Answer: Third option.
Step-by-step explanation:
Let be "x" the approximate actual width of the car (in feet).
According to the information provided in the exercise, you know that the scale of the model car is:
By definition, this can be written as a fraction:
Therefore, if you know that the width of the model car is 2.3 inches, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value.
This is:
Answer:
A
Step-by-step explanation:
Point A:
The original coordinate of point A was (-6,-6).
The coordinate after the transformation is A'(1,6), which eliminates option 3.
Point B:
The original coordinate of point B was (-2,4).
After the transformation, we have B'(5,-4), which eliminates option 1 and option 4. This means that the correct answer is:
<u>2. (x,y) → (x+7,-y)</u>
Follow the order of operation: PEMDAS
Parenthesis
Exponents (and roots)
Multiply
Divide
Add
Subtract
3 x (7-2) + 4
first do Parenthesis (as it shows up first)
7 - 2 = 5
Next, Multiply (the next one you have to do)
5 x 3 = 15
Finally, add
15 + 4 = 19
B. 19 is your answer

1/2 ÷ 1/2
= 1/2 ÷ 2/1
= 1/2 × 2/1
= 2/2
= 1
Answer:
(x - 4)
Step-by-step explanation:
Given x = a is a root then (x - a) is the corresponding factor
Given x = 4 is a root, then
(x - 4) ← is the corresponding factor
Note if x = - 4 is a root , then
(x - (- 4)), that is (x + 4) is the corresponding factor
