Answer:

See below

Step-by-step explanation:

1) Solve the equation: [4ax - (a + b)](a + b) = 0, where a and b are constants.

if a + b = 0, then x has infinitely many solutions

4ax = a + b
x = (a + b)/4a, a≠0

2) Solve the equation m²x + 1 = m(x + 1), where m is a parameter.

m²x + 1 - mx - m = 0
(m²- m)x = m - 1
m(m - 1)x = m - 1
mx = 1
x = 1/m, m≠0

3) Given that the equation a(2x - 1) = 3x - 3 has no solution, find the value of the parameter a.

a(2x - 1) = 3x - 3
2ax - a = 3x - 3
2ax - 3x = a - 3
(2a - 3)x = a - 3
x = (a - 3)/(2a - 3)

<u>The equation has no solution if:</u>

2a - 3 = 0
2a = 3
a = 1.5

Which equation represents the function graphed on the coordinate plane? g(x) = |x + 4| – 2 g(x) = |x – 4| – 2 g(x) = |x – 2| – 4

Misha Larkins [42]

Answer:

$g(x)=|x+4|-2$

Step-by-step explanation:

All the absolute value functions given in the option are of the form:

$g(x)=|x-h|+k$ , where (h,k) is the vertex

From your description the absolute value graph has vertex at (-4,-2)

Hence h=-4 and k=-2.

We substitute to get:

$g(x)=|x--4|+-2$

We simplify to get:

$g(x)=|x+4|-2$

natita [175]

Answer: The pole is 17 feet long

Step-by-step explanation: If Matthew's shadow is 2 feet smaller than his actually size, the shadow of the pole will also be reduced. Since the pole's shadow is 15 feet long, adding 2 will give you its original size, 17 feet.

At the gym Merl swims every 6 days, runs every 4 days and cycles every 16 days. If she did all 3 activities today in how many da

garri49 [273]

Answer:

48 days

Step-by-step explanation:

Swim = every 6 days

Run = every 4 days

Cycles = every 16 days

Find the lowest common multiple of 6, 4 and 16

6 = 6, 12, 18, 24, 30, 36, 42, and 48

4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

16 = 16, 16, 32, 48, 64, 80, 96, 112, 128, 144, 160

The LCM of 6, 4 and 16 is 48

Therefore,

If she did all 3 activities today, she will do all 3 activities again in the next 48 days
