What is the graph for 3x+7>22

Mathematics
2 answers:

3x + 7 > 22

3x + 7 - 7 > 22 - 7 ... subtract 7 from both sides

3x > 15

3x/3 > 15/3 ... divide both sides by 3

x > 5

To graph this, draw out a number line. Plot an open circle at 5. Do not fill in this open circle. The shade to the right. The shading represents every number larger than 5. The unfilled open circle means "do not include this endpoint".

Answer:

<h3>Look at the picture</h3>

Step-by-step explanation:

3x+7>22\qquad\text{subtract 7 from both sides}\\\\3x+7-7>22-7\\\\3x>15\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}>\dfrac{15}{3}\\\\\boxed{x>5}

<,> - open circle

≤, ≥ - closed circle

<, ≤ - draw a line to the left

>, ≥ - draw a line to the right

Instructions: Write the explicit rule. Remember to simplify and do not put spaces in your answer. Sequence: 30,0,−30,−60,… 30 ,
kodGreya [7K]

Answer:

a(n)=60-30n

Step-by-step explanation:

Equation to use:

a(n) = a(1) + d(n-1)

where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.

In this case, a(1) is 30, d is -30, and n is just n.

If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.

Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.

Use the polygon tool to graph the reflection of this rectangle across the x-axis.
iVinArrow [24]

Answer:

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices of the given rectangle ABCD,

A(3, 6), B(12, 6), C(12, 1) and D(3, 1)

Rule for the reflection of a point across x-axis,

(x, y) → (x, -y)

After reflection of the given rectangle across x-axis image points will be,

A(3, 6) → A'(3, -6)

B(12, 6) → B'(12, -6)

C(12, 1) → C'(12, -1)

D(3, 1) → D'(3, -1)

Now we can plot these points on the graph to get the image of rectangle ABCD.
