Answer:
-4 and 6
Step-by-step explanation:
sum means +
-4+6=2
difference means -4-6=10
Answer:
'-18' is the constant in the expression -18 - 3a.
Step-by-step explanation:
We know that in an algebraic expression the constant term has a fixed value and it can not be changed.
For example,
The expression x + 2 contains two terms, x and 2. Here, '2' is a constant term because it has a fixed value and cannot be changed.
IN OUR CASE,
Given the expression
-18 - 3a
As '-18' is a fixed number and its value can not be changed.
Therefore, '-18' is the constant in the expression -18 - 3a.
Answer:
25≥ w
i dont have the inquality sign
Step-by-step explanation:
multiply both sides by 5/4
We need to find m and b to find in the equation of a line:
y = mx + b
↑ <span>↑
slope y-intercept
To find m, the slope, we need to find the rise over the run of the line. You pick two points and use the y values finding the difference of them and do the same for the x values and put them on the bottom. Let's use the points (0, -2) and (4, 0):
</span>↑ ↑<span>
(x₁, y₁) (x₂, y₂)
m = (y</span>₂ - y₁)/(x₂ - x₁)
m = (-2 - 0)/(0 - 4)
m = (-2)/(-4)
m = 1/2
The slope is positive since the line is going upward from left to right.
Now we need b, the y intercept, where the line intersects with the y axis, simply by looking at the graph. b is -2.
Thus, the answer is C. y = 1/2x - 2.
Answer:
The Jesse swim fastest
Step-by-step explanation:
Given as :
The distance cover by Elizabeth while swimming = 50 feet
The time taken by Elizabeth = 10 sec
So, Speed of Elizabeth = 
∴ Speed of Elizabeth = 
= 5 feet per sec
Again ,
The distance cover by Jesse while swimming = 110 feet
The time taken by Jesse = 20 sec
So, Speed of Jesse =
∴ Speed of Jesse = 
= 5.5 feet per sec
Again ,
The distance cover by Reagan while swimming = 160 feet
The time taken by Reagan = 30 sec
So, Speed of Reagan =
∴ Speed of Reagan = 
= 5.3 feet per sec
So, 
Hence The Jesse swim fastest Answer
