Answer:
-2.9375
Step-by-step explanation:
2x-14x+47=0
16x+47=0
16x=-47
x=-2.9375
Answer:
x=7+√ 2 or x=7-√ 2
Step-by-step explanation:
x^2-14x+47=0
Completing the square,
x^2-14x+49-2=0
x^2-14x+49=2
x^2-7x-7x+49=2
x(x-7)-7(x-7)=2
(x-7)^2=2
x-7=√ 2 or x-7=-√ 2
x=7+√ 2 or x=7-√ 2

what is the result of (4³)² × (¼)²
Answer:
256
Step-by-step explanation:
By using power of a power rule, the result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.
What are exponential formulas?Exponents formulas refer to the formulas that help solve exponents. Exponent of a number is represented in the form: [tex]x^{n}[/tex], meaning x is multiplied by itself for n times. Here,
x is called the "base"
n is called the "exponent" or "power"
[tex]x^{n}[/tex] is read as "x to the power of n" (or) "x raised to n"
Power of a power rule : [tex](a^{m} )^{n}=a^{mn}[/tex]
Given exponential expression
[tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex]
[tex](4^{3} )^{2}[/tex] is in the form of power of a power rule [tex](a^{m} )^{n}=a^{mn}[/tex]
= [tex]4^{6}[/tex] × [tex]\frac{1}{4^{2} }[/tex]
= [tex]4^{4}[/tex] × [tex]4^{2}[/tex] × [tex]\frac{1}{4^{2} }[/tex]
= [tex]4^{4}[/tex]
= 256
The result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.

Franco begins to save for a new Lego set that costs $65. His parents gave him $35 towards the cost
and he plans to save $5 per week. Define all unknown variables. Write an equation modeling the total
amount he has saved.
Answer:
65-35=30
30 divided by 5 = 6
Step-by-step explanation:
First you have to subtract 65-35, which equals 30.
Then the problem says he plans to save 5 each week. That means he should get his lego set in 6 weeks, because 30 divided by 5 = 6
65-35=30
30 divided by 5 = 6

Alan says that two lines in the coordinate plane are perpendicular if and only if the slopes of the lines are m and 1m. Identify and correct two errors in Alan’s statement.
Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.

Find x so that l is parallel to m.
Answer:
Step-by-step explanation:
(10x + 17)° = 87° + 5x° (This is because of the rule of corresponding angles)
=> 10x° = 87° + 5x° - 17°
=> (10x - 5x)° = 87° - 17°
=> 5x° = 70°
=> x° = ( 70/5 )°
=> x° = 14°
Therefore x = 14°

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2
which tile's side lengths will Dorian need to estimate?
Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm

You are preparing for a trip to Canada. At the time of your trip, each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar. a. You exchange 150 U.S. Dollars for Canadian dollars. How many Canadian dollars do you receive?
Answer:
193.95 Canadian dollars
Step-by-step explanation:
Given: Each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar.
To find: Value of 150 U.S. dollars in terms of Canadian dollars
Value of 1 U.S. dollar = 1.293 Canadian dollars
To find 150 U.S. dollars in terms of Canadian dollars, multiply 150 by 1.293
Value of 150 U.S. dollars in terms of Canadian dollars = 150 × 1.293 = 193.95 Canadian dollars
1. Given x=5, plug x into y=10x-2.
a. 38
b. 12.
C. 13
d. 48
Answer:
D. 48
Step-by-step explanation:
y=10x-2 is our equation
If x is 5, then multiply 10 by 5. You get 50.
Subtract 2 from that. You get 48.
Answer:
D, 48
Step-by-step explanation:
Given x=5, plug x into y=10x-2
First you should plug the given x into the x in the equation. And put () around it.
y=10(5)-2
Now you multiply 10 by 5 and you get 50.
y=50-2
Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.
y=48
