If you're asking how, here's an example
A standard form equation is when it is set up.
Ax + By = C.
6x + 2y = 4.
A slope-intercept form equation is when it is set up y=mx+b.
Y = - 3x + 2.
4y = -8x + 16 then divide all by 4.
y = -2x + 4 slope form.
Answer:
2.275%
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where
x is the raw score = 70 mph
μ is the population mean = 100 mph
σ is the population standard deviation = 15 mph
z score = 70 - 100/15
z score = -30/15
z score = - 2
Determining the Probability value from Z-Table:
P(x ≤ 70) = P(x < 70)
= P(z = -2)
= 0.02275
Hence the probability of the player's serve that are less than 70 mph is 0.02275
Converting it to percentage
= 0.02275 × 100
= 2.275%
Therefore, the percentage of the player's serve speeds that are less than 70 mph is = 2.275%

Answer: B {x:x<=9
Step-by-step explanation:
The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail
Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20
60 + 20 = 80
20 x 3 = 60
Mikhail is 20 years old.
