Answer:

(7,-11)

Step-by-step explanation:

We are given the rule of: $(x,y)\rightarrow(x+3,y-2)$ .

Apply the rule to point P:

$(4,-9)\rightarrow(4+3,-9-2)\rightarrow\boxed{(7,-11)}$

P' should be (7,-11).

Hope this helps.

A school is painting its logo in the shape of a triangle in the middle of its sports field. The school wants the height of the t

Radda [10]

Answer:

$b\geq 9$

In other words, the base must be at least 9 feet long.

Step-by-step explanation:

The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.

Recall that the area of a triangle is given by:

$\displaystyle A = \frac{1}{2}bh$

Since we want to area to be at least 36 square feet:

$\displaystyle \frac{1}{2}bh \geq 36$

We are given that the height is eight feet. Substitute:

$\displaystyle \frac{1}{2}(8)b\geq 36$

Simplify:

$4b\geq 36$

Divide both sides by four. Hence, our inequality is:

$b\geq 9$

In words, this means that the base must be at least 9 feet long.

Identify the correct corresponding parts

andrey2020 [161]

Answer:

The correct corresponding part is;

$\overline {CB}$ ≅ $\overline {CD}$

Step-by-step explanation:

The information given symbolically in the diagram are;

ΔCAB is congruent to ΔCED (ΔCAB ≅ ΔCED)

Segment $\overline {CA}$ is congruent to $\overline {CE}$ ( $\overline {CA}$ ≅ $\overline {CE}$ )

Segment $\overline {CB}$ is congruent to $\overline {CD}$ ( $\overline {CB}$ ≅ $\overline {CD}$ )

From which, we have;

∠A ≅ ∠E by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

∠B ≅ ∠D by CPCTC

Segment $\overline {AB}$ is congruent to $\overline {DE}$ ( $\overline {AB}$ ≅ $\overline {DE}$ ) by CPCTC

Segment $\overline {AE}$ bisects $\overline {BD}$

Segment $\overline {BD}$ bisects $\overline {AE}$

Therefore, the correct option is $\overline {CB}$ ≅ $\overline {CD}$
