What is the slope of the line that goes through (2,6) and (4,5)
Answer:
-1/2
Step-by-step explanation:
You find the change in the y coordinates. 6 -> 5 is -1. Now the same for the x. 2 -> 4 is +2. now place them in a fraction with the y/x -1/2. if both were negative then you would just cancel out the negatives.

The measures of two interior angles of a triangle are 108° and 54°. What is the measure of the third angle?
A. 18°
B. 38°
C. 54°
D. 108°
Answer:
Answer is 18 degree as per the question
Answer: A. 18°
Step-by-step explanation:
Your formula is 108°+54°+X=180°
To find X, add 108° & 54°. The sum is 162°.
Next you need to subtract your sum from 180°.
180°-162°=18°
X=18°

Step-by-step explanation:
I just did this on study island :D
For the exponential function as the x-values increase, the function increases towards positive infinity.
What is an exponential function?Exponential function is a function that involves exponents. Exponential function has a constant as its base and a variable as its exponent.
According to the given problem,
f(x) = [tex]3^{x}[/tex]
Let the value of x be -1,
⇒ f(x) = [tex]3^{-1}[/tex]
= 0.33
Now, let the value of x be 1,
⇒ f(x) = [tex]3^{1}[/tex]
= 3
Hence, we can conclude, as the x-values increase, the function increases towards positive infinity.

Step-by-step explanation:
Ramon makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 cups of water with 3 cups of sugar. Whose nectar is more sugary
Answer:
Tiffany
Step-by-step explanation:
Ramon is 4 to 1 water to sugar
Tiffany is 3 to 1 water to sugar
The nectar that is more sugary is Tiffany's nectar.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that Ramon makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Therefore, the ratio of sugar to water can be written as,
Sugar / Water = 2 cups of sugar / 8 cups of water
Sugar / Water = 1/4
Sugar / Water = 0.25 cups of sugar per cup of water
Also, given that Tiffany makes nectar by mixing 9 cups of water with 3 cups of sugar. Therefore, the ratio of sugar to water can be written as,
Sugar / Water = 3 cups of sugar / 9 cups of water
Sugar / Water = 1/3
Sugar / Water = 0.33 cups of sugar per cup of water
Since the ratio of sugar to water is more in Tiffany's nectar (0.33 > 0.25). Therefore, Tiffany's nectar is more sugary.

A beekeeper pours honey into jars. Each large jar holds 18 ounces of honey. Each small jar holds 12 ounces of honey. The beekeeper fills 32 large jars and 46 small jars.
Which answer is the most reasonable estimate of the total amount of honey in the jars?
800 ounces because 10 × 30 + 10 × 50 = 800
1,000 ounces because 20 × 30 + 10 × 40 = 1,000
1,100 ounces because 20 × 30 + 10 × 50 = 1,100
1,600 ounces because 20 × 30 + 20 × 50 = 1,600
Answer:
1,100 ounces because 20 × 30 + 10 × 50 = 1,100

Which value for the constant ccc makes w=5w=5w, equals, 5 an extraneous solution in the following equation? \sqrt{29+4w}=23-cw 29+4w =23−cw
Answer:
c=6
Step-by-step explanation:
In order to solve the original equation, we would have to square both sides of the equation:
\begin{aligned}\sqrt{29+4w}&=23-cw\\\\ \left(\sqrt{29+4w}\right)^2&=(23-cw)^2\\\\ 29+4w&=(23-cw)^2\end{aligned}
29+4w
(
29+4w
)
2
29+4w
=23−cw
=(23−cw)
2
=(23−cw)
2
However, squaring both sides of an equation can create extraneous solutions! [Why?]
Hint #22 / 4
Let's plug \blueD w=\blueD{5}w=5start color #11accd, w, end color #11accd, equals, start color #11accd, 5, end color #11accd into the last equation we obtained:
\begin{aligned}29+4\blueD w&=(23-c\blueD{w})^2\\\\ 29+4(\blueD 5)&=(23-c(\blueD{5}))^2\\\\ 49&=(23-5c)^2\end{aligned}
29+4w
29+4(5)
49
=(23−cw)
2
=(23−c(5))
2
=(23−5c)
2
This equation is correct, both when 23-5c=723−5c=723, minus, 5, c, equals, 7 and when 23-5c=-723−5c=−723, minus, 5, c, equals, minus, 7.
However, the original equation is not correct for 23-5c=-723−5c=−723, minus, 5, c, equals, minus, 7, since this way we obtain \sqrt{49}=-7
49
=−7square root of, 49, end square root, equals, minus, 7.
Hint #33 / 4
Therefore, an extraneous solution is obtained for the ccc-value that makes 23-5c23−5c23, minus, 5, c equal -7−7minus, 7, which is c=6c=6c, equals, 6.
Substituting this back into the original equation gives \sqrt{29+4w}=23-6w
29+4w
=23−6wsquare root of, 29, plus, 4, w, end square root, equals, 23, minus, 6, w. You can now solve this for www and see for yourselves that w=5w=5w, equals, 5 is indeed extraneous.
Hint #44 / 4
The answer is:
c=6c=6
c = 6, makes w = 5 an extraneous solution of the equation √(29 + 4w) = 23 - cw.
What are extraneous solutions?A root of a transformed equation that is not a root of the original equation because it was omitted from the domain of the original equation is referred to as an extraneous solution.
How to solve the question?In the question, we are asked to find the value for the constant c, that makes w = 5, an extraneous solution in the equation:
√(29 + 4w) = 23 - cw.
We first try to solve this equation, by squaring both sides,
29 + 4w = (23 - cw)²,
or, 29 + 4w = 23² - 2(23)(cw) + (cw)²,
or, 29 + 4w = 529 - 46cw + c²w²,
Now, we substitute w = 5, in the above equation to get:
29 + 4(5) = 529 - 46c(5) + c²(5)²,
or, 29 + 20 = 529 - 230c + 25c²,
or, 25c² - 230c + 480 = 0.
Solving this by the quadratic formula, we get:
[tex]c = \frac{-(-230)\pm \sqrt{(-230)^{2}-4(25)(480)}}{2(25)}[/tex] ,
or, [tex]c = \frac{230\pm \sqrt{52900-48000}}{50}[/tex] ,
or, [tex]c = \frac{230\pm \sqrt{4900}}{50}[/tex] ,
or, [tex]c = \frac{230\pm 70}{50}[/tex] ,
or, c = 300/50 or 160/50,
or, c = 6 or c = 3.2.
Now, we will check these values in the original equation by keeping w = 5.
When c = 6:
√(29 + 4w) = 23 - cw,
or, √(29 + 4(5)) = 23 - (6)(5),
or, √(29 + 20) = 23 - 30,
or, √49 = -7,
or, 7 = -7, which is not true.
Hence, c = 6 makes w = 5 an extraneous solution.
When c = 3.2,
√(29 + 4w) = 23 - cw,
or, √(29 + 4(5)) = 23 - (3.2)(5),
or, √(29 + 20) = 23 - 16,
or, √49 = 7,
or, 7 = 7, which is true.
Hence, c = 3.2 makes w = 5 a proper solution.
Therefore, c = 6, makes w = 5 an extraneous solution of the equation √(29 + 4w) = 23 - cw.
