Solve the equation. −2 1/4=r−4/5 will give brainiest for the first correct answer!!!
Answer:
r = -1 9/20
Step-by-step explanation:
-2 1/4 = r - 4/5
Switch sides:
r - 4/5 = -2 1/4
Add 4/5 to both sides.
r = -2 1/4 + 4/5
Change the mixed numeral into a fraction:
r = -9/4 + 4/5
The LCD is 20.
r = -45/20 + 16/20
r = -29/20
r = -1 9/20
Is -12.75 a rational number

Please help solve question 12 and through 14
( will give brianlst :))
Answer:
12. The slope is 2
The y-intercept is 5
13. The slope is 1
The y-intercept is 5
14. The slope is 0.99
The y-intercept is 10
Step-by-step explanation:
12. If you use the rise over run method you go up by 2 and over 1. If you put rise over run you get 2/1 and that is equal to 2. So, slope is 2. The y-intercept is where x=0. If you look you can see that when x is 0, y is equal to 5. Therefore, the y-intercept is 5.
13. The slope is 1 because if you use the slope formula you can use two points like (1,6) and (2,7) in it to find that the slope is 1. You can also see that both the x and y variables go up by 1 each time, so the slope has to be 1. Once again the y-intercept is where x equals 0, even though it isn't shown on the graph we can infer it. At 0 days, the length of the kudzu would be 5 (because 5 is one step less than 6, remember the slope is 1).
14. The slope would have to be 0.99 because each consecutive download is 99 cents. There is a base membership fee of $10 so that has to be the y-intercept.
I hope this helps!!

Evaluate - 2 + (-6) where a = 6.05 and b=3.611.
-a + (-b) where a = 6.05 and b = 3.611
Plug the variables in, then solve the equation
It should look like this:
- (6.05) + (-3.611) = -6.05 - 3.661 = - (6.05 + 3.661)
Add them together then make it negative.
prove that:- (1-sinA)(1+sinA)÷(1+cosA)(1-cosA)=cot^2A
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
[tex]\frac{(1-sinA)(1 + sinA)}{(1+cosA)(1-cosA)}[/tex] ← expand numerator/denominator using FOIL
= [tex]\frac{1-sin^2A}{1-cos^2A}[/tex]
= [tex]\frac{1-(1-cos^2A)}{1-(1-sin^2A)}[/tex]
= [tex]\frac{1-1+cos^2A}{1-1+sin^2A}[/tex]
= [tex]\frac{cos^2A}{sin^2A}[/tex]
= cot²A = right side , thus proven

4. Gilbert works picking strawberries. He
earns $2.50 for each large basket he fills.
a) Draw a scatter plot to represent the
relationship between the number of
baskets Gilbert fills and the money
he earns.
b) If Gilbert's goal is to earn $360.
how many baskets must he fill?
c) Write an algebraic expression to
describe the relationship.
Answer:
Graph is attached
144 baskets
[tex]y=2.5x[/tex]
Step-by-step explanation:
Let y be the total amount of money Gilbert earns and x be the number of baskets filled. So, we get the relation
[tex]y=2.5x[/tex]
Some points which satisfy the equation is
[tex]y=2.5\times 1\\\Rightarrow y=2.5[/tex]
[tex](1,2.5)[/tex]
[tex]y=2.5\times 3\\\Rightarrow y=7.5[/tex]
[tex](3,7.5)[/tex]
[tex]y=2.5\times 5\\\Rightarrow y=12.5[/tex]
[tex](5,12.5)[/tex]
His goal is to earn $360 so [tex]y=360[/tex]
[tex]360=2.5x\\\Rightarrow x=\dfrac{360}{2.5}\\\Rightarrow x=144[/tex]
Hence, to earn $360 he must fill 144 baskets.
The algebraic relation is [tex]y=2.5x[/tex].

Answer:
The temperature farthest from zero is 5
Step-by-step explanation:
the reason for this is because it doesn't matter whether that temperature is negative or positive because all the question is asking is...."how far from zero"....and would -4 be farther from zero....or would 5 be farther from zero. How I know this is absolute value is always positive. And absolute value of -4....is 4.....and absolute value of 5....is 5.
And 5 is 1 temperature more away from zero than -4.
Answer:
5 is the farthest from 0
-4 is the coldest temperature
5 is the warmest temperature
Step-by-step explanation:
The farthest from 0 could be negative or positive. It's just whichever one has the greatest absalute value (if you know that term, if not...), whichever one you would put up more fingers to count to.
In this case, according to the number line, the farthest from 0 into the nagatives is -4, but the farthest from 0 in the positives is 5. This means that 5 is the farthest from 5 because 5 takes 5 of your fingers to count to, whule -4 (yes, even though it's negative) takes just 4 fingers. This is a good way to visualize it until you can wrap your head around it!
The coldest is the lowest number. In this case, it's below zero. Below zero means negatives. In this case, -4 is the lowest number.
The warmest is the highest number. In this case, it's above zero. That means it's a positive number. 5 is the highest number here.

Answer:
f(2) = 9
Step-by-step explanation:
It's give in the question,
Two different functions are,
f(x) = 4x + 1
g(x) = -2x
Then we have to find the output value of function 'f' for the input value x = 2.
By substituting the value of x in the function 'f',
f(2) = 4(2) + 1
= 9
f(2) = 9

What is the sum of the fractions? 3/8 + 1/6
Answer:13/24
Step-by-step explanation:
Answer:
26/48 is the answer
Step-by-step explanation:
Because 3/8 equals 18/48 and 1/6 equals 8/48 so add 18/48 + 8/48 to get 26/48.
Point Q is the image of Q(4-6) under a translation by 1 unit to the right
Answer:
The image of Q(4,-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)
Step-by-step explanation:
Explanation:-
Given image Q( 4, -6)
Type of transformation change to co-ordinate point
a) Horizontal translation left
'C' units (x, y) ⇒ (x- c, y)
b) Horizontal translation right 'C' units (x, y)⇒( x +c ,y )
c) vertical translation up 'd' units (x, y)⇒( x ,y + d )
d) vertical translation down 'd' units (x, y)⇒( x ,y - d )
Now we will use Horizontal translation right 'C' units
image of Q(4-6) under a translation by 1 unit to the right
Q( 4 , -6) ⇒ The new image R( 4+1 ,-6)
The image of Q(4-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)

Suppose that in an election for governor of Oregon there are five candidates of whom two are women. A statistics student reasons as follows: the probability that a woman will win the election is equal to 2/5. What is wrong with this reasoning?
Answer:
If in an Oregon state gubernatorial election, 2 of the 5 candidates are women, and a statistics student establishes that there is a 2/5 chance that the person elected for governor is a woman, this reasoning will be wrong.
This will be the case because not all candidates have the same amount of votes, that is, not all start with the same conditions: thus, there are more popular candidates than others, who will have greater probabilities of being elected as governors, regardless of their sexual identity.
