The first step in solving the problem is to distribute the 8. We know this because of the system or order of operations as well as the distributive property.
8(2+7c)=-19
16+56c=-19
The next step in solving is to isolate the variable, which we can do by performing the opposite operations of the values
16+56c=-19
-16 -16
56c=-35
/56 /56
c=-35/56
Finally, we should put our equation in simplest form.
c=-35/56
c=-5/8=-.625
Using the math above, we can see that the value of the variable is -5/8 or -.625.
Answer:
x = -26.3746, 11.3746
Step-by-step explanation:
Easiest and fastest way to solve for <em>x</em> is to graph x² + 15x - 300 and analyze where the graph crosses the x-axis.
Alternatively, you can use the Quadratic Formula to help solve for <em>x</em>.
1. Use Difference of squares: a^2-b^2=(a+b)(a-b)
(x+k)(x-k)=0
2. Solve for x and k
x=+-k
k=+-x

Answer:
No
Step-by-step explanation:
To solve this problem, plug the given coordinates in for x and y.
If x = -4 and y = 2, the inequality is 4(-4) + 5(2) < -7.
Evaluating 4*-4 and 5*2, the inequality becomes -16 + 10 < -7.
Evaluating -16 + 10, the inequality becomes -6 < -7.
-6 is not less than -7, so (-4, 2) is not a solution of the inequality.
