Answer:

see explanation

Step-by-step explanation:

Either both equations are equal or are multiples of each other

As an example consider the 2 equations

4x - y = 2 → (1)

- 12x + 3y = - 6 → (2)

Multiply (1) by - 3

- 12x + 3y = - 6 → (3)

Subtract (3) from (2) term by term

(- 12x - (- 12)x) + (3y - 3y) = (- 6 - (- 6)), that is

(- 12x + 12x) + 0 = - 6 + 6

0 = 0

This indicates the solution has infinite solutions

let x = k, k is a real number then from (1) y = 4x - 2 ⇒ y = 4k - 2

Thus (k, 4k - 2) will generate solutions to the system of equations

Similar triangles are those triangles whose corresponding sides are in the same ratio. The area of the ΔDEF is 9.6 inches².

Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same.

For similar triangles, the ratio of their area is equal to the square of the ratio of their sides. Therefore, we can write for the given triangles,

(Area of ΔDEF)/(Area of ΔABC) = (4/5)²

Area of ΔDEF = (16/25) × 15 in²

Area of ΔDEF = 9.6 in²

Hence, the area of the ΔDEF is 9.6 inches².

recall that to find the x-intercept we set y = 0 and solve for "x".

and to find the y-intercept, we set x = 0 and solve for "y", so let's do so

x = 0, so then the equation turns into

y = 3x² + 5x - 2

y = 3(0)² + 5(0) - 2

y = -2

when x = 0, y = -2, ( 0 , -2 ).

Answer: [tex]a_{25} = 128[/tex]

Step-by-step explanation:

You need to use this formula:

[tex]a_n = a_1 + (n - 1)d[/tex]

Where [tex]a_n[/tex] is the nth] term,  [tex]a_1[/tex] is the first term,"n" is the term position and  "d" is the common diference.

You must find the value of "d". Substitute [tex]a_1=8[/tex], [tex]a_9=48[/tex] and [tex]n=9[/tex] into the formula and solve for "d":

[tex]48 = 8 + (9 - 1)d\\48=8+8d\\48-8=8d\\40=8d\\d=5[/tex]

Now, you can calculate the 25th term substituting into the formula these values:

[tex]a_1=8[/tex]

[tex]d=5[/tex] and [tex]n=25[/tex]

Then you get:

[tex]a_{25} = 8 + (25 - 1)5[/tex]

[tex]a_{25} = 8 + 120[/tex]

[tex]a_{25} = 128[/tex]

Answer:

210.6 cm

Step-by-step explanation:

Given that a piece of ribbon is cut into two shorter pieces in the ratio 2.8:1.25.

So that means length of the first smaller piece = 2.8x

and length of the second smaller piece = 1.25x

Then difference between their lengths = 2.8x-1.25x = 1.55x

Given that difference is equal to 80.6 centimeters then we get

1.55x=80.6

or x= 80.6/1.55

or x=52

then length of the original piece = 2.8x+1.25x

= 2.8*52+1.25*52

= 145.6+65

= 210.6 cm

Answer:

$930

Step-by-step explanation:

The amount payable at maturity of the loan is simply the sum of the loan amount and the fee charged on the loan.

The loan amount is 890 while the fee charged on the loan is 40. The amount repayable at maturity is thus;

890 + 40 = 930.

Therefore, he has to pay $930 by the time the loan reaches maturity.

Answer:

$930

Step-by-step explanation:

Daryl took out a single payment loan for $890.

That charged a $40 fee.

He takes loan of $890 that charged a $40 fee for a single time, so his maturity amount = loan amount + fees of $40

He have to pay by the time the loan reaches maturity = 890 + 40

                                                                                         = $930

He have to pay $930 by the time of maturity.

as a single logarithm.

Use the power rule to rewrite the middle term:

[tex]n \: ln(a) = ln( {a}^{n} ) [/tex]

[tex]ln(2x) + ln( {x}^{2} ) - ln(3y) [/tex]

Use the product rule to obtain:

Answer:

Car B

Step-by-step explanation:

Car B's price changes by the greatest amount (£40) when rounded to the nearest £100 among the three cars.

To determine which price changes by the greatest amount when rounded to the nearest £100, let's first calculate the rounded prices for each car:

Car A: £12380 rounds to £12400

Car B: £16760 rounds to £16800

Car C: £14580 rounds to £14600

Now, let's compare the differences between the original prices and the rounded prices:

- For Car A: £12400 - £12380 = £20

- For Car B: £16800 - £16760 = £40

- For Car C: £14600 - £14580 = £20

The greatest difference is £40, which occurs for Car B. Therefore, the price of Car B changes by the greatest amount when rounded to the nearest £100.

Answer:

[tex]c=\frac{99}{32}[/tex]

Step-by-step explanation:

The given quadratic equation is [tex]2x^2-5x+c=0[/tex].

Comparing this equation to:  [tex]ax^2+bx+c=0[/tex], we have a=2,b=-5.

