Describe the first step you would take in solving 12 = 7 - 3x + 5x. Explain.
Answer:
the first step would be to combine the x's
Step-by-step explanation:
1.) combine x (12=7+2x)
2.) subtract 7 from both sides of the equation (5=2x)
3.) divide by 2 to allow x to be by its self (5/2=x)

Passes through (2, 3) at a gradient of 2
Answer:
y = 2x-1
Step-by-step explanation:
I'm guessing gradient of 2 means slope of 2
if line passes through (2,3) and has a slope of 2, we can use the slope intercept equation
slope-intercept (y=mx+b)
m is the slope and b is the y-intercept (which we are trying to find)
so far, we have a point and a slope so we can fill in x,y, and m
(3) = (2)(2) + b
3 = 4 + b
3-4 = 4-4 + b (to undo addition, you use subtraction so I minus 4 from each side)
-1 = b
we found b so we just take the (2,3) out of the equation substitute the x,y back into the equation
y = 2x - 1
What is the output of y= 2/3x −4 when the input is 18?
Answer:
output = 8
Step-by-step explanation:
1. To solve for the output of the equation, we plug in the value of the input, 18, and simplify.
Keep in mind that the input is x, and the output is y.2. (Solving)
[tex]y=\frac{2}{3}(18)-4[/tex] [tex]y = \frac{36}{3}-4[/tex] [tex]y = 12 - 4[/tex] [tex]y = 8[/tex]Therefore, the output is 8.
An equation is formed when two equal expressions. The output of y= 2/3x −4 when the input is 18 is 8.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The output of y= (2/3)x −4 when the input is 18 are,
y = (2/3)x - 4
y = (2/3)18 - 4
y = 12 - 4
y = 8
Hence, the output of y= 2/3x −4 when the input is 18 is 8.

Tell whether the set of ordered pairs {(1, 2), (4, 10), (7, 17), (10, 22)} satisfies a linear function Explain.
Answer is A
No; there is no constant change in x that corresponds to a constant change in y.
Luoa is not easy , I know that for a fact.
The slope of the line is not constant hence it does no satisfies the condition of a straight line therefore non-linear.
What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x,y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
Given a set of ordered pairs {(1, 2), (4, 10), (7, 17), (10, 22)}.
The first pair is y = 2x.
The second pair is 4y = 10x ⇒ y = (10/4)x ⇒ y = (5/2)x.
So, we can conclude that the slope of the line is not constant hence it does no satisfies the condition of a straight line therefore non-linear.

Maria buys n pencils that cost p cents each.
She pays with a $y note.
Find, in terms of n,p and y, the amount of change Maria receives.
Give your answer in cents.
Answer:
change = 100y -np
Step-by-step explanation:
The amount Maria owes for the pencils (in cents) is n times the cost of one pencil: np.
The amount she offers for the pencils (in cents) is 100y, since each dollar is worth 100 cents.
Her change will be the difference between what she offered in payment and what she owes.
change = 100y -np

In a skiing competition. Jen finishes in 13.524 seconds, Ali finishes in 13.51
seconds and Sofia finishes in 13.5 seconds. Who finished first?
Answer:
Sofia at 13.5 seconds
Step-by-step explanation:
These numbers aren't easily compared since they don't have the same number of digits. Sofia's time of 13.5 seconds is less than that of the other two times, 13.524 and 13.51 seconds, but the lack of a zero after the 5 in Sofia's time is concerning. If the other times were measured toi within a hundredth of a second, why not Sofia's time also? Perhps her true time was 13.56 seconds, but the 0.05 was dropped. She would be slower than the other two. But, in the absence of helpful information, the only thing that can be said is that Sofia's time is reported to be less than either Jen and Ali.

In Asha's science experiment, her bacteria are dying at a constant rate of $600$ an hour. If she drew a graph of the number of bacteria in her culture where $x$ represented the time in minutes since the start of the experiment and $y$ represented the number of bacteria remaining in the colony, her graph would be a line. What would be the slope of this line?
Answer:
-10
Step-by-step explanation:
The rate of change is also known as the slope of the function thus the slope will be -600.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.
As per the given,
Bacteria are dying at a constant rate of $600$ an hour.
The rate of change = -600/hour
Slope = y/x = number of bacteria change/time taken
If the graph is a straight line then it will remain constant.
Slope = -600
Hence "The rate of change is also known as the slope of the function thus the slope will be -600".
