IN WORDS EXPLAIN THE PROCESS TO SOLVE THIS SYSTEM OF LINEAR EQUATIONS BY ELIMINATION.
2x + 4y = 20
-6X - 4y = 24
Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24
-24 -24
-6x = 12
x= -2
Answer:
(2,3)

For every 6 inches of height, Lashacha has an arm span of about 6.17 inches. If Lashacha is 6 ft 5 in. tall, predict the width of her arm span.
Answer: 79.18 inch.
Step-by-step explanation:
Given: For every 6 inches of height, Lashacha has an arm span of about 6.17 inches.
i.e. for each inch of height she has an arm span of = [tex]\dfrac{6.17}{6}[/tex] inches
Height of Lashacha = 6 ft 5 in.
1 ft = 12 inches
Then, Height of Lashacha = [6(12)+ 5] = 77 in.
So for 77 inch height she has arm span of [tex]\dfrac{6.17}{6}\times77=79.18\text{ inch}[/tex]
Hence, the width of her arm span = 79.18 inch.

Write a power that has a value greater than 340 and less than 345
The power that has a greater value than 340 and less than 345 is 343 which is 7³.
What is prime factorisation ?Prime factorisation of numbers is writing a given number in terms of prime divisors.
For example -: 36 = 6 × 6.But 6 is not a prime number.
∴ 36 = 6 × 6 = 2×3×2×3 = 2² × 3².
To obtain the power of a number which is greater than 340 and less than 345 we have prime factorise these given numbers and see which one them is a perfect square or a perfect cube.
If we prime factorise 343 which is = 7 × 7 × 7.
So, 7³ = 343.

three workers produce 1500 cans in 4 days. how many days can four workers produce 4000 cans?
a)11
b)10
c)9
d)8
1500 cans / 3 workers = 500 cans per worker.
1 worker makes 500 cans in 4 days.
4 workers x 500 cans = 2000 cans in 4 days.
2000 x 2 = 4000 cans, 4 days x 2 = 8 days.
It will take 8 days.

The product of two rational numbers is a rational number.
What is a rational number?"A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator 'p' and a non-zero denominator 'q'."
Therefore, when we are multiplying two rational numbers, their product must be a rational number.
This is because, numerators of both rational numbers are integers and denominators of both the numbers are non-zero integers.
Hence, the product is a rational number.

The volume of the prism is
m3.
Answer:
V = 4576 m^3
Step-by-step explanation:
length l = 26 m
width w = 22 m
height h = 8 m
diagonal d = 34.9857114 m
total surface area S_tot = 1912 m^2
lateral surface area Sl_at = 768 m^2
top surface area S_top = 572 m^2
bottom surface area S_bot = 572 m^2
volume V = 4576 m^3
Agenda: l = length
w = width
h = height
d = diagonal
S_tot = total surface area
S_lat = lateral surface area
S_top = top surface area
S_bot = bottom surface area
V = volume

solve for the x in the equation
[tex]x + 3x + 5x + 7x + ...49x = 625[/tex]
Answer:
x=1
Step-by-step explanation:
x+3x+5x+7x+...+49x=625
(1+3+5+7+...+49)x=625 (1)
now consider s= 1+3+5+7+...+49
a=1
d=3-1=2
l=49
l=a+(n-1)d
49=1+(n-1)2
49-1=(n-1)2
48/2=n-1
n-1=24
n=24+1=25
s=n/2*(a+l)
s=25/2(1+49)
x=25/2×50
s=25×25=625
from (1)
625 x=625

If g(x) = {(4, -5), (-3, 2), (-6, 1), (1,0)}, which set of ordered pairs represents
the inverse of g(x)?
O A. {(-5, 4), (2, -3), (1, -6), (0, 1)}
O B. {(-4,5), (3, -2), (6, -1), (-1,0)}
O C. {(5, -4), (-2,3), (-1,6), (0, -1)}
O D. {(4, -5), (-3,2), (-6, 1), (1, 0)}
Answer:
The inverse of g(x) is {(-5, 4), (2, -3), (1, -6), (0, 1)} ⇒ (A)
Step-by-step explanation:
To find the inverse of a function switch x and y
Example:
If f(x) = {(1, 2), (-4, 5), (0, 0)}
To find its inverse switch x and y in each ordered pair
The inverse of f(x) = {(2, 1), (5, -4), (0, 0)}
Let us do the same with our question
∵ g(x) = {(4, -5), (-3, 2), (-6, 1), (1, 0)}
→ Switch x and y coordinates in all ordered pair
∴ The inverse of g(x) = {(-5, 4), (2, -3), (1, -6), (0, 1)}
Look at the answer to find the correct choice
It is (A)
Answer:
A. {(-5, 4), (2, -3), (1, -6), (0, 1)}
Step-by-step explanation:
You are flipping the x and y values.
