{2}$

Step-by-step explanation:

well we use the distance formula

$\sqrt{(4^{2}+(-4)^2 )+(3^2+(-3)^2)}\\ =\sqrt{32+18} \\=\sqrt{50}\\ =5\sqrt{2}$

so that's the length of the radius

Select the equation in which the graph of the line has a negative slope and the y intercept equals -5

tatuchka [14]

Answer:

Step-by-step explanation:

Next time, please share the possible answer choices.

Since the slope and y-intercept are given here, we can immediately write out the slope-intercept form of the equation of this line:

y = mx + b becomes y = -1x - 5, where I have arbitrarily chosen the negative slope -1.

Which equation has a solution of n = 4?

Allushta [10]

Answer:

D. 7n = 28

Step-by-step explanation:

Let's substitute 4 for n in each equation to check if it the resulting equation is correct:

$6+n=24\\ 6+4=24\\ 10\neq 24\rightarrow \text{Incorrect!}$

$5n=54\\5(4)=54\\20\neq54\rightarrow\text{Incorrect!}$

$12-n=16\\12-4=16\\8\neq16\rightarrow\text{Incorrect!}$

$7n=28\\7(4)=28\\28=28\rightarrow\text{Correct!}$

Therefore the answer is D
