Answer:

Step-by-step explanation:

(x,y)→(x+5,y)

(-4,-1)→(-4+5,-1)=(1,-1)

reflection about x-axis

(x,y)→(x,-y)

(1,-1)→(1,1)

Answer:

(1, 1)

Step-by-step explanation:

If we move the point (-4, -1) to the right 5 units, then we add 5 to the x value to give us (1, -1). We reflect (1, -1) in the x-axis, so we change the y value this time multiplying it by -1. The new point that (-4, -1) would be mapped onto would be:

(1, 1).

I hope this helps you!! ^-^

The length of the rectangle is six times its width if the perimeter is 70cm find its area
Vesna [10]

Answer:

Step-by-step explanation:

Perimeter is 70 m

so w + w + 6w + 6w = 70

w = 70/14 = 5, l = 30m.

Area = l * w = 30 * 5 = 150 sq m

This is a bit confusing?
kow [346]

Answer:

  • Noah: 3 cups
  • Lin: 4 cups

Step-by-step explanation:

When the 12-cup bag of sugar is divided evenly, each baker gets 6 cups.

There is no dot on Noah"s graph for 6 cups of sugar, so you have to extrapolate the given set of dots to see where it might be. You notice that each dot is 1/2 cup of flour more than the one to its left, so you expect that Noah will use 3 cups of flour for 6 cups of sugar.

__

Similarly, the table for Lin does not have an entry for 6 cups of sugar. Again, the next entry can be figured using the relations between previous entries. Here, each row for sugar goes up by 1 1/2 cups, so the next row would be 4 1/2 + 1 1/2 = 6 cups. And the rows for flour go up by 1 cup, so the next row for flour (for 6 cups of sugar) would be 4 cups of flour.

Lin will use 4 cups of flour for 6 cups of sugar.

__

<em>Alternate solution</em>

The relationship are proportional in both cases, so you can read the value for a smaller amount (2 cups or 3 cups of sugar), then multiply the value by an appropriate multiplier (3 or 2) to get the number of cups of flour for 6 cups of sugar.

Noah: 1 flour for 2 sugar ⇒ 3 flour for 6 sugar

Lin: 2 flour for 3 sugar ⇒ 4 flour for 6 sugar

Seven less than the product of a number and 10 is 50
Veseljchak [2.6K]
<span>product of a number and 10: 10n
</span><span>Seven less than the product of a number and 10: 10n - 7
so
</span><span>Seven less than the product of a number and 10 is 50:</span>
10n - 7 = 50
----------------------------
if you need to find the number n then
10n - 7 = 50
10n = 57
    n = 57/10
    n = 5.7
