Answer:
Step-by-step explanation:
we know that
The general equation of a quadratic function in factored form is equal to
where
a is a coefficient of the leading term
x_1 and x_2 are the roots
we have
substitute
Applying the distributive property convert to expanded form
therefore
Answer:
-33 or 33
Step-by-step explanation:
The seventh term of an AP is written as:
The eleventh term of an AP is written as:
If the 7th term is 11 times the 11th term, then;
Expand to get:
We must have a=-52 and d=5
Or
a=52 and d=-5
For the first case, the 18th term is :
For the second case,
2 1/5x * 1 7/10 y * 4 3/5 x 1 7/10 (* 7 4/50)
Finds the answer
10 6/50x * 7 41/50y (* 7/4/50) = 56
79 13/100 (* 7 4/50) = 56
560 = 56 (10x)
x = 5 6/10
7 (y) = 56 (7y)
8 = 56/7 (y)
y = 8
x = 5 6/10
6/10 of 560 = 336
336/60 = x
336/60 = 5 6/10
Answer:
In one hour Stephanie earns $1.50 more than Marco
Step-by-step explanation:
w=9h
H is a variable
9×hour= wage
9×15= $135
9×18= $162
157.50-135=$22.50
189-162=$27
27-22.50=4.50
Now cause its per hour we know she earns $4.50 more in 3 hours.
4.50÷3=$1.50
Answer:
4.7 lbs or 4 lbs 7 oz
Step-by-step explanation:
Add together:
1.6 lbs vegetables
2.3 lbs meat
.8 lbs condiments
