Answer:
the range in interval notation is (-4, 4).
Step-by-step explanation:
"Range" refers to the set of numbers that contains all possible values of y that a given function can take on. In this diagram we see that the smallest possible y-value is -4 and the largest is +4, not inclusive (the set does not contain either -4 or +4). Thus, the range in interval notation is (-4, 4).

40) How old am I if 400 reduced by 3 times
my age is 214?
Answers
Answer:
You are 62 years old
Step-by-step explanation:
Let's set up an equation:
400 - 3a = 214 ( let a be your age)
Add 3a to each side:
400 = 214 + 3a
Subtract 214 from each side:
186 = 3a
Divide each side by 3:
62 = a

Answer:
[tex]y = \frac{2}{3}x - \frac{4}{3} [/tex]
Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope
[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{2 - - 4}{5 - - 4} = \frac{2 + 4}{5 + 4} = \frac{6}{9} = \frac{2}{3} [/tex]
substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b
[tex]y = mx + b \\ 2 = \frac{2}{3} (5) + b \\ 2 = \frac{10}{3} + b \\ 2 - \frac{10}{3} = b \\ \frac{6}{3} - \frac{10}{3} = b \\ b = - \frac{4}{3} [/tex]
substitute the slope and the value for b into the equation to get the answer
[tex]y = \frac{2}{3} x - \frac{4}{3} [/tex]

2. Find the value of "a" given the vertex and a second point when the vertex is (3,-1) and the graph passes through (5, 2)
Answers
Answer:
a = 3/4
Step-by-step explanation:
Given the vertex, (3, -1) and the other point, (5, 2):
We could substitute these values into the vertex form of the quadratic equation:
y = a(x - h)² + k
Where:
(h, k ) = vertex
a = determines whether the graph opens up or down, and makes the graph wider or narrower.
If a is positive, the graph opens up; if a is negative, the graph opens down.If a is between 0 and 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
Substitute the vertex, (3, -1) and point (5, 2) into the vertex form to solve for "a":
y = a(x - h)² + k
2 = a(5 - 3)² - 1
2 = a(2)² - 1
2 = a(4) - 1
Add 1 to both sides:
2 + 1 = a(4) - 1 + 1
3 = 4a
Divide both sides by 4 to solve for a:
3/4 = 4a/4
3/4 = a
Therefore, the value of a = 3/4. Since the value of a is positive, and that it is between 0 and 1, then it means that the graph opens upward and is wider than the parent function.
The quadratic equation in vertex form is: y = 3/4(x - 3)² - 1, where a = 3/4.

Kaj bought snacks for her team's practice. She bought a bag of chips for $2.44 and a
20-pack of juice bottles. The total cost before tax was $26.44. Write and solve an
equation which can be used to determine j, how much each bottle of juice costs.
Answers
Answer:
j = $1.20
Step-by-step explanation:
26.44 (total cost) - 2.44 (cost of chips) = 24
$24 dollars (cost of pack of juice bottles) divided by 20 (number of juice bottles in the pack = 1.2
The required equation for the cost of 20 juice bottles is x = (26.44 - 2.44) / 20 and costs $1.2.
She bought a bag of chips for $2.44 and a 20-pack of juice bottles.
The total cost before tax was $26.44.
To determine and solve an equation that can be used to determine j, how much each bottle of juice costs.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the cost of the bottle be x,
According to the question,
2.44 + 20x = 26.44
20x = 26.44 - 2.44
x = [24] / 20
x = $1.2
Thus, the required equation for the cost of 20 juice bottles is x = (26.44 - 2.44) / 20 and costs $1.2.

the triangle shown in question 5 is congruent. also known as SSS (side,side,side). the reason why its SSS is because if you look at the triangle, you see 3 different lines on the outside. one has only one line, one has 2 lines, and one has 3 lines. this is an indication that the triangle is congruent. you could not say AAA (angle,angle,angle) because that does not mean the triangles are considered congruent.

Answers
Answer:
We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers

6x +5y = 45 . . . . . . total cost
x + y = 8 . . . . . . . . . number of items

These equations can be solved a number of ways. Substituting for y, we get ...
y = 8 -x
