The measure of angle DCE is C: 34.
7/16 is .4375, rounding to the nearest hundredth means you find the value that is two to the right of the decimal place, and use the 3rd number after as a basis to round it. Since 7 is greater then 5, you'll round the second number place up, putting your answer as .44, tack that onto the end of the 26 and you have 26.44 as your answer, or as a fraction, 26 11/25
Answer:
y = -x +4
Step-by-step explanation:
The y-intercept of the line is at +4, so the only viable choice is the last choice.
___
Each of the equations is shown in slope-intercept form:
y = mx + b
where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...
y = (some x-term) +4
If you want to spend more brain power on the problem, you can compute the slope of the line as ...
m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1
Now, you know for sure the equation of the line is ...
y = -x +4
5x + 100 = 3x + 112
(subtract 100)
5x = 3x + 12
(subtract 3x)
2x = 12
(divide by 2)
x = 6
