Answer:
Step-by-step explanation:
1). For a point (0, -15),
Here x = 0, so the piece of function that applies,
f(x) = 4x - 15 (Since, x = 0 lies in the range -2 ≤ x < 4)
= 4(0) - 15
= -15
True.
2). Since, f(x) = [tex]-\frac{1}{4}x^{2}+6x+36[/tex] for x < -2
= 4x - 15 for -2 ≤ x < 4
Which shows a gap between these graphs.
Therefore, graph has a discontinuity at x = -2
True.
3). For x > 4,
f(x) = [tex]3^{x-4}[/tex]
For every input value of x in the interval (4, ∞), output values of the function will be increasing.
So this option is TRUE.
4). In the interval (-12, -2),
Function to be followed → f(x) = [tex]-\frac{1}{4}x^{2}+6x+36[/tex]
Graph of the given quadratic function opens downwards (Since, coefficient of x² is negative).
In this graph value of function first increases then decreases.
So the answer is FALSE.
5). Since, input values of the function 'f' varies from (-∞, ∞)
Therefore, domain of the function will be (-∞, ∞)
TRUE.

6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.
Point (2, 4)
Answers
Answer:
Step-by-step explanation:
Let x be the number of pants and y be the number of shirts
x + y = 6
20x + 15y = 100
multiply the first equation by -20
-20x -20y = -120
20x + 15y = 100
subtract the equations
-5y = -20
y = 4
replace y in equation 1
x + 4 = 6
x = 2

Answers
Answer:
Question a)
[tex]9^{3x+4}=27^{4x+3}[/tex]
[tex]x=-0.166[/tex]
Question b)
[tex]4^{3x}=2^{x+1}[/tex]
[tex]x=0.2[/tex]
Step-by-step explanation:
Question a)
Given the expression
[tex]9^{3x+4}=27^{4x+3}[/tex]
Taking log on both sides
[tex]log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)[/tex]
[tex]\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)[/tex]
[tex]3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)[/tex]
[tex]3x+4=1.5\times \left(4x+3\right)[/tex]
[tex]3x+4=6x+4.5[/tex]
[tex]3x=6x+0.5[/tex]
[tex]\frac{-3x}{-3}=\frac{0.5}{-3}[/tex]
[tex]x=-0.166[/tex]
Therefore, the value of x:
[tex]x=-0.166[/tex]
Question b)
Similarly, we can solve the 'b' expression
Given the expression
[tex]4^{3x}=2^{x+1}[/tex]
Taking log on both sides
[tex]log\left(4^{3x}\right)=log\left(2^{x+1}\right)[/tex]
[tex]3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)[/tex]
[tex]3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)[/tex]
[tex]3x=0.5\times \left(x+1\right)[/tex]
[tex]3x=0.5x+0.5[/tex]
[tex]2.5x=0.5[/tex]
Divide both sides by 2.5
[tex]\frac{2.5x}{2.5}=\frac{0.5}{2.5}[/tex]
[tex]x=0.2[/tex]
Therefore, the value of x = 0.2

Abe is buying wrapping paper.
He is shopping for the best deal.
Drag the rolls of wrapping paper in order from the least to the greatest unit cost in dollars per square foot.
red 12.5 square feet for $1.79
blue 40 square feet for $5.29
green 50 square feet for $8.49
orange 60 square feet for $6.00
Answers
Answer:
So you need to compute all the rates to see which is the best deal.
$1.79/12.5ft^2=$0.1432 per ft^2
$5.29/40ft^2=$0.13225 per ft^2
$8.49/50ft^2=$0.1698 per ft^2
$6/60ft^2=$0.10 per ft^2
So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.
