{5x−2y=43x−4y=−6 What is the answer

Mathematics
1 answer:
Reil [10]2 years ago
5 0

Answer:

(2,3)

Step-by-step explanation:

5x - 2y = 4           (1)

3x - 4y = -4          (2)

Multiply equation 1 by 2

10x - 4y = 8                Subtract 2 from the equation on this line

<u>3x   -4y = - 6</u>

7x = 14                       Divide by 7

x = 14/7

x = 2

5x - 2y = 4

5*2 - 2y = 4

10 - 2y = 4

-2y = 4-10

-2y = - 6

y = -6/-2

y = 3

I may not have read this correctly. Please put those 2 equations on separate lines.

If f(x) = 2х2 +1 and g(x) = х2 -7, find (f-g)(x).
Nookie1986 [14]

Option A

If  f(x) = 2x^2 + 1 and g(x) = x^2 - 7 then (f - g)(x) = x^2 + 8

<em><u>Solution:</u></em>

Given that f(x) = 2x^2 + 1 and g(x) = x^2 - 7

To find: (f - g)(x)

We know that,

(f – g)(x) = f (x) - g(x)

Let us substitute the given values of f(x) and g(x) in above formula,

(f - g)(x) = 2x^2 + 1 - (x^2 - 7)

For solving the brackets in above expression,

There are two simple rules to remember:

When you multiply a negative number by a positive number then the product is always negative.

When you multiply two negative numbers or two positive numbers then the product is always positive.

So the expression becomes,

(f - g)(x) = 2x^2 + 1 -x^2 + 7

Combining the like terms,

(f - g)(x) = 2x^2 - x^2 + 1 + 7\\\\(f - g)(x) = x^2 + 8

Thus option A is correct
