Answer:
x = -11
Step-by-step explanation:
To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.
-11 + 4 = -7
(-7)^2 = 49
Answer:
x = -11
Step-by-step explanation:
To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.
Joanne a total score for a round of darts was -42 she had thrown 6 darts and scored the same each throw How many points did Joanne score on each throw
Answer:
7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Ok, so we know 42 is the number of points added up, and we know that she threw 6 darts all scoring the same. Now, all we have to do is figure out what number(for example x) multiplied by 6 equals 42. Or in the form of an equation:
6x = 42
Now, to finish the equation, all we have to do is divide:
6x/6 = 42/6
42/6 = 7
x = 7

Find the slope of the line through points (4, 6) and (-6,2).
Answer: Slope = 2/5
Concept:
Here, we need to know how to find the slope.
Slope = (y₂ - y₁) / (x₂ - x₁)
If you are still confused, please refer to the attachment below for a clearer version of the formula
Solve:
Given information
(x₁, y₁) = (-6, 2)
(x₂, y₂) = (4, 6)
Given formula
Slope = (y₂ - y₁) / (x₂ - x₁)
Substitute values into the formula
Slope = (6 - 2) / (4 - (-6))
Simplify values in the parentheses
REMEMBER to change [+, -] signs when there is a [-] sign in front
Slope = 4 / (4 + 6)
Slope = 4 / 10
Divide both numerator and denominator by 2 to get the simplest form
Slope = (4 ÷ 2) / (10 ÷ 2)
Slope = 2/5
Hope this helps!! :)

Answer:
x=4, y=3.
Step-by-step explanation:
Solving for x,
⟿ 3x-1=11
⟿ 3x=11+1
⟿ 3x=12
⟿ x=12/3
⟿ x=4.
Solving for y,
⟿ 5y=15
⟿ y=15/5

PLEASE HELP COMPARING RATIOS
Answer:
John: 8 Hong: 5 Keith: 7
Step-by-step explanation:
Divided each larger number by three smaller one, and that is how much time each flyer spent.
( a+b) ^2-a^2+b^2
kkkkkkkkkkkkkkk
Answer:
It is assumed the question is asking to simplify or factorize:
(a + b)² - a² + b² = a² + 2ab + b² - a² + b² = 2b² + 2abThis is simplified expression.
Factorizing as follows:
2b² + 2ab = 2b(a + b)Step-by-step explanation:
[tex](a + b) {}^{2} - {a}^{2} + b {}^{2} [/tex]
a² + 2ab + b² - a² + b²
Cancelling a²
2ab + b² + b²
2ab + 2b²
Taking 2 and b as common
2b(a + b)
To take a taxi it costs $3.00 plus an additional $2.00 per mile traveled.You Spent exactly $20 on a taxi which includes the $1 tip you left.
How many miles did you travel?
=======================================================
Work Shown:
x = number of miles
2x = cost of traveling x miles, at $2 per mile, without including the $3 fee
2x+3 = total cost now including the $3 entrance fee, without tip
2x+3+1 = total cost plus $1 tip
2x+4 = amount you spent
2x+4 = 20
2x = 20-4
2x = 16
x = 16/2
x = 8
You traveled 8 miles.
Hey there! I'm happy to help!
Let's represent the number of miles traveled with the variable m.
We see that it will cost $2 for every mile, so for if we drive 8 miles, it will cost $16, 9 will be $18, and so forth. So the relationship is that the cost will be double the money, so what we have here is 2×m. In algebra, you can simply write variable multiplication as just putting the numbers next to each other, so 2m will be that part of the equation.
We see that the initial cost of the taxi is $3.
3
We are going to be adding our $2 per mile to this amount (2m).
3+2m
And we will add our $1 tip.
3+2m+1
And this is equal to $20.
3+2m+1=20
We can combine the 3 and the 1 to give us 4.
4+2m=20
So, we see that 2m+4 is equal to 20. If we subtract that four from 20, we will see that 2m is equal to 16.
We remember that our cost from mileage is double the miles, so if 16 is double something, we just divide by two!
16/2=8
So, this means that we traveled 8 miles!

8/15 divided by -0.35 as fraction
Hi, I'm happy to help!
To solve this problem, we can turn -0.35 into an equivalent fraction.
[tex]\frac{8}{15}[/tex]÷[tex]\frac{-0.35}{1}[/tex]
For division, I like to use the strategy called KFC. This stand for Keep, flip, and change. You keep the first fraction, flip the second, and change the operation.
[tex]\frac{8}{15}[/tex]×[tex]\frac{1}{-0.35}[/tex]
Now we multiply the top by the top and the bottom by the bottom.
[tex]\frac{8}{-5.25}[/tex]
We know that the negative applies to the entire fraction, so we write it like this:
-[tex]\frac{8}{5.25}[/tex]
