Answer:
30 x 0.4
Step-by-step explanation:
Tamara rewrote the expression 0.2(4+1.4y -2.1). Her steps are shown.
Step 1: 0.2(4+1.4-2.1)
Step 2: 4.2+1.6 - 1.9
Step 3: 4.2-1.9+1.6y
Step 4: 2.3+1.67
Which statement identifies and explains the first mistake Tamara made?
Her first mistake was in Step 2. She added 0.2 to each term instead of multiplying by 0.2.
Her first mistake was in Step 2. She should have only added 0.2 to 4 instead of adding 0.2 to all 3 terms.
© Her first mistake was in Step 3. When reordering the terms, the 1.6y should be negative and the 1.9 should be
positive.
Her first mistake was in Step 3. When reordering the terms, 1.9 should be the coefficient of y rather than 1.6.

The statement that identifies and explains the mistake made by tamara was,
Her first mistake was in Step 2. She added 0.2 to each term instead of multiplying by 0.2.
The correct option is option A)
What is multiplication?
Multiplication is one of the basic arithmetic operation in which we take the product of two or more terms. The other basic operation is addition, subtraction and division.
We are given an expression 0.2(4+1.4y-2.1)
To compute simplify and find the value of y,
We multiply 0.2 inside we get the following,
(0.8+0.28y-0.42)
Instead of performing multiplication operation like this she added 0.2 in each and every term
This was the mistake made by her
Hence, The statement that identifies and explains the mistake made by tamara was,
Her first mistake was in Step 2. She added 0.2 to each term instead of multiplying by 0.2.
The correct option is option A)

Please help me solve ASAP
Answer:
Step-by-step explanation:
first just look at the graph
its very obvious its a linear graph because it is going up in a straight line at a steady pace
so we can then just ignore the answers that say its not a linear function
then since its straight and not curved (curved graphs or parabolas are found when x has an exponent) its obvious it cant be one of the equations with x^2
so we are left with one the final answer
its equation is y = x + 2 and it is a linear function

A motorboat moves across a lake at a constant speed. When it begins, it is 48
km from the shore. After 10 minutes, it is 18 km from the shore. Which
function describes the motorboat's distance from the shore?
O A. y = 10x+48
B. y=-3x + 48
O c. y=-10x + 48
O D. y = 3x + 48
Answer:
b
Step-by-step explanation:
The function describes the motorboat's distance from the shore is y=-3x + 48. So, the correct option is B.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, a motorboat moves across a lake at a constant speed.
Let x be the number of minutes and y be the total distance.
When it begins, it is 48 km from the shore.
Now, (x₁, y₁) =(0, 48)
After 10 minutes, it is 18 km from the shore.
So, (x₂, y₂) =(10, 18)
We know that, Slope(m) =(y₂-y₁)/(x₂-x₁)
= (18-48)/(10-0)
= -30/10
= -3
Substitute, (x, y)=(0, 48) and m=-3 in y=mx+c, we get
48=-3(0)+c
c=48
Substitute, c=48 and m=-3 in y=mx+c, we get
y=-3x+48
Therefore, option B is the correct answer.

Does this scatter plot show a positive trend, a negative trend, or no trend?
Answer:
no trend
a positive trend would start in the bottom left and go toward the top right
a negative trend would start at the top left and go town the bottom right
this is an example of no trend
Step-by-step explanation:
a "trend" shows an increasing or decreasing relationship between the x and y values, in this they don't have any sort of relationship. you can tell by the repeating y values for multiple different x-values, or the repeating x-values for multiple different y-values.
