Find the value of Q in the following system so that the solution to the system
is {(x,y) : x – 3y = 4} x - 3y=4
2x + Qy=8
Answer:
Q = -6Step-by-step explanation:
If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.
x - 3y = 4 multiply both sides by 2
2x - 6y = 8
Therefore Q = -6
If A • B*2 = 1.8 x 10*-7, and C•B/D = 7.2 x 10*-4, find the value of A•D*2/C*2
Answer:
-7.2
Step-by-step explanation:
The value of expression A•D²/C² is 1.8 x 10⁻⁷ / D².
To find the value of A•D²/C², we can first rearrange the given equations and then manipulate them to get the desired expression.
Given equations:
A • B² = 1.8 x 10⁻⁷
C • B/D = 7.2 x 10⁻⁴
Let's manipulate the second equation to get C by itself:
C • B/D = 7.2 x 10⁻⁴
C = (7.2 x 10⁻⁴) • (D/B)
Now, substitute the expression for C from the second equation into the first equation:
A • B² = 1.8 x 10⁻⁷
A = (1.8 x 10⁻⁷) / B²
Now, we have expressions for both A and C:
A = (1.8 x 10⁻⁷) / B²
C = (7.2 x 10⁻⁴) • (D/B)
Now, let's find the value of A•D²/C²:
A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B/D)²
Since (B/D)² = B²/D²:
A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B²/D²)
Now, B² in the numerator and denominator cancel out:
A•D²/C² = 1.8 x 10⁻⁷ / D²
Thus, the value of A•D²/C² is 1.8 x 10⁻⁷ / D².

Which point on the x-axis lies on the line that passes
through point C and is parallel to lino AB?
Answer:
(2,0)
Step-by-step explanation:
For given line AB:
y-intercept = b = -2
slope = m = y₂-y₁/x₂-x₁
= -3/2-(-4) = -3/6 = -1/2
Equation of line AB:
y = (-1/2)x - 2
Finding equation of line that is parallel to line AB and passes through the point C(2,2):
Substituting the slope from line AB into the equation of the line
y = (-1/2)x + b.
Substituting the given point (-2,2) into the x and y values 2 = (-1/2)-2 + b.
Solving for b (the y-intercept) , we get b = 1
Substitute this value for 'b' in the slope intercept form equation y = (-1/2)x + 1.
For x-intercept of the line, we let y = 0
0 = (-1/2)x + 1
x = -1(-2/1)
x = +2
So, the point on the x-axis that lies on the line that passes
through point C and is parallel to line AB is (2,0).

The parent function f(x)=x3 and a translation, g(x), are shown on the graph. Which represents g(x), then the translated function?
ANSWER
The correct answer is A
EXPLANATION
The parent function is
[tex]f(x) = {x}^{3} [/tex]
The function g(x) is obtained by shifting the graph of the parent function, 4 units left and 6 units up.
Therefore the transformation is of the form:
[tex]g(x) = f(x + 4) + 6[/tex]
Hence the transformed function has equation:
[tex]g(x) = {(x + 4)}^{3} + 6[/tex]
The correct answer is A
The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6
Translation of functionsTranslation is a way of changing the position of an object on an xy plane. According to the graph shown, the parent function of the graph is f(x) = x^3.
The translates function shows an upward translation by 4 units and horizontal translation to the left by 6 units. The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6

A line intersects the point (3,-4)and has a slope of 17 .what is the slope - intercept equation for this line?
Answer:
The slope - intercept equation for this line is y = 17x - 55
Step-by-step explanation:
The general form of the slope-intercept form is
y = mx +b
where m is the slope and b is the y-intercept.
We are given slope m = 17
we need to find b the y-intercept.
To find y-intercept we would use point(3,-4) and formula
y = -4
x = 3
m = 17
b=?
y = mx + b
-4 = (17)(3) + b
-4 = 51 + b
b = -4 -51
b = -55
So, y-intercept is -55
The slope - intercept equation for this line is y = 17x - 55
Find the coordinates of the point where y-4x=1 crosses the y axis
Answer:
(0, 1)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 4x = 1 ( add 4x to both sides )
y = 4x + 1 ← in slope- intercept form
with y- intercept c = 1 ⇒ (0, 1) ← coordinates of y- intercept
The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)
The following information should be considered:
The equation of a line in slope - intercept form is y = mx + c Here m is the slope and c the y- intercept.Now y - 4x = 1.So here we have to add 4x to the both sides. So, y = 4x + 1.Now the coordinates is (0,1)
Therefore we can conclude that The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)

