Answer:
B
Step-by-step explanation:
The equations are:
2x + y - 7 = 0
and
1/3x + y -4 = 0
Let's rearrange the first to get:
y = -2x + 7
Putting this into the 2nd equation we get:
Now, y would be:
Solving the equation we see that there is 1 unique solution with 1 x value and another y values. That means, when graphing, the lines would intersect.
Answer choice B is right.
<u>Note:</u> Coincident means the same line and parallel means there would be no solution when solving
It’s 3/10
because
6/2= 3
so we will have to use 2 again do we will multiply it times ten (10x2)to to get 20
so it will be 3/10
Answer:
x^2+2x
Step-by-step explanation: You would take x and multiply it by x and get X^2 then you would take x anm multiply it by 2 to get 2x. It is distributing
Answer:
145°
Step-by-step explanation:
There are a couple of ways you can get there:
1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...
... ∠BAC = 90° -∠ABC = 90° -55° = 35°
Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...
... ∠BAD = 180° -35° = 145°
2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.
... ∠BAD = 55° +90° = 145°
60w^5y^3= 2 x 3 x 10 x w x w^4 x y x y ^2
78wy^2= 2 x 3 x 13 x w x y^2
GCF= 2 x 3 x w x y^2 is 6wy^2
The answer is B. Hope this helps.
