Which graph represents the function f(x) = |x| - 4

Mathematics

Gwar [14]2 years ago

8 0

Step-by-step explanation:

let's think about it logically :

|x| can only be positive, from 0 to +infinity.

but the second part "- 4" will bring the result for small x values into the negative realm.

x = 0 gives us f(x) = -4.

x = 4 gives us f(x) = 0

x = -4 gives us f(x) = 0

so, if is the 3rd graph (bottom left).

Ross had some stickers. He gave 297 of them to his sister.

Luba_88 [7]

Answer:

Ross has 450 stickers.

Step-by-step explanation:

Ross gave stickers to his sister = 297

If 66% of stickers Ross gave to his sister, how many stickers does Ross have?

Let Ross have stickers = x

So, we can write:

$66\% of x = 297$

Now solving this equation and finding value of x

$66\% of x = 297\\\frac{66}{100}\times x = 297\\x=297 \times \frac{100}{66}\\x=450$

We get x = 450. We know x= Number of stickers Ross has

So, Ross has 450 stickers.

SV is a midsegment of △RTU.<br> If TU=y+38 and SV=y–9, what is the value of y?

pav-90 [236]

Answer:

y = 56

Step-by-step explanation:

the midsegment SV is half the length of the side TU , that is

y - 9 = $\frac{1}{2}$ (y + 38) ← multiply both sides by 2 to clear the fraction

2y - 18 = y + 38 ( subtract y from both sides )

y - 18 = 38 ( add 18 to both sides )

y = 56

x^2 - x/5 + 2 = 0

Subtract 2 from both sides.

x^2 - x/5 = -2

Multiply all terms by 5.

5x^2 - x = -10

Add 10 to both sides.

5x^2 - x + 10 = 0

We can now apply the quadratic formula:

$-b ± \frac{\sqrt{b^2 - 4ac} }{2a}$

1 ± (√ 1 - 200) / 10

1 ± √-199 / 10

1 ± i√199 / 10

<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>
