solution set for x = { 4,5,6}
Answer:
2<x<12
Step-by-step explanation:
Firstly, look at this formula-
a-b<x<a+b
If we make 7, A, and 5, B, then the formula would be 7-5<x<7+5
So after you do the math it would be 2<x<12
Hence, the answer is 2<x<12
BTW if the answer is correct then can you please mark me brainlyest?
I'm only 9 years old
Thanks!

Factorize x^2 -9
Answers
Answer:
(x + 3) (x - 3)
Step-by-step explanation:
We know that;
a = 1
b = 0
c = -9
We also know that;
p*q = -9
p + q = 0
In this case, it would make the p value 3, and q value -3
The factorized form would be;
(x + p) (x + q)
=> (x + (3)) (x + (-3))
=> (x + 3) (x - 3)
So therefore, the factorized form;
(x + 3) (x - 3)
Hope this helps!
Answer:
the answer is (x + 3)(x - 3)
Use the given area A of the rectangle to find the value of x . A rectangle with its length labeled left-parenthesis 4 x plus 3 right-parenthesis feet and width labeled left-parenthesis 4 x minus 5 right-parenthesis feet. The area of the rectangle is 209 square feet.
Answers
Answer:
x = 4
Step-by-step explanation:
Length = (4x + 3) feet
Width = (4x - 5 )feet
Area = Length x Breadth
209 = (4x + 3)(4x - 5)
209 = 4x( 4x -5) + 3 (4x -5)
[tex]209 = 16x^2 -20x +12x -15\\\\0 = 16x^2 -8x -15 -209\\\\16x^2 -8x -224 = 0[/tex]
[tex]Quadratic \ Equation \ with a = 16, b = -8, c = -224 \\\\x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}\\\\Substitute \ a, b, c \ in \ the \ equation.\\\\x = \frac{-b + \sqrt{b^2 -4ac}}{2a}, x =\frac{-b \ - \sqrt{b^2 -4ac}}{2a}\\\\x = \frac{8+ \sqrt{64 +14336}}{32}, x = \frac{8- \sqrt{64 +14336}}{32}\\\\x = \frac{8+ \sqrt{14400}}{32}, x = \frac{8-\sqrt{14400}}{32}\\\\x = \frac{8+120 }{32}, x= \frac{8-120}{32}\\\\x = \frac{128}{32} , x = \frac{-112}{32}\\\\x = 4 , x = \frac{-7}{2}[/tex]
Since measure of length or width cannot be negative, we take x = 4

Answers
The Rule for reflection over the y-axis is given by (x,y) to (-x,y).
so, J' (-10,-8)
✐----------------------
hope it helps...
have a great day!
Answer:
J' Coordinates = (-5, -8)
Step-by-step explanation:
We know that in the coordinate point J (5, -8);
x-value = 5
y-value = -8
In order to reflect J over the y-axis, we will keep the y-value of the coordinate same and then reverse the x-value to it's opposite, Therefore the J' coordinates would be;
x-value = -5
y-value = -8
J' Coordinates = (-5, -8)

Bobby mows his neighbors' lawns to raise money to buy a new bike. He charges $5 and then $10 for each hour it takes him to mow the yard. He uses the equation C=5+10h to calculate costs. How many hours does he have to mow for if the bike costs $165?
Answers
Answer:
$16
Step-by-step explanation:
Given data
Flat Charge= $5
Fee per hour= $10
The expression describing the total cost is
C= 5+10h
For C=$165, we can find h as
165=5+10h
165-5=10h
160=10h
h= 16
Hence the cost per hour would be $16

C. The circumference of the circle is 27 π
D. The arc length of the sector is 12π
Answers
Answer:
[tex]\checkmark \text{B. The area of the circle is } 729\pi,\\\checkmark \text{D. The arc length of the sector is } 12\pi[/tex]
Step-by-step explanation:
Area of a circle with radius [tex]r[/tex]: [tex]r^2\pi[/tex]
Circumference of a sector with radius [tex]r[/tex]: [tex]2r\pi[/tex]
Area of sector with angle [tex]\theta[/tex]: [tex]r^2\pi\cdot \frac{\theta}{360}[/tex].
Arc length of sector with angle [tex]\theta[/tex]: [tex]2r\pi\cdot \frac{\theta}{360}[/tex]
Using these equations, we get the following information:
Area of circle: [tex]27^2\pi=729\pi[/tex]
Circumference of a circle: [tex]2\cdot 27\cdot \pi=54\pi[/tex]
Area of sector: [tex]27^2\pi\cdot \frac{80}{360}=162\pi[/tex]

in a bag of keys there are 15 silver keys six black keys 11 copper keys and two painted keys of various colors. one key is drawn what is the probability that the key is silver or copper
Answers
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)

Which graph represents equation (x-4)^2+(y+2)=16
F
H
G
I
Answers
Why is this? Recall that (x-h)^2+(y-k)^2 = r^2 is the general template of a circle. The center being (h,k) and the radius is r.
For the equation (x-4)^2+(y+2)^2 = 16, we have a center of (4,-2) and radius 4. Note that 4^2 = 16.
The graph of choice G shows these properties so that's why it's the answer. Keep in mind that each tickmark represents 2 units. Choice I is close since the center is correct but the radius is too small.

Hello! answer: b = 5
Step-by-step explanation:
13 × 13 = 169 12 × 12 = 144 169 - 144 = 25 5 × 5 = 25 therefore b = 5 hope that helps!
13x13=169
169-144=25
5^2= 25
B=5 feet
∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( 3 x + 25 ) ∘ ∠A=(3x+25) ∘ and m ∠ B = ( 5 x − 7 ) ∘ ∠B=(5x−7) ∘ , then find the measure of ∠ A ∠A.
Answers
Answer:
52º
Step-by-step explanation:
Complementary angles are a set of angles that add up to 90º. Knowing this, we can find the value of x by setting the sum of these two angles equal to 90. For example:
3x + 25 + 5x - 7 = 90
8x + 18 = 90
8x = 72
x = 9
Now that we know our x value, we can find the measure of angle A. Simply plug in the value of x to the measurement of angle A, which is 3x + 25.
3(9) + 25 = 52º
