5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying

5x + 8 = ?

If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8

45 + 8 = 53

Therefore 5x + 8 = 53

Hope this helps you! :)

Can someone help me with this question please?

tensa zangetsu [6.8K]

Answer:

a.) (0,4) b.) (-4,0)

Step-by-step explanation:

a.) Let x=0 and solve for y: y=0+4=4. Since we let x=0 the first number will be 0 and we found y to be 4, so our coordinates are (0,4)

b.) Let y=0 and solve for x: 0=x+4, x=-4. Since x=-4 our first number is -4, since y is 0 our second number is 0, so our coordinates are (-4,0)

Hope this helps!

How many solutions does this system have?

Leokris [45]

Answer:

The correct option is d.

Step-by-step explanation:

The given equations are

$x-2y=2$ .... (1)

$y=-2x+5$ .... (2)

In equation 2, multiply both sides by 2.

$2y=-4x+10$ .... (3)

Now add equation (1) and (3).

$x-2y+2y=2+(-4x+10)$

$x=2-4x+10$

$x+4x=12$

$5x=12$

Divide both sides by 5.

$x=\frac{12}{5}=2.4$

Put this value in equation (2).

$y=-2(2.4)+5$

$y=-4.8+5$

$y=0.2$

Therefore the solution of the system of equation is (2.4,0.2) and the system has only one solution. Option d is correct.
