The row-echelon form of the augmented matrix of a system of equations is given. Find the solution of the system.
Zepler [3.9K]

Answer:

option-C

Step-by-step explanation:

We are given row-echelon form

So, we can write equation from matrix as

x-5z=-3

y-4z=-5

Let's assume

z=t

now, we can find x and y

x-5t=-3

x=5t-3

y-4t=-5

y=4t-5

so, we get solutions as

x=5t-3

y=4t-5

z=t

where t can be any real numbers

. If a = 120°, find the measure of angles b, c and d.<br> Explain your reasoning.
Alchen [17]
∡b is a vertical angle to ∡a and therefore a twin, and we know that ∡a = 120°, thus since ∡b = ∡a, ∡b = 120° as well.

a full circle has a total of 360°, ∡d and ∡c are vertical angles, namely two angles across from each other at a junction, and therefore ∡d = ∡c.

∡a + ∡b is 120° + 120° thus 240°, since a circle has a total of 360°, 360 - 240 = 120, so the other two angles pick up that slack and divide it among each other evenly, 120/2 = 60, so ∡d = ∡c = 60°.

Find two numbers with a sum of 20 and a difference of 14
sergey [27]

Find two numbers with a sum of 20 and a difference of 14


Make two equations

X+Y=20

X-Y=14


Now add x since y cancels out and add 20+14 To end up with

2x=34


Now divide 2 both sides to get x alone

2x/2=34/2


X=17


Now substitute x answer to first equation and solve for y

17+y=20


Subtract 17 both sides

Y= 3

Your two numbers are

3 and 17
