Answer:
(-4,2)
Step-by-step explanation:
First we have to find a common multiple to use to add and find the system of equations. We need to eliminate one of the variables in order to solve.
Since 5 * 3 = 15, and 3 * -5 = 15, -15x and 15x will cancel each other out. Therefore x will be eliminated.
Before:
5x + 2y = -16
3x + 7y = 2
After:
15x + 6y = -48 <----------Now we solve for y
-15x + -35y = -10
+----------------------
-29y = -58
-29 -29
y = 2
Now what we do is we choose and equation and solve for x, since it is still unknown. Any equation is fine but I will choose the second one since it has easy numbers.
3x + 7y = 2
3x + 7(2) = 2
3x + 14 = 2
-14 -14
----------------------
3x = -12
3 3
x = -4
Therefore our final answer is (-4,2)
C.
9987 × 1.04 = 10386.48
10386.48 - 1950 = 8436.48
8436.48 × .25 = 6327.36
Answer:
m= -1
Step-by-step explanation:
When writing an equation of a line, if I know more than one point, does it matter. The first method is to us the slope-intercept equation and plug in values to solve for b. 5. The slope-intecept equation would be y = 34 x + 2 (y−5)=34x−3 (isolate y). What is the equation in point-slope form of the line given (-2,3);
C = 4
Use the formula a^2 + b^2 = c^2
5 = a and 4 = b
