Answer:

we have x = -62 or x = 66

Step-by-step explanation:

16=(x-2)^2/3

I would take square root first

4 = (x - 2)^ (1/3)

or -4 = (x - 2)^(1/3)

.....

4^3 = x - 2

64 = x - 2

x = 66

or -4 ^3 = x - 2

-64 = x - 2

x = -62

we have x = -62 or x = 66

Determine whether the cost for ordering multiple items that will be delivered is sometimes, always or never proportional. Explai

Tanzania [10]

It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!

Consider a line passing through the points A(–28, –13) and B(28, 15). Type the y-value for the point C(–24, y) to ensure that po

Nostrana [21]

Step-by-step explanation:

$\frac{y_2-y_1}{x_2-x_1}=\frac{15-(-13)}{28-(-28)}\\=\frac{28}{2(28)}\\\therefore\ m=\frac{1}{2}\\\frac{y-y_1}{xl-x_1}=m]\\\frac{y+13}{x+28}=\frac{1}{2}\\2y+26=x+28\\2y=x+2\\ y=\frac{1}{2}x+1$

In order to find y for point C on AB, substitute point C in line equation if AB.

$y=\frac{1}{2}(-24)+1\\\therefore y=-12+1=11\\\therefore C(-24, -11)$

frutty [35]

Answer:

B. 6 1/4

Step-by-step explanation:

The computation of the more flour Nicholas needed for making the cake and cookies is shown below:

$11 \frac{3}{4} - 5\frac{1}{2}$

= 11.75 - 5.50

= 6.25 more cups of flour

Therefore to make the cookies and cakes, 6.25 more cups of flour is required or needed and the same is to be considered

hence, the correct option is B. 6 1/4

Nicole sold 1 cherry pie and 9 pumpkin pies for $60. Lisa sold 11 cheery pies and 4 pumpkin pies for $90. what's the cost each o

bogdanovich [222]

Cherry pie is $ C.
Pumpkin pie is $ P.

C + 9P =60 -------> C=60 - 9P
11C+4P = 90

11(60 - 9P) +4P=90
660 - 99P + 4P = 90
-95P = -570
P =570/95 = 6
P=6
C=60-9*P=60 - 9*6= 60-54=6
C=6

Answer: 1 cherry pie -$6, 1 pumpkin pie - $6.

Check:
11C+4P = 90 , 11*6 +4*6 =90, 66+24=90, 90=90 True
