Start by converting to like terms, so convert 1/2 to 2/4.

Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.

If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!

Choose the equation below that represents the line passing through the point (−2, −3) with a slope of −6.

Daniel [21]

Y=mx+b where m=-6, x=-2, and y=-3. Substituting these values in would result in -3=(-6)(-2)+b, which would simplify to -3=12+b, and further to b=-15. This would mean the y intercept is equal to -15, or (0,-15). To check, (-6)*(-2)-15 is in fact equal to -3, thus allowing easy identification of a graph, which will cross the y axis at -15 and decrease in y-value by 6 with every increase in x-value.

I have to explained it in words pls help

Answer:

slope: cost per mile
y-intercept: fixed base cost

Step-by-step explanation:

The y-intercept is the value of y when x=0. The problem statement tells you that x is the number of miles driven, and y is the rental cost.

When the number of miles driven is zero, the rental cost is ...

y = 2.25×0 +70

y = 70

The cost of renting the truck is $70 when it isn't driven anywhere. The y-intercept ($70) is the basic, fixed cost of truck rental.

If x=1 (1 mile driven), then 2.25 is added to the cost of the truck rental. The slope (2.25) is the cost per mile driven. (That mileage cost is added to the basic rental cost.)

Look for a pattern in the first three diamonds below. For the fourth diamond, explain how to find the missing numbers (?) if you

murzikaleks [220]

The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)

<h3>What is the general pattern in the diamonds?</h3>

Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.

<h3>What numbers complete the diamonds?</h3>

Diamond A

Top number: 15 (3x5)

Bottom number: 8 (3+5)

Diamond B

Top number: 2 (-2x-1)

Bottom number: -3(-2+-1)

Diamond C

4, 2 because 4x2 = 8 and 4+2 = 6

Diamond D

Top number: 4( 8x0.5)

Bottom number: 8.5(8+0.5)

Diamond E

-3,-4 because -3x-4= 12, and -3+-4= -7
