Answer:
Step-by-step explanation:
In order to combine like terms, you have to isolate x and y from one side of the equation.

<u>First, thing you do is remove parentheses.</u>

<u>Solve.</u>
<u>Then, you combine like terms.</u>

<u>Add/subtract the numbers from left to right.</u>
-8z+3.5z=-4.5z
<u>Rewrite the problem down.</u>

<u>Solve.</u>
4.5-1.5=3

- <u>Therefore, the correct answer is 7y+3-4.5z.</u>
I hope this helps, let me know if you have any questions.
Step-by-step explanation:
the slope of a line is always the factor of x.
here : 1/2
it is the ratio y/x indicating how many units y changes, when x changes a certain angina amount of units when going from one point to another.
a perpendicular slope puts x and y upside-down and flips the sign.
here : -2/1 = -2
so, the equation looks like
y = -2x + b
b is the y-intercept, and we get this by putting the x and y coordinates of the given point into this equation and solve for b :
-1 = -2×-2 + b
-1 = 4 + b
b = -5
the full equation is therefore
y = -2x - 5

i'm guessing u must be from UK.... in the US "standard form" is known as "Scientific Notation"
Write 3.25 x 10^4 as an ordinary number: 32 500
Write 6.04 x 10^-3 as an ordinary number: 0.00604
Write 2 400 000 in standard form : 2.4 x 10^6
Write 0.00147 in standard form: 1.47 X 10^-3

Is it possible for you to explain it a little more?
Step-by-step explanation:
I believe one answer could be (4x4)=16-10=6+12=18+10=28-4=24?
