Evaluate the function found in the previous step at X =-3

babunello [35]

$x-5y=-4x-2y$

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

$-3-5y=-4(-3)-2y$

Multiply -4 and -3 in the function above.

$-3-5y=12-2y$

Add 3 on both sides of the equation.

$-3-5y+3=12-2y+3$ $-5y=15-2y$

Add 2y on both sides of the equation.

$-5y+2y=15-2y+2y$ $-3y=15$

Divide both sides of the equation by -3.

$\frac{-3y}{-3}=\frac{15}{-3}$ $y=-5$

Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.

Answer:

f(-3) = -5

AA similarity

Ratios of corresponding sides:

6/8 = 9/12 = 12/16 ⇒ 3/4
SSS similarity

Angle C is vertical

∠ACB ≅ ∠DCE

Ratios of corresponding sides:

Which is a better estimate for the weight of a dresser? 45 grams or 45 kilograms

STatiana [176]

45 grams is about 1/4 cup of water or maybe 1/4 cup of flour or uncooked rice would be 45 grams. Anyway it's not much.

Unless the dresser is made of paper, 45 grams is not enough. 45 kg though large (that's roughly 100 pounds if that's what you think in), the dresser might be found in the apartment where Sherlock Holmes lives. (The dresser is a piece of victorian furniture) it is much closer to what a modern dresser would weigh.
