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!

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).

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).

Answer:

6n/8 = m

Step-by-step explanation:

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:

(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).

Answer: i think that a is inverse and b is contrapositive. If i am wrong, sorry. I haven't even learned about contrapositive yet so-

Answer:37930000

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The easiest way to find the answer is to convert all of the fractions to have the same denominator,...

A = (22/55 / 11 = 2/5 and 2/5 * 20)            = 40/100

B = (17/20 * 5)                                             = 85/100

C = (4/5 * 20)                                              = 80/100

D = (3/4 * 25)                                              = 75/100

B (Lily) is the highest followed by C (Nikki), D (Sydney), and A (Monica)

Hope it helps,... Chow,...!

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)

Answer is c

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

Answer:

-8

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.

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]
