Answer:
4x+3=27
Step-by-step explanation:
So there are 4 x so the first part of the 3quation should be 4x then you have 3 so you add three. Your equation should now be 4x+3, and then the sum of all that should equal 27. So therefore the equation is 4x+3=27
Can anyone help me please?

Step-by-step explanation:
what equation represents the line show
Answer:
From looking at the graph, we can already tell it's a negative slope because it's tilting down, so we can eliminate A and D. Where the line intersects the y-axis is the y-intercept or b. Since it intersects at (0,2), the equation should be y=-2x+2.

Answer:
The answer is x = 12
Step-by-step explanation:
So, first you're going to add 8 on both sides
6x - 8 +8 = 5x + 4 + 8
Then simplify
6x = 5x + 12
Then subtract 5x from both sides
6x - 5x = 5x + 12 - 5x
Then simplify again and you get
x = 12

Raul empuja su auto de 950 KG sobre una pista rugosa e inclinada 15,0 con una fuerza paralela a la pista, cuya magnitud es de 200 N. Determina el trabajo mecanico hecho por el peso sobre el auto para un desplazamiento de 5,00m (gravedad=10m/5)
Answer:
966 joules
Step-by-step explanation:
Step one:
given data
mass of car= 950kg
angle of incline= 15°
Applied force= 200N
displacement = 5m
If we apply a force on an object through a distance work is done, hence Mechanical work is the product of a force applied on an object and its displacement while that force is applied
Step two:
Work done= Force * distance
Since the car is moved on an inclined plane, the expression for the work done is
Work-done= Frcos∅
where r is the distance moved
Work-done= 200*5cos 15
Work-done= 200*4.83
Work-done= 966 joules

A line passes through the points (-3, -1) and (-5, 4). What is the slope of this line?
Answer:
y=-2.5x-8.5
Step-by-step explanation:
Please help me due today desperate
Answer:
Slope is 1
Step-by-step explanation:
(-4,-1) (-3,1)
m = y2 - y1 / x2 - x1
Answer:
2
Step-by-step explanation:
Slope is defined as change in y over change in x
if we count, we can tell that the change in y is up 2 boxes for every 1 box you take to the right. We count 1 box right every time so we are always going in the positive direction.
Since slope is change in y over change in x, then you get 2/1 = 2.
I'm having trouble with this question from writing linear equations given two points worksheet by Kuta software can you help? question: (-20, -16), (-1, 18)
Answer:
19y - 34x = 376
Step-by-step explanation:
We are to write the linear equation of a line passing through the points
(-20, -16), (-1, 18)
Using the points slope form of the equation expressed as;
y-y0 = m(x-x0)
m is the slope
(x0,y0) is any point on the line
m = y2-y1/x2-x1
m = 18-(-16)/-1-(-20)
m = 18+16/-1+20
m = 34/19
Substitute the slope m =34/19 and the point (-1, 18) into the expression given
y- 18 =34/19(x-(-1))
19(y-18) = 34(x+1)
19y - 342 = 34x+34
19y-34x = 34+342
19y - 34x = 376
Hence the required equation is 19y - 34x = 376

Hector is decorating a ballroom ceiling with garland. If the rectangular ceiling is 65 meters by
72 meters, how much garland will Hector need to reach from one corner of the ceiling to the
opposite corner?
meters
Submit
Answer:
d = 97 m
Step-by-step explanation:
Given that,
The dimensions of the rectangular ceiling is 65 meters by 72 meters.
We need to find how much garland will Hector need to reach from one corner of the ceiling to the opposite corner. Let it is d. It will be the diagonal of the rectangle. We can find it using Pythagoras theorem as follows :
[tex]d=\sqrt{65^2+72^2} \\\\d=97\ m[/tex]
So, 97 m of garland Hector will needed to reach from one corner of the ceiling to the opposite corner.
The perimeter of a parallelogram is 88 cm and one of its adjacent sides is longer
than the other by 10 cm. Find the length of each of its sides.
Answer:
sides are 17 cm and 27 cm
Step-by-step explanation:
let the side be x then the adjacent side is x + 10
The perimeter is then
x + x + x + 10 + x + 10 = 88, that is
4x + 20 = 88 ( subtract 20 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
and x + 10 = 17 + 10 = 27
The sides of the parallelogram are 17 cm and 27 cm

