Answer:

range {3, 5, 6, 7 }

Step-by-step explanation:

to find the range substitute each value of x from the domain into f(x)

f(- 3) = -(- 3) + 4 = 3 + 4 = 7

f(- 2) = - (- 2 + 4 = 2 + 4 = 6

f(- 1) = - (- 1) + 4 = 1 + 4 = 5

f(1) = - 1 + 4 = 3

range y ∈ { 3, 5, 6, 7 }

Answer:

B. $x^2+11x+24\leq 150$

Step-by-step explanation:

Step 1) Defining Sue and Jeremy's ages using x

Sue is 3 years older than Holly (h):

$h=x+3$

Jeremy is 5 years older than Sue, or 8 years older than Holly (j):

$j=x+8$

Product of Jeremy and Sue's ages is less than or equal to 150:

$hj\leq 150$

Step 2) Simplifying into a single equation

Using the equation above we can substitute Sue and Jeremy's ages:

$(x+3)(x+8)\leq 150$

Now we can simplify this equation. Use the distributive property first:

$x(x+8)=x^2+8x\\3(x+8)=3x+24$

Now add all the terms together and get the final answer:

$x^2+8x+3x+24\leq 150\\x^2+11x+24\leq 150$

Final equation: $x^2+11x+24\leq 150$

Express 148.502 in standard form Pls as soon as possible

LenKa [72]

Answer:

1.48502 × 10²

Step-by-step explanation:

A number expressed in standard form is

a × $10^{n}$ ( 1 ≤ a < 10 and n is an integer )

Given

148.502 ← express as a number between 1 and 10

1.48502

To obtain the original number we require to multiply by 100 , that is 10²

Thus

148.502 = 1.48502 × 10²

If f(x)=(3+x)/(x-3), what is f(a+2)?

tigry1 [53]

Answer:

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,

f(a + 2) = (3 + a + 2) / (a + 2 - 3)

Simplifying the function generated above,

f(a + 2) = (5 + a) / (a - 1)
