Answer:
option C
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.
y = ( x + 2) ( x - 3)
y = x ( x - 3)+2( x - 3)
y = x² - 3x + 2x -6
y = x² - x - 6
Now plot its graph. For that refer to attachment.
<u>Things </u><u>we </u><u>can</u><u> </u><u>interpret</u><u> </u><u>:</u><u>-</u><u> </u>
- The constant in the equation is -6. So the graph will cut y axis 6 units below the X axis . At (-6,0)
- From the given options , option C matches the above point .
<u>Therefore</u><u> the</u><u> </u><u>correct</u><u> </u><u>option</u><u> </u><u>is </u><u>(</u><u>C)</u><u> </u><u>.</u>
Answer:
WRS=25 degree
Step-by-step explanation:
Angle VRT + angle TRS = 180 degree (supplementary angles)
5x+25x+30=180
5x+25x=180-30
30x=150
x=150/30=5
Substituting x=5 into angle VRT
5(5)=25
VRT= 25 degree
Looking at the diagram, angle VRT and angle WRS are vertically opposite angle and are therefore equal.
Now, angle WRS= 25 degree
The answer is 85%.
If you're solving without a calculator, you can simply multiply the numerator and denominator so that the denominator is equal to 100. So, for this fraction, you would multiply both the top and the bottom by 5.
17/20
17(5) / 20(5)
85 / 100
85%
