Answer:
The correct answer is D. The points are rotated 180 degrees and scaled by a factor of 0.5. I assume that the 0.5 is the expected value in the text box labelled "D" (for dilation perhaps?)
Answer:
Based on the linear relation shown above, when the y coordinate is 3, the x coordinate is 8.
Step-by-step explanation:
This is because every time you add an input of 2, you subtract an output of 4.
Basically in the x value you add 2 while in the why value you subtract 4.
(2, 13) (4, 9) (6, 5) (8, 1)
Answer:
we have to be able to read it first tho. we can't see what the problem is so we need to see it please and thank you...
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
Answer:
and 
Step-by-step explanation:
The LCM of 35 and 10 is 70.
35×2=70
10×7=70
You got to multiply 3 with 2 and 1 with 7 to make 6/70 and 7/70.
