It is c because I had this question on the test
Answer:
x = 8, y = 4
Step-by-step explanation:
x = 3y-4
2x - 8 = 2y
x - 4 = y
x = y + 4
substitute top equation to this equation
3y-4 = y+4
2y = 8
y = 4
now substitute this into second equation
x = y + 4
x = 8
check answer with first equation
x = 3y-4
8 = 3(4) - 4
8 = 8; correct
Solution:
<u>We know that:</u>
<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>
<u>Cancel out the "2" by dividing it by 18.</u>
<u>Simplify the multiplication.</u>
Since all the terms have the same base you just deal with the exponents.
(X^2)(x^7)=x^9
X^9(x^-3)=x^9/x^3=x^6
Answer:
x = -2
Or
x = 4
Step-by-step explanation:
The solutions of the quadratic function that is represented by the graph shown above, is the x-intercepts of the graph.
The x-intercepts are the values of x, when y = 0. At any of these x-values, the parabola intercepts the x-axis.
Therefore, the graph shows that the parabola intercepts the x-axis when x = -2 and also when x = 4.
The solutions of the equation of the graph are x = -2, and x = 4.
