Answer:
4*+1
Step-by-step explanation:
To find
g
(
f
(
x
)
)
you must substitute
f
(
x
)
or
4
x
+
3
for each occurrence of
x
in
g
(
x
)
.
g
(
x
)
=
x
−
2
becomes:
g
(
f
(
x
)
)
=
(
4
x
+
3
)
−
2
g
(
f
(
x
)
)
=
4
x
+
3
−
2
g
(
f
(
x
)
)
=
4
x
+
1

Let me know if this helps :)
Answer:
NO this set is not equivalent
Step-by-step explanation:
Okay the way you find out if a pair of ratios are equal is you would divide the denominator and nominator with each other, so: 13/7 and 9/4. But sense the answer would be in decimal form and cant be simplified this wouldnt be considered equivalent. Also if you divide 7 by 4 you get a different answer than when you do 13 divided 9.
Answer:
x = - 2 or x = 5
Step-by-step explanation:
Given
3x² - 9x - 30 = 0 ← in standard form
Divide all terms by 3
x² - 3x - 10 = 0
To factor the quadratic
Consider the factors of the constant term (- 10) which sum to give the coefficient of the x- term (- 3)
The factors are - 5 and + 2, since
- 5 × 2 = - 10 and - 5 + 2 = - 3, thus
x² - 3x - 10 = 0
(x - 5)(x + 2) = 0
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 2 = 0 ⇒ x = - 2
