can someone find the domain and range in this graph i’m having trouble
To find the domain of graph, we notice at the point on the left and the right.
Domain is the set of all x-values, so we perceive in a horizontal line or x-axis.
The first point on left is at x = -1 and the second point on the right is at x = 1.
Since the points are opened and therefore, the Inequality signs can only be > or <.
Therefore, the domain is -1 < x < 1
To find the range, similar to domain but we perceive vertical line or y-axis. Range is the set of all y-values.
We notice that the minimum point is -1 or y = - 1 and maximum point at 1 or y = 1.
Therefore, the range is -1 < y < 1

what are the coordinates of point G ,which divides DE un the ratio 2:3?
Answer:
(5, 7.8)
Step-by-step explanation:
There are several ways to solve this problem, but all of them involve similar triangles and ratios.
See the attached image.
The horizontal distance between points D and E is 11 - 1 = 10. If a segment 10 units long is divided in the ratio 2:3 (as shown by the two smaller segments of length a and b), then
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{10}=\frac{2}{5}[/tex]
"Cross-multiply" to get
5a = 20
a = 4
To get the x-coordinate of point G, add 4 to 1, the x-coordinate of D.
The x-coordinate of G is 1 + 4 = 5.
The same idea can be used on the second coordinate of G.
The vertical distance from D to E is 15 - 3 = 12.
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{12}=\frac{2}{5}[/tex]
5a = 24
a = 24/5 = 4.8
The y=coordinate of G is 3 + 4.8 = 7.8

The number line is attached in the solution.
What is number line?In math, a number line is a horizontal straight line with numbers placed at equal distances from each other along that line.
A number line is a pictorial representation of numbers on a straight line. It's a reference for comparing and ordering numbers.
Given is an expression, -4-(-1), we need to plot its solution on the number line,
So,
-4-(-1)
Opening the brackets,
= -4+1 [∵ (-) × (-) = +]
= -3
Plotting -3 in the number line, it will be put 3 units left from zero in the number line,
We put negatives number on the left side and the positive numbers on the right side of zero, in the number line,
For example, we are asked to put 7 in the number line, we will count 7 units to the right of zero in the number line, and suppose if we are asked to plot -6, then we will count 6 units to the left of zero in the number line.
The number line is extended from -∞ to +∞

How many ounces of a 15% alcohol solution must be mixed with 4 ounces of a 20% alcohol solution to make a 17% alcohol solution?
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
Answer:
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution
Step-by-step explanation:
Let x ounces of 11% alcohol must be mixed with the 2 ounces of 20% alcohol.
The amount of alcohol in 4 ounces solution is= ounces
= 0.8 ounces
The amount of alcohol in x ounces solution is= ounces
= 0.11 x ounces
Total amount of alcohol is = (4+x) ounces
According to the problem,
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution
