Is (-1,2) a solution to the following linear equation:
2x + y = 2

Answers

Answer 1
Plug in the values
2(-1) + 2 = 2
-2 + 2 = 2
0 = 2, false

(-1,2) is not a solution
Answer 2

Answer:

No

Step-by-step explanation:

plug in the variables into the equation

(x,y)

(-1,2)

2(-1)+2=2

2*-1=-2

-2+2=0

2 does not equal 0 so therefore no, it is not a solution

For Items 16-28, determine whether each function is
even, odd, or neither.
f(x) = -x + 2x + 5
f(x) = x + 8x
f(x) = -7x² + 5
f(x) = 5x + 3x? – 7x + 1

Answers

Answer:

f(x) = -x + 2x + 5

is odd since f(x) = -5

f(x) = x + 8x

is neither because f(x) = 0

f(x) = -7x² + 5

is odd since f(x) = √5/7

f(x) = 5x + 3x? – 7x + 1

is odd

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?

Answers

Answer:

the single decimal multiplier is 1.0058

Step-by-step explanation:

Let us have 100

Decreasing by 6% will be

100 - 0.06(100)

= 94

Increasing by 7%

= 94 + 0.07(94)

= 100.58

So

to get the single decimal multiplier,

we have 100.58/100 = 1.0058

A ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

The quantitative and relatable relation between two amounts of goods or numbers shows the number of times one value contains or is contained within the other or one number/value with respect to the other number/value.

It is basically the relationship between two similar magnitudes with respect to the number of times the first contains the second.

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The first incorrect step occurred in Step 1, where all the exponents were increased by 4.

This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.

For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.

We multiply the exponents instead of adding them together.

Therefore, the correct Step 1 should multiply all the variables' exponents by 4.

Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.

Step-by-step explanation:

4x + y = 6 => 8x + 2y = 12.

8x + 2y = 12

+ (-5x - 2y = -3)

=> 3x = 9, x = 3.

Therefore 4(3) + y = 6, 12 + y = 6, y = -6.

The solutions are x = 3 and y = -6.

Define x: Let x be the number of hours

Derrick Dogs sitting:

Fixed charged=$12

Hourly change=$5

Total charge=12+5x

Darlene dog sitting:

Fixed charged=$18

Hourly change=$3

Total charge= 18+3x

Find the total number of hours so that both cost are the same:

12 + 5x = 18 + 3x
