Use elimination to solve the system of equations given by 3x - 2y = 10 and 5x + 2y = 6
Answer:
x = -2 y= -8 and 8
Step-by-step explanation:
Since there is an equal number of y's, they cancel out when subtracting. You can put either equation on top. You will get same answer.
To find x:
If you do (3x - 2y = 10) - (5x + 2y = 6), you will get -2x=4. Divide both sides by -2, and get x = -2.
If you do (5x + 2y = 6) - (3x - 2y = 10), you will get 2x=-4.Divide both sides by 2, and get x = -2.
To find y:
Substitute -2 for x in either equation. It doesn't matter.
For 3(-2) - 2y = 10:
3(-2) - 2y = 10 ––Multiply
-6 - 2y =10 ––Add 6 to both sides to get y alone
-2y = 16 ––Divide by -2
y = -8
For 5x + 2y = 6:
5(-2) + 2y = 6 ––Multiply
-10 + 2y = 6 ––Add 10 to both sides to get y alone
2y = 16 ––Divide by 2
y = 8

Calculate the sum of cubes. If the input is x, the sum of cubes is equal to: 13 + 23 + ... + x3 Take input for the number of cubes to sum. No error checking is needed. Specifically, you may assume that the input is always a positive integer Here are some sample runs: Enter how many cubes to sum: 1 1 Enter how many cubes to sum: 3 36 Enter how many cubes to sum: 4 100 Enter how many cubes to sum: 2 9
Answer:
In Python:
cubes = int(input("Enter how many cubes to sum: "))
sum = 0
for i in range(cubes+1):
sum = sum + i**3
print(sum)
Step-by-step explanation:
This line prompts the user for the number of cubes
cubes = int(input("Enter how many cubes to sum: "))
This initializes sum to 0
sum = 0
This iterates through the inputted number
for i in range(cubes+1):
This calculates the sum of the cube of the numbers
sum = sum + i**3
This prints the calculated sum
print(sum)

Bill purchases a bond for $1,200. It pays 7% simple annual interest and matures in 8 years. How much interest will Bill earn
after the bond reaches maturity?
Answer:
672
Step-by-step explanation:
I'm going to assume that this is a zero-coupon bond
simple interest is as follows
PV(1+it)
we have
1200(1+.07*8)
1200*1.56=1872
This is the accumulated value
to find the interest earned we use the following equation
AV-PV
we have
1872-1200=672

What is the y-intercept of y = –2x+6?
Answer:
thw y intercept iz 6 and the z
slope is -2x
Step-by-step explanation:
hope this helps
Answer: y = 6
Step-by-step explanation:
1. Let y = 0 to find the x-intercept(s).
0=-2 x +6
2. Subtract 6 from both sides.
- 6 = - 2 x
3. Divide both sides by -2.
-6/-2 = x
4. Two negatives make a positive so 6/2 = x
5. Simplify 6/2 to 3.
3 = x
6. Switch sides.
x = 3
2. y-Intercept
1. Let x = 0 to find the y-intercept(s).
y = -2 x 0+6
2. Simplify and get y = 6
(4,7) up 3 units and right 6 units
Answer:
(4,7) up 3 units and right 6 units is (10,10)
Step-by-step explanation:
(4,7) goes up 3 units, which becomes (4,10). (Go up: 7 + 3 = 10)
(4,10) moves to the right 6 units, which becomes (10,10). (Right: 4 + 6 = 10)
Suppose a poker hand contains seven cards rather than five. Compute the probabilities of the following poker hands: (a) a seven-card straight (b) four cards of one rank and three of a different rank (c) three cards of one rank and two cards of each of two different ranks (d) two cards of each of three different ranks, and a card of a fourth rank (e) three cards of one rank and four cards of each of four different ranks (f) seven cards each of different rank
Answer:
a) 0.00031
b) 0.0017
c) 0.31
d) 0.00018
Step-by-step explanation:
attached below is the detailed solution
Total number of 7-poker cards are 52P7 = 133784560
A) Determine the probabilities of Seven-card straight
probability of seven-card straight = 0.00031
B) Determine the probability of four cards of one rank and three of a different rank
P( four cards of one rank and three of different rank ) = 0.0017
C) Determine probability of three cards of one rank and two cards of each two different ranks
P( three cards one rank and two cards of two different ranks ) = 0.31
D) Determine probability of two cards of each of three different ranks and a card of a fourth rank
P ( two cards of each of three different ranks and a card of fourth rank ) = 0.00018

Triangle with sides of 10, 7 and x
x² = 10² + 7²x² = 149x = √149x = 12.2-------------------
Triangle with sides 3, 16 and 17
