Use the graph to determine the number of solutions the system has. x=4 y=x+3

Lyrx [107]

Answer:

Final answer is x=4, y=7.

Step-by-step explanation:

Questions says to use the graph to determine the number of solutions the system has. where system of equations are x=4 and y=x+3

any equation of the form x=k is a vertical line crossing x-axis at k.

So x=4 is a vertical line crossing x-axis at 4.

y=x+3 has slope m=1 and y-intercept b=3

So it passes through point (0,3) and for slope m=1, rise 1 up then 1 right to get new point.

Then final graph is given as shown in the picture.

We can see that both lines intersect at point (4,7).

Hence final answer is x=4, y=7.

Express 900 as a product of its prime factors in index form. Write the prime factors in ascending factors.

Lina20 [59]

Answer:

900 = 2 * 2 * 3 * 3 * 5 * 5 = 2^2 * 3^2 * 5^2

Step-by-step explanation:

900/2 = 450

450/2 = 225

225/3 = 75

75/3 = 25

25/5 = 5

5/5 = 1

900 = 2 * 2 * 3 * 3 * 5 * 5 = 2^2 * 3^2 * 5^2

3x+2=x+4(x+2) how do you do it step by step?

Katena32 [7]

Distribute 4 with x and 2 to get the equation 3x+2=x+4x+8. Combine x and 4x to get 5x. Minus 3x from each side. Now you should have 2=2x+8. Subtract 8 from both side to get -6=2x. Divide and you get x=-3
