Answers

Answer 1
Answer: Yes, the two ratios are proportional
In 3/4, if you multiply the numerator and denominator by 3, you would get 9/12, thus, 3/4=9/12

What are the values of x in the equation 4x2 + 4x – 3 = 0

Answers

Answer:

x = -3/2, 1/2

Step-by-step explanation:

(2x + 3)(2x - 1) = 0

2x + 3 = 0, 2x = -3, x = -3/2

2x - 1 = 0, 2x = 1, x = 1/2

Solve the following system of equations graphically on the set of axes belowy = 3x - 6
y = -x+2

Answers

Answer:

y = 3x - 6

y = -x+2

Final answer:

To solve the system of equations graphically, graph both equations on a set of axes, then find the intersection point, which is the solution to the system.

Explanation:

To solve the system of equations graphically, we first need to graph each equation on a set of axes.

The first equation, y = 3x - 6, is a straight line with a slope of 3 and a y-intercept (where the line crosses the y-axis) at -6. To graph this, start at point (0, -6) on the y-axis, then move up 3 units and to the right 1 unit to find the next point. Repeat this process to plot several points, then draw a straight line through them.

The second equation, y = -x + 2, is also a line, but with a slope of -1 and a y-intercept at 2. Start at point (0, 2) on the y-axis, then move down 1 unit and to the right 1 unit. Draw a straight line through the points.

The solution to the system of equations is the point where the two lines intersect on the graph. By examining the graph, you can determine this point.

1 megameter=______km can you help me pleasse

Answers

1 Mm = 1,000,000 m

and

1,000 m = 1 km

we need to convert 1,000,000 meters to kilometers using the conversion 1 m = 1,000 km.

\sf{1,000,000~m * (1~km)/(1,000~m)= 1,000 *1~ km = \boxed{\bf{1,000~km}}

So:

1 megameter = 1,000 km.

-What is the midpoint between the points (7, 3) and (-5, 5)?

Answers

Answer:

The midpoint is ( 1,4)

Step-by-step explanation:

To find the x coordinate of the midpoint add the x coordinates of the endpoint and divide by 2

( 7+-5)/2 = 2/2 =1

To find the y coordinate of the midpoint add the y coordinates of the endpoint and divide by 2

( 3+5)/2 = 8/2 =4

The midpoint is ( 1,4)
