Just solve the equations:
<span>A) X - Y = 11
B) 2x + Y = 19
Multiply A) by -2
</span>
<span>A) -2X +2Y = -22 then add to B)
</span><span>B) 2x + Y = 19
3Y = -3
Y=-1
</span>
<span>A) X - -1 = 11
x = 10
</span>
Answer:
Slope: 0
Step-by-step explanation:
We have to find the slope of the line with the given points.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.
Plug in your coordinates and solve.
Solve:
m = -7 - (-7)/-2 - 4
m = -7 + 7/-2 - 4
m = 0/-6
Divide -6 from 0.
m = 0
You would notice that we have a "0" in our slope. There is no "rise" in the slope.
This means that the slope of our line would be 0.
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 2 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3
Answer and Step-by-step explanation:
A) The first three terms are:
5, 8, 11
B) The tenth term is 32
You find the answer by plugging in the value for n. So for A), you would plug in 1, 2, and 3 (the first 3 terms), then to find the tenth term, you plug in 10 for n.

Answer:cos(53), cos 53 degrees
Step-by-step explanation: sin(angle)= cos(90-angle)
sin(37)=cos(90-37)=cos(53)
