Answer:
Yes, it is 368.24, because you cannot use a digit more than once.
Step-by-step explanation:
Answer:
It i s 6
Step-by-step explanation:
Very six
The answer is A
You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated
-take the X in equation 2 and substitute in the first equation
So, You should have 5 (5-3/2 y) -4y =7
Get y ( I'll assume you know how to simplify and find y by yourself )
y=36/23
-Now take y and substitute it in the first equation or the second equation (it doesn't really matter)
Substituting y in Equation 2:
x=5- 3/2 (36/23)
=> x= 61/23
So answer is A where (x,y) is (61/23, 36/23)
I haven't got a calculator right now but substitute the values into the cosine law so:
8² = 5² + c² - (2 x 5 x c x cos58)
and then use sine law to find B
sin58/8 = sinB/5
Step-by-step explanation:
try the option shown in the attachment.
Finally,
in order to calculate the points E & F it is needed to solve the equations y=2*0+5 and 2x+5=0;
in order to calculate the vertex G it is needed to find x-coordinate:
x=(-4)/(2*1)=-2 and to substitute x=-2 into y=x²+4x-1 (y=-5).
