Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.

I'll help you by example. Let's look at the first problem:

"Evaluate 6(z-1) at z-4."

Due to "order of operations" rules, we must do the work inside the parentheses FIRST. Replace the z inside (z-1) with "-4". We obtain

6(-4-1) = 6(-5) = -30 (answer.)

Your turn. Try the next one. If it's unclear, as questions.

Line QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR?

kari74 [83]

For this we will use equation that gives us equation of line that goes through 2 given points.

that equation is:
$y - y1= \frac{y2 - y1}{x2 - x1} (x - x1)$

now we implement our given coordinates.
let Q be point 1 and R be point 2
y - 1 = 6/2(x - 0)
y - 1 = 3x

Answer is b.

Grade 5 farm has 85 rows of cabbages.If there are 58 cabbages in each row ,how many cabbages are there in the farm to the neares

ElenaW [278]

The number of cabbages on the farm to the nearest thousand is 5000 based on the given parameters

<h3>How to determine the number of cabbages on the farm to the nearest thousand</h3>

The number of rows is given as:

Number of rows = 85

The number of cabbage on each row is

Number of Cabbage on each row = 58

The number of cabbages on the farm is calculated as:

Farm = Number of rows * Number of Cabbage on each row

Substitute the known values (i.e. Number of rows = 85 and Number of Cabbage on each row = 58) in the above equation

Farm = 85 * 58

Evaluate the product of 85 and 58

Farm = 4930

Approximate the above result (i.e. 4930) to the nearest thousand

Farm = 5000

Based on the given parameters, the number of cabbages on the farm to the nearest thousand is 5000

So, the complete parameters are:

Number of rows = 85

Number of Cabbage on each row = 58

Number of Cabbage in the farm = 5000
