Answer:
2) x = 7
3) x = 5
Step-by-step explanation:
When a transversal crosses parallel lines, all of the acute angles are congruent, and all of the obtuse angles are congruent. When it crosses at right angle, all of the angles are right angles.
2) All of the angles are right angles.
11x +13 = 90
11x = 77 . . . . . . subtract 13
x = 7 . . . . . . . divide by 11
__
3) The two marked angles are acute.
16x = 80 . . . . the acute angles are congruent
x = 5 . . . . . . divide by 16
Answer:
30z^8
Step-by-step explanation:
5z^7.6z
= 5 x z^7 x 6 x z
= 5 x 6 x z^7 x z
= 30 x z^(7+1)
=30z^8
Answer:
Step-by-step explanation:
An inequality or equation for a graph is written in Y=MX +B form.
y and x are untouched while you need to do math to find M and B
M is the slope:
Slope is
how much you rise from one point to the next and how much you run from one point to the next. this graph gives us 2 points. (0,0) and (4,3)
to go from the first coordinate to the next you need to go up by 3 and over by 4 so 3over4.
This gives us
We still have to find B.
B is the y intercept. What Y position does the graph cross the Y Axis.
in this case it is at 0
so we put a zero for b.
last step: In our inequality we don't know if y is greater than or less than our equation.
The shading is under the line so Y is less than.
If it's over Than Y is more than...
Also we know that Y is less than some thing but not equal to it because the inequality is drawn as a dotted line not a solid straight one.
in this case Y is less than 3/4X + 0
Aka
1. Length = 8
2. 0.8
3. -0.8
