<h3>
Answer: 1.8x - 4</h3>
==========================================================
Explanation:
Subtract the two expressions
Tomas - Angie = (3x) - (1.2x+4) = 3x - 1.2x-4 = 1.8x-4
This represents how many more miles Tomas jogged compared to Angie.
-------------
A more concrete example would be to say hypothetically
Tomas = 10 miles
Angie = 4 miles
So Tomas - Angie = 10-4 = 6 means he jogged 6 more miles than Angie.
That's why we subtracted. The order of subtraction matters. Saying 10-4 is different from 4-10.
A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
Answer: is very simple 26
Step-by-step explanation:
multiply and then divide the both numbers
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
