Answer:
Step-by-step explanation:
F(x) is another name for y
If you make a table of values, you can plot the coordinates of this quadratic equation.
When "x" is 0, y is 3
-5.9, -5 7/8, 5.78 because negative is less than zero and 7/8= .850 :)
Answer:30
Step-by-step explanation:the initial statement is
y ∝ x
to convert to an equation multiply by k the constant
of variation
⇒ y = k x
to find k use the given condition
y = − 24 when x = 8 y = k x ⇒ k = y x = −22
∣
∣
∣22 y = − 3 x 22
∣∣∣
−−−−−−−−−−−−−−
when x = 10
then y = − 3 × 10 = −30
I believe it is 150º because a supplementary angle is 180º so 180-30=150.
Answer:
one solution : (2,2)
Step-by-step explanation:
hello :
the system is : x-2.6y=-3.2
....(*)
-x+4.5y=7.....(**)
add(*) and(**) : -2.6y+4.5y = -3.2+7
1.9y=3.8
y = 3.8/1.9 =2
put this value in (*) : x - (2.6)(2) =-3.2
x =(2.6)(2) -3.2 =2
one solution : (2,2)
