Answer:Shift Up and Down by Changing the Value of k

You can represent a vertical (up, down) shift of the graph of f(x)=x2 f ( x ) = x 2 by adding or subtracting a constant, k . If k>0 , the graph shifts upward, whereas if k<0 , the graph shifts downward.

PLEASE HELP ASAP!!! WILL MARK BRAINLIEST!!!!

crimeas [40]

Answer:

Part 1) $-\sqrt{15}$

Part 2) $x=\frac{b+ac}{2c-ab}$

Step-by-step explanation:

Part 1) we know that

To put factor back into the square root, we have to put squared value

we have

$-5\sqrt{0.6}$

Remember that

$5=\sqrt{5^2}$

substitute in the expression above

$-5\sqrt{0.6}=-\sqrt{(5^2)(0.6)}=-\sqrt{25*0.6}=-\sqrt{15}$

Part 2) we have

$\frac{2x-a}{b}=\frac{ax+1}{c}$

Solve for x

That means----> Isolate the variable x

Multiply in cross

$(2x-a)c=(ax+1)b$

Apply distributive property

$2cx-ac=abx+b$

Group terms

$2cx-abx=b+ac$

Factor x left side

$x(2c-ab)=b+ac$

Divide by (2c-ab) both sides

$x=\frac{b+ac}{2c-ab}$

1/4+1/10 Add or subtract. Write the answer in simplest form.

vagabundo [1.1K]

Answer:

7/20

Step-by-step explanation:

To add fractions, the first step is to get a common denominator

1/4 + 1/10

The common denominator is 20

1/4 *5/5 = 5/20

1/10 *2/2 = 2/20

5/20 + 2/20 = 7/20
