the members of senior class are planning a dance. they use the equation s=2r+t/x to determine the total receipts. what is r in t

Deffense [45]

Answer:

r = 1/2(s -t/x)

Step-by-step explanation:

Here, we simply want to make r the subject of the formula;

We proceed as follows;

s = 2r + t/x

s - t/x = 2r

Divide both sides by 2

r = 1/2(s - t/x)

Solve 5x-97>-34 or 2x+31<29

Komok [63]

I'll do both.

$5x-97>-34\Rightarrow x>\frac{-34+97}{5}=\frac{63}{5}=\boxed{12.6} \\\boxed{x\in(12.6, \infty)} \\ \\2x+31$

What is 0.5×(-0.6) ×0.4= and pls show how

blondinia [14]

Answer:

$- 0.12$

Step-by-step explanation:

1) Solve inside the parentheses.

$(0.5 \times - 0.6)$

2) Simplify (0.5 × - 0.6 ) to -0.3.

$- 0.3 \times 0.4$

3) Simplify -0.3 × 0.4 to -0.12.

$- 0.12$

Therefor, the answer is -0.12 .

Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the

Zanzabum

Answer:

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule $R(O,90^\circ)\circ r_{y=-x}(x,y)$ . Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to $r_{y=-x}(x,y)$ , we get

$(x,y)\rightarrow (-y,-x)$

According to $R(O,90^\circ)$ , we get

$(x,y)\rightarrow (-y,x)$

The rule $R(O,90^\circ)\circ r_{y=-x}(x,y)$ means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

$K(4,7)\rightarrow K'(-7,-4)$

After rotation, we get

$K'(-7,-4)\rightarrow K''(4,-7)$

Therefore, the correct option is C.
