Mathematics
1 answer:
Gennadij [26K]3 years ago
7 0

Answer:

solve for x

x=2

Step-by-step explanation:

x2-20x-17=-53

reorder like terms x2= 2x       2x=20x-17=-53

collect like terms 2x-20x=-18x           -18x-17=-53

move constant to the right hand side and change its sign   -18x=-53+17

calculate the sum -53+17= -36         -18x=-36

divide both sides by -18  -18x÷-18= x        -36÷-18=2

x=2

irina [24]

The answer is D because The ordered pairs graphed are (2,3), (6,9), and (8,12). They all have a ratio of 2 to 3. Which means each point is 2 larger on the x-axis and 3 larger on the y-axis than the previous point. The point that is missing is (4,6) since 2 + 2 = 4 and 3 + 3 = 6.
