Point A(7, 3) is translated to A prime (16, negative 9). Which rule describes the translation? (x, y) right-arrow (x minus 9, y minus 12) (x, y) right-arrow (x minus 9, y + 12) (x, y) right-arrow (x + 9, y + 12) (x, y) right-arrow (x + 9, y minus 12)

Answers

Answer:

$(x,y) -----> (x+9,y-12)$

Step-by-step explanation:

we know that

$A(7, 3) ----> A'(16,-9)$

The rule of the translation is equal to

$(x,y) -----> (x+a,y+b)$

Find the values of a and b

$(7,3) -----> (7+a,3+b)$

we have that

$7+a=16$ ----> $a=16-7=9$

$3+b=-9$ ----> $b=-9-3=-12$

substitute the values of a and b

$(x,y) -----> (x+9,y-12)$

That means----> The translation is 9 units right and 12 units down

sarah used 3/4 pound of blueberries to make 1/2 cup of jam. how many pounds of blueberries would she need to make a cup of jam? write your answer as an improper fraction.

Answers

Answer: She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .

Step-by-step explanation:

Since we have given that

Sarah used $(3)/(4)$ pound of blueberries to make $(1)/(2)$ cup of jam.

As we need to find the number of pounds of blueberries she would need to make a cup of jam.

So, we will use "Unitary Method":

$\text{For }(1)/(2)\text{ cup of jam},\n\n\text{ she need }(3)/(4)\text{ pound of blueberries }\n\n\text{ For 1 cup of jam}.\n\n\text{She need }=(3)/(4)* 2=(3)/(2)=1(1)/(2)\text{ pounds of blueberries }$

Hence, She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .

Given a=5, d=3,an =50 .find the n and 5n

Answers

Answer:

Step-by-step explanation:

an = 50

a +(n-1)d = 50

5 + (n-1)*3 = 50

(n-1)*3 = 50 - 5 = 45

n-1 = 45/3

n-1 = 15

n=15+1 = 16

n = 16

Answer:n=10, 5n=50

Step-by-step explanation:

an=50

n=50/a

n=50/5=10

5n=5×10=50
