kaheart [24]

Answer:

We use negative values for the money Arleen spends.

a) We determine the change to the value on her gift card:

4(-35)+(-9)= -140+(-9)=-149

b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:

200+(-149)=51

Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:

51>50

RESULT

a) -$149 less b) yes

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?

Vlad1618 [11]

Answer:

$(x,y)\rightarrow(x-3,y+5)$

Step-by-step explanation:

"5 units up" would be "5 added to the current y-value".

"3 units to the left" would be "3 subtracted from the current x-value".

So, the translation rule is:

$(x,y)\rightarrow(x-3,y+5)$

Therefore, Option C should be the correct answer.

lina2011 [118]

Answer:

The correct option is C). proportional; congruent; similar

Step-by-step explanation:

Theory :

If triangle is dilated from the origin at a scale factor of 2 to create Triangle then, image of triangle and original triangle are similar to each other

Also, for similar triangles, corresponding angles are equal or congruent and corresponding sides are in ratio or scaled

For example : Figure show that triangle ABC is dilated by factor of 3 and centered at (-5,-4)

Question say: The triangles' corresponding sides are ________, and their corresponding angles are ________; therefore, the triangles are ________.

Answer : The triangles' corresponding sides are <u>proportional</u> and their corresponding angles are <u>congruent </u>therefore, the triangles are <u>similar</u>
