Answer:
x=75
Step-by-step explanation:
Hey There!
If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle
So essentially what I'm saying is that
2x-5=70+x
step 1 add 5 to each side
-5+5 cancels out
70+5=75
now we have
2x=70+x
step 2 subtract x from each side
x-x cancels out
2x-x=x
we're left with
x=75
Answer:
None of the above.
Step-by-step explanation:
The system of equations which should have the same solution as the system below;
x + 4y = 11
4x + 2y = 16
is
x + 4y = 11
-8x - 4y = - 32
This system of equations is missing from your choices.
The trick is that -2 is multiplied to the second equation of the first system.
i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32
Eight times fifty one is 408
Answer:
7 x - y = 48 is the required line equation.
Step-by-step explanation:
Here,the two given points are A(6,-6) and B(8,8).
Now, the slope of the line with points (x1,y1) and (x2,y2) is given as:
So, here the slope of the given line is
or , m = 7
Now, by POINT SLOPE FORMULA:
The equation of a line with point (x0,y0) and slope m is given as:
(y- y0) = m (x -x0)
⇒ Here, the equation of line with (8,8) is y - 8 = 7 (x -8)
or, y - 8 = 7 x - 56
or, 7 x - y = 48 is the required line equation.
Remember y = ax^2 + bx + c
That means a = 1, b= 2 and c = -6
