Answer:
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis) - Parallel lines always have the same slope
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
Given this equation, we can identify the slope to be -3 since it's in the place of <em>m</em> in .
Because parallel lines have the same slope, -3 is therefore the slope of the line we're currently solving for. Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Plug in the given point (1,5) and solve for <em>b:</em>
Therefore, the y-intercept is 8. Plug this back into :
I hope this helps!

Step-by-step explanation:
I would have to see the shape to see this but I could say the volume if you'd want. 5*6*7= 210. And don't forget; you can find the surface area by doing b x h if it's a rectangle. And if it's a triangle do b x h / 2

Answer:
D. 86°
Step-by-step explanation:
Points D and F divide the circle into two arcs. The long arc is labeled 274°, and the short arc is the one you're asked to find. You know the total of these two arcs is the full circle, 360°.
274° + DF = 360°
DF = 360° -274°
DF = 86°
__
There are other relationships you can use to find arc DF. One of the simpler ones is ...
DF and the external angle at E are supplementary:
DF = 180° -94° = 86°
