Answer:
Step-by-step explanation:
C is the correct answer. Multiply each element of the matrix by -3:
-3(2) = -6, and so on.
Answer:
y= 1/2x + 17/2
Step-by-step explanation:
First, find your slope using y-y1/x-x1. This is your expression: 10-6/3--5. 10-6 equals 4, and 3--5 equals 8. Your slope is 4/8, but it can be simplified to 1/2. This should be your current equation: y=1/2x+b. Plug in one of your ordered pairs to the equation, it doesn't matter which pair you want to use. I'm using the second ordered pair, so this is what you would have: 10=1/2(3)+b. Multiply 1/2 by 3 to get 3/2. This is what it should look like: 10=3/2+b. Subtract 3/2 from both sides to get your y-intercept of 17/2. Go back to your original equation and plug in your y-intercept. This is your final answer: y= 1/2x + 17/2. Hope this helped!
2(x+12x) = 2x + 24x
2x+24x - 2x2= 2x+24x - 4
2x + 24x = 26x
26x - 4 is your answer
Answer:
Step-by-step explanation:
Let the angles which are in ratio be 5x and 7x respectively.
Now,
5x + 7x = 180
=> 12x = 180
=> x = 15
Hence the measure of both the angles are 75 degree and 105 degree.
