Answer:
The equation is y = (2/3)x + (4/3).
Step-by-step explanation:
First, you have to change the equation into slope-intecept formula to find its gradient (slope) :



Given that when a line is perpendicular to the other line, their slope value multiplied, will form -1. Next, we have to find the slope for line :




Lastly, we have to subatitute the x and y values into the equation, to find its intercept value :






The answer is a = 132.93 cm2
Answer:

Step-by-step explanation:

Answer:
X = 40
Explanation: (2x) = 80
80/2 = 40
X = 40 degrees
Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
