The answer is A because in the dotted line it corresponds to “y -3x-3”. You rise 3 and run only 1. The dotted line is going to the left because it’s a negative 3. The “y 1/3x-3” is the rise of 1 and the run of 3. Then place 0 into the x and y. Then once you place the 0 into both problems and if the problem is true then shade where the point 0,0 is. Since this problem is not true when placing 0 into the equation then you don’t shade where 0,0 is. Hopefully I explained this correctly.
Answer:
(1,1)
Step-by-step explanation:
M=(x1+x2 / 2 , y1+y2 / 2)
M=(-2+4 / 2 , 4+ -2 / 2)
M=(2 / 2 , 2 / 2)
M=(1,1)
Answer:
10.975+10.975+10.975+10.975
Step-by-step explanation:
1) x² + 8x + 15 = 0
Now what multiples to 15 and adds to 8? 5 and 3, 5x3=15, 5+3=8
so its
(x+5)(x+3)=0
now solve
x+5=0 x+3 =0
x = -5 x = -3
so the solution is -5, -3
4) x² - 11x + 28 = 0
what multiples to 28 and adds to -11? -7 and -4
(x-7)(x-4) =0
x= 7, 4
10) x² = 17x - 72 (okay ill do 3 of them)
first get numbers on same side where x² is positive
x² -17x + 72 = 0
what multiples to 72 and adds to -17? -9 and -8
(x-9)(x-8)=0
x= 9, 8
Independent variable: hours (t)
