Answer:
a = -3
b = -8
Step-by-step explanation:
Equation for a line is:
y-coordinate = (slope * x-coordinate) + y-intercept
For (3, -4): -4 = (-2 * 3) + y-intercept
y-intercept = 2
Equation for all points on this line is:
y = -2*x + 2
For (a, 8): 8 = (-2 * a) + 2
For (5, b): b = (-2 * 5) + 2

Identify the vertex and axis of symmetry of the graph of g(x) = |x|- 8
The vertex of the absolute function g(x) = |x|- 8 lies at (0,-8).
What is an absolute function?The absolute value or modulus of a real number x, denoted by |x|, is its non-negative value regardless of its sign.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the absolute function is g(x) = |x| - 8. The vertex will be calculated by plotting the function on the graph.
From the graph, the vertex of the absolute function lies at the point ( 0,-8). The graph is attached with the answer below.

2x+2y=2
-4x+4y=12
Answer:
how to solve 2x+2y=2 , -4x+4y=12
this is solving equations using substitution .... i have ALOT more but i juss dnt get this stuff
2x + 2y = 2 -4x + 4y = 12
x + y = 1
x = 1 - y
-4x + 4y = 12
-4(1 - y) + 4y = 12
(-4 + 4y) + 4y = 12
-4 + 8y = 12
8y = 16
y = 2
2x + 2y = 2
2x + 2(2) = 2
2x + 4 = 2
2x = -2
x = -1
Check.
-4x + 4y = 12
-4(-1) + 4(2) = 12
4 + 8 = 12
Answer: x = -1 and y = 2

Economists use market values when calculating GDP, because if they used quantity terms, they would have multiple units of measurement. Whereas, when they use market values, they have one unit of measurement for all products and services.

Researchers in plant growth are investigating the proportions of seedlings that sprout under two environmental settings in a lab experiment. Let pˆC represent the sample proportion of seedlings that sprout in garden C, and let pˆH represent the sample proportion of seedlings that sprout in garden H. For random samples of 100 garden C seedlings and 100 garden H seedlings, the sampling distribution of the difference between sample proportions pˆC−pˆH has σpˆC−pˆH≈0.051. Which of the following is the best interpretation of σPˆC−PˆH≈0.051 ?
Answer:
E
Step-by-step explanation:
For all random samples of 100 garden C seedlings and 100 garden H seedlings, the average distance of all possible differences between sample proportions pˆC−pˆH from the mean of the sampling distribution is approximately 0.051.

Sarah is conducting a science experiment where she initially has a population of 4 fruit flies. Every week the population triples. She writes the function f(x)=4(3)x to predict the population growth. Which rule can also model the function?
Answer and explanation:
Given that initial population of fruit flies = 4
And population of fruit flies triple every week
If population of fruit flies triple every week then let x represent number if weeks
Therefore function can be modelled thus :
f(x)= 4 + 3x
To demonstrate that the function is correct, we use an example. Now assume population grows for two weeks, using the function:
f(2)= 4+3×2
f(2)= 10
Therefore population grows to 10 fruit flies in 2 weeks based on our function

Answer: why?
Step-by-step explanation:
The area of a rectangle is 735 in squared. The ratio of the length to the width is 5 : 3. Find the length and the width.
Answer: Length = 35
Width = 21
Step-by-step explanation:
From the question, we are informed that the area of a rectangle is 735 in squared and that the ratio of the length to the width is 5 : 3.
To find the length and the width of the rectangle goes thus. We should note that the area of a rectangle is the length multiplied by the width.
Therefore, 5x × 3x = 735
15x² = 735
x² = 735/15
x² = 49
x = ✓49
x = 7
Recall that length = 5x = 5 × 7 = 35
Width = 3x = 3 × 7 = 21
