How to solve the Quadratic formul​

Mathematics
1 answer:
Marat540 [252]3 years ago
7 0

Answer:

The answer is x=-6, x=8

Step-by-step explanation:

I recommend using the quadratic formula to solve this problem.

x^2=a

-2x=b

-48=c

Plug it into the quadratic formula.

New equation:\frac{2+-\sqrt{(-2)^2-4(1)(-48)}}{2(1)}

Simplify

Equation: \frac{2+-\sqrt{4+192}}{2}

Add 4 and 192.

Equation: \frac{2+-\sqrt{196}}{2}

Do the square root of 196.

Equation: \frac{2+-14}{2}

Make into two different equations.

Equation 1: \frac{2+14}{2}

Equation 2: \frac{2-14}{2}

Solve the two equations and you will get -6 and 8.  Hope this helps!

Evaluate the following expression:<br> 62 − 7(8 + 6 − 32)
Alex Ar [27]

Answer:

188

Step-by-step explanation:

<u>Step 1:  Distribute</u>

62 − 7(8 + 6 − 32)

62 + (-7 * 8) + (-7 * 6) + (-7 * -32)

62 + (-56) + (-42) + (224)

<u>Step 2:  Combine the first two numbers</u>

(62 - 56) - 42 + 224

6 - 42 + 224

<u>Step 3:  Combine the next two number</u>

(6 - 42) + 224

-36 + 224

<u>Step 4:  Combine the last two number</u>

-36 + 224

In which direction must the graph of Rx) = 7% be shifted to produce the graph of g(x) = 7% + 7?
joja [24]

Answer:

B. Up

Step-by-step explanation:

If you alter a function by adding or subtracting a constant to the end of the expression, then the graph will slide up (down if subtracting) If you alter the x value by altering the expression in close to the x with addition or subtraction the graph will slide left or right.

Vertical translations (sliding up or down) go up when adding and down when subtracting as you would expect it to.

Horizontal translations are the oppoof what you might expect. A (x-h) will shift the graph right, while a (x+k) will shift the graph left.

The answer to your question is UP.
