G(-5) = -4*|(-5)-1|

1 answer:

7 0

There is one answer, -24.

While yes, absolute value does indicate both a positive and negative will work, for every x value there will be only one y value associated with it; if there were more, then it would not meet the criteria to be a function.

A store has a sale with 20% off every item. When you enter the store, you receive a coupon that states that you receive an addit

mr_godi [17]

No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.

But if we just took off 30% from 100 originally, you would be at $70.00

So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.

What is vaule of y when x=4'5

Degger [83]

Answer:

$y = 2.096$ or $y = \frac{2\sqrt5+6}{5}}$

Step-by-step explanation:

Given

$y = \frac{4}{x} + \sqrt x + 0.2 - 5x$

$x = \frac{4}{5}$

Required

Find y

$y = \frac{4}{x} + \sqrt x + 0.2 - 5x$

Substitute $x = \frac{4}{5}$

$y = \frac{4}{4/5} + \sqrt{4/5} + 0.2 - 5 * 4/5$

$y = 5 + \sqrt{4/5} + 0.2 - 4$

Collect like terms

$y = \sqrt{4/5} + 5 + 0.2 - 4$

$y = \sqrt{\frac{4}{5}} + 1.2$

Split the surd

$y = \frac{\sqrt4}{\sqrt5}} + 1.2$

$y = \frac{2}{\sqrt5}} + 1.2$

Rationalize

$y = \frac{2\sqrt5}{\sqrt5*\sqrt5}} + 1.2$

$y = \frac{2\sqrt5}{5}} + 1.2$

Take LCM and add

$y = \frac{2\sqrt5+1.2*5}{5}}$

$y = \frac{2\sqrt5+6}{5}}$

or solve as:

$y = \frac{2*2.24+6}{5}}$

$y = \frac{10.48}{5}$

$y = 2.096$

Use two colors of counters to show a way to make 5.color to show the counters . Write the numbers to show the pair that makes 5

Fantom [35]

Answer:

1 and 4, 2 and 3, and 5 and 0.

Step-by-step explanation:

Counters are used by educators to teach children how to do calculations like addition, subtraction, multiplication and division. Using color counters help to visualise the result from the operands in a calculation.

To get the pairs of numbers that adds to 5.

- Use the first color counter to mark out the five ones on the sheet.

- then with the second color counter, subtract one from the five ones.

- repeat the first two steps and increment the subtracted value until it gets to five.

Eliminate the parameter t. Find a rectangular equation for the plane curve defined by the parametric equations.

djverab [1.8K]

Answer:

1. C

2. C

Step-by-step explanation:

1. x = $\sqrt{t}\\$ , y = 4t +3

Solve for t:

t = $x^{2}$

Plug in t:

y = 4( $x^{2}$ ) +3

y = 4 $x^{2}$ +3

2. x = 2t, y = t + 2

Solve for t:

t = x/2

Plug in t:

y = 1/2x + 2
