If you mean unit rate you find it by dividing the top number by the bottom number to fin the singular number or unit rate.
-y=8x
Since slope intercept form is the form: y=mx + b
And <span>-y=8x is basically -y=mx
All you have to do is divide -y by -1 so that the negative of the variable goes away.
Final Answer: y= -8x</span>
Answer:
(3x+4)(5x+7)
Step-by-step explanation:
15x^2
+41x+28
Factor the expression by grouping. First, the expression needs to be rewritten as 15x^2
+ax+bx+28. To find a and b, set up a system to be solved.
a+b=41
ab=15×28=420
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 420.
1,420
2,210
3,140
4,105
5,84
6,70
7,60
10,42
12,35
14,30
15,28
20,21
Calculate the sum for each pair.
1+420=421
2+210=212
3+140=143
4+105=109
5+84=89
6+70=76
7+60=67
10+42=52
12+35=47
14+30=44
15+28=43
20+21=41
The solution is the pair that gives sum 41.
a=20
b=21
Rewrite 15x^2
+41x+28 as (15x^2
+20x)+(21x+28).
(15x^2
+20x)+(21x+28)
Factor out 5x in the first and 7 in the second group.
5x(3x+4)+7(3x+4)
Factor out common term 3x+4 by using distributive property.
(3x+4)(5x+7)
Answer:
===================
Solved by graphing: x =~ 3.711448
-----------
You can use a graphing calculator, or numerical
Answer:
40 inches tall
Step-by-step explanation:
h=5 w=12
5:12
so to increase to 96 inches wide and find height we can use the known ratio and arrive at...
40:96
h=40 w=96
