Match each quadratic function to its graph.
A: f(x) = -2(x + 3)2 − 1
B: f(x) = -2(x + 3)2 + 1
C: f(x) = 2(x + 3)2 + 1
D: f(x) = 2(x − 3)2 + 1
Answer:
f(x) = 2(x + 3)² + 1 corresponds to graph C.
f(x) = -2(x + 3)² + 1 corresponds to graph D.
f(x) = 2(x - 3)² + 1 corresponds to graph A.
f(x) = -2(x + 3)² - 1 corresponds to graph B.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
12x-20y= 60
help I need the answer
Answer:
[tex]y = \frac{3}{5}x - 3[/tex]
Step-by-step explanation:
To put this equation into slope-intercept form, we need to isolate y on one side of the equation.
First, we should move 12x to the right side of the equation. To do this, we need to subtract 12x from both sides.
12x - 20y - 12x = -20y (12x and -12x cancel out)
60 - 12x
We are left with;
-20y = 60 - 12x
To isolate y, we need to divide all the terms by -20.
-20y/-20 = y
60/-20 = -3
12x/-20 = [tex]\frac{12}{20}x[/tex]
[tex]\frac{12}{20}[/tex] can be simplified to [tex]\frac{3}{5}[/tex]
So, the equation we are left with is;
[tex]y = \frac{3}{5}x - 3[/tex]

D) f (-1) (x) = x³-12
Step-by-step explanation:
∛x+12
Interchange the variables and solve for y
∛y +12 =x
(∛x+12) ³= x³
y+12 = x³
y= x³-12
f (-1) (x) = x³-12

Answer:
Graph A is a function, and Graph B is not
Step-by-step explanation:
A function is when each x-value (aka input) has 1 corresponding y-value (or output).
We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.
However, Graph B curves, making it so some of the x-values have more than 1 y-value.

Answer:
80 lemons
Step-by-step explanation:
Let x represent the amount of lemons that were on the tree.
We can use this to set up an equation:
[tex]40\%x=32[/tex]
Note that percentages can also be written as that number over 100.
[tex]\frac{40}{100}x=32[/tex]
Simplify the fraction.
[tex]\frac{2}{5}x=32[/tex]
Multiply both sides by 5
[tex]2x=160[/tex]
Divide both sides by 2
[tex]x=80[/tex]
There were 80 lemons on the tree before he picked the lemons.
Candice knows it is made entirely from one metal. She is not sure if it is copper, silver or gold. Her bracelet has a mass of approximately 18 g. Metal Density (g/cm) Copper 8.96 Silver 10.49 Gold 19.32 Convince Candice that her bracelet is made from silver. You must show all your working.
Candice's bracelet is made from silver because the volume of her bracelet is; 1.72cm³
Density, Mass and VolumeBy definition, the density of an object is the ratio of its mass per unit volume.
Density = Mass/Volume.Hence, for silver;
10.49 = 18/Volume.Volume = 18/10.49Volume = 1.72cm³.

Today Arlene is one-fourth of Justin's age. In 10 years, Arlene will be 50% of Justin's ageHow old was Arlene last year?
Answer:
Step-by-step explanation:
Let Justin's age be x
Arlene today is 1/4 x
Ten years from now
Arlene: 1/2 (x + 10) = 1/4 x + 10 Remove the brackets
1/2 x + 5 = 1/4x + 10 Subtract 1/4x from both sides.
1/2 x - 1/4x + 5 = 10 Combine
1/4x + 5 = 10 Subtract 5 from both side
1/4 x = 10 - 5 Combine
1/4 x = 5 Multiply both sides by 4
x = 5 * 4
x = 20

the length of a rectangle is 2cm longer than its width. If the perimeter of the rectangle is 60 cm, find its length and width
Answer:
Let the Width(W) = X cm
then the length(L)= (2+X)cm
Perimeter(P)= 60cm
P =L+W
L+W =P
(2+X)cm +X cm = 60 cm
2X+2=60
2X=60-2
2X=58
dividing both sides by 2
X=29cm
Width =X
Width =29cm
the width is 29cm
Length= (2+X)cm
= (2+29)cm
= 31cm
the length is 31cm
We will let w represent the width of the rectangle (in centimeters).
We know that the length is 2 cm longer than the width.
So the length is w + 2 .
We can label the rectangle as follows.
The perimeter is given as 60 cm.
So we solve for w as follows.
w + (w + 2) + w + (w + 2) = 60
w + w + 2 + w + w + 2 = 60
4w + 4 = 60
4w = 56
w = 14
Using this value of w, we can find w + 2.
w + 2 = 14 + 2 = 16
ANSWER
length: 16 cm
width: 14 cm
