180=x+(3x-8)
Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884

Step-by-step explanation:
Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 8 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
150 minutes
160 minutes
170 minutes
180 minutes
Answer: b. 160
Step-by-step explanation: just took the test
There are 160 minutes would the water level be less than or equal to 64 cups.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Here, The equation we're given is,
W = -0.414t + 129.549,
which an be written as,
-0.414t + 129.549 = W.
Now, We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.
Plugging this information in, we have:
-0.414t + 129.549 ≤ 64
To solve this, we first cancel 129.549 by subtracting from both sides:
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Now divide both sides by -0.414:
-0.414t/-0.414 ≤ -65.549/-0.414
t ≥ 158.33
(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)
t ≥ 160 minutes
Thus, There are 160 minutes would the water level be less than or equal to 64 cups.

Answer:
The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]
Step-by-step explanation:
We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line [tex]y=-\frac{1}{3}x+4[/tex]
The general form of point-slope is; [tex]y-y_1=m(x-x_1)[/tex]
where m is slope and [tex](x_1,y_1)[/tex] is the point
We need to calculate slope.
We are given equation of line [tex]y=-\frac{1}{3}x+4[/tex] that is perpendicular to the required line.
The equation is given in slope-intercept form [tex]y=mx+b[/tex] where m is slope.
Comparing both equations we get m= -1/3
But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e [tex]m=-\frac{1}{m}[/tex]
So, slope of required line is m = 3 (opposite reciprocal of -1/3)
Now, the equation in point-slope form having slope m=3 and point (6,-5) is
[tex]y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)[/tex]
So, The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]

Answer:
x = 2
Step-by-step explanation:
x/6 + 1 = 2x - 8/3 (first you want to multiply by 6 on both sides to get rid of x/6)
x + 6 = 12x - 16 (add 16 on both sides)
x + 22 = 12x (subtract x on both sides)
22 = 11x (divide by 11 on both sides)
2 = x

The graph represents f(x) = x +3
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

Answer:

Step-by-step explanation:
edge 2020 :) have a nice day
The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).
The given function is f(x)=x+3.
To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.
From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.
To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.
Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.
So, f(-2.2) = −1 + 2
f(-2.2) = 1.
Thus, the required value of f(-2.2) is 1.

1. Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with
the origin as the center of dilation using the rule (x, y) - (x, y) to create pentagon
M'N'P'Q'R'. Which statement is true?
Answer:
B
Step-by-step explanation:
if its less than 1 it shrinks
The correct statement is; Pentagon M’N’P’Q’R is smaller than pentagon MNPQR because the scale factor is smaller than 1.
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
If a polygon is dilated by a scale factor = k
Rule to be followed as;
(x, y) → (kx, ky)
Here, k = Scale factor
If 0 < k < 1, size of the image will be reduced.
Similarly, k > 1, size of the image will be enlarged.
We are given that Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.
Rule used for the transformation,
(x, y) → (1/4x, 1/4y)
Here, the scale factor through which MNPQR has been dilated is 1/4.
Since, scale factor is between zero and 1/4, size of M'N'P'Q'R' will be reduced.
Therefore, the size of pentagon M'N'P'Q'R' will be 1/4 smaller than pentagon MNPQR.

Which answer choice do I pick?
Answer:
D. f(x) = 8x
Step-by-step explanation:
At each increasing x point, the y point increases by 8, this means that for each x increasing by 1, y increases by 8, which means y = 8x
Answer:
Fourth choice, f(x) = 8x
Step-by-step explanation:
y is going up or down and x is left or right, u riht the slope like y/x
so it's going up 8 units every 1 unit it goes to the right so it's 8/1 which is 8 so 8 is ur slope

given a piece wise

A 220-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
The shorter piece is
inches long
Answer:
let x be the length of the shorter piece.
4x + x= 210
x= 42.
4x= 168
The shorter piece is 42in and the long piece is 168 in.
The length of the shorter piece will be;
⇒ x = 44 inch
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
A 220-inch pipe is cut into two pieces.
And, One piece is four times the length of the other.
Now,
Since, One piece is four times the length of the other.
Let height of shorter piece = x
Then, The height of longer piece = 4x
Hence, We can formulate;
⇒ x + 4x = 220
Solve for x as;
⇒ 5x = 220
⇒ x = 220 / 5
⇒ x = 44
Thus, The length of the shorter piece will be;
⇒ x = 44 inch
