Step-by-step explanation:
<u>Given:</u> XW is an altitude
m∠XWY=8x-6
<u>Prove:</u> x=2
<u>Solution:</u>
Statement Reason
1. XW is an altitude Given
2. m∠XWY = 90° Definition of altitude
3. m∠XWY = 8x - 6 Given
4. 8x - 6 = 90 Substitution property
5. 8x - 6 + 6 = 90 + 6 Addition property of equality
8x = 90
6. x = 12 Division property of equality
You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
Answer:
Step-by-step explanation:
acute ks little angles
obtuse is big angles
in a riangle it adds up to 180
Answer:
No solution
Step-by-step explanation:
by criss cross method, 6(x+3) = 6(4+x)
6x+18 = 24+6x
6x-6x = 24-18
0=6 no solution
We can think of this as an equality
5 Lawns = 8 Hours
If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:
5 x (5) = 8 x (5)
Therefore she mows 25 Lawns in 40 Hours
