Y=mx+b is the equation we must fill out, with x and y being their respective coordinates, m being the slope, and b being the y-intercept. The y intercept will be at (0, y), and the beginning of this problem already gives us the y-intercept: -4.

We now know y=mx-4. To find the slope, m, we’ll plug in one of the coordinates: (5, 1). The new equation is 1=m(5)-4. Solve this to get 5=m(5), and then m=1.

Now that we know the slope and y-intercept, we can conclude that the equation is y=x-4.

Someone please help me answer this!!
lianna [129]

Answer:

7.1 units is the answer

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(6-1)^2 + (2-7)^2}\\\\d=\sqrt{(5\\)^2+(-5)^2} \\\\d=\sqrt{25+25} \\\\d=\sqrt{50} \\\\d=7.071..

Rounding off,

d = 7.1 units

I GIVE BRAINLIEST PLEASE EXPLAIN<br> What is the square root of 100????<br> BRAINLIEST
vovangra [49]
Every positive real number has TWO<span>square roots;  One is positive and one is negative. They are opposites of each other. </span>
 
10 is a square root of 100 because (10)(10) = 100, and  ̶ 10 is also a square root of 100 because  ( ̶ 10)( ̶ 10) = 100.

In general, “a” is a square root of “b” if a² = b, where “a” is a real number and b ≥ 0.
 
In conclusion:
<span>  √(100) = </span>10<span> (the </span>positive<span> square root of 100)  </span>and<span>   </span>
<span> ̶  √(100) =   ̶  (10) =  </span>̶ 10<span> (the </span>negative<span> square root of 100)</span>

nikdorinn [45]

Answer:

D.) 0.9990

Step-by-step explanation:

Given :

Number of questions = 10

True or False questions ; probability of success, p = 1/2 = 0.5

Using binomial distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Probability of getting atleast one correct answer :

P(x ≥ 1) = p(1) + p(2) +... P(x = 10)

Using a binomial probability calculator :

P(x ≥ 1) = 0.9990

Mariana [72]

\qquad \textit{perfect square trinomial} \\\\ (a\pm b)^2\implies a^2\pm \stackrel{\stackrel{\text{\small 2}\cdot \sqrt{\textit{\small a}^2}\cdot \sqrt{\textit{\small b}^2}}{\downarrow }}{2ab} + b^2 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ x^2 \pm \stackrel{\stackrel{2\sqrt{x^2}\sqrt{c^2}}{\downarrow }}{6x} +c^2~\hspace{10em}6x=2\sqrt{x^2}\sqrt{c^2}\implies 6x=2xc \\\\\\ \cfrac{6x}{2x}=c\implies 3=c\implies 9=c^2~\hfill \boxed{(x\pm 3)^2}
