17. A gardener is installing a fence around his garden. Let x represent the width of
the garden, in feet. The perimeter of the graden is 8x + 8. Which expression
represents the length of the garden?
a. 2x + 2
b. 3x +4
c. 6x + 8
d. 8x + 8 - 2x
Hey there!
Answer:
B. 3x + 4 ft.
Step-by-step explanation:
Remember that:
Perimeter of a rectangle: P = 2l + 2w
Given:
P = 8x + 8
w = x.
Plug the given information into the equation:
8x + 8 = 2l + 2x
Subtract 2x from both sides:
6x + 8 = 2l
Divide both sides by 2:
(6x + 8)/2 = 2l/2
3x + 4 = l.
Therefore, the length of the garden is:
l = 3x + 4 ft.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
Answer:
(10, 14)
Step-by-step explanation:
To solve this system let's use substitution:
Solve the first equation for x, obtaining x = 24 - y, and then substitute 24 - y for x in the second equation:
3(24 - y) + 5y = 100
Performing the indicated multiplication, we get:
72 - 3y + 5y = 100
Combining like terms results in 72 - 100 = -2y, or -28 = -2y
Thus, y must be 14.
If y = 14, then the first equation tells us that x = 10.
Check: Is this true? 3(10) + 5(14) = 100 YES
The solution is (10, 14).

I WILL GIVE BRAINLIEST TO BEST EXPLANATION!! How many 6-digit numbers, formed using each digit from 1 to 6 exactly once, are divisible by 6?
Answer:
There are 360 such numbers.
Step-by-step explanation:
The number of 6-digit numbers, formed using each digit from 1 to 6 excactly once, means we can have numbers like
123456, 123465, 123546,123564,.... 654321
The number of such numbers is given by 6! because we have a choice of 6 numbers for the first digit, 5 left for the next, ... until the last digit has only one choice.
6! = 6*5*4*3*2*1 = 720
We know that 1+2+3+4+5+6 = 21 is divisible by three, so all 720 numbers are divisible by 3.
However, to be divisible by six, we need a number divisible by three AND divisible by two.
Thus, out of the 720 numbers, we need count only the even numbers, which are exact half of the 720, or 360.
Therefore there are 360 6-digit numbers, formed using each digit from 1 to 6 exactly once, are divisible by 6.
Answer:
360 numbers
Step-by-step explanation:
6-digit numbers => the numbers have the form abcdef
f 3 values, f = {2; 4; 6}
a 5 values; b 4 values, c 3 values, d 2 values, e one value,
=> 5 * 4 * 3 * 2 * 1 * 3 = 360 numbers

The area of trapezoid RSTU is 68 square inches, and the area of similar trapezoid JKLM is 425 square inches. What is the scale factor of RSTU to JKLM?
Answer:
6.25
Step-by-step explanation:
The scale factor is equal to how many times larger or smaller the new trapezoid is from the original trapezoid. To solve for the scale factor, divide the new area of JKLM by the original area of RSTU to calculate how many times larger RSTU got to become JKLM.
425 ÷ 68 = 6.25

NB: I've tried several numbers; So, I'll just stick to the one that works
To start with;
Select ->11
Add 7 to 11: 11 + 7 - > 18
Add 7 to 18: 18 + 7 -> 25
With the above illustration, we've successfully used three numbers (11, 18 and 25) to form a new progression and the rule is to add 7
which inequality is graphed on the coordinate plane?
Answer:
B.
Step-by-step explanation:
The line is a dotted line, so the inequality is obviously going to be using either a > sign or a < sign.
The inequality is shaded above the dotted line, so we will use a > sign. That corresponds to Choice B.
Hope this helps!
The equation of the graph of inequality is y > 4x + 2.
What is graph of inequality?The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.
According to the question
Graph show the inequality
As graph is having a doted line
as we know
The boundary line is dashed for > and < in graph of an inequality
i.e
inequality will have either > or <
Now ,
As we know according to the graph of an inequality
If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.
As area is shaded above the line
i.e it will have
>sign in inequality
As per options
only option B is valid which have > sign in inequality .
Therefore,
the equation of the graph of inequality is y > 4x + 2.
Hence, the equation of the graph of inequality is y > 4x + 2.

Using the equation y = 2x + 5 , what would the input need to be for an output of -45?
a. -20
b. -25
c. -85
d. -95
Answer:
-25
Step-by-step explanation:
Essentially, y is your output and x is your input.
Here's your base equation: y = 2x + 5
Knowing the information above, let's plug it in:
-45 = 2x + 5
(Subtract 5 from both sides)
-50 = 2x
(Divide both sides by 2 to isolate x)
-25 = x
And there you go.
Answer:
input is -25
Step-by-step explanation:
y = 2x + 5
The output is -45 which is y
-45 = 2x + 5
Subtract 5 from each side
-45-5 = 2x
-50 = 2x
Divide each side by 2
-50/2 = 2x/2
-25 = x
