Graph the system of equations 4x+4y=16 x+6y=-6

Mathematics
1 answer:
never [62]3 years ago
7 0

Answer:

Graph has been shown in the attached file.

Step-by-step explanation:

We have been given the system of equations

4x+4y=16.......(1)\\x+6y=-6.........(2)

Both the equation represents a straight lines. We can find the x and y intercepts of these lines to graph.

The intercept form of a line is given by

\frac{x}{a}+\frac{y}{b}=1

Here a is the x - intercept and b is the y-intercept.

Divide both sides of the equation (1) by 16

\frac{4x}{16}+\frac{4y}{16}=1\\\\\frac{x}{4}+\frac{y}{4}=1

Hence, x-intercept = 4 and the point is (4,0)

y-intercept = 4 and the point is (0,4)

Similarly, for the second line

Divide both sides of the equation (2) by -6

\frac{x}{-6}+\frac{6y}{-6}=1\\\\\frac{x}{-6}+\frac{y}{-1}=1

x-intercept = -6 and the point is (-6,0)

y-intercept = -1 and the point is (0,-1)

We'll plot these points in the xy- plane and then join to get the graph of these lines.

What is the slope y+2=1/4(x-3)
ioda

Answer:

m=\frac{1}{4}

Step-by-step explanation:

Given

y+2=\frac{1}{4}(x-3)

Required

Find the slope

y+2=\frac{1}{4}(x-3)

Subtract 2 from both sides

y+2-2=\frac{1}{4}(x-3) - 2

y=\frac{1}{4}(x-3) - 2

Open bracket

y=\frac{1}{4}x-\frac{1}{4}*3 - 2

y=\frac{1}{4}x-\frac{3}{4} - 2

Take LCM

y=\frac{1}{4}x+\frac{-3 - 8}{4}

y=\frac{1}{4}x+\frac{-11}{4}

y=\frac{1}{4}x-\frac{11}{4}

An equation has the form:

y = mx + b

Where

m = slope

By comparing: y = mx + b and y=\frac{1}{4}x-\frac{11}{4}

m=\frac{1}{4}

<em>So, the slope is 1/4</em>

A race is 25 miles long. There is a water station every 1 1/4 miles along the race route. How many water stations are needed for
Vikentia [17]

Answer:

21

Step-by-step explanation:

21 water stations

Step-by-step explanation:

From the question, we are informed that a marathon is 26.2 miles long and that there is a water station every 1 1/4miles along the race route and at the finish line.

To get the number of water stations that are needed for this marathon, we divide 26.2 miles by 1 1/4miles. This will be:

= 26.2miles/1 1/4 miles

= 26.2 miles/1.25 miles

= 20.96

= 21 water stations

A random sample has been selected from a population. The point estimate = 78.65 and margin of error E = 8.24 for a 90% confidenc
fiasKO [112]

Answer:

90% confidence interval: (70.41,86.89)

Step-by-step explanation:

We are given the following in the question:

Point estimate = 78.65

Margin of error, E = 8.24

Confidence level = 90%

Significance level = 10%

Formula:

\text{Point estimate} \pm \text{Margin of error}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

78.65 \pm 8.24 = (70.41,86.89)

(70.41,86.89) is the required 90% confidence interval.
