Answers
The answer is (x+4)² + y² = 16
x² + y² - 8x = 0
[reorder the terms]
x² - 8x + y² = 0
[to complete the square, add 16 to both sides]
x² - 8x + 16 + y² = 16
[write the expression as a product and 16 as an exponent]
x² - 2 × x × 4 + 4² + y² = 16
[using a² + 2ab + b² = (a + b)², factor the expression]
(x + 4)² + y² = 16
Since this equation can be written as
(x + p)² + (y - q)² = r², it represents a circle.

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?
Answers
Answer:
The numbers are 24, 16 and 48
Step-by-step explanation:
For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.
88=x+(x+8)+3x
Now you simplify the equation,
88=5x+8
Now get the x and it’s coefficient alone on one side
80=5x
Now divide both sides so the x is alone
x=16
Since the second number was x you know the second number
the first number is x+8 since x is 16 the first number is 24
The third number is 3 * x so the third number is 48.
So the numbers are 24, 16 and 48

-4[tex]\leq[/tex]x<3
Step-by-step explanation:
1)Break this into 2 case, equal to 0 and and less than 0.
2)The number equals zero if its numerator is 0 which happens when x=-4.
3) A fraction is less than 0 it is negative. Negative fractions are either +/- or -/+, so we have two subcases.
3a) For +/- the numerator is positive when x>-4 and denominator is negative when x<3. Putting those two together we have -4<x<3.
3b)For -/+ the numerator is negative when x<-4 and the denominator is positive when x>3 however those two values don't overlap.
4) Putting this together we have -4[tex]\leq[/tex]x<3
A machine can blow up 20 balloons in 4 min.
How many balloons can it blow up in 60 min?
Answers
Answer:
120
Step-by-step explanation:
all you have to do is multiply 20*60
Answer:
The machine can blow up 300 balloons in 60 min.
Step-by-step explanation:
60 ÷ 4 = 15. 15 x 20 = 300. We know it takes 4 minutes to blow up 20 balloons. 4 minutes is only 1/15 of 60, so that means you have to blow up 20 balloons 15 times, which will take 60 minutes, and in that 60 minutes, you blew up 300 balloons.

Find intercepts of: 3x-3y+9=0
X-intercept as a ordered pair
Y-intercept as a ordered pairr
Answers
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). It is also the value of y when x = 0.
To solve for the y-intercept, set x = 0:
3(0) - 3y + 9 = 0
3(0) - 3y + 9 = 0
Subtract 9 from both sides:
- 3y + 9 - 9 = 0 - 9
- 3y = -9
Divide both sides by -3 to solve for y:
-3y/-3 = -9/-3
y = 3
Therefore, the y-intercept is (0, 3).
The x-intercept is the point on the graph where it crosses the x-axis, and has coordinates of (a, 0). It is also the value of x when y = 0.
To solve for the x-intercept, set y = 0:
3x - 3(0)+ 9 = 0
3x -0 + 9 = 0
Subtract 9 from both sides:
3x + 9 - 9 = 0 - 9
3x = -9
Divide both sides by 3 to solve for x:
3x/3 = -9/3
x = -3
Therefore, the x-intercept is (-3,0).
The correct answers are:
Y-intercept = (0, 3)
X-intercept = (-3, 0)

Find the magnitude of the vector (4, - 4).

Answers
Answer:
the magnitude of the vector is given by the √(px^2+py^2) so the value is 5.65
The magnitude of the given vector (4, -4) in the simplified form will be 5.65.
What is a Vector?A vector is a quantity with both magnitude and direction in physics. It is often depicted by an arrow with the same direction as the amount and a length proportionate to the size of the quantity.
A vector lacks position, but has magnitude and direction. A vector is therefore unaffected by displacement parallel to itself as far as its length is unaltered.
As per the given data in the question,
4² + (-4)² = 16 + 16
= 32

Hey can anyone help with this question please and thank you
Answers
Answer:
(7x-4)°= (3x+28)°. ( :. m || n, so it is alternate angle)
7x° - 4° = 3x° + 28°
4x° = 32°
x = 32/8
x = 4°
Answer:
x = 8
Step-by-step explanation:
< (7x - 4)° and < (3x + 28)° are Alternate interior angles that do not have a common vertex on alternate sides of the transversal, t. Therefore, they have the same measure.
We can establish the following equality statement to solve for x :
< (7x - 4)° = < (3x + 28)°
Subtract 3x from both sides:
7x -3x - 4 = 3x - 3x + 28
4x - 4 = 28
Add 4 to both sides:
4x - 4 + 4 = 28 + 4
4x = 32
Divide both sides by 4 to solve for x:
4x/4 = 32/4
x = 8.
To verify whether the value of x is correct, substitute x = 8 into the equality statement:
< (7x - 4)° = < (3x + 28)°
< [(7(8) - 4]° = < [3(8) + 28]°
< (56 - 4)° = < (24 + 28)°
< 52° = < 52° (True statement. Therefore, the correct answer is x = 8).

Find: 11/3 divided by 2/3
The quotient is 5 and ______
Answers
Answer:
1/2
Step-by-step explanation:
11/3 divided by 2/3
=5.5
11/3 divided by 2/3 , the quotient is 5 and remainder is 1.
The divisor is the integer that divides a given number. The resultant number is sometimes referred to as the quotient. The residual is the number that the divisor leaves after partially dividing the original integer.
Let, first number is x and second number is y
On dividing given two number
Division=x/y
[tex]x/y=\frac{11/3}{2/3}[/tex]
[tex]x/y=11/2[/tex]
It is given that the quotient for dividing two numbers is 5.
Using,
Dividend = Divisor x Quotient + Remainder
Here,
Dividend =11
Divisor =2
Quotient =5
On, substituting these values to get Remainder
11=2 x 5+ Remainder
Remainder=1
Thus, remainder is 1.

We must do rise over run to find the slope.
First find 2 points that cross the corner of the grid as shown in the attached image.
Then count how many units up and over it takes to connect the 2 points. For this example, there are 3 up and 4 across.
ΔX = 0 – -4 = 4

First make an equation for both rules.
Rule 1: y=5x
Rule 2: y= x+12
Then plug in each ordered pot to find which one works
Choice A (5,25)
Rule 1: 25=5(5)
25=25
Rule 2: 25=5+12
25=17
Choice a works for rule 1 but not rule 2 therefore it does not work
Choice b (3,15)
Rule1: 15=3(5)
15=15
Rule 2: 15=12+3
15=15
Choice be works works for both equations therefore it is the answer
Choice c (0,12)
Rule 1: 12=5(0)
12=0
Rule 2: 12=12+0
12=12
Choice c works for rule 2 but not 1 do it cannot be the answer.
