Answer:
D. 2x - 6 = 5x - 45
Step-by-step explanation:
To make the linear equation, we can multiply the given equation by 5(x-3).
[tex]\dfrac{x-9}{x-3}=\dfrac{2}{5}\\\\\dfrac{(x-9)(5)(x-3)}{(x-3)}=\dfrac{2(5)(x-3)}{5}\\\\5(x-9)=2(x-3)\qquad\text{looks like }\textit{cross multiply}\\\\5x-45=2x-6\qquad\text{use the distributive property; matches D.}[/tex]
Answer:
The correct answer is D. 2x-6=5x-45

32 = w – 4
1) What is the coefficient?
2) What is the constant?
3) What is the result?
4) What is the variable?
Answer:
1) 1
2.) -4
3.) 32
4.) w
Step-by-step explanation:
Coefficient is the number that is being multiplied by x. W is the same as 1w, so 1 is the coefficient
Constant is the number without any variable that is getting added to the variable (I think that's the definition), and that's -4, because when you subtract a number it's the same as adding it (w+(-4)).
Result is what you're getting, so it is 32, because w-4 equals 32, 32 is the result.
Variable is the unknown value represented by some sort of symbol, which is w, because we don't know w.
W=36

Find an equation of the line containing the given pair of points.
(−5,−5) and (4,4)
Answer:
y = x - 9
Step-by-step explanation:
[tex]Slope=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{4-(-5)}{4-(-5)}=\frac{9}{9}=1[/tex]
[tex]y-intercept:y-y_{1}=m(x-x_{1} ) \\y-(-5)=1(x-4)\\y+5=x-4\\[/tex]
Subtract 5 from both sides;
y = x - 9

A) x<2 Graph A
B) x>2 Graph A
C) x<2 Graph B
D) x>2 Graph B
Answer:
a
Step-by-step explanation:
a
The correct answer for the given inequality 5-x<2(x - 3) + 5 is x<2 Graph A
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, an inequality 5-x<2(x - 3) + 5
On solving, we get,
5-x < 2x-6+5
5-x < 2x-1
5+1 < 3x
x < 2
Let y₁ = 5-x, and y₂ = 2(x - 3) + 5
Plotting the graph, we get the graph A
Hence, the correct answer for the given inequality 5-x<2(x - 3) + 5 is x<2 Graph A

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days. Peter’s Deliveries What is the equation of the line, first written in point-slope form, and then written in slope-intercept form? Show how you determined the equation. Based on the linear model, predict how long it initially took Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences.I need this done before Monday, please!
Answer/Step-by-step explanation:
✍️The equation of the line in point-slope form:
The equation is given as [tex] y - b = m(x - a) [/tex], where,
(a, b) = a point on the line.
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let's find the slope (m) of the line, housing (3, 21) and (6, 12):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3 [/tex]
Substitute a = 3 and b = 21, m = -3 into [tex] y - b = m(x - a) [/tex].
Thus, the point-slope equation would be:
✅[tex] y - 21 = -3(x - 3) [/tex]
✍️The equation of the line in slope-intercept form:
Rewrite [tex] y - 21 = -3(x - 3) [/tex], so that y is made the subject of the formula.
[tex] y - 21 = -3x + 9 [/tex]
Add 21 to both sides
[tex] y = -3x + 9 + 21 [/tex]
[tex] y = -3x + 30 [/tex]
✅The slope-intercept equation of the line is [tex] y = -3x + 30 [/tex]
Where,
-3 = how much did his delivery time decrease per day (slope)
30 = how long it initially took Peter to deliver his packages (y-intercept)

Put the following equation of a line into slope-intercept form, simplifying all
fractions.
8x-6y=6
Answer:
Slope intercept form:
8x-6y=6
You should bring the 8x to the other side of the equal sign.
-6y = 6-8x
Now you need to divide the six to every term to leave the y by itself.
y = 4/3x-1
y = 4/3x-1 IS THE SLOPE INTERCEPT FORM.

A dumpling machine automatically inserts mixed vegetables and meat filled wontons into a plastic package. Past experience revealed that some packages were underweight and some were overweight, but most of them had satisfactory weight.
Weight % of Total
Underweight 2.5
Satisfactory 90.0
Overweight 7.5
Required:
What is the probability of selecting two packages that are satisfactory?
a. 0.900
b. 0.729
c. 0.810
d. 0.075
Answer:
c. 0.810
Step-by-step explanation:
Given, total % of satisfactory packages = 90% = 0.90
Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)
Hence, Probability of selecting two packages that re satisfactory
P(Selecting 2 satisfactory packages) = (0.90)^2
P(Selecting 2 satisfactory packages) = 0.90*0.90
P(Selecting 2 satisfactory packages) = 0.810
Note: We are selecting product since the chance of selecting in each trials are independent.

A rectangle has a width of 10cm. The rectangle length is 4 times its width
Answer:
P = 100 centimeters (assuming you are asking for the perimeter)
Step-by-step explanation:
P = 2 (L + W) OR P = 2L + 2W where P equals the perimeter, L equals the length, and W equals the width.
Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?
P = 2 (L + W)
P = 2 (40 + 10)
P = 80 + 20
P = 100 centimeters

the virus is already 28% loaded if it is loaded at the rate of 12% every 10 minutes how much time do we have before it is 100% loaded .
Answer:
You will have 40 mins before 100%
Step-by-step explanation:
The number of minutes taken to completely load is 60 minutes.
Given that, the virus is already 28% loaded if it is loaded at the rate of 12% every 10 minutes.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here,
Remaining virus to load =100-28
= 72
The rate of 12% every 10 minutes
Now, 72/12
= 6
So, 6×10 =60 minutes
Therefore, the number of minutes taken to completely load is 60 minutes.
