Answer:
1 Answer: Since these two lines are the same line, they have infinite solutions Answer: So first thing you gotta do is multiply the first equation by 5. Your first equation will be. Since these two lines are the same line, they have infinite solutions.
Another Answer: You would have to multiply either equation in order to get one of the variables to cancel.
I would multiply the first equation by -5.
-5(3x + 6y = -2)
-15x -30y = 10
15x + 30y = -10
0 + 0 = 0
Since everything cancels and the equation is true, the solution is Infinitely many solutions, or all real numbers.

What is the domain and the range to this
Answer:
Look Down below :P
Step-by-step explanation:
If you were looking for if it even has a domain and range let's say if the point (15/4,7) should have read (15/4,17) then a plot of these points appears to show a hyperbola and the x and y (f(x)) axes look like Asymptotes. If the general function has the form f(x)=a/x, then there should be a consistent value for a which can be found be substituting the points in the equation. Take one point (17,15/4) and we get 15/4=a/17, from which a=255/4. f(x)=255 x/4. We have no negative values as examples so we cannot assume that the function is defined for negative values of x. f(x)=255 x/4 fits all the points except for (15/4,7), which is possibly mis-typed. The domain of the function is therefore all values of x>0 and the range of f(x) is f(x)>0, assuming continuity and extrapolation of the function.
If the point (15/4,7) is valid then f(x) as defined above is invalid or incomplete. f(x) may be a piece wise function where f(x)=7 if and only if x=15/4. For 0<x<15/4 and x>15/4, f(x)=255 x/4. These would be the domain for x. The range of f(x) is f(x)>0 and f(x)=7 only when x=15/4.
3) (2.01) Identify the domain and range. Then, determine whether the
relation is a function or not. Explain your reasoning.
Relation: (-1,0) (2, 4) (0, 3) (2, 1) (6,5)

Answer:
the x- coordinate of the turning point is - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
y = x² + bx + c with y- intercept = (0, - 14 ) then c = - 14 , so
y = x² + bx - 14
To find b substitute (2, 0 ) into the equation
0 = 2² + 2b - 14
0 = 4 + 2b - 14
0 = - 10 + 2b ( add 10 to both sides )
10 = 2b ( divide both sides by 2 )
5 = b , then
y = x² + 5x - 14
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the turning point is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 5x - 14 ← is in standard form
with a = 1 and b = 5 , then
x- coordinate of turning point = - [tex]\frac{5}{2}[/tex]
Write an equation of the line (4,3) and (9,-2)
Answer:
y= -x + 7
Step-by-step explanation:
to get the equation of a line is y=mx+b
the slope, m, would be calculated (y1-y2)/(x1-x2)
thus we would substitute in (3--2)/(4-9)
which simplifies to 5/-5
or -1
now we know that m= -1
to solve for b we have to put the equation into point-slope form which is
y-y1= m(x-x1)
this would be y-3 = -(x-4)
y-3 = -x+4
y= -x+7
Rewrite the quadratic equation in standard form 4x^2=2x-6
Answer:
Answer Below....
Step-by-step explanation:
Answer:
4x^2 - 2x + 6
Step-by-step explanation:
The "standard form" of the quadratic equation is ax^2 + bx + c.
Here we have 4x^2 = 2x - 6, whose terms must be rearranged to resemble ax^2 + bx + c. Term 4x^2 stays where it is, but + 2x - 6 on the right side must be moved to the left side, which results in: 4x^2 - 2x + 6

Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles how many red marbles does it contain
If a bag has 30 orange marbles then that means it has 42 red marbles
Step-by-step explanation:
If there are 7 red marbles for every 5 orange marbles then what you would do is.
30/5=6
6*7=42
Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles Then the bag contains 42 red marbles.
In the problem, we are given that each bag of marbles contains 7 red marbles for every 5 orange marbles. We need to find the number of red marbles when there are 30 orange marbles in the bag.
Let's represent the number of red marbles as R and the number of orange marbles as O.
According to the information provided, we have the following relationship:
R / O = 7 / 5
Now, we are given that the number of orange marbles (O) in the bag is 30. We can substitute this value into the equation:
R / 30 = 7 / 5
To find the number of red marbles (R), we can cross-multiple
R = (7 / 5) * 30
R = 42
Therefore, the bag contains 42 red marbles.
In summary, we used the given ratio of red to orange marbles in the bag to set up a proportion and then solved for the number of red marbles when the number of orange marbles was known. This allowed us to find that there are 42 red marbles in the bag.

Answer:
3√5
Step-by-step explanation:
Square root of 45
Square Root of 45: √45 = 6.708
We can find the square root of 45 using the following steps:
Step 1: Check whether the number is a perfect square or not. In this case, 45 is not a perfect square as it cannot be broken down into a product of two same numbers.
Step 2: Once the number is checked, the following process needs to be followed:
If the number is a perfect square, it can be written in this format √x2 = x
If it is not a perfect square, the square root is found using the long division method. It can also be written in its simplified radical form.
Since 45 is not a perfect square, we find its square root using the long division method. The simplified radical form of the square root of 45 is given below.
Simplified radical form of the square root of 45-
45 can be written as a product 9 and 5. Hence, square root of 45 can be expressed as, √45 = √(9 × 5) = 3√5. 45 is not a perfect square, hence, it remains within roots. The simplified radical form of the square root of 45 is 3√5.

this is a pretty easy problem cuz all u need to do is find which one of the options has a product of 729.
option a) 7 * 8 * 12
well 7 * 8 * 12 equals 672, so that cannot be the box
option b) 8*9*11
8*9*11 = 792. cant be the box cuz 792 does not equal 729
option c) 9*9*9
9*9*9=729
option c is the box cuz 729 = 729

you must use substitution method
x+y=7
2x+y=10
Answer:
x = 3, y = 4
Step-by-step explanation:
First, set the first equation equal to x. Note the equal sign, what you do to one side, you do to the other.
Subtract y from both sides of the equation:
x + y = 7
x + y (-y) = 7 (-y)
x = 7 - y
Next, plug in 7 - y for x in the second equation:
2x + y = 10
2(7 - y) + y = 10
Simplify. First, distribute 2 to all terms within the parenthesis:
2(7 - y) = (2 * 7) + (2 * -y) = 14 - 2y
Next, combine like terms. Like terms are terms with the same amount of the same variables:
14 - 2y + y = 10
14 (-2y + y) = 10
14 - y = 10
Isolate the variable, y. First, subtract 14 from both sides of the equation:
-y + 14 (-14) = 10 (-14)
-y = 10 - 14
-y = -4
Next, isolate the variable, y, by dividing -1 from both sides of the equation:
(-y)/-1 = (-4)/-1
y = -4/-1 = 4
Next, plug in 4 for y in one fo the given equations:
x + y = 7
x + (4) = 7
Isolate the variable, x. Subtract 4 from both sides of the equation:
x + 4 (-4) = 7 (-4)
x = 7 - 4
x = 3
x = 3, y = 4

What is the image of the point (-5, -9) after a rotation of 90° counterclockwise
about the origin?
Answer:
(9, -5)
Step-by-step explanation:
If you rotate a figure 90 degrees counterclockwise, the coordinates will go from (x, y) to (-y, x).
So, let's start out with -y. The y-value of (-5, -9) is -9, and the negative value of that is -(-9) or 9. That goes first in our point: (9, x.) Now, we just keep our x-value the way it is, -5, and put that in our y-value: (9, -5). And there's our point after a 90 degree counterclockwise rotation.
