4. Jose is doing his Algebra homework and comes to a problem that
asks him to solve the equation 5x = 2x. He is unsure whether to divide
both sides by 2x or subtract 2x from each side. Will both methods
lead him to a correct solution or is one method correct and the other
incorrect? Explain your reasoning.

Answers

Answer 1

Answer:

x = 0Subtraction method

Step-by-step explanation:

Given equation

5x = 2x

Solving for x

5x - 2x = 2x - 2x3x = 03x/3 = 0/3x = 0

Let's see what the division method gives

5x = 2x5x/2x = 2x/2x2.5 = 1, which is impossible

No solution. This method proves to be incorrect.

The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)

Answers

Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64

Solving Equations

The equations can be solved when you replace the variable x for a given value or find the zero of functions.

The question gives:

                                 r(x)=2x-2

                                 s(x)=-x²

First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,

                                r(x)=2*(-3)-2

                                r(x)=-6-2= -8

Like r(-3)= -8, you should replace x, in s(x), for -8.

                                 s(x)=-(-8)²

                                 s(x)=-64

Hence, s(r(-3)=-64.

Answers

Answer:

Brainliest Answer would be appreciated. Option 1 is the best

Step-by-step explanation:

The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.

Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.

Answer:

B

Step-by-step explanation:

I would use the Pythagorean theorem to solve distances between 2 points, and this case is no exception.

We need to find the positive difference in their x coordinates and y coordinates.

The difference in x coordinates: 7

The difference in y coordinates: 8

Now we can use the Pythagorean theorem:

7^2+8^2 = x^2

49+64 = x^2

113 = x^2

x = sqrt(113)

Therefore, the answer is B.

Answer:

Rs.120

Step-by-step explanation:

given,

Principal (P) = Rs.1200

Time (T) = 2 yrs

Rate (R) = 5%

Simple interest = ?

solution,

simple interest = PTR/100

= Rs.1200*2*5/100

= Rs.12000/100

= Rs.120

Therefore,the simple interest is Rs.120.

Define operation $\heartsuit$ so that \[ a \heartsuit b = \dfrac{a + b}{2}. \] Let $H$ be a function defined by \[H(x,y,z) = \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right). \] Write an expression for a simplified version of this function: $H(x,y,z) = \boxed{\phantom{blaaaaaaaaaa^2_2}}$ Write an expression, not an equation. Sample answer: $x + y + z$

Answers

Answer:

(-x+z)/4

Step-by-step explanation:

Evaluate the $\heartsuit$ operation to simplify.

\begin{align*}

H(x,y,z) &= \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right) \\

&= \left(\dfrac{x+y}{2}\right) \heartsuit z - x \heartsuit \left(\dfrac{y+z} 2\right) \\

&= \dfrac{\dfrac{x+y}{2} + z}{2}  - \dfrac{x + \dfrac{y+z}{2}}{2}

\end{align*}This looks ugly, but it works out! Continue by multiplying each fraction's numerator and denominator by $2$, in order to eliminate the complex fractions.

\begin{align*}

H(x,y,z) &= \dfrac{\dfrac{x+y}{2} + z}{2}  - \dfrac{x + \dfrac{y+z}{2}}{2} \\

&= \dfrac{x + y + 2z}{4} - \dfrac{2x + y + z}{4} \\

&= \dfrac{(x+y+2z) - (2x + y + z)}{4}

&= \dfrac{-x+z}{4}

\end{align*}Surprisingly it simplifies all the way down to $H(x,y,z) = \boxed{\dfrac{-x + z}{4}}$. The value of $y$ is not even used!
