The given expression is

$| 2x-3y | , x=0.5, y=-0.7$

Substituting the given values of x and y, we will get

$| 2(0.5)-3(-0.7) | = | 1+ 2.1 | = |3.1 |$

And absolute value of both positive and negative number is a positive number .

Therefore the final answer is

$| 3.1 | = 3.1$

Janie bought 8 apples and 6 bananas. Each apple costs $0.80, and each banana cost $.60. Answer an expression representing the to

Pavel [41]

A: apples
b: bananas

Your expression could be:

$0.80a + $0.60b = $10.00

----

$0.80 ( 8 ) + $0.60 ( 6 ) = $10.00
$6.40 + 3.60 = $10.00
$10.00 = $10.00

Find the equation of the following ellipse based on the following information: Vertices: (-2,0), (2,0) minor axis of length 2

Sav [38]

Answer:

The expression of the ellipse is: $\frac{x^2}{4} + y^2 = 1$

Step-by-step explanation:

The equation of a ellipse can be written by the following expression:

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:

$2b = 2\\b = 1$

The length of the major axis is the distance between the two vertices.

$2a = \sqrt{[2 - (-2)]^2}\\2a = \sqrt{(2 + 2)^2}\\2a = \sqrt{4^2}\\2a = 4\\a = 2$

Therefore the expression of the ellipse is:

$\frac{x^2}{2^2} + \frac{y^2}{1^2} = 1\\\\\frac{x^2}{4} + y^2 = 1$

why can you write a subtraction problem as an addition problem?How do you write a subtraction problem as an addition problem?

-Dominant- [34]

You can write a subtraction problem as a division problem by subtracting one of the addends from the sum, then your other addend would be the answer.

Example :

5 + 6 = 11

11 - 5 = 6

Find the missing side lengths. leave ur answers as radicals

Mrac [35]

Answer:

x is 2 and y is 2✓3

Step-by-step explanation:

this is because of the 30 60 90 theorem

so 1 is n

and x has to be 2n so it is 2

and y is n√3 so it's 2√3

Romashka-Z-Leto [24]

$\begin{array}{|c|ccccc|} \cline{1-6} x&0&1&2&3&4\\ \cline{1-6} y&2&1&0&-1&-2\\ \cline{1-6} \end{array}$

to get the slope of any straight line, we simply need two points off of it, hmm from the table let's use hmmm (2 , 0) and (4 , -2)

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-2}{2}\implies -1$
