Stella solves the following system of equations using the substitution method.
y=−4x−65x−y=10
What is the single-variable equation she solves after substituting?
5x−4x−6=10
5x−(−4x−6)=10
5x+10=−4x−6
5x+10=−(4x−6)
Answer:
5x-(-4x-6) = 10
Step-by-step explanation:
Given the expression
y=−4x−6 ..... 1
5x−y=10... 2
To get the required equation we will substitute equation 1 into 2
5x-y = 10
5x-(-4x-6) = 10
5x+4x+6 = 10
9x+6 = 10
9x = 4
x = 4/9the required equation is 5x-(-4x-6) = 10
Answer:
5x - (-4x - 6) = 6

Dylan walked 1/2 miles in 20 minutes. How far will he go (in miles) in 120 minutes?
Answer:
He will have gone 3 miles after 120 minutes
Step-by-step explanation: 120/20=6 1/2 times 6 is 3.
Answer:
3 miles
Step-by-step explanation:
Divide 20 by 1/2, which would be 40. Then divide 40 by 120, and that would lead to your answer, which is 3 miles.

Solve h = 3xy^2/4 for y
Answer:
[tex]\sqrt{\frac{4h}{3x}}[/tex] = y
Step-by-step explanation:
[tex]h = \frac{3xy^{2}}{4}[/tex]
*4 *4
4h = [tex]3xy^{2}[/tex]
/3 /3
[tex]\frac{4h}{3}[/tex] = [tex]xy^{2}[/tex]
/x /x
[tex]\frac{4h}{3x}[/tex] = [tex]y^{2}[/tex]
[tex]\sqrt{\frac{4h}{3x}}[/tex] = y

Sergio and Allen ate lunch together in the school cafeteria. Each boy ordered a cheeseburger with fries. Sergio only ate 1/7 of his cheeseburger, while Allen ate 3/7 of his cheeseburger. How much cheeseburger did they eat together?
Answer:
4/7
Step-by-step explanation:
The word together symbolizes that we are adding.
We add the numerators but keep the denominator the same since it is already the same.
1+3 is 4, so that is our new numerator.
1 3 4
__ + __ = __

y is directly proportional to x. When y = 24, ,x=8. Work out the value of y when x=2
Answer:
When x = 2, y = 6
Step-by-step explanation:
Constant of Proportionality: y = kx
(24) = k(8)
24 = 8k
k = 3
y = kx ===> y = 3x
When x = 2:
y = 3x
y = 3(2)
y = 6

Consider a function f(x) such that f(5x) =x-5/5x-1. Find f(x) and hence write down the domain of f(x).
Answer:
The domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].
Step-by-step explanation:
Let [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex], which is rearranged by algebraic means:
1) [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex] Given
2) [tex]f(5\cdot x) = \frac{x\cdot 1 - 5}{5\cdot x -1}[/tex] Modulative property
3) [tex]f(5\cdot x) = \frac{5^{-1}\cdot (5\cdot x)-5}{5\cdot x -1}[/tex] Existence of multiplicative inverse/Associative and commutative properties.
4) [tex]f(x) = \frac{5^{-1}\cdot x - 5}{x-1}[/tex] Composition of functions.
5) [tex]f(x) = \frac{(5^{-1}\cdot x-5)\cdot (5\cdot 5^{-1})}{x-1}[/tex] Existence of multiplicative inverse/Associative property.
6) [tex]f(x) = \frac{(x-25)\cdot 5^{-1}}{x-1}[/tex] Commutative, associative and distributive properties/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction
7) [tex]f(x) = (x-25)\cdot [5^{-1}\cdot (x-1)^{-1}][/tex] Definition of division/Associative property
8) [tex]f(x) = (x-25)\cdot (5\cdot x -5)^{-1}[/tex] [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]/Distributive property/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction
9) [tex]f(x) = \frac{x-25}{5\cdot x - 5}[/tex] Definition of division/Result
The domain of a polynomial-based rational function consists in all values of the real set except values where denominator equals zero. The value of [tex]x[/tex] such that rational function becomes undefined is:
1) [tex]5\cdot x - 5 = 0[/tex] Given
2) [tex]5\cdot (x-1) = 0[/tex] Distributive property
3) [tex][5\cdot (x-1)]\cdot 5^{-1} = 0\cdot 5^{-1}[/tex] Compatibility with multiplication
4) [tex](x-1)\cdot (5\cdot 5^{-1}) = 0[/tex] Commutative and associative properties/[tex]a\cdot 0 = 0[/tex]
5) [tex]x-1 = 0[/tex] Existence of multiplicative inverse/Modulative property
6) [tex]x+[1+(-1)] = 1+0[/tex] Compatibility with addition/Commutative and associative properties
7) [tex]x = 1[/tex] Existence of additive inverse/Modulative property/Result
Hence, the domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

A bag contains 10 red, 3 blue, and 2 yellow marbles. If 3 marbles are selected one at a time with replacement, find the probability that all three are different colors
Answer:
4/225
Step-by-step explanation:
To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)
So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.
The probability of getting a red is:
10/15 = 2/3
The probability of getting a blue is:
3/15 = 1/5
The probability of getting a yellow is:
2/15
So to get all 3 different colors:
2/3 * 1/5 * 2/15 = 4/225

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a? + b2 = -2
If a is a rational number and b is a rational number, why could c be an irrational number?
Answer:
For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.
Step-by-step explanation:
We all know, the Pythagorean theorem can be stated as follows:
The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.
i.e.
[tex]a^2+b^2=c^2[/tex]
Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.
Given that:
[tex]a[/tex] and [tex]b[/tex] are rational numbers.
To find:
Situation for which [tex]c[/tex] is irrational.
Square of a rational number is always rational.
So, [tex]a^{2} , b^{2}[/tex] both will be rational.
And sum of squares of two rational numbers will also be rational.
Therefore, [tex]a^2+b^2[/tex] will also be rational.
and
[tex]c = \sqrt{a^2+b^2}[/tex]
For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.
