Determine the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1) by following the steps below. Use the distance formula to determine the radius: d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot Substitute the known values into the standard form: (x – h)² + (y – k)² = r². What is the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1)? x2 + (y + 4)² = StartRoot 5 EndRoot (x – 1)² + (y + 2)² = 5 (x + 4)² + y² = 5 (x + 2)² + (y – 1)² = StartRoot 5 EndRoot
Answer:
Radius length: √5
Standard Form (Equation): (x + 4)^2 + y^2 = 5
Step-by-step explanation:
First we will determine the radius;
Center: (-4, 0)
Point on Circumference: (-2, 1)
d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2
= √4 + 1 = √5
Therefore the radius is of length √5
Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.
Answer:
its C. (x + 4)² + y² = 5

Factorise the expression 6x^2-13x+6 and hence solve the equation 6x^2-13x+6=0
Answer:
Part A
The factored form of the expression, 6·x² - 13·x + 6 is (2·x - 3) × (3·x - 2)
Part B
The solution of the equation 6·x² - 13·x + 6 = 0 are x = 3/2 or x = 2/3
Step-by-step explanation:
Part A
The given expression to factorize is 6·x² - 13·x + 6, which can be written as follows;
6·x² - 13·x + 6 = 6·x² - 4·x - 9·x + 6
The 13·x is split at - 4·x - 9·x
6·x² - 4·x - 9·x + 6
2·x·(3·x -2) - 3·(3·x - 2)
Bringing out the common factor (3·x - 2) gives;
(2·x - 3) × (3·x - 2)
Therefore, the expression 6·x² - 13·x + 6 in factored form is (2·x - 3) × (3·x - 2)
Part B
Solving the equation, 6·x² - 13·x + 6 = 0, therefore gives;
6·x² - 13·x + 6 = (2·x - 3) × (3·x - 2) = 0
Therefore, either (2·x - 3) = 0 and x = 3/2 or (3·x - 2) = 0 and x = 2/3
From which we have 6·x² - 13·x + 6 = 0 when x = 3/2 or 2/3 and x = 3/2 or x = 2/3 are the solution of the equation 6·x² - 13·x + 6 = 0.

Can anyone help me with this for some reason I can’t get my head round it
Answer:
4116
Step-by-step explanation:
12000÷100=120 2015
120×70=8400
8400÷100=84 2016
84×70=5880
5880÷100=58.8 2017
58.8×70=4116
–2.5 + (–3.5)
Which number line shows the sum?
A.
B.
C.
D.
Answer:
The correct answer is C.
Step-by-step explanation:
Because –2.5 + (–3.5) = -6, it means that the red line goes from -6 to -3 1/2 to 0. so that gives us Answer choice C

What value of x makes the equation below true? -26 = 60 + x
Answer:
x = -86
Step-by-step explanation:
60+ (-86)= -26
Answer:
x = -86
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-26 = 60 + x
Step 2: Solve for x
Subtract 60 on both sides: -86 = xRewrite: x = -86Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -26 = 60 - 86Subtract: -26 = -26Here we see that -26 does indeed equal -26.
∴ x = -86 is the solution to the equation.
Question 2
Remember that new marketing gig that Connie landed with Cosmic Coffee? Let's think about the promotion she was
excited to roll out:
Get your made-to-order coffee drink within 3 minutes or it's free!
Recall that it's known from a previous study that the average time it takes for a customer to receive their drink is
2 minutes, 39 seconds, with a standard deviation of 20 seconds.
Part A
Calculate the z-score associated with the value of 3 minutes. Convert 3 minutes and the mean to seconds before doing
the calculation.
9514 1404 393
Answer:
1.05
Step-by-step explanation:
Following instructions, we have ...
Z = (X -μ)/σ
Z = (180 -159)/20 = 21/20
Z = 1.05
The Z-score associated with the value 3 minutes is 1.05.

The order in which we complete an operation is NOT optional. This is because if we do addition or subtraction first, ( which is usually at the end of PEMDAS ) the answer ( even if it looks right ) will always be wrong. Always remember, if you don't do the regular PEMDAS, it will always be wrong.

Evaluate y = 2x + 1 when x= -1
Answer:
y = -1
Step-by-step explanation:
We Know:
y = 2x + 1, and x= -1.
Substitute:
y = 2(-1) + 1
Multiply:
2 * -1 = -2
y = -2 + 1
Add:
-2 + 1 = -1
So,
y = -1.
