Answer and Step-by-step explanation:
The signs didn't really "swap". Instead, the whole function was divided by -1, or we could say the function was divided by -3. That would turn:
-18x² - 15x + 3 = 0
into
(-18 / -3)x² - (15 / -3)x + (3 / -3) = 0
6x² + 5x - 1 = 0
And that gives the "swapped signs".
Answer:
comparing both equation we get,
2X+1=X+9
or, X=8
Y=X+9
or, Y=17
therefore the required solution is (8,17)
Answer:
x= 251
Step-by-step explanation:
300x= 190x + 27,610
300x-190x= 27,610
110x= 27610
x= 27610/110
x= 251
Answer:
It is 
(12 × 4) = 24
Step-by-step explanation:
(base × height) = area of triangle
(12 × 4) = area
area = 24
Answer:
m<F=50
Step-by-step explanation:
complementary angles mean that together they equal 90, we need to set up an equation to find x, and then put x into angle F to find its measurement :)
m<C+m<F=90
(2x+10)+(x+35)=90
calculate to find x!
x=15
now we put 15 into (x+35)
15+35=50
hope this helps!! :D
