Answer:
b=4
Step-by-step explanation:
4b+5=1+5b (subtract 4b on both sides to get the b's together)
-4b -4b
5=1+5b-4b (subtract 1 from both sides)
-1 -1
4=1b (divide by 1)
b=4
Answer:
(3/2, 0+), (-1, 0+)
Step-by-step explanation:
An exact "zero" of a polynomial is characterized by a point on the x-axis. In this case the best approximation to that is the point (3/2, 0+); the next best approximation is (-1, 0+). Note that neither of these two points actually lies on the x-axis, but that both are closer to the x-axis than are any of the other given points.
-3/2 times -5 1/4 is equal to -1.5 times -5.25 which equals about 7.88 or 1 7/8
y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1
Could you please take a better picture I can’t really see it
