X+ 3y = 15 and 4x+2y= 30
O (6,3)
O (3,6).
O (7,-6)
O (-6, 7)
Answer:
6,3
Step-by-step explanation:
given equtions are
x+3y=15______(1)
4x+2y=30______(2)
multiplying (1) by 4
on solving, 4x+12y=60_____(3)
substracting eqution (3) and (2)
4x+12y-(4x+2y)=60-30
⇒10y=30
on solving,
y=3
substituting the value of y in equation (1)
x+3(3)=15
on solving,
x=6
Answer:
A
Step-by-step explanation:
(6,3)
write the equation of a line that passes through the point (12, 5) and has a slope of -3
Answer:
y - 5 = -3(x - 12)
General Formulas and Concepts:
Algebra I
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate y₁ - y coordinate m - slopeStep-by-step explanation:
Step 1: Define
Point (12, 5)
Slope m = -3
Step 2: Write Function
Plug in variables into the general formula.
Substitute [PSF]: y - 5 = -3(x - 12)6) Steven receives $5.75 per hour and 3% commission on sales. One week he worked 40 hours and sold $2,500

The system of equations y=-2x+3 and y=x is graohed. What is the solution to the system of equations
Answer:
The solution to this system of equations is y = 1, x = 1
Step-by-step explanation:
We know that...
(1) y = - 2x + 3
(2) y = x
Then we just substitute the value of x that we are given in equation (2).
And so we get....
y = -2x + 3
x = - 2x + 3
3x = 3
x = 1
From equation (2) we know that y = x, so since x equals 1 y is also 1. There for the solution to this system of equations is (1,1)

Given that the endpoints of a diameter are (7,-3) and (-1,7), determine the equation of the circle.
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^r
H and k are the x and y coordinates of the center of the circle and r is the radius.
You are given the diameter coordinates so find the halfway point for the center then calculate the radius
Midpoint = (x1 +x2)/2, (y1 + y2)/2
Midpoint = (7 + -1)/2, (-3 +7)/2
Midpoint = 6/2, 4/2
Midpoint = 3,2
So h = 3 and k = 2
Now find radius by finding the distance between the center point and an end point.
Distance = sqrt(41)
Equation of the circle:
(X-3)^2 + (y-2)^2 = 41
Answer:
The equation of the circle is written as:
(x-h)²+(y-k)²=r²
'h' and 'k' are the x and y coordinates of the center of the circle and 'r' is the radius.
You are given that the diameter coordinates, so find the halfway point for the center then calculate the radius
[tex]Midpoint = ( \frac{x_1 + x_2 }{2}, \frac{y_1 + y_2}{2} ) \\ = ( \frac{7 + ( - 1)}{2} , \frac{ (- 3 )+ 7}{2} ) \\ = ( \frac{6}{2} ,\frac{4}{2} ) = (3,2)[/tex]
So, h=3 and k=2
Now find the radius by finding the distance between the center point and the end point.
Distance=√{(7-3)²+(-3-2)²}=√{(4)²+(-5)²} =√{16+25}=√41
Equation of the circle:
(x-3)²+(y-2)²=41 ✓

Calculate the volume, in cubic centimeters, of a box which is 125 cm long, 37 cm wide, and 68 cm high. Report your answer with correct significant figures in cubic centimeters.
Answer:
[tex]Volume = 314500cm^3[/tex]
Step-by-step explanation:
Given
[tex]Length = 125cm[/tex]
[tex]Width = 37cm[/tex]
[tex]Height = 68cm[/tex]
Required
Determine the volume
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
Substitute values for Length, Width and Height
[tex]Volume = 125cm * 37cm * 68cm[/tex]
[tex]Volume = 314500cm^3[/tex]
Hence, the volume of the box is [tex]314500cm^3[/tex]

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?
3/4 of a foot?
Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
[tex]x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25[/tex]
So
3/4 of a foot will cost $2.25.
