Help! Which choice is the most efficient first step to solve this set of equations?

Dmitry [639]

Answer:

Substitute 3x - 5 for y in the second equation.

Step-by-step explanation:

Generally, to solve the system of linear equations of x and y, the first step would be trying to eliminate x (or y).

Then turn the system into the equation of only y (or x).

Next, try to solve for y (or x).

Then substitute the solved y (or x) into the original system to work out x (or y).

**********

3 options (1 addition, 2 subtractions) do not eliminate x or y (x and y still exist after manipulation).

=> Remaining option relating substitution would be a reasonable choice.

27. Which expression is NOT equivalent to the other expressions?

Dahasolnce [82]

Answer:

Step-by-step explanation:

Choice A:

$(4x^2y)^2=(4x^2y)(4x^2y)=(4 \cdot 4)(x^2 \cdot x^2)(y \cdot y)=(16)(x^{2+2})(y^{1+1})=16x^{4}y^{2}$

Choice B:

$16x^4y^2$ appears exactly the same as choice A simplified.

Choice C:

$16x^2y^4$ is not the same as A or B since x doesn't have power 4 and y doesn't have power 2.

Choice D:

$4^2x^4y^2=(4 \cdot 4)x^4y^2=16x^4y^2$ is the same as A and B.

So the only odd ball is C.

Slope = rise/run.
slope = change in y/change in x.
slope = (4-2)/(7-4)
slope = 2/3.
