The perimeter of a child's rectangular sandbox is 18 feet. Part A:if the length of the sandbox is one foot longer than the width, write an equation that can find the length and width of the sandbox. Part B:using your equation from part a, find the dimensions of the Childs sandbox. Show your work
Answer:
Length = 5 feet
Width = 4 feet
Step-by-step explanation:
Perimeter of the sandbox = 18 feet
Perimeter of a rectangle = 2(length + width)
the length of the sandbox is one foot longer than the width
Let
Width = x
length = x + 1
Perimeter of a rectangle = 2(length + width)
18 = 2{(x+1) + x}
18 = 2{x + 1 + x)
18 = 2(2x + 1)
18 = 4x + 2
4x = 18 - 2
4x = 16
Divide both sides by 4
x = 16/4
= 4
Width = x = 4 feet
length = x + 1
= 4 + 1
= 5 feet
Use the vertical line test to determine whether or not the graph is a graph of a function.
Answer:
25. Not a function because when you use vertical line test, you came across two points at the same time.

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x
+1?
Oright 1 unit
o left 1 unit
Oright 2 units
left 2 units
Answer:
The translation is left 1 unit, up 5 units ⇒ A
Step-by-step explanation:
Let us revise the rules of translation of a function
If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = and k = f(h)
You will use the vertex form to find the translation
∵ g(x) = x² + 2x + 6
∴ a = 1 and b = 2
→ use the rule of h to find it
∴ h =
∴ h = -1
→ Use it to find k
∵ g(h) = k
∴ k = g(-1)
→ Substitute x by -1 in g to find k
∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6
∴ k = 5
→ Substitute the values of h and k in the vertex form above
∴ g(x) = 1(x - -1)² + 5
∴ g(x) = (x + 1)² + 5
→ By using the 2nd and 3rd rules of translation above
∴ f(x) is translated 1 unit to the left and 5 units up
∴ The translation is left 1 unit, up 5 units
Answer:
it's A. left 1 unit

Write the absolute value equation that has these two solutions x= (-8,22)
Answer:
8,22
Step-by-step explanation:
the slope of the line is below 2. use the coordinates of the labeled point to find a point-slope equation of the line.
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (1, 9) , thus
y - 9 = 2(x - 1) → C
Determine the value of y, if x is-6.
y= |x|+ 6
Answer:
Answer:
y = 12
Step-by-step explanation:
The two bars between x mean absolute value, so all negatives turn into positives because absolute value just means the total distance from zero.
y = |x| +6
y = |-6|+6
y = 6+6
y = 12

At the movies, Hunter bought 3 popcorn and 5 drinks. Each popcorn
costs $0.40 less than a drink. If he spent a total of $24.00, what was the
cost of each popcorn?
Step by step explanation pls!!!!
Answer:
P= $2.75
Step-by-step explanation:
So first we need to create our system of equations
since each popcorn is 0.40 less than each drink we can make the equation:
D - 0.40 = P we can rewrite that as P + 0.40 = D so that we have D by its self.
Next, we create the overall equation:
$24.00 = 3P + 5D
Now plug in D from the first equation into the second equation:
$24.00 = 3P + 5( P + 0.40)
Distribute the five and solve for P:
$24.00 = 3P + 5P + 2
$22.00 = 8P
P = $2.75
Now add 0.40 which would be $3.15 and plug it into the first equation just to make sure that the answer is correct.

Answer:
x = 8
Step-by-step explanation:
Given
3(x + 1) + 6 = 33 ( subtract 6 from both sides )
3(x + 1) = 27 ( divide both sides by 3 )
x + 1 = 9 ( subtract 1 from both sides )
x = 8

Match each solution to the equation it solves.
Answer:
the first one is 3
the second one is 7
the third one is -2
and the last one is -3
Step-by-step explanation:
The equation is matched with its solutions below;
1/4x + 5/3x - 4 = 2 - 1/12x; x = 33.2b - 4.7 = 3b - 3.3; b = 74.6y - y + 4 = y - 1.2; y = -27.5c - 2.5c + 8 = - 7; c = -3What is the solution to the equation?1/4x + 5/3x - 4 = 2 - 1/12x
combine like terms
1/4x + 5/3x + 1/12x = 2 + 4
(3x+20x+x) / 12 = 6
24/12x = 6
2x = 6
Divide both sides by 2
x = 6/2
x = 3
3.2b - 4.7 = 3b - 3.3
combine like terms
3.2b - 3b = -3.3 + 4.7
0.2b = 1.4
divide both sides by 0.2
b = 1.4 / 0.2
b = 7
4.6y - y + 4 = y - 1.2
combine like terms
4.6y - y - y = - 1.2 - 4
2.6y = - 5.2
divide both sides by 2.6
y = -5.2 / 2.6
y = -2
7.5c - 2.5c + 8 = - 7
5c = -7 - 8
5c = -15
divide both sides by 5
c = -15/5
c = -3
