Step-by-step explanation:
P=2W+2L
14x+8 =2(5x)+2L
14x+8=10x+2L
14x+8-10x=2L

(4x+8)/2=L
2x+4=L
Tell whether the lines through the given points are parallel, perpendicular, or neither.
Line 1: (-9,3), (-5,7)
Line 2: (-11, 6), (-7, 2)
The slope of line 1 is
The slope of line 2 is
The two lines are
Answer:
The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1
The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1
Yes, they are perpendicular
Step-by-step explanation:
The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1
The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1
slope 2 = - 1/1 = - 1/slope 1
can someone help me find x ?
Answer:
because AB = AC => angle B = angle C
=> 4x - 2 = 6x - 8
<=> 2x = 6
<=> x = 3

Which graph shows the solutions?
Answer:
Fourth graph
Step-by-step explanation:
Subtract 3 from each side, so it now looks like this: [tex]\frac{1}{2}n < 2[/tex] Divide each side by 1/2 to cancel out the 1/2 next to n. It should now look like this: n < 4Look at the graphs given. The fourth graph shows that the number could be anything under four. It has the circle on four, and the arrow going to the left of four (to represent the numbers less than four)I hope this helps!

Question 6 of 12 -
If ATUV is translated to image ATUV, as shown below, by the rule (x, y) - (x + 8, y - 3), what are the coordinates of ATUV?
Answer:
The coordinate point is horizontal translation right '8' units and follows that
the coordinate point is vertically down '3' units
(x,y) → ( x+8 ,y-3)
Step-by-step explanation:
Explanation:-
The coordinate point is horizontal translation right 'c' units
(x,y) → ( x+c ,y)
The coordinate point is horizontal translation right '8' units
(x,y) → ( x+8 ,y)
Next The coordinate point is vertically down 'd' units
(x,y) → ( x ,y-d)
Given the coordinate point is vertically down '3' units
(x,y) → ( x+8 ,y-3)

A clothing store is raising the price of all its sweaters by $3.00. What is an expression that could be used to find the new price of a sweater that originally cost d dollars? *
Answer:
x+3
Step-by-step explanation:
Answer:
Step-by-step explanation:
The expression would be d + 3.
You're raising $3 in every sweaters cost so d is the cost of the sweater and you add 3 to raise $3 in the price.

Solve each system of equations algebraically
1. y=x+5 y=6 2. y=x+12 y= -18 3. y=x-10 y= -12
Answer:
Step-by-step explanation:
ky=x+5y 62y=x
Step: Solvey=x+5yfor x:
y=x+5y
y+−x=x+5y+−x(Add -x to both sides)
−x+y=5y
−x+y+−y=5y+−y(Add -y to both sides)
−x=4y et's solve for x.
y=x+12y
Step 1: Flip the equation.
x+12y=y
Step 2: Add -12y to both sides.
x+12y+−12y=y+−12y
x=−11y
Answer:
x=−11y

Step-by-step explanation:
Greg buys apples, bananas, and kiwis from a fruit stand each week. The first week he pays $3.19 for 2 apples, 3 bananas, and 2 kiwis. The second week he pays $4.12 for 3 apples, 4 bananas, and 2 kiwis. The third week he pays $3.01 for 1 apple, 1 banana, and 4 kiwis. Choose the system of equations that can be used to solve for the number of apples,a, the number of bananas,b, and the number of kiwis,k.
Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
The system of equation that can be used to solve these scenario are 2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and 1a + 1b + 4k = 3.01.
What is a linear equation?A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.
We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.
Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,
2a + 3b + 2k = 3.19...(i)
0a + 4b + 2k = 4.12...(ii)
1a + 1b + 4k = 3.01...(iii)
We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

Find the measure of the arc. Please help!
Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°

45 and a third divided by one sixth and then write a sentence to show work and create multiplication of number
Answer:
272
Step-by-step explanation:
45 and a third = 45 1/3
one sixth = 1/6
hence:
45 and a third divided by one sixth =
= 45 1/3 ÷ 1/6
= 136/3 ÷ 1/6
We convert to multiplication by converting 1/6 to its reciprocal which is 6/1
Hence:
= 136/3 ×6/1
= 272
Anthony earns $6.00 per hour plus $0.25 for each combo deal he sells. Write an expression that shows how much money be earns in one hour.
Answer: [tex]\$\ (6x+0.25y)[/tex] per hour
Step-by-step explanation:
Given
Anthony earns [tex]\$\ 6\ per\ hour[/tex]
Plus [tex]\$\ 0.25[/tex] for each combo deals
Suppose he works for x hours and sells y combo deals
So total earning will be the sum of both
i.e. = [tex]\$\ (6x+0.25y)[/tex] in one hour
or [tex]\$\ (6x+0.25y)[/tex] per hour

Sam is 12 years older than Matt. Five years ago the
sum of their ages was 28. How old are they now?
Write a system of equations to represent this situation.
Define your variables
Answer: y=x+12
(y-5) + (x+5)=28, where x = present age of Matt ( in years).
and y= present age of Sam.
Step-by-step explanation:
Let x be the present age of Matt ( in years).
and Sam's present age = y years
5 years's ago,
Sam's age = y-5 years
Matt's age = x-5 years
As per given,
y=x+12 (i)
and (y-5) + (x+5)=28 ....(ii)
Required system of equations:
y=x+12
(y-5) + (x+5)=28, where x = present age of Matt ( in years).
and y= present age of Sam.
