The first thing I'll do is solve "5y = 2x + 20" for "<span>y=</span>", so that I can find my reference slope:
y = (2/5)x + 4;
So the reference slope from the reference line is <span>m = 2/5;</span>.
Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line.
Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope <span>m = 2/5</span>. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);
Finally, y = (2/5)x + 17/5;
You just substitute the heights for H. 25 + 1.17(34) then find what that equals to the nearest inch and do the same for the boy
A. -8 Because there’s a negative in -4ac
Answer:
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 3 and 9 is 9
For the 1st fraction, since 3 × 3 = 9,
2
3
=
2 × 3
3 × 3
=
6
9
Likewise, for the 2nd fraction, since 9 × 1 = 9,
4
9
=
4 × 1
9 × 1
=
4
9
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
6
9
>
4
9
or
2
3
>
4
9
