Solve x−9y=19 for y.
Answer:
y = (19 - x) / -9
Step-by-step explanation:
Subtract x from both sides.
-9y = 19 - x
Divide both sides by -9
y = (19 - x) / -9

Answer: (2,-2) (-1,1) (-3,-1) (-2,-4)
Step-by-step explanation:
The x-axis is the horizontal line and the y-axis is the vertical line on a graph. The ordered pairs are always in (x,y).
To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

What is the value of x in 2(5^x) = 14?
A.
0.34
B.
1.15
C.
1.21
D.
219.33
Answer:
C
Step-by-step explanation:
Using the rule of logarithms
ln[tex]x^{n}[/tex] ⇔ nlnx
Given
2([tex]5^{x}[/tex] ) = 14 ( divide both sides by 2 )
[tex]5^{x}[/tex] = 7 ( take ln of both sides )
xln5 = ln7 ( divide both sides by ln5 )
x = [tex]\frac{ln7}{ln5}[/tex] ≈ 1.21 ( to 2 dec. places ) → C
Answer:
Step-by-step explanation:
here is your solution
First you divide the sides by 2
2(5^x)/2=14/2
5x=7
apply exponent rules
log(5x)=log(7)

Step-by-step explanation:
two candles, each initial length of 30cm, are 20cm apart. the thinner candle burns at a rate of 1cm every 8 minutes and the other candle burn at a rate of 1 cm every 10 minutes. find two possible lengths for the distance between the tops of the two candles, if the candles can burn up for 3 hours.
Thinner candle:
y = length of the candle
x = rate it burns at every minute
y = -1/8x + 30
Thicker candle:
y = length of the candle
x = rate it burns at every minute
y = -1/10x + 30
To find the length after 3 hours:
y = -1/8(180) + 30
y = -1/10(180) + 30

Factor Completely.
25z^2 − 36w^2
Answer:
(5z-6w)(5z+6w)
Step-by-step explanation:
Hi there!
We're given the expression 25z²-36w² and we want to factor it.
The expression written as a difference of squares. The difference of squares is given as a²-b²=(a-b)(a+b)
Let's label the values of what is a² and b², and then try to determine what a and b are from that information
[tex]a^{2}=25z^2\\b^2=36w^2[/tex]
Alright then! Let's square root both sides to find what a and b are
[tex]\sqrt{a^2}=\sqrt{25z^2[/tex]
Which then means:
a=5z
And then for b:
[tex]\sqrt{b^2}=\sqrt{36w^2}[/tex]
b=6w
Now substitute those values into the formula
a²-b² = (a-b)(a+b)
[tex]25z^{2}-36w^2=(5z-6w)(5z+6w)[/tex]
Hope this helps!

Write an equation for the following real life scenario.
Use "t" to represent your variable.
Jasmine's cell phone company charges her $35 a month for phone service plus 0.50 for each text message. Her
total bill for the month was $51.
Answer:
[tex]35+0.50t=51[/tex]
Step-by-step explanation:
Since the $35 is a one-time fee, 0.50 is the rate, t is the variable, and 51 is the total bill, we can form the equation:
[tex]35+0.50t=51[/tex]
Answer:
0.50t+35=51
Step-by-step explanation:
0.50 is the amount for each text message so it becomes 0.50t (0.50 × text message). This is added to the monthly cost which is 35 dollars (+35) the question wants an equation as the answer so (=51).

The chart below shows the coordinates for the vertices of Quadrilateral DEFG. Quadrilateral DEFG undergoes a translation of 2 units to the right, resulting in Quadrilateral D'E'F'G'. What are the coordinates of the vertices for new quadrilateral?
The movement of a point along the coordinate geometry is referred to as translation. The coordinates of the vertices for new quadrilateral are:
[tex]D' = (3,2)[/tex]
[tex]E' = (8,3)[/tex]
[tex]F' = (4,5)[/tex]
[tex]G' = (10,6)[/tex]
Given that:
[tex]D = (1,2)[/tex]
[tex]E =(6,3)[/tex]
[tex]F = (2,5)[/tex]
[tex]G = (8,6)[/tex]
The rule of transformation for 2 units right translation is:
[tex](x,y) \to(x + 2, y)[/tex]
So, we have:
[tex]D' = (1+2,2)[/tex]
[tex]D' = (3,2)[/tex]
Using the above formula, the other coordinates are:
[tex]E' = (8,3)[/tex]
[tex]F' = (4,5)[/tex]
[tex]G' = (10,6)[/tex]
Hence, the coordinates of the vertices for new quadrilateral are:
[tex]D' = (3,2)[/tex]
[tex]E' = (8,3)[/tex]
[tex]F' = (4,5)[/tex]
[tex]G' = (10,6)[/tex]

Graph x+4y=8
what is the x-intercept?
Answer:
(4,1)
Step-by-step explanation:
Answer:
x=8 or (8,0)
Step-by-step explanation:
The x-intercept of a function is the value of which y=0, or the coordinate points where the function crosses through the x-axis.
Observing the attached graph, you can see that the line crosses the x-axis at the point (8,0). This means that x=8 when y=0, which holds true algebraically since x+4y=8 -> 8+4(0)=8 -> 8+0=8 -> 8=8.
Therefore, the x-intercept of the function is x=8 or (8,0).
The square of the difference between 2x and y
Answer:
this question doesn`t have much information but here`s my best guess
(2x-y)^2
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y.
1. **Difference between 2x and y:** The difference between 2x and y is calculated by subtracting y from 2x. This gives us the expression "2x - y," which represents the numerical difference between these two quantities.
2. **Square of the Difference:** To square this difference, we simply multiply "2x - y" by itself. When you square something, you multiply it by itself. In mathematical notation, squaring is denoted using an exponent of 2, which is written as "^2."
So, combining the two steps, we have:
[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y. When you expand this expression, you get a quadratic expression, which may include terms like [tex]4x^2, y^2[/tex], and -2xy, among others, depending on the values of x and y.
