Step-by-step explanation:
y-intercept of function f is 1.
What is a function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given function
f(x) = -3x -2 , -∞ < x < -2
= -x + 1, -2 ≤ x < 3
= 2x + 5, 3 ≤ x < ∞
For y-intercept, x =0, f(x) = -x + 1 [∵ -2 < 0 < 3]
f(0) = -0 + 1
= 1
Hence, y-intercept of function f is 1.

Answers
Answer:
Tommy Thomas's tankard holds 160ml when it is one-quarter full.
Step-by-step explanation:
When Tommy's tankard holds 480ml when it's one-quarter empty. There are three other quarters in the tankard. So, you would divide 480 by 3 to see how much is in each of the other 3 quarters. The answer comes down to 160ml per quarter, which equals one-quarter full.

Please help, will award brainliest.
Answers
Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
L₁ is y = 5x + 1 ← in slope- intercept form
with slope m = 5
L₂ is 2y - 10x + 3 = 0 ( subtract - 10x + 3 from both sides )
2y = 10x - 3 ( divide all terms by 2 )
y = 5x - [tex]\frac{3}{2}[/tex] ← in slope- intercept form
with slope m = 5
Since L₁ and L₂ have equal slopes then they are parallel lines

Anna is x years old and her sister, Jane, is y years younger.
How old was Anna when her sister was born?
Answers
========================================================
Explanation:
Let's use numbers in place of the variables
Let's say Anna is 25 years old and her sister Jane is 5 years younger.
This means Anna was 25-5 = 20 years old when Jane was born.
-------------------------
As another example:
Anna = 37 years old
Jane = 10 years younger
Anna was 37-10 = 27 when her sister was born
--------------------------
The examples show that all we do is subtract the x and y values to figure out how old Anna was when her sister was born.
For the first example, we basically did x-y = 25-5 = 20
The second example was x-y = 37-10 = 27
A variable is placeholder for a number. Think of it as a box where a single number will go inside.
Answer:
0+y
Step-by-step explanation:
When Jane was born, Anna was y years old because Jane was 0 years old. That is why the Answer if y or 0+y. But I think the 0+y is more accurate.

Answers
Answer: First, add 3.99 + 7.17. Then take the sum of those two numbers and multiply it by .05 to get 0.55. Since we are dealing money, round to the nearest hundredth to get .56. Add the sum of 3.99 and 7.17 (11.16) and .55 to get a total of 11.71. Therefore the total cost of their dinner, including tax, was $11.71.

f(x) = 3x + 1. Solve for x if f(x) = 19
Answers
3x+1=19
Start by subtracting 1 from each side to start isolating the x.
3x+1=19
-1 -1
————-
3x=18
Next, divide both sides by 3 to completely isolate the x.
3x=18
—- ——
3 3
x=6
Therefore, x for f(x)= 19 is 6
You can check by inserting into the equation 3(6)+1=18+1=19.
Hope this helps!!
Answer:
Step-by-step explanation:
f(x) = 3x + 1
First, we substitute 19 for x :
f(x) = 3(19) + 1
Next we re write the problem and solve for 3 times 19 :
f(x) = 57 + 1
So, the answer should be :
f(x) = 58

1.A study was created to test the effects of jazz on people's sleep patterns. The hypothesis of the experiment was
that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment,
2 groups of people were created. Group I was placed in a quiet room where they went to sleep and they were timed
on how long they slept. The Group 2 was placed in a room where jazz music played softly as they began to sleep and
played throughout the night. As each group awoke, their sleep times were monitored.

Step-by-step explanation:
The independent variable is the one which is not altered by any outer influence. For example the jazz music will not be interrupted by the sleeping habits of people.
The dependent variable is the one which is affected by external changes such as sleeping time is afffected by external music or noises.

what is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?
Answers
Answer:
y = 4/3x - 6
Step-by-step explanation:
The slope of the 1st line is -3/4
So for the perpendicular line it has to be the exact opposite.
That looks like this ---> 4/3x
And the y-intercept is -6 because if you make a straight line where the x intercept is it matches.
The equation would look like this
y = 4/3x - 6

Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line
