HELP Solve for w x and y
Answer:
x = 24
PS = 45
Step-by-step explanation:
Perimeter of P Q R S is :
( 4x + 1 ) + ( 2x - 3 ) + ( 2x - 3 ) + 4 + ( 4x + 1 )
4x + 1 + 2x - 3 + 2x - 3 + 4 + 4x + 1
And in the question , given that the perimeter of this figure is 288.
Now let us find the value of x.
4x + 1 + 2x - 3 + 2x - 3 + 4 + 4x + 1 = 288
4x + 2x + 2x + 4x + 1 - 3 - 3 + 4 + 1 = 288
12x + 0 = 288
12x = 288
Divide both sides by 12
x = 24
And now let us find the value of PS
PS = 2x - 3
PS = 2× 24 - 3
PS = 48 - 3
PS = 45
Hope this helps you :-)

find the error!
Answer:
Step 1
Step-by-step explanation:
they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.
Answer:
B. Incorrect with error in STEP 1
Step-by-step explanation:
3x - x + 4 = 4(2x - 1)
Step 1: Simplify
2x + 4 = 8x - 4
Step 2: Subtract 8x from both sides.
2x+4−8x=8x−4−8x
−6x+4=−4
Step 3: Subtract 4 from both sides.
−6x+4−4=−4−4
−6x=−8
Step 4: Divide both sides by -6.
-6x/-6 = -8/-6
x = 4/3
so, the other answer is wrong because she did not multiply the numbers in the parenthesis correctly

The balance after the grace period is $25,000. A payment of $5,000 is made on the 10th day. A payment of $5,000 is made on the 20th day. What is the average daily balance?
The average daily balance after 20 days is; $1750
Average BalanceThe initial balance after grace period is; $25,000
Afterwards, A payment of $5,000 each is made on the 10th and 20th day.
Hence, the total balance after 20 days is;
= $25,000 + $5000 + $5000= $35,000.The average daily balance is therefore the quotient of $35,000 and 20 days

a) x = 1 ± 3i / 2
b) x = 1 ± √11 / 5
c) x = 1 ± i √29 / 5
Answer:
c) x = 1 ± i √29 / 5
Step-by-step explanation:
assuming we are solving for x we can use the quadratic formula
quadratic formula : [tex]\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}[/tex]
where the values of a,b and c are derived from the equation
the equation is put in quadratic form : ax² + bx + c
so in 5x² -2x + 6 a = 5 , b = - 2 and c = 6
we then plug these values of a, b and c into the quadratic formula
recall quadratic formula [tex]\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}[/tex]
a = 5 , b = - 2 , c = 6
[tex]\frac{-(-2)+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}[/tex]
remove parenthesis at -(-2) to get positive 2 because the negative signs cancel out
[tex]\frac{2+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}[/tex]
evaluate exponent
[tex]\frac{2+or-\sqrt{4-4(5)(6)} }{2(5)}[/tex]
multiply -4(5)(6)
[tex]\frac{2+or-\sqrt{4-120} }{2(5)}[/tex]
subtract 120 from 4
[tex]\frac{2+or-\sqrt{-116} }{2(5)}[/tex]
multiply 2 and 5
[tex]\frac{2+or-\sqrt{-116} }{10}[/tex]
because we cant have a negative square root we replace the negative sign with i (which equals -1 ) and add it to the outside of the square root
[tex]\frac{2+or-i\sqrt{116} }{10}[/tex]
we then simplify the radical
[tex]\frac{2+or-2i\sqrt{29} }{10}[/tex]
we then simplify the fraction
2/10 = 1/5 so both 2's cancel out
[tex]\frac{1+or-i\sqrt{29} }{10}[/tex]
the answer is C

1) On a map, the key indicates that 2.5 centimeters equal 10 miles. A
road on the map runs for 30 centimeters. How long is the road?
Answer:
120 miles
Step-by-step explanation:
A proportion is a ratio that equals a ratio. I'm going to use cm/miles when I setup the proportion.
[tex]\frac{2.5}{10} =\frac{30}{x}[/tex]
Cross multiply
2.5x = 300

If each side of a square grows 6 mm, the area of the square is multiplied by 16. How long are the sides of the original square?
Answer:
2 mm
Step-by-step explanation:
Let x be the sides of the original square,
then the area of the original square is x^2
The sides of the new square is x + 6
The area is (x + 6)^2
Then (x + 6)^2 = 16*x^2
Take square root on both sides and get
x + 6 = 4x,
3x = 6
so x = 2 mm
Does the point (-2,-3) lie in the graph of y>2x+1?

A line passes through the point (-9,-4) and has a slope of -2/3 . write an equation in slope intercept form for this line
Answer:
[tex]y=-0.667x+-10[/tex]
Step-by-step explanation:
Given the following question:
Point A = (-9, -4), (x1, y1)
Point B = (-6, -6), (x2, y2)
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6--4}{-6--9} =\frac{-2}{3}[/tex]
[tex]m=\frac{-2}{3}[/tex]
Write in slope intercept form:
[tex]y=mx+b[/tex]
[tex]m=\frac{-2}{3}=-2\div3=-0.667[/tex]
[tex]y=-4[/tex]
[tex]x=-9[/tex]
[tex]-4=-0.667\times-9+b[/tex]
[tex]-0.667\times-9=6[/tex]
[tex]b=-10[/tex]
[tex]y=-0.667x+-10[/tex]

Write the equations of the lines described.
The line has a slope of 1/5 and y-intercept of (0, -4)
Answer:
y=1/5x-4
Step-by-step explanation:
Hi there!
We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)
There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We are already given the slope (1/5), so we can plug it in as m in the equation.
y=1/5x+b
Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept
In this case, b would equal -4
So substitute -4 as b into the equation:
y=1/5x-4
This is the equation of the line.
Hope this helps!

1/3(z+1/5)=-2/5 what’s z?
Answer:
(exact form) z= -7/5
or
(decimal form) z= -1.4
or
(mixed number form) z= -12/5
Step-by-step explanation:
Answer:
The value of z is -7/5
Step-by-step explanation:
1/3 (z + 1/5) = -2/5
z/3 + 1/5 × 3 = -2/5
z/3 + 1/15 = -2/5
15z + 3/45 = -2/5
15z + 3 = -2(45) ÷ 5
15z + 3 = -2(9)
15z + 3 = -18
15z = -18 – 3
15z = -21
z = -21/15
z = -7/5
Thus, The value of z is -7/5

Find the area of the composite figure.
Answer:
104 m²
Step-by-step explanation:
From inspection of the diagram, we can see that the composite figure is made up of a triangle and a rectangle.
Triangle
If you turn the figure 90° clockwise, you will see that the base of the triangle = 8m and the height of the triangle = 6m.
Area of a triangle = 1/2 x base x height
⇒ area of the triangle = 1/2 x 8 x 6 = 24 m²
Rectangle
From inspection, the length of the rectangle = 10m and the width = 8m
Area of a rectangle = length x width
⇒ area of the rectangle = 10 x 8 = 80 m²
Composite figure area
Therefore the total area of the figure = area of triangle + area of rectangle
⇒ total area = 24 + 80 = 104 m²
Answer:
104 m^2