SAM ≅ ΔZYX ,
Options:
M = 36
M = 60
M = 84
M = 102
Answer:
M = 36
Step-by-step explanation:
Since SAM = ZYX
We can assume that all angles on SAM will equal the same as ZYX.
There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.
Therefore M = 36°

Which of the following pairs are NOT equivalent statements?
In x = y and x = e^y
log⬇️p N = b and b^p = N
x = sqrt y and x = y^1/2
log⬇️b N = p and B^p = N
Answer:
the answer is b
Step-by-step explanation:
bc they are not both equivalent.
The pair (B) is not equivalent after using the property of logarithm option (B) is correct.
What is a logarithm?It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b = c\\log_ac =b[/tex]
It is given that:
The expression is given in the options.
As we know, the expression can be defined as the combination of constants and variables with mathematical operators.
It is required to find the equivalent pairs:
A) In(x) = y and [tex]\rm x = e^y[/tex]
As we know from the log property:
logₙm = a
[tex]\rm \rm n^a = m[/tex]
The pairs are equivalent.
B) [tex]\rm log_p N = b \ and \ b^p = N[/tex]
Again using the log property:
logₙm = a
[tex]\rm \rm n^a = m[/tex]
The pairs are not equivalent.
C) [tex]\rm x = \sqrt y \ and \ x = y^{\dfrac{1}{2}}[/tex]
Using the property of exponent we can write the above expression:
The pairs are equivalent.
D) [tex]\rm log_b N = p \ and \ b^p = N[/tex]
logₙm = a
[tex]\rm \rm n^a = m[/tex]
The pairs are equivalent.
Thus. the pair (B) is not equivalent after using the property of logarithm option (B) is correct.

The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):
A graph with two linear functions; f of x passes through 5, 0 and 10, 10, and g of x passes through negative 3, 0 and 2, 10.
Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)
Part B: Solve for k in each type of transformation. (4 points)
Part C: Write an equation for each type of transformation that can be used to transform f(x) to g(x). (4 points)
Answer:
First, let's find the equations for our lines:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
f(x) passes through (5,0) and (10, 10), then the slope is:
a = (10 - 0)/(10 - 5) = 10/5 = 2.
then we have:
y = 2*x + b
And when x = 5, we have y = 0.
0 = 2*5 + b
0 = 10 + b
b = -10
Then the equation for f(x) is:
y = f(x) = 2*x - 10.
Now for g(x) we have the points:
(3, 0) and (2, 10)
a = (10 - 0)/(2 - 3) = -10
y = -10*x + b
0 = -10*3 + b
b = 30.
y = g(x) = -10*x + 30.
A) Ok, the transformations:
Transformation 1 or T1.
f(x) = 2*x - 10
g(x) = -10*x + 30.
Then, we start with f(x):
First, we can move f(x) up 4 units and get:
f'(x) = 2*X - 6
Now we can dilate f(x) with a scale factor of -5 from the origin, now we get:
f''(x) = -5*f'(x) = -10*x + 30.
And this is g(x).
Transformation 2 or T2.
Move f(x) up 10 units, so now we have:
f'(x) = 2*x
Do a reflection over the x-axis, so the sign of y changes, and now we get:
f''(x) = -2*x
Do a dilation of scale factor 5
f'''(x) = 5*-2*x = -10*x
Now do a vertical translation of 30 units up.
f''''(x) = -10*x + 30 = g(x).
These are two transformations that start with f(x) and end with g(x).
B) Ok, as i was writting the transformations i already solved them, so this part is already done.
C) the equation for the transformations are:
T1) g(x) = -5*(f(x) + 4)
T2) g(x) = -(f(x) + 10)*5 + 30
Rewrite the explicit formula in function form. The identify the y-
intercept of the function.
an = 10+2(n-1)
Answer:
We have the relation:
aₙ = 10 + 2*(n - 1)
And we want to write this in fuction form:
y = f(n)
first we have:
aₙ = y = 10 + 2*(n - 1)
We can rewrite this as:
y = 10 + 2*n - 2
y = 2*n + (10 - 2)
y = 2*n + 8
Now we want to find the y-intercept, this is the value of the function when the variable is equal to zero.
Then if we take n = 0, we get:
y = 2*0 + 8
y = 8
The y-intercept is 8.
