Answer:

see explanation

Step-by-step explanation:

given 4x + 4y = 15

substitute x = - 5 into the equation and solve for y

- 20 + 4y = 15 ( add 20 to both sides )

4y = 35 ( divide both sides by 4 )

y = $\frac{35}{4}$ ← missing coordinate

the ordered pair is (- 5, $\frac{35}{4}$ )

Write the equation of the line with a slope of 1/2 that passes through the point (-6,10)

Katen [24]

Answer:

An equation is

$y = \frac{1}{2} x + 13$

Step-by-step explanation:

☆Since since we're given the slope, all we need to do is find the y-intercept.

☆The slope-intercept formula is: y = mx + b.

☆We are going to plug in according to the formula.

$y = mx + b \\ \\ 10 = \frac{1}{2} ( - 6) + b \\ 10 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: \: \: \: \: }{13 = b \: \: \: \: \: \: \: \: \: \: \: }$

☆We have everything we need, so now we put it together.

Erin Lytle's gross pay is $26,300. She takes a married exemption of $4,000. Her state income tax rate is 5.5%. How much will she

Stells [14]

Given

Erin Lytle's gross pay is $26,300

She takes a married exemption of $4,000

state income tax rate is 5.5%

Find out she pay in state income tax

To proof

Gross pay = $26,300

married exemption = $4,000

Let the she pay in state income tax = x

5.5 % written in the simpler form

= $\frac{5.5}{100}$

= 0 .055

than the equation becomes

x = 0.055 ( 26300 - 4000)

x = 0.055× 22300

x = $1226.5

Erin Lytle pay in state income tax is $ 1226.5

Hence proved

Show that the set of functions from the positive integers to the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} is uncountable. [Hint: First

Sedbober [7]

Answer:

since the set of functions expressed are uncountable and they are a subset of real numbers starting from N therefore the set {0,1,2,3,4,5,6,7,8,9} is uncountable as well as its off functions

Step-by-step explanation:

set = {0,1,2,3,4,5,6,7,8,9}

setting up a one-to-one correspondence between the set of real numbers between 0 and 1

The function : F(n)= {0,1} is equivalent to the subset (sf) of (n) , this condition is met if n belongs to the subset (sf) when f(n) = 1

hence The power set of (n) is uncountable and is equivalent to the set of real numbers given

since the set of functions expressed are uncountable and they are a subset of real numbers starting from N therefore the set {0,1,2,3,4,5,6,7,8,9} is uncountable as well as its offfunctions

If two integers are positive, the one closer to zero is_________greater

finlep [7]

Answer: C) Never

If two integers are positive, the one closer to zero is <u> never </u> greater.

An example would be something like the integers 3 and 5. The value 3 is closer to zero, so it's not greater than 5. Stuff on the left is smaller than stuff on the right.
