Answer:
x=18
QR=29
RS=29
QS=29
Step-by-step explanation: 2X-7=5x-61=x+11 solve for x since all sides are equal
Answer:
cos(400)
Step-by-step explanation:
Useful things:
Cofunction identity: sin(x)=cos(90-x)
Sine and cosine have period of 360 degrees.
So sin(50)=cos(40) by cofunction identity.
Since cosine has period of 360 degrees then cos(40)=cos(360+40).
That simplifies to cos(400).
Correct answer: y = 
x + 2
To find out the slope, you would need to remember this slope formula: 
. We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as 
and 
, and (0, 2) as 
and 
. Now we can plug these numbers into the slope formula to find out the slope:
m = → 
→ 
→
To find out the y-intercept, just substitute (3, 3) into the slope-intercept<em> </em>formula ( <em>y = mx + b</em> ) with the slope that is substituted for '<em>m</em>' that we already solved earlier.
y = mx + b
(3) = (3) + b
3 = 1 + b
2 = b
You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.
Now we know that m = and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y = x + 2.
