Answer:
Step-by-step explanation:
A rotation of -90 degrees about the origin is equivalent to a clockwise rotation. Point A, initially at (2, 0), would become point A', (0, -2).
X-6= units digits
X= tens digit
4(x)+5(x-6)=51
9x-30=51
9x=81, x=9
Plug x back into top equation:
9-6=3, units digit is 3
X=9, tens digit is 9
The two digit number =93
Answer:
19.2
Step-by-step explanation:
Okay, so if we slice this rectangle in half along the diagonal, we see that we can use the Pythagorean Theorem, a^2+b^2=c^2 to find the length of the diagonal. 12^2+15^2=369. The square root of 396 is 19.20937... rounded to the tenths is 19.2.
Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
Answer:
y=-4x+2
Step-by-step explanation:
The slope intercept form is: y=mx+b
Then
y=-4x+b
y=2 and x=0 at the intercept
thus
2=-4(0)+b
b=2
y=-4x+2
