Answer:
3. D x÷y
4. B an irrational number
Step-by-step explanation:
3. When you divide a number, the answer is smaller than subtracting it, adding it, or multiplying it
4. 13-5=8 and the square root of 8 is 2.828...
Irrational numbers has infinite numbers
Y=8x+40
8 is slope because she adds 8$ weekly and 40 is what she started with
Gotta see a pic of the paper
Because the points are on the same line, the slope that is found using these points is the same
m1=m2
(y-y1)/(x-x1)=(y-y2)(x-x2)
(y-11)/(x+8)=(y-7/2)/(x-4)
(y-11)(x-4)=(y-7/2)(x+8)
yx-4y-11x+44 = yx +8y-(7/2) x-28
-4y-11x+44=8y-(7/2) x-28
8y+4y=-11x+(7/2)x+72
12y=-(22/2)x+(7/2)x+72
12y=-(15/2)x+72
y=-(15/(2*12))x+72/12
y=(-5/8)x+6 correct answer
