X - 4/2 ; where x = -1.6
Substitute x by its value.
-1.6 - 4/2 *as you notice, one number is in decimal and the other is in fraction form. We need to convert one form to the other to make the numbers like numbers so that solving the equation will be easier and less confusing.
4/2 can easily be converted into decimal by dividing 4 by 2 which equals to 2.
So, -1.6 - 2 = ? The operation is a subtraction, but the other number is in negative form, if both numbers have the same sign, we add them up and the sign is carried over to the sum.
-1.6 -2 = -3.6 * we add 1.6 + 2 = 3.6, then we carry over its negative sign = -3.6
4(x+8) - 10 >= 42
4x + 32 - 10 >= 42
4x + 22 >= 42
4x >= 20
x >= 5 (true on number line)
answer is D. last one
Answer:
First question: (0, 1) (-4, 0)
Step-by-step explanation:
FIRST QUESTION:
y=3x+1
y=x-7
In the first equation of the first question, (y=3x+1) the 3 represents the slope and the 1 represents the y-intercept. Therefore, your first coordinate is (0, 1).
To figure out the second coordinate, do this:
Substitute y for x-7
x-7=3x+1
Combine like terms
x=3x+8
-3x+x=8
-2x=8
Divide the entire equation by -2
x=-4
Therefore, your second coordinate is (-4, 0).
SECOND QUESTION:
I am really sorry, I can't see the second question very well. It's a little too blurry and I have bad eyesight.
Hope this helps a little.
Answer:
D, D, B
Step-by-step explanation:
multiply 744 by 1,000 to get your meters.
7 times the cost of each lawn, X will equal 210.
