Answer:e
Step-by-step explanation:
total of interior angles for a 6 sided polygon = 720
150 + 152 + 91 +90+90 = 573
x = 720 - 573
x = 147
I’m pretty sure this prom or will always equal error but I do not know yet I will keep trying and get back to you if I find it
Answer:
Step-by-step explanation:
In a quadratic equation, a rule known as Vieta's Theorem tells us that roots 1 and 2 (we'll call them x1 and x2) added up is equal to -b/a, and x1 multiplied by x2 is equal to c/a. because x1-x2 is 6, and x1+x2=-b/a, which is -(-14), or 14, we can use the substitution method to find out the roots of the equation, being 4 and 10. When putting these roots into the equation, we get that 4^2-14(4)+q=0, and 10^2-14(10)+q=0. We can simplify these equations to make -40+q=0, and adding 40 on both sides gets us that q=40.
<u>To recap:</u>
Vieta's Formula:
use substitution to find the roots
enter the roots into the quadratic equation
solve the equation!
Answer: q = 40
Answer:
The answer is C, y = 1/4x - 4
Step-by-step explanation:
First, we have to find the slope of the perpendicular line, and to do so you must take the slope of the given line and opposite reciprocate it.
To do so, you first reciprocate the slope by flipping the numerator and denominator which now makes -4 into -1/4.
Then we have to make it the opposite value, like making a negative into a positive or a positive into a negative. In this case you make -1/4 into a positive 1/4.
We now have the slope of the perpendicular line and can make out answer choices A and B. Which now leaves us with C and D.
The line must go through the point (4, -3). To do that we must adjust the y-intercept until it goes though that point.
We get the y-intercept of -4 and the line that has the y-intercept of -4 and the slope of 1/4 is C.
You answer is C, y = 1/4x - 4.
