9514 1404 393

Answer:

  (a)  = 7 +3·5

Step-by-step explanation:

The given expression evaluates to ...

  6 +2^4 = 6 +16 = 22

The offered choices evaluate to ...

  7 +3·5 = 7 +15 = 22

  4·10^3 +96 = 4·1000 +96 = 4096

  7^2 = 49

  3·10 +2 = 30 +2 = 32

The only choice that will form a proper equation is the expression that evaluates to 22:

  6 +2^4 = 7 +3·5

Ymorist [56]

Answer:

no

Step-by-step explanation:

Given

1 + 4(3x - 10) - 12x ← distribute the parenthesis

= 1 + 12x - 40 - 12x ← collect like terms

= 1 - 40

= - 39 ≠ - 9

What is the distance between A and B? Round your answer to the nearest tenth.
poizon [28]
\bf ~~~~~~~~~~~~\textit{distance between 2 points}&#10;\\\\&#10;A(\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})\qquad &#10;B(\stackrel{x_2}{4}~,~\stackrel{y_2}{1})\qquad \qquad &#10;%  distance value&#10;d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}&#10;\\\\\\&#10;AB=\sqrt{[4-(-1)]^2+[1-5]^2}\implies AB=\sqrt{(4+1)^2+(1-5)^2}&#10;\\\\\\&#10;AB=\sqrt{5^2+(-4)^2}\implies AB=\sqrt{41}

Which of the following best describes similar figures that are not congruent?
Drupady [299]

Answer:

A

Step-by-step explanation:

Being similar means that the shapes will have the same shape and dilation factor between sides, but if they are not congruent then the size will not be the same.

If f(x) = x-9, then f '(x) =​
erica [24]

Answer:

1

Step-by-step explanation:

If you are just looking for the derivative, then all you need to use the power rule for this. Technically the x in (x-9) has a power to the 1, so really x^1-9. To use power rule, you bring down the exponent, in this case, 1, and then minus 1 from what the exponent was.

1x^(1-1) = 1x^0. The derivative of any constant is 0, so don't even worry about the -9. We know that anything raised to the zero is just 1, so in this case your answer is 1.

Hope this helps :)
