Answer:
2
Step-by-step explanation:
30y x 2 = 60y
Answer:
C
Step-by-step explanation:
To add the polynomials you can only add like terms. Like terms are terms that have the same variables and exponents. Only -5 and 4 are like terms. So leave the other terms alone.
The sum is 11x^2 + x - 1.
Answer:
3(4+12)=4(4x3)
Step-by-step explanation:
4+12=16;16x3=48;4x3=12;12x4=48
First transform the line into slope-intercept form (like the hint states)
8x-4y+15=0
8x+15=4y
2x+(15/4)=y
y=2x+(15/4)
so m of the given line is 2 and b=15/4
for two lines with m1 and m2, they are perpendicular if m1*m2=-1
-> insert the known m into m1:
2*m2=-1
m2=-1/2
so your new line is y=(-1/2)x+b
insert the point (3,4) it passes
4=(-1/2)*3+b
4=(-3/2)+b
11/2=b
y=(-1/2x)+(11/2)
