Split the second term 7x^2 - 8x - 12 into two terms
7x^2 + 6x - 14x - 12
Factor out common terms in the first two terms, then in the last two terms
x(7x + 6) - 2(7x + 6)
Factor out the common term; 7x + 6
<u>(7x + 6)(x - 2) </u>
Slope intercept form of a line is y=mx+b where m= slope and b=y-intercept.
Now compare this form with the tiven equation y=4x-9 to get the value of m.
So, m= 4.
Slope of all parallel lines are always equal. Which means the line which is parallel to this has also the same slope: m=4.
Now we need to find the value of b to get the equation. That parallel line passes through (-5,3).
The point intercept form of a line is,
(y-y1)=m(x-x1)
So, we can plug in the m=4, x1=-5 and y1=3 in the above equation. Hence,
y-3=4(x-(-5))
y-3=4(x+5) Since -(-5)=+5
y-3=4x+20 By distributing property.
y=4x+20+3 Adding 3 to each sides.
y=4x+23
So, the slope-intercept form of that parallel line is y=4x+23.
I need the following...
4y+24 would be the answer
--v---v
4(y+6) ... To get rid of parenthesis, simply multiply 4 by y, and 4 by 6.
4y+24 is the answer.
Step-by-step explanation:
1. add the numbers all together
(of the pets)
= 40 pets total
40 pets =100%
1 pet = 2.5%
percents:
Cat= 10, or 25%
Dog = 15, or 37.5 %
fish=8 or 20%
bird= 7 or 17.5%
angles:
dog= 135
cat= 90
fish= 72
bird= 63
Answer:
<em>d</em>= 4/7 or 0.571428
