Answer:
x = - 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4
Equating to zero, that is
x² + 4x + 4 = 0 ← left side is a perfect square
(x + 2)² = 0, thus
x + 2 = 0 ⇒ x = - 2
D, the answer is the same but in the parenthesis is reversed using the addiction something property
Answer:
y = 1/4x -10
Step-by-step explanation:
The equation would be y = 1/4x -10
we know that we have to set the equation up as y=mx+b
m being slope and b being y-intercept
we can see on the graph that the line intercepts the y-axis at -10, so that would be b
for slope, you can just look and count rise over run so:
it goes 10 up and 40 over which equals 10/40 also known as 1/4
hope that helped :)
7+3= 10
Let's take 1,400 is to be seperated between A and B
Amount of money A will get = 1400* 7/10= 980
Amount of money B will get = 1400* 3/10= 420
Checking the answer:
980+420 = 1,400
Hence, 1,400 will be shared by ratio 7:3 is 980 and 420.
Correct me, if I am wrong :)
Have a great day!
Thanks!
