Given the expression-1/2(4x-6) +2 (x2-5x+5) complete the instructions below

Art [367]

Answer:

A) 2x^2 -12x +13

B) terms {2x^2, -12x, 13}; coefficients {2, -12, 13}; constants {13}

Step-by-step explanation:

A) Using the distributive property, we get ...

-2x +3 +2x^2 -10x +10

= 2x^2 -12x +13

B) Terms: {2x^2, -12x, 13}

Factors: There are no overall factors. Each term has factors ...

2x^2 has factors {2, x, x}

-12x has factors {-1, 2, 2, 3, x}

13 has factors {1, 13} (it is prime)

Coefficients: {2, -12, 13} . . . see note below

Constants: {13}

_____

<em>Additional comment</em>

We have listed the prime factors of each term, any subset can be multiplied to be a factor of the term. For example, 2·3 = 6 is a factor of -12x.

Please note that some sources do not consider a constant (13) to be a coefficient. You will need to refer to your curriculum materials to see what your author says about that.

Rewrite each fraction with a denominator of 24 2/3 and 5/8

Tresset [83]

Answer:

2/3 = 16/24

5/8 = 15/24

Step-by-step explanation:

2/3= 16/24

5/8= 15/24

because if you multiply across $\frac{2}{3}$ by $\frac{8}{8}$ equal $\frac{16}{24}$

and if you multiply across $\frac{5}{8}$ by $\frac{3}{3}$ equal $\frac{14}{24}$

Does the point (0,4) make either equations y=-2x and y=x+3 true? Explain.

Nikolay [14]

Answer:

Neither

Step-by-step explanation:

To verify, we substitute the values in the equations:

$y = -2x\\y = -2 \times 0\\y = 0$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

$y = x+3\\y= 0+3\\y = 3$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.
