Answer: The coordinates of point B are (19 , 20).
Step-by-step explanation:
The mid point (x,y) of line joining (a,b) and (c,d) is given by :-
(1)
Given : Point A is located at (3,6). The midpoint of line segment AB is point C(11,13).
Let the coordinates of point B are (a,b) m, the according to (1) , we have
Hence, the coordinates of point B are (19 , 20).
Step-by-step explanation:
here as base are same
-x= 6x-9
=> -7x= -9
=> x = 9/7
Answer: $1.33
Step-by-step explanation: you have one dollar. One quarter is 25 cents. One nickel is 5 cents. And 3 pennies is 3 cents so you add 25+5+3=33 and you add that to one dollar and you get $1.33.
Q + n = 91
q +n -n =91-n
q= 91-n
.25q +.05n = $14.55
.25(91-n)+.05n = $14.55
22.75-.25n+ .05n= $14.55
22.75 -.20n =14.55
22.75-22.75-.20n=14.55-22.75
-.20n=-8.2
-.20n/-.20n= -8.2/-.20n
n= 41
q + 41 = 91
q +41 -41 = 91-41
q = 50
CHECK
.25(50) + 0.05(41) = $14.55
12.50 + 2.05 = $14.55
$14.55 = $14.55
The slope-intercept form: y = mx + b
m - slope
b - y-intercept
We have -1/2(x + 4) = y - 2 <em>use distributive property</em>
(-1/2)(x) + (-1/2)(4) = y - 2
-1/2 x - 2 = y - 2 <em>add 2 to both sides</em>
-1/2 x = y → y = -1/2 x + 0
slope: m = -1/2
y-intercept: b = 0
x-intercept for y = 0. Substitute:
-1/2 x = 0 <em>multiply both sides by -2</em>
x = 0
<h3>Answer:</h3><h3>slope = -1/2</h3><h3>y-intercept = 0</h3><h3>x-intercept = 0</h3>
--------------------------------------------------------------------
2x - y = 4 <em>sutract 2x from both sides</em>
-y = -2x + 4 <em>change the signs</em>
y = -2x + 4
slope: m = -2
y-intercept: b = 4
x-intercept for y = 0. Substitute:
-2x + 4 = 0 <em>subtract 4 from both sides</em>
-2x = -4 <em>divide both sides by -2</em>
x = 2
<h3>Answer:</h3><h3>slope = -2</h3><h3>y-intercept = 4</h3><h3>x-intercept = 2</h3>
