Answer:
x = -4
Step-by-step explanation:
Since we are given that y = -3, we substitute the y for -3
Now we have:
-3 = 2x + 5
Subtract 5 on both sides to leave 2x alone
-8 = 2x
Divide by 2 on both sides to isolate x
[tex]\frac{-8}{2}[/tex] = x
-4 = x
Answer:
X-4

QUESTION !$ I NEED HELP
Answer:
C
Step-by-step explanation:
What is an equation of the line that passes through the points (-3, -1) and (6, 2)
Answer:
y = 1/3x
Step-by-step explanation:
Using the slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
Taking (-3,-1) as (x1,y1) and (6,2) as (x2,y2):
(2-(-1))/(6-(-3))
= (2+1)/(6+3)
= 3/9
= 1/3
Hence, the slope (m) is 1/3
Substituting the slope into 'y = mx+c':
y = 1/3x + c
Substituting any point, however, we will be substituting (-3,-1):
-1 = 1/3 * (-3) + c
-1 = -1 + c
c = -1 + 1
= 0
Hence,
y = 1/3x

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents
the width of the rectangle in inches, which equation can be used to find its value?
Answer:
Width = 4
Length = 10
Step-by-step explanation:
Width: x
Length: x+6
2x + 2(x+6) = 28
2x + 2x + 12 = 28
4x = 28-12
x = 16/4
x = 4

Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in the simplest form. 180,\, 30,\, 5,\..
Answer:
geometric sequence
Step-by-step explanation:
A geometric sequence has a common ratio r between consecutive terms.
Here r = [tex]\frac{30}{180}[/tex] = [tex]\frac{5}{30}[/tex] = [tex]\frac{1}{6}[/tex]
Then sequence is geometric
The distance that you travel at a constant speed varies directly with the time spent traveling. It takes you 2 h to travel 100 mi. Write an equation for the relationship between time and distance. How far would you travel in 3.5 h?
100 miles is the distance we know traveled in 2 hours. Therefore we can make this equation:
100 = 2x
100 / 2 =x
50 = x
We travel 50 miles an hour.
Now we know the x, 3.5 so lets plug that in:
3.5x = y
3.5(50) = y
175 = y
Therefore we travelled 175 miles in 3.5 hours.
I hope this helps! :)
Answer:
The speed is distance / time and speed times time equals distance
Step-by-step explanation:
speed = 100/2=50 mi/hr
distance =f(t)=50t
f(3.5)=50×3.5=175miles
hope that helps

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
Part B
How many feet apart are the two ocean elevations described in part A?
Part C
What is the elevation of the deck where Winston ate dinner?
Part D
What is the elevation of the surf shop?
Part F
What was the distance between the surf shop and the ocean’s surface at 7 p.m.? Which was higher, the surf shop or the ocean?
