Answer:
y=5
Step-by-step explanation:
Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y=1/2x-2
Step-by-step explanation:
2y=-4+x
2y=x-4 divide both sides by 2
y=1/2x-4/2
y=1/2x-2
Answer:
[tex]y = 0.5x - 2[/tex]
Step-by-step explanation:
Slope intercept form is
[tex]y = mx + b[/tex]
Our initial goal is to isolate y.
[tex]2y - x = -4[/tex]
Add x to both sides of the equation.
[tex](2y - x) + x = (-4) + x[/tex]
Simplify.
[tex]2y =x -4[/tex]
Divide both sides by 2.
[tex]\frac{2y }{2} = \frac{(x - 4)}2}[/tex]
Simplify.
[tex]y = 0.5x - 2[/tex]

Can you help me, please?
Answer:
a. 18
b.144
c.108
Step-by-step explanation:
Using the given, Angle R equal 5x-54 and Angle T is 8u.
Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.
However, we can add , interior angle T, and STU to 180 to find x.
Interior angle T=SRT so interior angle t=5x-54.
Set up equation
[tex]5x - 54 + 8x = 180[/tex]
[tex]13x - 54 = 180[/tex]
[tex]13x = 234[/tex]
[tex]x = 18[/tex]
b.Plug 18 into 8x
[tex]8(18) = 144[/tex]
STU=144
c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.
Angle S and Angle R are the non adjacent angle to STU.
So we cast up this equation.
[tex]5x - 54 + s = 180[/tex]
plug 18 in for x
[tex]5(18) - 54 + s = 144[/tex]
[tex]90 - 54 + s = 144[/tex]
[tex]36 + s = 144[/tex]
s=108
A cylinder shaped water tank has a diameter of 8 m and a height of 20 m.
What volume of water does the tank contain when it is 60% full?
Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.
___ m3
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.

e=

g=

h=
⇒ -2.5
i=
⇒ 3.5
Step-by-step explanation:
The values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.
What is the matrix?It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.
We have a matrix A shown in the picture:
| 2 3 3 |
A = | 3 1 2 |
| 7 8 9 |
It is required to find the inverses of a matrix.
To find the inverse of a matrix:
Augment with a 3x3 identity matrix
[tex]=\begin{bmatrix}2&3&3&\mid \:&1&0&0\\ 3&1&2&\mid \:&0&1&0\\ 7&8&9&\mid \:&0&0&1\end{bmatrix}[/tex]
Convert the matrix to the identity matrix.
[tex]=\begin{bmatrix}1&0&0&\mid \:&\frac{7}{2}&\frac{3}{2}&-\frac{3}{2}\\ 0&1&0&\mid \:&\frac{13}{2}&\frac{3}{2}&-\frac{5}{2}\\ 0&0&1&\mid \:&-\frac{17}{2}&-\frac{5}{2}&\frac{7}{2}\end{bmatrix}[/tex]
Simply it:
[tex]=\begin{pmatrix}\dfrac{7}{2}&\dfrac{3}{2}&-\dfrac{3}{2}\\ \dfrac{13}{2}&\dfrac{3}{2}&-\dfrac{5}{2}\\ -\dfrac{17}{2}&-\dfrac{5}{2}&\dfrac{7}{2}\end{pmatrix}[/tex]
From the inverse matrix the values of unknows can be find:
a = 7/2
b = 3/2
c = -3/2
d = 13/2
e = 3/2
f = -5/2
g = -17/2
h = -5/2
i = 7/2
Thus, the values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.

Simplify the expression
8.8 (3.6d +1)
Answer:
31.68d + 8.8
Step-by-step explanation:
We have to simplify the expression but with one dillemma. The number 8.8 is outside the parenthesis of 3.6d + 1 and 3.6d + 1 aren't combinable because they aren't like terms.
When we have a problem like 8.8 being out of the parenthesis, we need to distribute 8.8 to both numbers in the parenthesis, or in other terms multiplying.
(8.8 * 3.6d + 1 * 8.8)
31.68d + 8.8

Answer:
1.25 × 10^-4
Step-by-step explanation:
Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4

I'm having trouble solving the system of linear equations. This is the system: 5x + 6y = 50 x - 6y = -26 Can you please help me? Don't give the answer, but can you just explain?
Answer:
y = 5 ; x = 4
Step-by-step explanation:
Given :
5x + 6y = 50 - - - (1)
x - 6y = -26 - - - (2)
From (2)
x = - 26 + 6y
Put - 26 + 6y for x in (1)
5(-26 + 6y) + 6y = 50
-130 + 30y + 6y = 50
-130 + 36y = 50
-130 - 50 = - 36y
-180 = - 36y
y = 180 / 36
y = 5
Put y =5 in x = - 26 + 6y
x = - 26 + 6(5)
x = - 26 + 30
x = 4
y = 5 ; x = 4

Consider the sequence 1, –3, 9, –27, 81, … Which statement describes the sequence?
The sequence diverges.
The sequence converges to 0.
The sequence converges to 1.
The sequence converges to ∞.
Answer:
There is a similar problem with the same numbers except with no negatives so it goes 1 , 3 , 9 , 27, 81 for this question the answer is that it diverges.
Step-by-step explanation:
It was on the unit test review for edge and the answer was that it diverges.
This is about understanding the behavior limits of sequence.
The sequence diverges.
The given sequence is;1, –3, 9, –27, 81,...
Now, from the sequence above, we can see that each number is multiplied by -3 to get the next one in the sequence. From mathematical definition, A divergent sequence is one in which the values are approaching an infinite value which could either be positive or negative whereas if it is a convergent sequence it will be approaching 0. In this sequence given, we can see that the values are increasing to either positive or negative and as such it will keep changing till an infinite positive or negative value which corresponds with the definition of a divergent sequence as earlier defined.• Thus, the sequence is a divergent one.

a car completes a 200km journey at an average speed of xkm/h. the car completes the return journey of 200 km at an average speed of (x+10)km/h. show that the difference of the time taken for each of the two journeys is 2000/x(x+10) hours
Answer:
The difference of the time taken for each of the two journeys is given as follows;
The difference of time = 2000/(x·(x + 10))
Step-by-step explanation:
The speed with which the car completes the 200 km journey = x km/h
The speed with which the car completes the return journey = (x + 10) km/h
Let t₁ represent the time it takes the car to complete the 200 km and let t₂ represent the time it takes the car to complete the return journey, we have;
t₁ = 200/(x)
t₂ = 200/(x + 10)
The difference of the time taken for each of the two journeys = t₁ - t₂
We have;
t₁ - t₂ = 200/(x) - 200/(x + 10)
200/(x) - 200/(x + 10) = (200·(x + 10) - 200·x)/((x)·(x + 10)) = 2000/((x)·(x + 10))
∴ t₁ - t₂ = 2000/((x)·(x + 10)) = 2000/(x·(x + 10))
The difference of the time taken for each of the two journeys = t₁ - t₂ = 2000/(x·(x + 10))
