Marco is turning the expression (x-4)^2 into a trinomial. He writes down what is shown below. What is his error?
Answer:
Step-by-step explanation:
first, let's solve the equation ourselves.
(x-4)^2= (x-4)(x-4)= x^2−8x+16
now, we can see what's different about the two.
we can say that Marco's answer had the number 16 as a negative, when it was supposed to be positive. Marco wrote the incorrect sign.
if 2:7 is expressed in the form for 4. Find the value of x.
Answer:
x = 14
Step-by-step explanation:
Given that,
2:7 is expressed in the form for 4:x.
We need to find the value of x.
2:7 must be equated to 4:x.
So,
[tex]2:7=4:x\\\\or\\\\\dfrac{2}{7}=\dfrac{4}{x}\\\\x=\dfrac{7\times 4}{2}\\\\x=14[/tex]
So, the value of x is equal to 14.

Write a function to describe the following scenario.
Emily plants a rosemary bush that starts at 5
centimeters in height and grows 3 centimeters
per year. How high will the rosemary be after a
certain number of years?
y = [?]x +
Answer:
y(x) = 3x + 5
Step-by-step explanation:
Since the rosemary grows by the same number of centimeters each year, this situation is modeled by a linear function.
Height starts at 5 meters and grows 3 centimeters per year.
This means that the height after a certain number of years, represented by x, is given by:
y(x) = 3x + 5

Laura goes to the carnival and receives 60 tokens to play games.
•each game required 4 tokens.
•At the end of the evening she used all of her tokens,how many games did laura play?
A.10
B.15
C.16
D.24
Answer: (B) 15
Step-by-step explanation:
Laura had 60 tokens to use and each game required 4 of them. By the end of the evening all of her tokens had been spent.
Let x represent the number of games Laura has played. Since Laura used up all of her tokens we can determine that for some integer x, 60 - 4x = 0
Solve for x
60 - 4x = 0
- 4x = - 60
x = [tex]\frac{60}{4}[/tex]
x = 15
Therefore, Laura played 15 games by the end of the evening

A factory produces blue pens and black pens. Each week, 2/3 of the pens produced at the factory are black.
Write and solve an equation that can be used to determine the number of blue pens (x) produced at the factory in a week when 45,000 pens are produced.
Answer:
15,000
Step-by-step explanation:
1/3 times 45,000 = 15,00
The number of blue pens produced at the factory in a week when 45,000 pens are produced is 15,000.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
A factory produces blue pens and black pens.
2/3 of the pens produced at the factory are black.
If T is the total pens produced at the factory, then the number of black pens produced is 2/3 T.
Number of blue pens = T - 2/3 T = 1/3 T
Given that,
Total pens produced = 45,000
Equation to find the number of blue pens is,
x = 1/3 × 45,000
Solving,
x = 15,000
Hence the number of blue pens produced is 15,000.

When you translate, you add or subtract the value you are moving to each coordinate
(6,7) left 5 would be -5 to the x coordinate and 3 up would be +3 to the y coordinate.
6-5=1
7+3=10
new point is (1,10)
moving left 5 units is subtracting 5 from the x value:
6-5 = 1
Moving up 3 units is adding 3 to the y value:
7 + 3 = 10
The answer is (1,10)

95 + 95 + z + z = 360
190 + 2z = 360
2z = 170
z = 85

The original price of a
42-inch TV is $399. An
electronics store is
offering the TV for
15% off of the original
price plus a $25
discount. How much
will the TV cost after
both the sale and
discount?
A) $314.15
B) $40.00
C) $326.85
D) $359.00
PLEASE HELP
Answer:
$314.15 (A)
Step-by-step explanation:
We start by subtracting the 15% discount. 15% can be represented by 0.15, and 100% can be represented by 1. So therefore, the new price of the TV will be 1-0.15 = 0.85 of the original price using just the 15% discount. Therefore, 0.85 x 399 = $339.15. We then take this number and subtract another $25 to get $314.15
The first sequence rule is multiply by 2 starting from 7. The second sequence rule is add 2 starting from 8. What is the first number that appears in both sequences?
Question 3 options:
10
14
18
28
The first and the second sequence are arithmetic and geometric sequence, respectively
The first number in both sequences is 14
How to determine the first number?From the question, we have the following rules
Rule 1Start = 7
Multiply by 2
Rule 2Start = 8
Add = 2
So, the numbers in the sequence are:
Rule 1: 7, 14, 28, 56......
Rule 2: 8, 10, 12, 14, .....
By comparing the numbers in the sequence, we can see that the first number in both sequences is 14
