Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
x - y = 4x + y = 4Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.

A design for a building has a scale of 1/3 inch = 4 meters. On the blueprint
(drawing of the building), the length of the building is 2 2/3 inches. What is the
actual length of the building?
Answer:
32 m
Step-by-step explanation:
The length of the building on the drawing is 2 2/3 = 8/3 inches, so represents a length that is 8 times the length represented by 1/3 inch.
8 × 4 m = 32 m
The actual length of the building is 32 meters.

what is the quotient of 5.76×7 and 9.0×10 to the fourth power expressed in scientific notation?
Answer:
4.48 ×10^-4
Step-by-step explanation:
Now putting the sentence into a mathematical relationship (recall that quotient is the result of division). We have;
5.76 ×7 / 9.0×10^4 = 40.32/90000= 4.48 ×10^-4
Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians and engineers.
The general format for writing scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one. a may also be expressed as a decimal as in the answer above. a may also be equal to or greater than 10 as the case maybe. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

write the measurement 1357 mm into the place value table below
m I cm I mm
I I
Answer:
m=1.357 cm=135.7 mm=1357
Step-by-step explanation:
m=1357 Divided by 1000
cm=1357 Divided by 10
The measurement 1357 mm into the meters, centimeters, and mm are 1.357, 13.57, and 1357 respectively.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
It is given that:
The measurement is 1357 mm
As we know,
1 m = 100 cm
1 cm = 10 mm
Or
1 m = 100 cm = 1000 mm
The measurement is 1357 mm
It can be converted into m after dividing by 1000
= 1357/1000
= 1.357 m
In cm:
Divide by 10
= 1357/10
= 13.57
Thus, the measurement 1357 mm into the meters, centimeters, and mm are 1.357, 13.57, and 1357 respectively.

A store sells a 114 pound package of turkey for $9.
What is the unit price of the turkey in the package?
Answer:
Each pound of turkey in the package cost 7.20 dollars.
Step-by-step explanation:
If you wanted a explanation then comment
Answer:
$7.20
Step-by-step explanation:
The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!

When a number is increased by 28%, the result is 47. What is the original number to the nearest tenth?
Answer:
The original number was 36.7.
Step-by-step explanation:
Multipliers:
The multiplier for a increase of a% is 1 + a/100.
The multiplier for a decrease of b% is 1 - b/100.
In this question:
The original value is x.
Increased by 28%, so we have that 1 + (28/100) = 1.28x. Equals 47. We have to find x.
1.28x = 47
x = 47/1.28
x = 36.7
The original number was 36.7.

The discriminant of the equation x2 + x - 30 = 0 is?
The solution(s) of the equation x +x-30 = 0 is/are?
Answer:
discriminant: 11solutions: -6, +5Step-by-step explanation:
Comparing your equation to the standard form, we can find the values necessary to compute the discriminant:
x^2 +x -30 = 0
ax^2 +bx +c = 0
So, we have ... a = 1, b = 1, c = -30
The discriminant is defined as ...
d = √(b² -4ac) = √(1² -4(1)(-30)) = √121
d = 11
The solutions are ...
x = (-b ± d)/(2a) = (-1 ±11)/2
x = {-6, +5}

Cara is painting her living room. The room measures 10.6 feet by 11.6 feet. The ceiling is 10 feet
high
If paint covers 400 square feet, per gallon, and costs $14.95 a gallon, how much will it cost to paint
Cara's room?
Answer:
$29.90
Step-by-step explanation:
Can you only buy paint by the gallon? That is what I am thinking.
She is painting 4 walls. I am thinking that she is not painting the floor or the ceiling.
The area of the four walls would be:
(11.6 x 10) = 116
(11.6 x 10) = 116
10.6 x 10) = 106
(10.6 x 10) = 106
This totals 444 square feet. Since a gallon can only paint 400 square feet, she will need to buy 2 gallons for 29.90

Gita must pay $ (blank) in taxes on her investment income.
Answer:
Gita must pay $ 487.50 in taxes on her investment income
Step-by-step explanation:
Without mincing words Gita falls into income tax brackets of $38,601 and $425,800 from qualified dividends and long-term capital gains perspective since he had wages of $50,000 and other income totaling $3,250($2500+$750)
As a result,the taxes on her investment income of $3,250 is 15% of the investment income.
investment income taxes=$3,250*15%=$ 487.50

Here,
y = dependent variable
x = independent variable
a = intercept
b = slope
The data is provided for the number of free throws a player makes in a basketball game and the number of points the player scores in the game.
The free throw in a basketball game implies that for every throw shot made the player receives point.
This implies that the points scored are based upon the number of free throws made by a player.
So, the dependent variable is the number of points scored and the independent variable is the number of free throws a player makes.
Then the regression equation of the data will be:
[tex]s=6.2f+1.7[/tex]
