Ax+bx=4
x(a+b)=4
x = 4/(a+b)
Answer:
Step-by-step explanation:
Let 
be the quadratic function.
implies that 
Similarly, 
and 
From equation 2, 
Put (4) into (1) to get:
Put (4) in (3) to get:
Subtract (6) from (5) to get:
Put b=-3 in (4) to get:
a=--3-5=-2
Put b=-3 in to (6) to get:
-2(-3)+c=-3
6+c=-3
c=-6+-3=-9
Therefore the required equation is
Answer:
Let x be the number of hits Ricky has. Then x+277 is the number of hits Pedro has. Adding Ricky's and Pedro's hits give you 2685 hits. Therefore, x+(x+227)=2685 2x+227=2685 2x=2408 x=1204 x+277 1481 Therefore, Ricky has 1204 hits and Pedro has 1481 hits.
Step-by-step explanation:
There is no difference, both equal 40.
Answer:
The answer to your question is below
Step-by-step explanation:
9)
They are supplementary angle. The sum of supplementary angles is 180°.
b + 50 = 180
-Solve for b
b = 180 - 50
b = 130°
10)
They are vertical angles. Vertical angles measure the same
b = 43°
11)
They are vertical angles. Vertical angles measure the same.
b = 73°
12)
They are supplementary angles. The sum of supplementary angles is 180°
b + 35 = 180
-Solve for b
b = 180 - 35
b = 145°
