Match the following items by evaluating the expression for x = -7. x-2 x-1 x0 x1 x2

frosja888 [35]

Answer:

${x}^{ - 2} = \frac{1}{ {x}^{2} } \: \: –> {7}^{ - 2} = \frac{1}{ {7}^{2} } = \frac{ 1}{49} \\ \\ {x}^{ - 1} = \frac{1}{ {x}^{1} } \: –> {7}^{ - 1} = \frac{1}{ {7}^{1} } = \frac{1}{7} \\ \\ {x}^{0} –> {7}^{0} = 1 \\ \\ {x}^{1} –> {7}^{1} = 7 \\ \\ {x}^{2} –> {7}^{2} = 49$

Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom

Troyanec [42]

For this case we propose a system of equations:

x: Variable that represents the amount of hours that Olivia's mother drove

y: Variable that represents the amount of hours that Olivia's father drove

So, we have:

$x + y = 14\\65x + 60y = 895$

From the first equation we have:

$x = 14-y$

Substituting in the second equation:

$65 (14-y) + 60y = 895\\910-65y + 60y = 895\\-5y = 895-910\\-5y = -15\\y = \frac {15} {5}\\y = 3$

Thus, Olivia's father drove 3 hours.

$x = 14-3 = 11$

Olivia's mother drove 11 hours.

Answer:

$(x, y) :( 11,3)$