PLS HELP QUICK IM TIMED!!!!
Answer:
Say that the price at the whole for a bottle is some x
We know that the Snack Bar sold them at 33% profit which is in dollars $0.28
i.e 33% x=0.28
so now its a matter of finding what x is
writing this in algebraic form
0.33x=0.28
divide both sides of the equation by 0.33
0.33x/0.33=0.28/0.33
Therefore x=0.85 roughly
so the price per bottle at the whole sell is 85 cent

Assume that a population of newly discovered small creatures called “porgs” in a remote island lays eggs with three distinct appearances: patterned with dots, white, or dark grey. Last year, the porgs laid 30 dotted eggs, 40 grey eggs, and 15 white eggs. You randomly selected 25 eggs, 10 of which were dotted, 13 were grey and 2 were white. Based on this information, what is the probability that you would only collect 2 white eggs?
you have a 1/12.5 chance of getting a white egg. so the theoretical possibility of getting only two white eggs is 1/156.25. so it is very unlikely to get two white eggs
Answer:
0.029
Step-by-step explanation:
Last year, the porgs laid 30 dotted eggs, 40 grey eggs, and 15 white eggs.
Total eggs = 30+40+15 = 85 eggs
White eggs = 15
So, probability of getting 1 white egg = [tex]\frac{\text{No. of white eggs}}{\text{Total no. of eggs}}[/tex]
= [tex]\frac{15}{85}[/tex]
Remaining white eggs = 14
Total eggs remaining = 84
Probability of getting 1 white egg on second draw = [tex]\frac{14}{84}[/tex]
So, the probability that you would only collect 2 white eggs =[tex]\frac{15}{85} \times \frac{14}{84}[/tex]
=0.029
Hence the probability that you would only collect 2 white eggs is 0.029.
When 60% of a number is added to the number, the result is 192
Answer:
the number (x) is 120.
Explanation:
100% + 60% = 160% = 1.6
(just multiply it by 1.6 because it is equal to 60%)
The equation for the problem can be expressed as x + 0.6x = 192. To solve for x, you simplify the equation and isolate x, resulting in the answer of 120.
Explanation:This problem is a simple algebraic problem in which we're trying to find a number that satisfies a given condition. To solve this, we need to express the problem as an equation. Let's assume the number we're looking for is denoted as x. So, according to the problem, we have the following equation:
x + 0.60x = 192
The steps to solve this equation are as follows:
Combine like terms: 1x + 0.60x = 1.60xTo isolate x, divide both sides of the equation by 1.60: x = 192 / 1.60Doing the division on the right side, we find x = 120, which is our number.

Answer:
3^x-8=8 then x=log_3(16)
3^(x-8)=8 then log_3(8)+8
Step-by-step explanation:
So if it is 3^x-8=8
then 3^x=16
and then convert to logarithmic form you write it as log_3(16)=x
_3 means the subscript (the base) is 3
So if it is 3^(x-8)=8
then the log form is log_3(8)=x-8
add 8 on both sides log_3(8)+8=x

Answer:
5
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/ (x2-x1)
= (-3-3)/(4-1)
=-6/3
= -2
Then we can use point slope form to make the equation
y-y1 = m(x-x1)
y-3 = -2(x-1)
Distribute
y-3 = -2x+2
Add 3 to each side
y-3+3 = -2x+2+3
y = -2x+5
Since this is in slope intercept form, y = mx +b, the y intercept is 5
Answer: D. 5
Step-by-step explanation: First we need to find the slope
m = (y2-y1)/ (x2-x1)
= (-3-3)/(4-1)
=-6/3
= -2
Then we can use point slope form to make the equation
y-y1 = m(x-x1)
y-3 = -2(x-1)
Distribute
y-3 = -2x+2
Add 3 to each side
y-3+3 = -2x+2+3
y = -2x+5
Since this is in slope intercept form, y = mx +b, the y intercept is 5
