3. Consider the straight line x + y = 1 and the family of straight lines that pass
through the origin given by y = mx. As m changes the line rotates about the
origin. Solve these two systems of linear equation and find their points of inter-
section. Is there always a solution - If yes, briefly explain why. If not - for what
a
values of m is there no solution.

Answers

Answer 1

Answer:

solution: (1/(1+m), m/(1+m))no solution for m = -1 (lines are parallel)

Step-by-step explanation:

Two distinct lines will always have a point of intersection, provided they are not parallel. That is, the system of equations {x +y = 1, y = mx} will have a unique solution as long as m ≠ -1.

The solution to the system can be found by substitution:

  x +mx = 1

  x(1 +m) = 1 . . . . factor out x

  x = 1/(1+m) . . . . . divide by the coefficient of x; we must have m ≠ -1

  y = m/(1+m) . . . . find the y-coordinate of the solution

The point of intersection is (1/(1+m), m/(1+m)).

__

The above solution is undefined when the denominator is zero: m = -1. There is no solution for m = -1.

Answer:

(A) 33.9 (B) 22.6

Step-by-step explanation:

We first need to round to the nearest dollar for both prices. Lets examine both numbers.

$30.12       $19.93

We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.

Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now

[tex]30*0.13=3.9[/tex]           [tex]20*0.13=2.6[/tex]

Now we can find the final price for each number by adding the tax to the rounded price.

[tex]30+3.9=33.9[/tex]          [tex]20+2.6=22.6[/tex]

Hence, (A) 33.9, (B) 22.6

1)

[tex]a+b=125 +1/3\\a=125.33-b\\\\2) ab=36+1/2\\[/tex]

at this point you can insert the equation you got from 1.

The linear inequality represented by the graph is y ≤ 1/2x + 2

How to determine the inequality?

From the graph, we have the following highlights:

The graph crosses the y-axis at c = 2The graph is a less than or equal to graph

Next, we calculate the slope (m) using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

Using the points on the graph, we have:

[tex]m = \frac{4 -2}{4 -0}[/tex]

Evaluate

m = 1/2

The first highlight implies that the y-intercept is 2.

So, the linear inequality is:

y ≤ mx + c

This gives

y ≤ 1/2x + 2

Hence, the linear inequality represented by the graph is y ≤ 1/2x + 2

The fraction that represents the addition model shown above will be 53/100.

How to solve the fraction?

From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.

Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.

Therefore, the problem that represents the addition model shown above will be:

= 5/10 + 3/100

= 50/100 + 3/100

= 53/100

In this case, the answer given by Emma is incorrect as he added 5 to 3 and got 8/100.

Answers

I believe your answer is 798 yards^2

The perimeter and the area of the shape are 63 square yards and 46 yards, respectively.

How do we calculate?

The area of a triangle is equal to one half the product of its base and height. In the image, the base of the triangle is 18 yards and the height is 7 yards. Therefore, the area of the triangle is:

area = (1/2) * base * height

= (1/2) * 18 * 7

= 63 square yards

The perimeter of the shape is the sum of the lengths of all of its sides. In the image, the lengths of the sides are 6 yards, 18 yards, 7 yards, and 15 yards.

Therefore, the perimeter of the shape is:

perimeter = 6 + 18 + 7 + 15

= 46 yards

Hunter is 35 years older than Andrew. After 5 years Hunter will be twice Andrew's age. Find the present age of both.

Answers

Answer:

Andrew is 30 years old. Hunter is 65 years old.

Step-by-step explanation:

we can set up 2 equations:

h = 35 + a

h+5 = 2(a+5)

Solve for h in the second equation.

h + 5 = 2a + 10; h = 2a + 5

now set the 2 equations = to each other

2a + 5 = 35 + a

solve for a by combining like terms

a + 5 = 35

a = 30

so Andrew is 30 and Hunter is 35 + 30 = 65.

Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)

Answer:

Let h represent Hunter's AgeLet a represent Andrew's Age.

So that means that

h=35+a+5

because he already is 35

we add Andrew's Age

And we add 5 for 5 extra years

Therefore,

35 + 5 + a = 2(a + 5)

35+5=40.

40+a = 2a+10

Substract the a

40 = a+10

Subtract 10

30 = a

If Andrew's age is 30, going back to our first equation,

h = 35 + 30 (previously a) + 5

Hunter's Age = 65

Andrew's Age = 30

surface area of triangular prism = 1240 yd²

surface area of cone = 791.28 ft²

Step-by-step explanation:

cuboid formula = 2( l x b + l x h + h x b )

solution:

S.A = 2(l x b + l x h + h x b)

S.A = 2(5 x 3 + 5 x 10 + 10 x 3)

S.A = 2(15 + 50 + 30)

S.A = 2( 95 )

S.A = 190 in²

triangular prism formula = 2(1/2 (b x h)) + 2(l x b) + l x b(this formula can only be used for this type of triangular prism)

solution:

S.A = 2(1/2 (b x h)) + 2(l x b) + l x b

S.A = 2(1/2 (15 x 16)) + 2(17 x 20) + 20 x 16

S.A = 240 + 680 + 320

S.A = 1240 yd²

cone formula = [tex]\pi[/tex]r(l + r) or [tex]\pi[/tex]rl + [tex]\pi[/tex]r²

solution:

S.A = [tex]\pi[/tex]r[l+r]
