Linear equation in slope intercept form
Answer:
y = 2x + 24
Step-by-step explanation:
Slope-intercept form equation => y = mx + b
m = slope = change in y / change in x
b = y-intercept
✔️using two pairs of values form the table, (-6, 12) and (-5, 14):
Slope (m) = (14 - 12)/(-5 -(-6))
m = 2/1
m = 2
✔️To find b, substitute (x, y) = (-6, 12) and m = 2 into y = mx + b.
12 = 2(-6) + b
12 = -12 + b
12 + 12 = b
24 = b
b = 24
✔️To write the equation, substitute m = 2 and b = 24 into y = mx + b:
y = 2x + 24

√131 is between 11 and 12? true or false
Answer:
True
Step-by-step explanation:
[tex]11^2=121\\12^2=144\\121<131<144[/tex]
Hence, [tex]\sqrt{131}[/tex] is in between 11 and 12
The mean is 80, the standard deviation is 5. What number is 2.5 standard deviations above the mean? It is a normal distribtion.
Answer:
So the final answers would be (90 > z)-P(80<z) = .47725 or 47.725%

After eight games the team has won two games lost five and tied one if there season is 24 games how many games will they win at this rate
Answer:
Since the games in total add up to 8, we see that 8 is a factor of 24. It goes in 3 times. Therefore, we have to multiply everything by 3 to get the answer out of 24. There will be 6 wins, 15 losses and 3 tie. That adds up to 24.

What two numbers have a product of -22 and a sum of -9?
The probability of choosing a blue marble from a bag is 5/12 and a yellow marble 1/3. What is the probability of not choosing one of these marbles?
Answer:
1/20
Step-by-step explanation:
Simple probability is found by counting all the results which fit requirements and dividing by all possible results.
To find probability of two results in a row, multiply chance of first result by chance of second result.
Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.
There are 5 black marbles
There are 4 red marbles
There are always 20 marbles in all
5/20*4/20=1/4*1/5=1/20
By coincidence, the same as the chance of drawing the white marble in one draw.

1. 28, 48 and 72 are three
number
c) Determine H.C Fof the
three numbers by using
prime factors.
S
#he
Answer:
4.
Step-by-step explanation:
28 = 2*2*7
48 = 2*2*2*2*3
72= 2*2*2*3*3
So the HCF = 2*2 = 4.
Answer:
hcf stand's for
highest common factor

What’s the missing leg?
Answer:
X = 45
Step-by-step explanation:
a^2 + b^2 = c^2
60^2 + a^2 = 75^2
3,600 + a^2 = 5,625
- 3,600 - 3,600
____________________
a^2= 2025
square root them
a^2 = a
2025 = 45
so x =45

The fourth term in an arithmetic sequence is 18 and the seventh term is 39. If the first term is a1 , which is an equation for the nth term of this sequence?
Answer:
aₙ = 7n - 10Step-by-step explanation:
The nth term: [tex]a_n=a_1+d(n-1)[/tex]
So:
a₄ = a₁ + 3d
18 = a₁ + 3d ⇒ 3d = 18 - a₁
a₇ = a₁ + 6d
39 = a₁ + 6d
39 = a₁ + 2(18 - a₁)
39 = a₁ + 36 - 2a₁
39 = 36 - a₁
a₁ = -3
3d = 18 - (-3)
3d = 21
d = 7
So the nth term:
[tex]a_n = -3 + 7(n-1)\\\\a_n=-3 +7n - 7\\\\a_n = 7n - 10[/tex]

Does the following infinite series converge or diverge? 1/3+2/9+4/27+8/81
Answer:
converge
Step-by-step explanation:
The ratio that you multiply by to get the next term is 2/3, which is less than 1, so the geometric series converges by the Geometric Series Test.
Answer:
Converge
Step-by-step explanation:
The value of r in this infinite series is 2/3.
If the absolute value of r is less than 1, then the infinite series converges.
Since 2/3 is less than 1, the series must converge.
