A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
Answer:
2/5
Step-by-step explanation:
first select the line that is positive which is the purple one
slope = change in y / change in x
two clear points are (0,2) and (5,4)
so you do y2-y1 / x2-x1
=(4-2)/(5-0)
=2/5
so the slope is 2/5
does anyone know the answerrr ?

graph the following function on the axes provided.
Answer:
Step-by-step explanation:
The graph of the piecewise function is attached below.
How to graph the following function on the axes provided?Function is a type of relation, or rule, that maps one input to specific single output.
The piecewise function is given as:
f(x) = - 6 for -6< x < 1
-2x + 5 for 1< x < 6
The above means that we plot the function on their interval or domain.
i.e. we plot f(x) = - 6 on the interval x < 0 and f(x) = -2x + 5 on the interval x < -6
Next, we plot the graph of the piecewise function.
Thus, The graph of the piecewise function is attached below.

What is the 50th term of the arithmetic sequence 7, 10, 13, ...?
show complete working format please
Answer:
154
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 10 - 7 = 3 , thus
a₅₀ = 7 + (49 × 3) = 7 + 147 = 154

In the last quarter of a high school football game, your team i s behind by 21 points. A field goal is worth 3 points and a touchdown (after the extra point is worth 7 points. Let x represent the number of field goals scored and y represent the number of touchdowns scored. Write an inequality that models the different number of field goals and touchdowns your team could score to win the game. (Assume the other team doesn't score any more points.)
Answer:
3x + 7y > 21
Step-by-step explanation:
3x + 7y > 21
where:
x = number of field goals needed to win
y = number of touchdowns (plus extra point) needed to win
Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.
Answer:
3x + 7y > 21
3x + 7y > 21
where:
x = number of field goals needed to win
y = number of touchdowns (plus extra point) needed to win
Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.

which step could be used to help isolate the variable in the following equation 5.6j-0.12=4+1.1j
Answer:
Step-by-step explanation:
You did not ask for the answer so I will just tell you the steps. First, you have to add 0.12 on both sides. Then you are going to subtract 1.1j from both sides. Finally you are going to divide both sides by 5.6 to get your final answer.
Answer:
Subtract 1.1j from both sides.

Step-by-step explanation:
On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly
Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
So, total number of questions is 40.

8\2(2+2)
Would it be 1? Or would it be 16? Try it. Correct answer gets brainliest
Answer:16
Step-by-step explanation:
Using PEMDAS:
8 / 2 * (2+2)
Parentheses first: 8 / 2 * (4)
Then go left to right: 8/2 = 4, 4 * 4 = 16.
8/2(2+2)
It will be 16.

7. Of the three explanations below, which person gives the best explanation of why the LSRL is the best line of best fit?
Explain your choice.
Thomas: The LSRL is the best line of
best fit because it touches the most
points on a scatterplot when graphed.
Keene: The LSRL is the best line of best fit
because it has the smallest value for all the
squared residuals added together.
Ella: The LSRL is the best line of best fit because the sum of the residuals is closest to zero when they are all
added together.
Answer:
Ella
Step-by-step explanation:
