Answer:
b = -8
Step-by-step explanation:
-2b + 9 =25
-9 = -9
-2b = 16
/-2 /-2
b = -8
Answer: equation equals to the 7th power of the point from the excellence of the number
Step-by-step explanation:
Answer:
See attachment for graph
Or
The slope intercept form is 
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as

Then we need at least two points on this line
When we compare to the point-slope formula
then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:



Answer:
3x - 3
Step-by-step explanation:
The sum is 10s^2t-5st^2. With two separate sections it’s a binomial, and the sum of the powers of the variables is 2+1=3, it has a degree of 3.
