Answer:
13.3 seconds
Step-by-step explanation:
A team of 4 people participates in a 400 -yard relay. And each team member runs the same distance and completed the race in a total of 53.2 seconds.
If we consider that each team member takes equal time for covering his part, then the average running time for each person is
= 13.3 seconds. ( Answer )
1 pound = 16 ounces.
1 can weighs 8 ounces, so 2 cans weigh 8 +8 = 16 ounces, which is 1 pound.
Multiply total pounds by number of cans per pound:
25 pounds x 2 cans per pound = 50 total cans.
Answer:
Step-by-step explanation:
Replace x with -5
2(-5)+7
-10+7
-3
The zeros of a quadratic equation are equal to the x-intercepts of its graph. In other words, you must find the x-value that causes the expression to equal zero. Start by adding 4 to both sides of the equation:
X² - 5x + 4 = 0
Factor the equation:
(x - 1)(x - 4) = 0
Now calculate each piece separately, starting with the first one:
x - 1 = 0
Add 1 to both sides of the equation:
x = 1
We have proven that x = 1. Now calculate the second piece:
x - 4 = 0
Add 4 to both sides of the equation:
x = 4
We have proven that x = 4. Consequently, we have proven that (x = 1) and (x = 4) are the two zeros of this quadratic equation.
I hope this helps!
Answer:
False
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = -
, hence
y = -
x + c ← is the partial equation
to find c substitute (- 3, 5) into the partial equation
5 =
+ c ⇒ c = 
y = -
x +
← equation of line
