{10x-4y=-6
{-3x+4y=-1
WORK MUST BE SHOWN
Answer:
x = -1
y = -1
Step-by-step explanation:
10x - 4y = -6 ---------------------(I)
-3x + 4y = -1 ---------------------(II)
Add equation (I) & (II) and y will be eliminated.
10x - 4y = - 6
-3x + 4y = -1 {Add}
7x = - 7
x = -7/7
x = -1
Plugin x =-1 in equation (I)
10*(-1) - 4y = -6
-10 - 4y = -6 {Add 10 to both sides}
-4y = -6 + 10
-4y = 4 {Divide both sides by (-4)}
y = 4/(-4)
y = -1
10. If log10x = 1 + a and log10y = 1 – a, show that xy = 100.
How?
Step-by-step explanation:
log x = 1 + a
a = log x - 1
log y = 1 - a
a = 1 - log y
So
log x - 1 = 1 - log y
log x + log y = 2
log (xy) = 2
xy = 100

A model maker wants to make a model of a
ship
He will use a scale of 1:50
The ship was 100ft long
1 foot = 0.3 m
How long will the ship be in cm?
9514 1404 393
Answer:
60 cm
Step-by-step explanation:
The model ship will be x feet long, where ...
x/100 = 1/50
x = 100/50 = 2
In meters, that is ...
2(0.3 m) = 0.6 m
A meter is 100 cm, so the length in centimeters is ...
(0.6)(100 cm) = 60 cm

Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana. The area of the base of the aquarium can be represented by the expression (42x3−14x2+21x) feet3. If the width of the aquarium is represented by the expression (7x) feet, what is the length of the aquarium?
Answer:
[tex]Length = 6x^2 - 2x + 3[/tex]
Step-by-step explanation:
Given
[tex]Area = 42x^3 - 14x^2 + 21x[/tex]
[tex]Width = 7x[/tex]
Required
Determine the length of the aquarium
The area of a rectangular base is calculated as:
[tex]Area = Length * Width[/tex]
Substitute values for Area and Width
[tex]42x^3 - 14x^2 + 21x = Length * 7x[/tex]
Make Length the subject
[tex]Length = \frac{42x^3 - 14x^2 + 21x}{7x}[/tex]
Factorize the numerator
[tex]Length = \frac{7x(6x^2 - 2x + 3)}{7x}[/tex]
[tex]Length = 6x^2 - 2x + 3[/tex]

Answer:
P ≈ 100
Step-by-step explanation:
260 = P(1+0.054/365)^365(14)
260 = P(1.000147945)^5110
260= P(2.129621112)

An infinite number of ratios are equivalent to 3:8. How
can that be possible, when the multiplication table only
goes to 9?
Answer:
See below, please!
Step-by-step explanation:
There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.
For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

2x plus 3 plus x2; for x = 4
Answer:
2x+3+x2 if x=4 is 27
Step-by-step explanation:
2*x or 2*4=8
8+3=11;
and x or 4 times itself is 16
so we add it all together and get 27.
Have a great day!
Answer:
27
Step-by-step explanation:
Not sure if you mean x to the power of 2, so I'll assume that.
Replacing the variable for 4 should look like:
2(4) + 3 + 4^2
8 + 3 + 16 (4 to the power of 2 is equivalent to 4 x 4 which is 16)
Now add them all, 27.
During the months of August and September the total rainfall I August was 0.6 inch more than the amount f rainfall in September, how much rain fell in each month?
Answer:
August = 3.4
September = 2.8
Step-by-step explanation:
Given
[tex]Total = 6.2\ in[/tex]
Represent August with A and September with S.
So,
[tex]A =S + 0.6[/tex]
Required
Amount of rainfall in each month.
This is calculated using:
[tex]Total = August + September[/tex]
[tex]6.2= A + S[/tex]
Recall that: A = S + 0.6. Substitute
[tex]6.2= S + 0.6 + S[/tex]
[tex]6.2= 2S + 0.6[/tex]
Collect Like Terms
[tex]2S = 6.2 - 0.6[/tex]
[tex]2S =5.6[/tex]
Solve for S
[tex]S = 5.6/2[/tex]
[tex]S = 2.8[/tex]
Substitute 2.8 for S in [tex]A =S + 0.6[/tex]
[tex]A = 2.8 + 0.6[/tex]
[tex]A = 3.4[/tex]

The classroom rug is 9 feet long and has an area of 72 square feet. What is the perimeter of the rug?
Answer:
34 Ft.²Explanation:
Area = width · length
The length of the rug is 9 feet. We need to find the width.
72 ÷ 9 = 8
Check to see if this is correct: width (8) · length (9) = area (72)
Now add the length and width together two times since a rug has 4 sides
8 + 8 + 9 + 9 = 34
The perimeter of the rug is 34 ft.²

The table shows the linear relationship between x, the altitude in feet, and y, the boiling point of water in degrees Fahrenheit. What are the slope and y- intercept of the line that models this situation?
A. Slope=- 0.0018, y-intercept = 212
B. Slope= 0.0018, y-intercept =-212
C. Slope =212, y- intercept= 0.0018
D. Slope=-212, y-intercept = 0.0018
Answer:B
Step-by-step explanation
The slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data in the table is,
Altitude(x) Boiling point (y)
0 212.0
500 211.1
The slope will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 211.1 - 212 ) / (500 - 0 )
Slope = -0.0018
The y-intercept will be calculated as,
y = mx + c
212 = 0 + c
c = 212
Therefore, the slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.
