Answer:
The leading coefficient is -3
The constant is 2
Step-by-step explanation:
The standard form of a polynomial is the descending order, that means that it must be written according from its higher power, down straight to the coefficient with no variable.
Hence, the leading coefficient is the one that is next to the highest exponent of the polynomial, in this case: =3x2.
The second term is 5x
And the last is 2. the constant
Yes because 84+45 is 129 and 3(28+15) is 129
Answer:
The x-intercept is (18/5, 0).
The y-intercept is (0,-2).
Step-by-step explanation:
To find the <u>x-intercept</u>, sub y for 0.
-5x + 9y = -18
-5x + 9(0) = -18
Simplify and isolate x.
-5x = -18 <= Divide both sides by -5
x = 18/5
Since we substituted y for 0, y=0.
(18/5, 0)
To find the <u>y-intercept</u>, sub x for 0.
-5x + 9y = -18
-5(0) + 9y = -18
Simplify and isolate y.
9y = -18 <= Divide both sides by 9
y = -2
Since we substituted x for 0, x=0.
(0,-2)
