Answer:
7
Step-by-step explanation:
To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7
Answer:
The answer is B : 6
Step-by-step explanation:
2.50k means 2.50 multiplied by a number and the inequality means 20 is less than 2.50k + 5.50. 2.50 multiplied by 6 equals 15 and 15 plus 5.50 is 20.50 which is greater than 20.
Answer:
The greatest common factor of the terms is 1.
Step-by-step explanation:
The terms have no variables in common, and the coefficients have no factors in common. The greatest common factor of the terms is 1.

The discriminant is negative (40² -4(30)(51) = -4520), so any linear factors will be complex.
Answer:
y = -7/4x
Step-by-step explanation:
This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