Where: [tex]x_1+x_2=\frac{5}{2}[/tex] and [tex]x_1x_2=\frac{c}{2}[/tex]

The difference in roots is given by:

[tex]x_2-x_1=\sqrt{(x_1+x_2)^2-4x_1x_2}[/tex]

[tex]\implies 0.25=\sqrt{(2.5)^2-4(\frac{c}{2})}[/tex]

[tex]\implies 0.25^2=6.25-2c[/tex]

[tex]\implies 0.0625-6.25=-2c[/tex]

[tex]\implies -6.1875=-2c[/tex]

Divide both sides by -2

[tex]c=\frac{99}{32}[/tex]

Answer:

The value of c is 3.09375.

Step-by-step explanation:

Given : The difference between the roots of the equation [tex]2x^2-5x+c=0[/tex] is 0.25.

To find : The value of c?

Solution :

The general quadratic equation is [tex]ax^2+bx+c=0[/tex] with roots [tex]\alpha,\beta[/tex]

The sum of roots is [tex]\alpha+\beta=-\frac{b}{a}[/tex]

The product of roots is [tex]\alpha\beta=\frac{c}{a}[/tex]

On comparing with given equation, a=2, b=-5 and c=c

Substitute the values,

The sum of roots is [tex]\alpha+\beta=-\frac{-5}{2}[/tex]

[tex]\alpha+\beta=\frac{5}{2}[/tex] .....(1)

The product of roots is [tex]\alpha\beta=\frac{c}{2}[/tex] ....(2)

The difference between roots are [tex]\alpha-\beta=0.25[/tex] .....(3)

Using identity,

[tex]\alpha-\beta=\sqrt{(\alpha+\beta)^2-4\alpha\beta}[/tex]

Substitute the value in the identity,

[tex]0.25=\sqrt{(\frac{5}{2})^2-4(\frac{c}{2})}[/tex]

[tex]0.25=\sqrt{\frac{25}{4}-2c}[/tex]

[tex]0.25=\sqrt{\frac{25-8c}{4}}[/tex]

[tex]0.25\times 2=\sqrt{25-8c}[/tex]

[tex]0.5=\sqrt{25-8c}[/tex]

Squaring both side,

[tex]0.5^2=25-8c[/tex]

[tex]0.25=25-8c[/tex]

[tex]8c=25-0.25[/tex]

[tex]8c=24.75[/tex]

[tex]c=\frac{24.75}{8}[/tex]

[tex]c=3.09375[/tex]

Therefore, the value of c is 3.09375.

The volume of a sports ball with a diameter of 29 cm can be calculated using the formula for the volume of a sphere, resulting in approximately 12,719 cubic centimeters for its volume.

The volume of a sphere (such as a sports ball) can be determined using the formula V = 4/3πr³, where V represents volume and r represents the radius of the sphere. In the situation you described, the sports ball has a diameter of 29 cm which means the radius (r) is half of that or 14.5 cm. Plugging these values into the formula gives us:

V = 4/3π(14.5)³ ≈ 12,718.951 cm³

So, the volume of the sports ball is approximately 12,719 cubic centimeters.

Answer:

Each burrito platter costs $_31_ and each taco platter costs $_23__ .

Step-by-step explanation:

Let's first express both orders into equations.  Let's simply use b for the burritos platters and t for the tacos platters:

4b + 5t = 239

3b + 5t = 208

We can use the subtraction method easily on this one:

4b + 5t = 239

-

3b + 5t = 208

==============

1b + 0t = 31

b = 31

So, the burrito platters ost $31 each.

Now, let's find how much are the tacos ones.  Just take the first equation:

4(31) + 5t = 239

124 + 5t = 239

5t = 115

t = 23

Taco platters cost $23.

Let's test that with the second equation:

3b + 5t = 208

3(31) + 5(23) = 208

93 + 115 = 208

208 = 208

Verified!

The answer is $9.56.

Final answer:

The problem is a linear system where we find the cost of sugar cookie dough (x) at $12 per package and chocolate chip cookie dough (y) at $16 per package by forming and solving two linear equations.

Explanation:

The problem presented is one of linear systems, where we are asked to find the cost of one package of sugar cookie dough (x) and one package of chocolate chip cookie dough (y). To solve for x and y, we need to create two equations based on the information given:

13x + 6y = $252 (Lisa's sales)

8x + 12y = $288 (Julia's sales)

By solving this system of equations, we can determine the cost of each type of cookie dough. Using either substitution or elimination method will lead us to the solution. For this example, I'll use the elimination method:

Multiply each side of the first equation by 2, and the second equation by -1, and then add them together to eliminate y:
26x + 12y = $504
-8x - 12y = -$288
18x = $216
x = $216 / 18
x = $12

Substitute x back into any one of the original equations to find y:

13($12) + 6y = $252
$156 + 6y = $252
6y = $252 - $156
6y = $96
y = $96 / 6
y = $16

So the cost per package is $12 for sugar cookie dough and $16 for chocolate chip cookie dough.
