Explanation:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have <span>y=5x−8</span> and we can substitute this value of y in the other equation
<span>4x+3y=33</span>
<span>4x+3<span>(5x−8)</span>=33</span> we can solve now for x
<span>4x+15x−24=33</span>
<span>19x=33+24</span>
<span>19x=57</span>
<span>x=<span>5719</span>=3</span>.
y can be obtained from the first equation
<span>y=5x−8</span>
<span>y=5⋅3−8=15−8=7</span>
Then <span>x=3</span> and <span>y=7</span>.
Solve by factoring and using the principal of zero products 4x^2= -11x-6. Write it .... Let f(x) = x^3<span> + 3x ^</span>2<span>+ </span>4x<span> - 7 and g(x) = -7x^4 + 5x^</span>3<span> +x^</span>2<span> - 7.</span>
You should try to retake the picture can’t c anything
The measure of angle 3 is 103 because 3 angles in a triangle equals 180. 52+25= 77 and 180-77= 103.
The measure of angle 4 is 77 because angle 3 and 4 make a line and a line is 180 degrees. so therefor the angle is 77 degrees
