Write an equation in standard form of the line passing through the points (1,5) and (3, 13).
Answer:
[tex]y - 4x = 1[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (1,5)[/tex]
[tex](x_2,y_2) = (3,13)[/tex]
Required
The equation of the line
Back up:
First, calculate the slope(m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{13-5}{3-1}[/tex]
[tex]m = \frac{8}{2}[/tex]
[tex]m = 4[/tex]
Calculate the area using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y- 5 = 4(x - 1)[/tex]
[tex]y- 5 = 4x - 4[/tex]
Collect Like Terms
[tex]y - 4x = 5 - 4[/tex]
[tex]y - 4x = 1[/tex]

PLEASE HELP ME ANSWER The probability that Scott will be late for work is 0.15. In a year Scott works for 240 days. Work out the expected number of days that he will be late......
Answer:
36 days
Step-by-step explanation:
Given
[tex]p = 0.15[/tex] -- probability of coming late to work
[tex]n = 240[/tex] -- number of days
Required
Determine the expected number of days of coming late (E(x))
This is calculated using:
[tex]E(x) = np[/tex]
[tex]E(x) = 240 * 0.15[/tex]
[tex]E(x) = 36[/tex]
The expected number of days is 36

Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?
Answer:
12.56 inches
Step-by-step explanation:
Circumference: C = 2*pi*r
I will be using 3.14 in place of pi
Divide the diameters by 2, so 3 for Zoey and 5 for Sam
Multiply (2*3.14*3) and (2*3.14*5)
For Zoey you get 18.84 and for Sam you get 31.4
31.4-18.84= 12.56 in difference

9y-8x=63 How do I convert this into slope-intercept form?
Answer:
turn it into y=mx+b
Step-by-step explanation:
get y alone
add 8x to both sides
9y=63+8x
divide both sides by 9
63/9=7 8x/9= [tex]\frac{8x}{9}[/tex]
simplify
y=[tex]\frac{8}{9}[/tex]x+7Answer:
y = 0.8x + 7 or
y = [tex]\frac{4}{5}[/tex]x + 7
Step-by-step explanation:
The slope intercept formula is: y = mx + b
9y - 8x = 63
+8x +8x
= 9y = 63 + 8x
9y/9 = 63/9 + 8x/9 ←
We're getting rid of the 9 beside the y, so we have to divde every number by 9.
= y = 0.8x + 7 if you want the 0.8 as a fraction, it'll be [tex]\frac{4}{5}[/tex]

Answer:
n=13 s=-6
Step-by-step explanation:
Hope this helps :)
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
32=4(n−5);−s+11=17
Rewrite equations:
32=4n−20;−s+11=17
Step: Solve 32=4n−20 for n:
32=4n−20
32+−4n=4n−20+−4n(Add -4n to both sides)
−4n+32=−20
−4n+32+−32=−20+−32(Add -32 to both sides)
−4n=−52
−4n/ −4 =/ −52/ −4
(Divide both sides by -4)
n=13
Step: Substitute 13 for n in −s+11=17:
−s+11=17
−s+11=17
−s+11+−11=17+−11(Add -11 to both sides)
−s=6
−s/ −1 = 6/ −1
(Divide both sides by -1)
s=−6
Answer:
n=13 and s=−6

Solution:
The greatest of Winnie's even numbers is $2\times 30 = 60,$ so her sum is
\[2+4+6+\cdots + 58 + 60.\]For Grogg's sum, there are five odd numbers between $0$ and $-10$, five between $-10$ and $-20$, and so on, so Grogg's sum is
\[(-1)+(-3)+(-5)+\cdots+(-57)+(-59).\]
We could compute these sums separately and find their difference, but instead, we'll look for a clever way to regroup to compute the difference
\[(2+4+6+\cdots +58+60)-((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Noting that Winnie's list steps up by 2 at each term while Grogg's steps down by 2 at each step, we write Winnie's list backwards, so that each list goes down by 2 at each step:
\[(60+58+56+\cdots + 4+2) - ((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Now, we see that the difference between a term in Winnie's backwards list and the corresponding term in Grogg's list is always the same:
\begin{align*}
60-(-1) &= 61,\\
58-(-3) &= 61,\\
56-(-5) &=61,\\
\vdots&\\
2-(-59) &= 61.
\end{align*}There are 30 such differences, so Winnie's sum is $30\times 61 = \boxed{1{,}830}$ greater than Grogg's sum.

Q10
∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°Q11
∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°Measure of angles for figure 1:
∠1=36∠2=56∠3=124∠4=88∠5=36Measure of angles for figure 2:
∠1=35∠2=145∠3=55∠4=125∠5=55The angle is formed by two rays at a common point of the two rays.
For given figure 1:
∠1+144=180 (Sum of angles on same side of transversal is 180°)
∠1=180-144
∠1=36
∠5+144=180(Sum of angles on a line is 180°)
∠5=180-144
∠5=36
Similarly, ∠3=180-56
∠3=124
∠4+36+56=180(Sum of all angles of a triangle is 180°)
∠4=180-36-56
∠4=88
∠2+36+88=180
∠2=56
Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.
For given, figure 2:
∠1=35(Alternate angle on same side of transversal are equal)
∠2=180-35
∠5=180-35-90(Sum of all angles of a triangle is 180°)
∠5=55
∠4+55=180(Sum of angles on a line is 180°)
∠4=180-55
∠4=125
Similarly, ∠2=180-35(Sum of angles on a line is 180°)
∠2=145
∠3=180-35-90(Sum of all angles of a triangle is 180°)
∠3=55
Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55
