Answer:
Option K
m is an odd integer and n is an even integer
Step-by-step explanation:
The sum of intergers when one is even and another is odd results into an even number. Take for example, if x is even and the next number x+1 their sum will be 2x+1. The presence of +1 at the end shows the number is not divisible by 2 hence an odd number.
Practically, if you add 2+3=5 and 2 is even number while 3 is odd, clearly the sum being 5 is an odd number.
Otherwise, if you add two even numbers or two odd numbers the sum will be an even number.
Answer:
1
Step-by-step explanation:
Rise over run, for every time the y-value increases by one, the x-value also increases by one; 1/1=1. The slope formula is y2-y1/x2-x1.
Step-by-step explanation:
Since x² + kx + (k + 3) is tangent to the x-axis, the quadratic function has a repeated root.
The discriminant is zero, so b² - 4ac = 0.
=> k² - 4(1)(k + 3) = 0
=> k² - 4k - 12 = 0
=> (k - 6)(k + 2) = 0
Hence k = 6 or k = -2.
Answer: Yw :^
Step-by-step explanation: Present: Ishaan = Christopher + 20 - Equation 1
1 years back: Ishaan-14 = 3(Christopher-14) - Equation 2
Solve above equations:
I = 3c-42+14
I = 3c-24
I = c+20
2c-44 = 0
Christopher = 22 then from Equation 1
Ishaan = 22 + 20 = 42
