Tell whether the relation is a function (3,-2)(0,1)(1,0)(-2,-1)(2,-1)

2 answers:

8 0

Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.

answer: it's a function

explanation: the reason why it's a function is when the x's are NOT repeating itself. when it's not a function, it the x's ARE repeating itself.

Ms. Fontanges wants to put a line of bricks along the back edge of her yard. She needs 35 feet of bricks. The bricks she wants t

Oliga [24]

Answer:

$41.16

Step-by-step explanation:

Length of bricks required = 35 feet, length of brick sold = 10 inches, cost of 10 inches brick = $0.98 per brick

Total number of brick required to build the back yard = Length of bricks required ÷ Length of brick sold

1 ft = 12 inches

Number of brick required = (35 * 12) ÷ 10

Number of bricks required = 42 bricks

Cost of brick required = Per length cost of brick * Number of bricks required

Cost of brick required = 0.98 * 42

Cost of brick required = $41.16

Ms. Fontanges would spend $41.16 on the purchase of bricks

Given the two options above, in order to come up with the best plan we have to calculate the future value of money in each plan.
compound interest is given by: $FV=p(1+ \frac{r}{100})^n$

Option 1
p=$500
r=2%=0.02
t=1 year
$FV=500(1+0.02)^1=$510$

Option 2
p=$500
r=2/12=1/6
n=1*12=12
hence:
$FV=500(1+\frac{ \frac{1}{6}}{100})^{12}
$
=$509.09
Comparing the two plans above, option 1 is the best.

b] Option 1 is the best because she will secure $510 as compared to option 2 which has interest rate that reduces her amount by $1 after one year due to annual charges. The total amount of money she will have at the end of the plan is $510.

Solve for x in equation x-c/2=d

lana66690 [7]

X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c
