Step-by-step explanation:
J = 2b
M = J + 7
M = 21
J = 21 - 7
J = 14
B = 7
<em>Equation:</em>
If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.
Step-by-step explanation:
To find how many they can make in one hour simply divide both the amount of bagels they made by ten.
230 bagels = 10 hours
23 bagels = 1 hour.
Multiply this by twenty three
529 bagels = 23 hours
Answer:
System a will graph a pair of parallel lines.
Step-by-step explanation:
Both equations have the same slope.
<h3><em>(</em><em>sinx</em><em> </em><em>-</em><em> </em><em>cosx</em><em>)</em><em>^</em><em>2</em><em> </em><em>=</em><em> </em><em>(</em><em>sinx</em><em>)</em><em>^</em><em>2</em><em> </em><em>+</em><em> </em><em>(</em><em>cosx</em><em>)</em><em>^</em><em>2</em><em> </em><em>-</em><em> </em><em>2</em><em>s</em><em>i</em><em>n</em><em>x</em><em>c</em><em>o</em><em>s</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>-</em><em>2</em><em>s</em><em>i</em><em>n</em><em>x</em><em>c</em><em>o</em><em>s</em><em>x</em></h3>
Steps to find the equation
1. Find the slope
2. Insert slope into the general equation
3. Find y-intercept
4. Insert -intercept into the equation found in step 2
And you get the equation of the line
----------------------------------------------------------------------------------------------
Find the slope
----------------------------------------------------------------------------------------------
2y - x = 4
----------------------------------------------------------------------------------------------
Rewrite into the form y = mx + c
----------------------------------------------------------------------------------------------
2y = x + 4
y = 1/2 x + 2
Slope = 1/2
Perpendicular slope = -2 (negative reciprocal)
----------------------------------------------------------------------------------------------
Insert slope into the equation
----------------------------------------------------------------------------------------------
y = mx + c
y = -2x + c
----------------------------------------------------------------------------------------------
Find y-intercept
----------------------------------------------------------------------------------------------
y = -2x + c
At point (1, 2)
2 = -2(1) + c
2 = -2 + c
c = 4
----------------------------------------------------------------------------------------------
Insert y-intercept into the equation y = -2x + c
----------------------------------------------------------------------------------------------
y = -2x + 4
----------------------------------------------------------------------------------------------
Answer: y = -2x + 4
----------------------------------------------------------------------------------------------
