Consider this system:
3x + 1/2y = 3
6x - y = 2
Which of the following operations would eliminate the y-terms if the two equations were added together afterward?
A. Multiply the first equation by -2.
B. Multiply the first equation by 2.
C. Multiply the second equation by -2.
D. Multiply the second equation by 2.
Answer:
B. Multiply the first equation by 2
hope this helps tell me if you need more :)
Multiply the first equation by 2 then the variable y will be eliminated. Then the correct option is B.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Consider this system:
3x + 1/2y = 3 ...1
6x - y = 2 ...2
The operations would eliminate the y-terms if the two equations were added together afterward will be
Multiply the first equation by 2. Then we have
6x + y = 6
6x - y = 2
Add the above equations, then we have
12x = 8
y is eliminated.

how do you solve
x-3y=-5
x+3y=1
Answer:
I got you fam
Step-by-step explanation:
First One:
x -3y = -5
x = -5 + 3y
Or
x -3y = -5
-3y = -5 -x
y = 5/3 + x/3
Second one:
x +3y = 1
x = 1 - 3y
Or
x + 3y = 1
3y = 1 -x
y = 1/3 - x/3

The least-squares regression equation
y = 120 + 40x can be used to predict the cost of renting a backhoe for x hours. Suppose it costs $325 to rent a backhoe for 5 hours.
Calculate the residual for renting the backhoe for 5 hours, to the nearest hour.
The residual is _____
Answer:
5
Step-by-step explanation:
just did on edge
The residuals is $5
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given, The least-squares regression equation
y = 120 + 40x
This equation can be used to predict the cost of renting a backhoe for x hours
If it costs $325 to rent a backhoe for 5 hours.
We need to Calculate the residual for renting the backhoe for 5 hours,
Plug 5 in place of x in equation
y=120+40(5)
y=120+200
y=320
Since the The observed value is $325.
To find residual for renting the backhoe for 5 hours
We have to separate 320 from 325
325-320=5
Hence the residual is 5.

Number 2.
A homeowner is wanting to pave his
drive way. He was quoted for every 240
bricks it would cost $30. Find the unit
rate.
(a) (4,4) is a point on a locus whose equation is y2 = kx. Show that (16,8) is another point on the locus.
(b) (2,3) is a point on a locus whose equation is 5x +by= 16. Show that (0,8) is another point of the locus
Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
Answer:
Please check the explanation.
Step-by-step explanation:
a)
Given
(4,4) is a point on a locus whose equation is y²=kx
Putting (4, 4) in y²=kx
(4)² = k(4)
16 = 4k
k = 16/4
k = 4
Checking the point (16, 8) on the locus
y²=kx
Putting (16, 8) and k =4 in y²=kx
y²=kx
(4)² = 4×4
16 = 16
L.H.S = R.H.S
Therefore, (16, 8) is another point on the locus.
b)
Given
(2, 3) is a point on a locus whose equation is 5x +by= 16
Putting (2, 3) in 5x +by= 16
5x+by=16
5(2)+b(3)=16
10+3b=16
3b=6
b=6/3
b=2
Putting (0, 8) and b=2 in 5x +by= 16
5x +by= 16
5(0)+2(8)=16
0+16=16
16=16
L.H.S = R.H.S
Therefore, (0, 8) is another point on the locus.

Dena has 6.25 inches of blue ribbon, 0.375 foot of orange ribbon, and 0.5 yard of green ribbon. How many inches of ribbon does Dena have altogether?
Show or explain your work through either decimal or fractional calculation.
Answer:
28.75inStep-by-step explanation:
We are expected to convert all units to inches in this problem
Step one:
given data
blue ribbon=6.25 inches
orange ribbon=0.375 foot
green ribbon=0.5 yard
Step one:
convert orange ribbon=0.375 foot to inches
1 ft = 12 in
0.375ft=xin
cross multiply
x=12*0.375
x=4.5in
orange ribbon= 4.5in
convert green ribbon yd to inches
1 yd = 36 in
0.5 yd=xin
cross multiply
x=36*0.5
x=18in
green ribbon= 36in
total lenght in inches =6.25+4.5+18
=28.75in
