Answer:
y = [tex]\frac{x}{4}[/tex] - 2
Step-by-step explanation:
y - 1 = 1/4 (x - 12)
y - 1 = 1/4 (x) -3
y = 1/4 (x) -3 +1
y = [tex]\frac{x}{4}[/tex] - 2

[tex]\\ \rm\Rrightarrow y^2=108[/tex]
[tex]\\ \rm\Rrightarrow y=6\sqrt{3}[/tex]
Answer:
6√3 units
Step-by-step explanation:
Similar right triangle theorem states that as ΔNUT ≅ ΔTUM then
NT : NU = TM : TU
First find the length of TU using Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ UM² + TU² = TM²
⇒ 3² + TU² = 6²
⇒ TU² = 27
⇒ TU = √(27)
⇒ TU = 3√3
Given:
NT = yNU = 9TM = 6TU = 3√3NT : NU = TM : TU
⇒ y : 9 = 6 : 3√3
[tex]\implies \dfrac{y}{9}=\dfrac{6}{3\sqrt{3} }[/tex]
[tex]\implies (3\sqrt{3})y=6 \times 9[/tex]
[tex]\implies y=\dfrac{54}{3\sqrt{3}}[/tex]
[tex]\implies y=6\sqrt{3}[/tex]

<MPN = ?°
Answer:
45°
Step-by-step explanation:
The triangles CPN and APM are isosceles, which gives rise to angle relationships that can be used to find the desired angle.
Let the angle at A be represented by α. Then the angle at C is the complementary angle (90° -α). The angles MPA and NPC are, respectively ...
∠MPA = (180° -α)/2 = 90° -(α/2) . . . . . . . base angle of ΔAPM
∠NPC = (180° -(90° -α))/2 = 45° +α/2 . . . base angle of ΔCPN
The sum of angles MPA, MPN, NPA is the linear angle APC, so we have ...
∠MPA +∠MPN +∠NPA = 180°
(90° -α/2) +∠MPN +(45° +α/2) = 180°
135° +∠MPN = 180°
∠MPN = 45°

The area of a rectangle is 32 inches squared. If the length is 8 inches, what is the *perimeter* of the rectangle?
Answer:
Step-by-step explanation:
w (width) = 32/8

p (perimeter) = 2w + 2l
p = (2 x 4) + (2 x 8)
p = 8 + 16
p = 24

express x^2-8x+5 in the form (x-a)^2-b where a and b are intergers
Answer:
(x - 4)^2 - 11
Step-by-step explanation:
Here, the question asks you to complete the square. The steps to do so are the following:
ax^2 + bx + c = a(x - b/2 x)^2 -(b/2)^2 + c
1. halve the x coefficient and put it with x as a binomial squared
2. minus the new coefficient squared
3. collect like terms
so let's do it for this question:
x^2 - 8x + 5
step 1:
half of -8, is -4, so we'll get:
= (x - 4)^2 + 5
However this isn't equal to x^2 - 8x + 5, but to x^2 - 8x + 16 + 5. Therefore we must get rid of 16 (step 2). You will notice 16 = (-4)^2 (from the first formula I gave.)
= (x - 4)^2 - 16 + 5
step 3:
= (x - 4)^2 - 11
Answer:
(x - 4)² - 11
Step-by-step explanation:
x² - 8x + 5
using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11
What volume of silver metal will weigh exactly 2500 grams? The density of silver metal is 10.5 g/cm^3
The volume of silver metal that will weigh exactly 2500 grams having a density of 10.5g/cm3 is 238.1cm3
What is density?Density is the ratio of the mass of a substance to its volume.
Analysis:
Density = 10.5g/cm3 = mass/volume
10.5 = 2500/volume
volume = 2500/10.5 = 238.1g/cm3
In conclusion, the volume of silver metal to weigh exactly 2500grams is 238.1cm3

Jenna bought a savings certificate that earned 2% simple interest per year. She earned a total of $100 in interest over 4 years. What was the initial value of the certificate?
Answer: Below
Step-by-step explanation:
An interesting part of this problem is that it derives off of Exponential growth formulas.
So by plugging in the values in the Exponential growth:
[tex]y = x(1+0.02)^{4}[/tex]
[tex]y = x(1.02)^{4}[/tex]
What's important is we know the increasing factor, so:
[tex](1.02)^{4} = 1.0824[/tex]
So now we know 8.24% of something is equal to 100. We can use this to find x, which is our initial value.
x * 0.0824 = 100
x = 100/0.0824
x = 1213.59
The answer is approximately 1213.59

How do you find the slope of a line when you are given 2 points?
Answer: Since the slope of a line is the change in y divided by the change in x, given two points (x1,y1) and (x2,y2) we can find the slope by calculating (y2-y1)/(x2-x1).
Answer:
Use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

~Amphitrite1040:)
Answer:
2/3x + 5=1
To solve for x, we must isolate it by administering inverse operations.
In this equation, we can see 2/3x is being added to 5.
We should discard the constants first.
The inverse operation of addition, is subtraction.
So we subtract 5 from both sides;
-5 -5
2/3x = -4
Now, we are left with a coefficient, so to get rid of the coefficient we utilize the inverse operation of multiplication, which is division.
Dividing by 2/3 is the same as multiplying by 3/2.
So multiply both sides by 3/2;
*3/2 *3/2
x = -4(3)/2
x = -12/2
x = -6
