Answer:
line r: y=-2x-2
line s: -2x+1
lime t: -2x+3
Step-by-step explanation:
every slope must be -2 since that's stated in the question
to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)
basically, b is the y component when x is 0
The answer to question 1 is n=-17, and the answer to question 2 is y=-5.8 (<u>could also be seen as -29/8</u>)
Work is shown in the pictures below
The perimeter in 60 minutes is:
2 * pi * r
2 * pi * 8
50.26548246 inches
It moves from 12 to 2:
The perimeter will be:
(10/60) * (50.26548246)
Rewriting:
= (2/12) * (50.26548246)
= (1/6) * (50.26548246)
= 8.37758041
round to two-decimal places:
= 8.38 inches
Answer:
the top of the minute hand moves 8.38 inches
Answer:
| -6 0 |
| 12 21 |
Step-by-step explanation:
When we multiply a matrix by a scalar, each term in the matrix is multiplied by the scalar
3 | -2 0 |
| 4 7 |
becomes
| -6 0 |
| 12 21 |
