Write an equation of the line that passes through (−2,3) and (0,8).
Answer:
[tex]y = \frac{5}{2}x + 8[/tex]
Step-by-step explanation:
(-2 , 3 ) ; (0 , 8)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{8-3}{0-[-2]}\\\\=\frac{5}{0+2}\\\\=\frac{5}{2}[/tex]
m = 5/2 ; (0 , 8)
Equation: y -y1 = m(x -x1)
[tex]y - 8 =\frac{5}{2}(x - 0)\\\\y - 8 =\frac{5}{2}x\\y = \frac{5}{2}x + 8[/tex]

0 = 0 (Infinitely many solutions)
5(a + 4) - 15 = -5(a - 1)
5a + 20 - 15 = -5a + 5
5a + 5a = 5 - 20 + 15
10a = 40
10a/10 = 40
a = 4

Answer:
1 = 7x=42 (divide both sides by 7)
7x/7 =42/7
x=6
2.=9y=81 (divide both sides by 9)
9y/9y= 81/9
y=9
3.= –40=8a (divide both sides by 8)
–40/8= 8a/8
a=5
4.=y divided 11=12
y=11 multiplied by 12
y= 132
5.= –15y=135( divide both sides by –15)
–15y/–15=135/–15
y= –9
6.= 17p=51(divide both sides by 17)
17p/17=51/17
p=3
7.= –65= –13w (divide both sides by 13)
–65/–13=–13w/–13
w=5
8.=y/–2=4
(cross multiply)
y/–2=4/1
4 multiplied by –2= –8
therefore:y= –8

Answer:
a) 7x=42
Step-by-step explanation
use the co-efficient of the unknown to divide both sides
7x=42
7x/7=42/7
x=6
9y=81
9y/9=81/9
y=9
-40=8a
is the same thing as

-8a/-8=40/-8
a=-5
y+11=12
y=12-11
y=1
-15y=135
-15y/-15=135/-15
y=9
17p=51
17p/17=51/17
p=3
-65=-13w
13w=65
13w/13=65/13
w=5
y/-2= 4
cross multiply y=-8

Out of 498 applicants for a job, 187 have over 10 years of experience and 127 have over 10 years of experience and have a graduate degree. Step 1 of 2 : What is the probability that a randomly chosen applicant has a graduate degree, given that they have over 10 years of experience
Answer:
the probability that randomly selected applicants over 10 years of experience is 0.6791
Step-by-step explanation:
The computation of the probability that randomly selected applicants over 10 years of experience is as follows:
Total would be
= 187 have 10 + years experience
Now
P(graduate | 10+) = (graduate and 10+ years experience) ÷ (10 + years of experience)
= 127 ÷ 187
= 0.6791
Hence, the probability that randomly selected applicants over 10 years of experience is 0.6791

Step-by-step explanation:
Passes through (-4,-5) Slope = -314
Please Helppppp!!!!!!!!!!!!
Answer:
[tex]y=-314x-1261[/tex]
Step-by-step explanation:
When we are writing an equation we have to put it in slope-intercept-form [tex]y=mx+b[/tex]. We already know the slope it's -314, we replace m with the slope. Now we have to find b which is the y-intercept. So what we have to do is plug in the ordered pair into the equation. -4 for x and -5 for y.
[tex]y=mx+b\\-5=-314(-4)+b[/tex]
Now we solve
[tex]-5=-314(-4)+b\\-5= 1256+b\\b=-1261[/tex]
So now that we know everything we need we plug in and....
[tex]y=mx+b\\y=-314x-1261[/tex]
we've got our equation!
Answer:
The line slants upward, so the slope is positive.

The top of a 25-foot ladder is sliding down a wall at a rate of 3 feet per second. When the top of the ladder is 15 feet from the ground, what is the rate of change between the bottom of the ladder and the wall?
Answer:
1.8ft/s
Step-by-step explanation:
Using the formula for calculating Speed as shown:
Speed = Distance/Time
Time = Distance/Speed
t = d/s
Given
d1 = 25 foot
s1 = 3ft/s
d2 = 15ft
Required
s2
Using the formula;
d1/s1 = d2/s2
s2 = s1d2/d1
s2 = 3*15/25
s2 = 45/25
s2 = 1.8ft/s
Hence the rate of change between the bottom of the ladder and the wall is 1.8ft/s
