If a bat and ball costs $1:10

2 answers:

3 0

X = bat, y = ball

x + y = 1.10
x = y + 1

y + 1 + y = 1.10
2y + 1 = 1.10
2y = 1.10 - 1
2y = 0.10
y = 0.10/2
y = 0.05 <=== the ball

x = y + 1
x = 0.05 + 1
x = 1.05 <== the bat

Which of the sets of ordered pairs represents a function? A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3),

jek_recluse [69]

Answer:

Neither A or B

Step-by-step explanation:

Hello There!

In order for a set of ordered pairs to represent a function none of the x values can repeat

In answer choice A the x value 7 repeats therefore the set of ordered pairs do not represent a function

In answer choice B the x value 7 repeats therefore the set of ordered pairs do not represent a function

so we can conclude that neither set of ordered pairs represent a function

Answer:

$a = 7.5$

Step-by-step explanation:

Given

$\frac{10}{14} = \frac{a}{10.5}$

Required

The value of a

Cross multiply

$a * 14 =10 * 10.5$

Make a the subject

$a = \frac{10 * 10.5}{14}$

$a = \frac{105}{14}$

$a = 7.5$

Find the midpoint of the segment below and enter its coordinates as an

Sati [7]

Answer:

(-1/2,5)

Step-by-step explanation:

Here is the complete question

Find the midpoint of the segment with endpoints of (1, 4) and (-2, 6) and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

Solution

The mid-point of a line is given by ((x₁ + x₂)/2,(y₁ + y₂)/2). From the question, x₁ = 1, y₁ = 4, x₂ = -2 and y₂ = 6. So,

((x₁ + x₂)/2,(y₁ + y₂)/2) = ((1 + (-2))/2,(4 + 6)/2)

= ((1 - 2)/2,10/2)

= (-1/2,10/2)

= (-1/2,5)
