7. The perimeter of a rectangular pool is 70 meters. If the width of the pool
is 12 meters, then find its length.
Answer:
23 meters
Step-by-step explanation:
You would subtract 24 from 70, and then divide by two.
70-24=46
46/2 = 23
How do you show that x=6 is an true equation ?
x = 6 can be represented on the number line and hence it is real
Step-by-step explanation:
by simply plugging in 6 for x thus
x=6 becomes 6=6 which is true

What is the equation of the line on the graph? Write your answer in slope-intercept form. (y = mx + b)
Don't forget to simply if you can!
Answer:
y= ⅔x -2
Step-by-step explanation:
slope-intercept form
y= mx +b, where m is the slope and b is the y-intercept.
Two given coordinates: (-3, -4) and (6, 2)
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
Slope
[tex] = \frac{2 - ( - 4)}{6 - ( - 3)} [/tex]
[tex] = \frac{2 + 4}{6 + 3} [/tex]
[tex] = \frac{6}{9} [/tex]
[tex] = \frac{2}{3} [/tex]
Substitute m= ⅔ into the equation:
y= ⅔x +b
From the graph, the y- intercept is -2 since the line cuts through the x-axis at (0, -2).
Alternatively, we can also substitute a pair of coordinates into the equation to find the value of b.
When x= 6, y= 2,
[tex]2 = \frac{2}{3} (6) + b[/tex]
2= 4 +b
b= 2 -4
b= -2
Thus the equation of the line is y= ⅔x -2.
Leonardo da Vinci's portrait the Mona Lisa is
2 feet 6 inches long and 1 ft 9 inches wide.
Janelle has a refrigerator magnet of the
painting that is 3.5 cm wide. What is the
length of the magnet?
Answer:
the length of the magnet is 5cm
Step-by-step explanation:
first convert the feet into inches: 2ft 6in=30in, 1ft 9in=21in
then convert inches into centimeters (times by 2.5): 30*2.5=75cm 21*2.5=52.5
then divide 52.5 by 3.5 to get a proportion: 52.5/3.5=15
then divide 75 by 15: 75/15=5cm

Find the perimeter of an isosceles triangle. The base is 3y and each side is (0.6y-7).
Answer:
Perimeter = 4.2y - 14
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sided of the triangle.
In an isosceles triangle, there are two equal sides and a base.
Perimeter = (0.6y - 7) + (0.6y - 7) + 3y
Perimeter = (0.6y + 0.6y + 3y) - 7 - 7
Perimeter = 1.2y + 3y - 14
Perimeter = 4.2y - 14

Answer:
Step-by-step explanation:
2x-y=4 ..........(1)
x+y=5 ...........(2)
Add equation 1 and 2:
We get:
3x=9
x=9/3
x=3
Substitute value of x in (2):
x+y=5
3+y=5
y=5-3
y=2

find vertex and min/max !! HELP ASAP!!
y=-2(x+9)(x+3)
Answer:
max at (- 6, 18 )
Step-by-step explanation:
Given the equation of a parabola in intercept form
y = a(x + c)(x + d)
• If a > 0 then min vertex
• If a < 0 then max vertex
y = - 2(x + 9)(x + 3) ← is in intercept form
with a = - 2 < 0 then max vertex
y = - 2(x + 9)(x + 3) ← expand factors using FOIL
= - 2(x² + 12x + 27) ← distribute parenthesis by - 2
y = - 2x² - 24x - 54 ← in standard form
with a = - 2 and b = - 24
The x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex] = - [tex]\frac{-24}{-4}[/tex] = - 6
Substitute x = - 6 into the equation and evaluate for y
y = - 2(- 6 + 9)(- 6 + 3) = - 2(3)(- 3) = 18
vertex = (- 6, 18 ) and is a max
Find the values of m for which the equation
x^2 +2mx + 9 = 0 has no real roots
Answer:
Interval notation for m: (-3,3)
Inequality notation: -3<m<3
In words: Anything between -3 and 3 without including either -3 or 3.
Step-by-step explanation:
If we want no real roots then b^2-4ac must be less than 0.
a=1
b=2m
c=9
These values were found by comparing your equation to ax^2+bx+c=0.
b^2-4ac<0 is what we are trying to satisfy
(2m)^2-4(1)(9)<0
4m^2-36<0
Divide both sides by 4:
m^2-9<0
Add 9 on both sides:
m^2<9
m^2<9 when m<3 and m>-3.
Interval notation (-3,3).
140 grams of almonds cost $3.5. Mechael needs almonds for the dish she is preparing. How much she has to pay for 500 grams of almonds cost?
Answer:
$12.5
Step-by-step explanation:
140 divided by 7 is 20, since 20 is a factor of 500, it will make it easier. Since we divided the 140 grams by 7, we also have to divide the $3.5 by 7, which will get you$0.5. 20 times 25 is 500, so you will also time the $0.5 by 25 which will get you $12.5

Z is the centroid of AUVW. U X Z W Y What is UY if UZ = 8? Ο Α. 4 B. 8 O C. 6 O D. 12
Help Please!!
Answer:
D
Step-by-step explanation:
The distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is
ZY = [tex]\frac{1}{2}[/tex] UZ = [tex]\frac{1}{2}[/tex] × 8 = 4
Then
UY = UZ + ZY = 8 + 4 = 12 → D

Determine the value of x.
Answer:
x = 16
Step-by-step explanation:
46° and (3x - 2)° are alternate angles and are congruent , so
3x - 2 = 46 ( add 2 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16
Help please I really don’t understand due in 3 days
Answer:
x < 4
Step-by-step explanation:
3x - 3 < 9 ( add 3 to both sides )
3x < 12 ( divide both sides by 3 )
x < 4
Answer:
x < 4.
Step-by-step explanation:
3x - 3 < 9
Add 3 to both sides:
3x < 9 + 3
3x < 12
Divide both sides by 3:
x < 4.
