a
Step-by-step explanation:
i just did it
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
Answer:
The exponent is 5 because a exponent is what the number times itself like 3^2 is 9.
To find how much each percentage is you need to make each one a fraction so 3/100 x 26000/1 your answer is 780 for 3 percent so her first raise makes it 26780 and 26000 plus 26780 is 52780 then keep adding 780 to 26000. So your answer would be A i think
Answer:
B) (x, - 3/2x + 2) for all real numbers
Step-by-step explanation:
since x can be any real number, there are infinite solutions for y= -3/2x+2 , so the answer is not C or D
for a given x, y can only be y= -3/2*x+2 , not any value y so the answer is not B
since for a given x , y can only be y= -3/2*x+2 the solutions will be (x , y = -3/2*x+2) or (x , -3/2*x+2 ) for all real numbers
