Two systems of equations are shown below:System A: 6x+y=2 -x-y=-3 System B: 2x-3y=-10 -x-y=-3 Which of the following statements is correct about the two system equations? A) The value of x for System B will be 4 less than the value of x for System A because the coefficient of x in the first equation of System B is 4 less than the coefficient of x in the first equation of System A. B) They will have the same solution because the first equations of both the systems have the same graph. C) They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A. D) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding -4 to the first equation of System A and the second equations are identical.

Sara leaves home at 7am traveling at a rate of 45 mi/h. her son discovers that she has forgotten her briefcase and starts out to catch up with her. her son leaves at 7:30 am traveling at a rate of 55 mi/h. At what time will he over take his mother?

Answers

Sara 45 mph
Son 55 mph
Sara 07:00
Son 07:30
Difference in time= 00:30 => 0.50 hours
Sara will have covered 22.50 miles Son starts

catch up distance= 22.50 miles
catch up speed = 55 -45
catch up speed = 10 mph
Catchup time = catchup distance/catch up speed
catch up time= 2.25
catch up time= 2.25 hours
They will meet at 9:55 am mph

Determine which polynomial has (x – 9) as a factor.

Answers

Answer:

option D

Step-by-step explanation:

(x-9) is a factor

x-9 =0 so x=9

now we plug in 9 for x and see which polynomial gives us remainder 0

A. x^2 - 6x +9 = 9^2 - 6(9) + 9 = 36

Remainder = 36 so (x-9) is not a factor

B) x^2 + 16x + 63= 9^2 + 16(9) + 63 = 288

Remainder =288 so (x-9) is not a factor

C) x^2 + 14x + 45= 9^2 + 14(9) + 45 = 252

Remainder = 252 so (x-9) is not a factor

D) x^2 - 12x + 27= 9^2 -12(9) + 27 = 0

Remainder = 0 so (x-9) is a factor
