Answer:

Bidmas.

B =brackets

I= indices

D=division

M=multiplication

A=addition

S=subtraction.

The 19-4 is in brackets so this comes first. The answer is the top one..

a) one unit up = Ix + 2I + 1

b) one unit down = Ix + 2I - 1

c) one unit to the left = Ix + 1I

d) one unit to the right = Ix + 3I

Let the function f(x) and g(x) are two real functions.

And g (x) = f (x) + k, where k is real numbers.

Function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

The function provided by the basic function f(x) and the constant

g(x) = f(x - k),

may be drawn by horizontally moving the f(x) k unit coordinates.

The shift's direction depends on the value of k. Specifically,

The base graph moves k units to the right if k > 0, and

The base graph moves k units to the left if k < 0.

The graph of y = |x+2| is a V-shaped graph centered at x = -2.

To translate this graph, we need to modify the equation to shift it up/down or left/right.

Here are the equations for each translation:

a) To shift the graph one unit up, we need to add 1 to the equation:

y = |x+2| + 1

b) To shift the graph one unit down, we need to subtract 1 from the equation:

y = |x+2| - 1

c) To shift the graph one unit to the left, we need to replace x with (x+1) in the equation (since moving left means decreasing x by 1):

y = |(x+1)+2|

Simplifying this gives:

y = |x+3|

d) To shift the graph one unit to the right, we need to replace x with (x-1) in the equation (since moving right means increasing x by 1):

y = |(x-1)+2|

Simplifying this gives:

y = |x+1|

Therefore, all the required values are given above.

Answer:

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

[tex]\sf{x-5+5\leq10+5}[/tex]

Solve.

Add the numbers from left to right.

[tex]\sf{10+5=15}[/tex]

[tex]\Longrightarrow: \boxed{\sf{x\leq 15}}[/tex]

I hope this helps you! Let me know if my answer is wrong or not.

Let's solve this inequality.

First, we should add 5 to both sides:-

x≤10+5

x≤15

Remember, the "≤" sign means "less than or equal to"

So is x=6 a solution to the inequality x≤15? Will this solution make the inequality true?

Yes.

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

Answer:

5(2+y)

Step-by-step explanation:

The sum of 2 and y = 2+y
So,

5 times the sum of 2 and y(2 + y)  = 5 × (2+y) = 5(2+y)

The answer is 5(2+y)

Answer:

A. 3(2 + y)

Step-by-step explanation:

It's A. 3(2 + y) because when an equation is in parentheses then you have to do it first. So you would work out 2 + y and then multiply it by 3.

b) adjacent and complimentary

Step-by-step explanation:

Supplementary angles equal 180. Complimentary angles equal 90. 55+35 equals 90 and are next to each other therefore they are adjacent and comlimentary.

Answer:

2

Step-by-step explanation:

The average rate of change of the equation during the interval 4 ≤ x ≤ 10

can be represented in this expression if f(x) is substituted for y:

[tex]\dfrac{f(10)-f(4)}{10-4}[/tex]

[tex]=\dfrac{17-5}{6}[/tex]

[tex]=\dfrac{12}{6}[/tex]

[tex]=2[/tex]

So, the average rate of change (AOC) is 2.

You also could just figure this out by looking at the slope. Since this is a linear equation, the AOC over any interval will always be the same as the slope, since the slope is constant.

Outliers are just numbers or results that are very different to the rest of the numbers. hope this helps! :)

Answer:

The mean of 5 is because it includes the outlier more than the median

Step-by-step explanation:

Mean: ->             5

2 + 2 + 3 + 3 + 3 + 4 + 4 + 19 = ? / 8

40 / 8 = 5

Median: ->              3

Answer:

4 lines/sticks + 7 individual squares

Step-by-step explanation:

Decimal = 0.47

We can break 0.47 into 0.4 + 0.07. We can use 4 of the lines/sticks to represent 0.4 because the whole grid is equal to 1. We can use 7 individual squares to represent 0.07 because 1/100 is the same as one of the individual squares.

A semicircle whose diameter is 20 cm will have an area of 157 cm²

Answer:

b

Step-by-step explanation:

Answer:

the answer is 6 cm

Step-by-step explanation:

Here’s one way you can solve this problem.

A zoom setting of one hundred twenty percent means that the dimensions of the new copy will be one hundred twenty percent of the dimensions of the original drawing.

First, write the scale that expresses the ratio of the original percent to the copy percent, one hundred to one hundred twenty.

Then, let h represent the height of the copy and write the ratio of copy to original as five centimeters to h centimeters.

Next, write a proportion that equates the two ratios. One hundred to one hundred twenty equals five to h.

Then, cross multiply the terms of the proportion. One hundred twenty times five equals one hundred h.

Next, multiply to get six hundred equals one hundred h.

Finally, divide both sides by one hundred to find h. h equals six.

So, the longer dimension of the new drawing is six centimeters, which is one hundred twenty percent of five centimeters.
