Answer 1

Answer:

1/2

Step-by-step explanation:

8x+2y=4

To find x-intercept say y=0 and solve the equation.

8x+2(0)=4

8x=4

x=4/8

x=1/2

Answer 2
Let Y = 0
8x = 4
X = 1/2

Answer:

y=-3/4x-4

Step-by-step explanation:

To start, you know what m is; it's just the slope, which you said was -3/4. So you can right away fill in the equation for a line somewhat to read:

y=-3/4x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-8,2). When x of the line is -8, y of the line must be 2.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-8,2).

So, why not plug in for x the number -8 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-8,2). y=mx+b or 2=-3/4 × -8+b, or solving for b: b=2-(-3/4)(-8). b=-4.

The equation of the line that passes through the point (-8,2) with a slope of -3/4

is

y=-3/4x-4

Could I please get some help with this? Thank you!

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x+3y=15?

Answers

Answer:

y = 3/2x + 3/2

Step-by-step explanation:

perpendicular to: y = -2/3x + 5

so slope of new line must be 3/2

y = mx + b

3 = 1(3/2) + b

6/2 = 3/2 + b

b = 3/2

Carefree offers two type of care packages. The food packages sell for 20$ and the game packages sell for 32$. In one day Carefree sold 25 Care packeges. the receipt for those packages totaled 602$ How many of each type of package were sold

Answers

Answer:

Number of game package = 16.5

Number of food package = 8.5

Step-by-step explanation:

LET :

Food package = a

Game package = b

a + b = 25 - - - (1)

20a + 32b = 602 - - - (2)

a = 25 - b

Put a = 25 - b into (2)

20(25 - b) + 32b = 602

500 - 20b + 32b = 602

12b = 102

b = 102 / 12

b = 8.5

a = 25 - b

a = 25 - 8.5

a = 16.5

Number of game package = 16.5

Number of food package = 8.5

A long year-end status report for work is 134 pages long. You need to print 16 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.53 each. Give your answer to the nearest cent, only for the paper you use (partial reams are OK)

Answers

Answer:

The total cost of the copies will be $ 15.14.

Step-by-step explanation:

Given that a long year-end status report for work is 134 pages long, and I need to print 16 copies for a meeting next week, to determine how much is the paper going to cost for those reports if paper is sold in reams (500 pages) for $ 3.53 each the following calculation must be performed:

(134 x 16) / 500 = X

2,144 / 500 = X

4.288 = X

500 = 100

144 = X

144 x 100/500 = X

14,400 / 500 = X

28.8 = X

100 = 3.53

28.8 = X

28.8 x 3.53 / 100 = X

101.664 / 100 = X

1.016 = X

1.016 + (3.53 x 4) = X

1.016 + 14.12 = X

15,136 = X

Therefore, the total cost of the copies will be $ 15.14.

Step-by-step explanation:

Bryan and Jadyn had barbeque potato chips and soda at a football party. Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium. Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium. How much sodium is in 1 oz of chips and how much is in 1 cup of soda?

Answers

Answer:

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the amount of sodium in 1oz of chips.

y is the amount of sodium in 1 cup of soda.

Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.

This means that [tex]4x + y = 600[/tex], also [tex]y = 600 - 4x[/tex]

Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium.

This means that:

[tex]x + 4y = 300[/tex]

From the first equation, we have that [tex]y = 600 - 4x[/tex]. So

[tex]x + 4(600 - 4x) = 300[/tex]

[tex]x + 2400 - 16x = 300[/tex]

[tex]15x = 2100[/tex]

[tex]x = \frac{2100}{15}[/tex]

[tex]x = 140[/tex]

[tex]y = 600 - 4x = 600 - 4*140 = 40[/tex]

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.

The average annual cost of the first year of owning and caring for a cat is $1,500. A sample of 81 will be used. Based on past studies, the population standard deviation is assumed known with σ = $198. What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?

Answers

Answer:

The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Sample of 81

This means that [tex]n = 81[/tex]

What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]M = 1.96\frac{198}{\sqrt{81}}[/tex]

[tex]M = 43.12[/tex]

The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.
