Answer: x = 1 and y = 2
Step-by-step explanation:
Solve for y in the first equation by adding 2x to both sides
[tex]y=2x[/tex]
Then plug this in for the y value in the second equation
[tex]3x+4(2x)=11[/tex]
Combine like terms and simplify
[tex]3x+8x=11\\11x=11\\x=1[/tex]
Plug x into either equation to find the y value
[tex]y=2x\\y=2(1)\\y=2[/tex]
y=1x+2 y=3x-4 use substtiution

Bidet used a computer algebra system (CAS) to find the quotient of (4x^3+2x^2+3x+5)^2 and x^2+3x+1. Which statement correctly shows a way to enter this problem into a CAS?
A. Division[4x^3+2x^2+3x+5^2, x^2+3x+1]
B. Division[ (4x^3+2x^2+3x+5)^2] [x^2+3x+1]
C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]
D. Division[2 (4x^3+2x^2+3x+5), x^2+3x+1]
=============================================================
Explanation:
It honestly depends on the CAS program, but for GeoGebra for instance, the general format would be Division[P, Q]
Where,
P = numerator = (4x^3+2x^2+3x+5)^2Q = denominator = x^2+3x+1As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction
We would type in Division[x^2+5x+6, x^3+7]

Determine the domain on which of the following function is increasing
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for [tex]0\leq x\leq 9[/tex].
Since the graph is increasing when [tex]0\leq x\leq 4[/tex], therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
After observing the x-axis points the domain of the function n whose curve is shown in the graph is [0, 9].
The domain of a curve on graph paper refers to the set of all x-values for which the curve is defined or exists.
It's the range of x-values that correspond to points on the curve.
So, the domain can be determined by looking at the x-axis and identifying the range of values that the curve.
In the given graph we can see that,
The curve lies between 0 to 9 on the x-axis.
Thus the fucntion is defined in the interval [0, 9]
Hence,
The domain of the given curve of a fucntion is [0, 9].

If a = 3t - 10 and b = 8-t, which of the following
expresses b in terms of a ?
Answer:
Your answer is. a=14-3b
Hope that this is helpful. Tap the crown button, Like & Follow me
The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equations are given below.
a = 3t - 10 ...1
b = 8 - t ...2
From equation 2, then we have
b = 8 - t
t = 8 - b
Put the value of t in equation 1, then we have
a = 3(8 - b) - 10
a = 24 - 3b - 10
a = 14 - 3b
3b = 14 - a
b = (14 - a) / 3
The equation of 'b' in terms of 'a' will be b = (14 - a) / 3.

Step-by-step explanation:
-3x + 7y = 5x + 2y (you subtract the 2y from both sides)
-3× + 5y = 5x (then add 3x to both sides)
5y = 8x (use x = - 5)
5y = 8x - 5 = -40 (both sides are divided by 5)
y = -8
answer is (-5, -8)
expression equivalent to -3 - 8

Mia can purchase a 40-ounce jar of peanut butter for $5.20 or a 15-ounce jar for $2.70. How much does Mia save per ounce by buying the 40-ounce jar?
Answer:
She pays 0. 05$
Step-by-step explanation:
Cost per once is 40, peanut butter is 5. 20 divide those 2 you will get 0. 13
Now divide it by the butter price 2. 70/15
It will be 0. 18
Subtract 0. 18-0. 15

Solve the system using elimination. 3 x plus 3 y equals 27. x minus 3 y equals negative 11.
Answer:
- 5/4
Step-by-step explanation:
Answer:
x=4 and y=5 commonly notated as (4,5)
Step-by-step explanation:
The equations
Equation 1: 3x+3y=27
Equation 2: x-3y= -11
The second equation looks like it will be the easiest to rearrange.
x-3y = -11
add 3y to each side to get
x = 3y-11
Substitute that in for x in equation 1 so
3x+3y=27
turns into
3(3y-11) +3y =27
multiply out to get
9y-33+3y =27
Condense variables
12y-33=27
add 33 to each side
12y= 60
Divide by 12
y = 5
Plug into one of the original equations (I will be doing both to show it doesn't matter what equation you use, but you only need to use one equation, I personally think it is easier to plug into the second equation)
Equation 1: 3x+3y=27
Plug in what we got for y
3x+3(5)=27
multiply
3x+15=27
subtract 15 from each side
3x=12
divide by 3
x=4
Equation 2: x-3y = -11
Plug in what we got for y
x-3(5) =-11
Multiply
x-15= -11
Add 15 to each side
x=4
