Answer:
x=40
Step-by-step explanation:
Divide both sides of the equation by 4
0.2x-5=3
Move the constant to the right-hand side and change its sign
0.2x=3+5
Add the numbers
0.2x=8
Divide both sides of the equation by 0.2
x=40
Answer:
The choice that matches the graph of the function as is defined to us is:
Graph A.
Step-by-step explanation:
We are given a function f(x) as:
f(x)= 2x if x < 3
and 4 if x ≥ 3
This means that in the region (-∞,3) the graph of a function is a straight line that passes through the origin and has a open circle at x=3.
and in the region [3,∞) the graph is a straight horizontal line i.e. y=4.
Hence, the graph of this function is:
Graph A.
Answer:
Step-by-step explanation:
perp. -5
y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
Answer:
The total change in his account is of -$85, that is, a loss of $85
Step-by-step explanation:
We combine these changes. So
On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.
On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70
On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85
