Solve and check
y = 3x - 10
y = 2x - 5

Answer:

answer is x=3 and y=5.... so it is (3,5)

Step-by-step explanation:

you want to combine them so y=3x-4 so subsitute y

-2x+5(3x-4)=19

-2x+15x-20=19

            +20   +20

13x=39

---    ---

13     13

x=3

now subsitute 3 into x into any problem...

3(3)-4=y

9-4=y

and 9-4 is 5 so it is...

(3,5)

Answer:

C, B

Step-by-step explanation:

Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.

The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

Answer:

4096

Step-by-step explanation:

Hey there!!!!

8  raised to the power of 4 = [tex]8^{4}[/tex]

[tex]8^{4}[/tex] = 8*8*8*8

if we multiply:

8*8=16

16*8= 128

128*8 = 4096

hope this helps :)

Answer:

5x?

Step-by-step explanation:

Answer:

= 5

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

1/4 = x/20

20 ⋅ 1/4 = 20 ⋅ /20

Simplify

= 5

Answer:

(2x8)+(3x10)

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

1/10(x + 130) = -2(3 - x)

x + 130 = -20(3-x)

x + 130 = -60 + 20x

x - 20x = -60 - 130

-19x = -190

x = 10

Given:

The cost of the T.V. for Colin = £ 800.

The rate of depreciation per year = 4%

Time period = 3 years

To find:

How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.

Solution:

To solve the above-given problem, we will use the following formula:

where

A = the final value after depreciation

P = the present value

R = rate of depreciation

n = time period

Now, on substituting the given values in the formula, we get

we will round the above answer to its nearest penny where appropriate

≈ £ 708

Thus, the worth of the t.v. in 3 years will be £ 708.

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

So, the computer actually cost the customer is $74,750.

Answer:

Step-by-step explanation:

the triangles are similar

so as we know

now let's solve it

according to the question

[tex] \frac{24}{30 } = \frac{x + 7}{2x - 10} [/tex]

[tex] \frac{4}{5} = \frac{x + 7}{2x - 10} [/tex]

[tex]4(2x - 10) = 5(x + 7) \: (cross \: multiplication)[/tex]

[tex]8x - 40 = 5x + 35[/tex]

[tex]8x - 5x = 35 + 40[/tex]

[tex]3x = 75[/tex]

[tex]x = 25[/tex]

Answer:

The acceleration of object is -4 ms⁻²

Step-by-step explanation:

We are given:

Initial Velocity = 65 m/s

Final Velocity = 25 m/s

Time t = 10 seconds

We need to find acceleration.

The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]

Putting value in the formula and finding acceleration:

[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]

So, acceleration of object is -4 ms⁻²

Ebony's brother is x + 4 years old.

Ebony's mum is 3x years old.

Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.

Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.

Answer:

Step-by-step explanation:

Find the complete question below;

Given the height modeled by the function;

h(t) = 5 + 98t-4.9t²

when t = 0

h(0) = 5 + 98(0)-4.9(0)²

h(0) = 5

when t = 5

h(5) = 5 + 98(5)-4.9(5)²

h(5) = 5 + 490 - 122.5

h(5) = 372.5

when t = 10

h(10) = 5 + 98(10)-4.9(10)²

h(10) = 5 + 980 - 490

h(10) = 495

when t = 15

h(15) = 5 + 98(15)-4.9(15)²

h(15) = 5 + 1470 - 1,102.5

h(15) = 372.5

when t = 20

h(10) = 5 + 98(20)-4.9(20)²

h(10) = 5 + 1960 - 4.9(400)

h(10) = 1965- 1960

h(10) = 5
