deff fn [24]

Answer:

False solution; [1⅐, -3 3⁄7]

Step-by-step explanation:

{x - 2y = 8

{4x - y = 8

-¼[4x - y = 8]

{x - 2y = 8

{-x + ¼y = -2 >> New Equation

____________

-1¾y = 6

y = -3 3⁄7 [Plug this back into both equations to get the x-coordinate of 1⅐]; 1⅐ = x

The following problem describes procedures that are to be applied to numbers. Repeat the procedure for four numbers of your choi

mart [117]

Answer:

Conjecture: For every number x, the result of the is 2x

Step-by-step explanation:

First Number: 8

Multiply by 88: $88 * 8 = 704$

Add 88: $704 + 88 = 792$

Divide by 44: $792/44 = 18$

Subtract 2: $18 - 2 = 16$

Second: 10

Multiply by 88: $88 * 10 = 880$

Add 88: $880+88=968$

Divide by 44: $968/44=22$

Subtract 2: $22-2=20$

Third: 5

Multiply by 88: $88*5 = 440$

Add 88: $440+88=528$

Divide by 44: $528/44=12$

Subtract 2: $12-2=10$

Fourth: 2

Multiply by 88: $88*2=176$

Add 88: $176+88=264$

Divide by 44: $264/44=6$

Subtract 2: $6-2=4$

On a general terms:

Let the number be x.

Multiply by 88: $88x$

Add 88: $88x + 88$

Divide by 44: $\frac{88x + 88}{44} = \frac{88x}{44} + \frac{88}{44} = 2x+2$

Subtract 2: $2x + 2 - 2 = 2x$

Notice that for every input x, the result is 2x

Your choice of answer D is correct.

_____

When the number of days is zero, the height is 130 inches. This eliminates choices B and C. Evaluating the expression for n=13 gives

... 130 + 13×13 = 130 + 169 = 299 . . . . . corresponding to answer D.

Find the value of y so that the line passing through the two points have the given slope (2,3) (7,y) m=-2/5

Liono4ka [1.6K]

Answer:

y = 1

Step-by-step explanation:

Find the slope of the line passing through the points $(2,3)$ and $(7,y):$

$m=\dfrac{y-3}{7-2}=\dfrac{y-3}{5}$

The slope of the line is equal to

$m=-\dfrac{2}{5},$

then

$\dfrac{y-3}{5}=-\dfrac{2}{5}\\ \\y-3=-2\\ \\y=-2+3\\ \\y=1$
