Answer:
The slope is 9
The y intercept is (0,7)
Step-by-step explanation:
y=9x+7
The equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is 9
The y intercept is (0,7)
Answer:
find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
<h2>b=√112 = 4√7</h2>
the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
<h2>which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)</h2>
find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
<h2>a=9.87 rounded to the nearest hundredth</h2>
(i hope it is right )
Answer:
y = 3x + C
y = mx + 5
y = 3x + 5
Step-by-step explanation:
A. The standard form for lines with slope = 3 is
y = 3x + C where C is the y-intercept and can be any number
B. The standard form for lines with y-intercept = 5
y = mx + 5 where m is the slope and can be any number
C. The only line with slope = 3 and y-intercept =5
y = 3x + 5
There is only one line because both m and C are given.
Take 10% of $50, which is $5, and add it to the price of the shoes.
5 + 50 = 55
The total bill should be somewhere around $55.
