To have infinitely many solutions the two equations are essentially the same line.  So any multiple of the original equation will have infinitely many solutions with respect to the original equation....

In this case 2x+2y=4 = 2(x+y=2)  so they are the same line and have infinitely many solutions.  Because each point on one line is at the same point on the other line...

Mona needs to photocopy a 10.5 centimeters wide by 16 centimeters long picture. She wants to enlarge the picture so that its len
Inga [223]

Original Picture:

Width: 15 cm

Length: 16 cm

Enlarged Picture:

Width: unknown

Length: 48 cm

The new length is 48 cm, and the original length is 16 cm.

How many times larger is the new length than the old length?

We divide 48 by 16 to get 48/16 = 3

The new length is 3 times larger than the original length.

This means that the new width will also be 3 times the original width.

Original width: 15 cm

New width: 3 * 15 cm = 45 cm

Answer: 45 cm

Colin invests £4800 into his bank account.
weeeeeb [17]

Answer:

$5903.39

Step-by-step explanation:

This can be solve using compound interest formula. The formula is:

F=P(1+r)^t

Where

F is the future amount (what we are looking for)

P is the present amount (which is 4800)

r is the rate of compound interest per year, in decimal (3% per year, 3/100 = 0.03)

t is the time in years ( t = 7)

Now we substitute these values into the formula and find F:

F=P(1+r)^t\\F=4800(1+0.03)^7\\F=4800(1.03)^7\\F=5903.39

So, Colin would have $5903.39 after 7 years, in his account.

Choose the correct range for the quadratic function?
Ray Of Light [21]

Answer:

-2 \le y < \infty

Step-by-step explanation:

The range is the set of values of the y-coordinates of all the points in the function.

We see in the graph that the lowest y-coordinate is -2. The graph goes up from -2 on both sides all the way to infinity. The range is -2 and all values greater than -2.

Answer: -2 \le y < \infty
