Answer:
E. y – 4 = 1(x – 3)
Step-by-step explanation:
Point slope form of a line is
y-y1=m(x-x1)
E is the only equation written in this form
E. y – 4 = 1(x – 3)
Answer:
Step-by-step explanation:
{у = 3х - 12
{4х + 6у = −6
4x + 6[3x - 12] = −6
4x + 18x - 72 = −6
−6 = −72 + 22x
+72 + 72
___________
66 = 22x
__ ___
22 22

Answer:
f[g(x)] = 4x²+1/16
Step-by-step explanation:
We need to put g(x) into f(x).
f[g(x)] = 1/(1/2x+4)²
f[g(x)] = 1/(1/4x²+16) Solve the exponential.
f[g(x)] = 1/(1/4x²+16) Simply the fraction.
f[g(x)] = 4x²+1/16
Answer:
Option (1)
Step-by-step explanation:
Given inequality is,
-4(x + 3) ≤ -2 - 2x
Further solve this inequality,
-4x - 12 ≤ -2 - 2x
-4x + 2x - 12 ≤ -2 - 2x + 2x
-2x - 12 ≤ -2
-2x - 12 + 12 ≤ -2 + 12
-2x ≤ 10
-x ≤ 5
x ≥ -5
Therefore, on a number line draw an arrow starting with a solid circle (because of equal to sign) and moving towards the numbers greater than -5.
Option (1) is the answer.
