xenn [34]4 years ago
3 0

Answer:

Picture #1: True

Picture #2:

12y - 6 - 4y = 14

8y - 6 = 14

8y = 20

y = 20/8= 5/2

Picture #3

-3y-10=5y+14

-8y - 10 = 14

-8y = 24

y = -3

Picture #4

.50x. + 4.50 = 31.50

.50x = 27.00

x = 54

Picture #5

15x - 24 = 15x - 24

answer is b

PLEASE HELP!! The San Francisco Bay tides vary between 1 foot and 7 feet. The tide is at its lowest point when time (t) is 0 and
nadezda [96]

Answer:

C. Amplitude = 3 feet; period = 8 hours; midline: y = 4

Step-by-step explanation:

The midline is halfway between the lowest point and the highest point.

y = (1 + 7) / 2

y = 4

The period is the time it takes for a full cycle.  So the period is 8 hours.

The amplitude is the distance from the midline to the lowest or highest point.

a = 4 − 1 = 3, or a = 7 − 4 = 3

It's also half the distance between the lowest and highest points.

a = (7 − 1) / 2

a = 3

A line passes through (-5, -3) and is parallel to -3x - 7y= 10. The equation of the line in slope-intercept form is
adell [148]

Answer:

A.

Step-by-step explanation:

-3x-7y = 10

In slope - intercept form

y = -3/7x - 10/7

Since the lines are parallel so the slopes will be equal

m = -3/7

Now

Point = (x,y) = (-5,-3)

So, x = -5, y = -3

Putting in slope intercept form to find b

y = mx+b

-3 = (-3/7)(-5) + b

-3 = 15/7 + b

7b = -21-15

7b = -36

b = -36/7

Now the slope intercept form for the line is

y = -3/7x-36/7
