Answer 1

Answer:

The solution to the inequality is:

[tex]-1\le \:x\le \:3[/tex]

The line graph of the solution is also attached.

Step-by-step explanation:

Given the expression

[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]

solving the expression

[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]

[tex]\mathrm{If}\:a\le \:u\le \:b\:\mathrm{then}\:a\le \:u\quad \mathrm{and}\quad \:u\le \:b[/tex]

[tex]4x-1\le \:5x\quad \mathrm{and}\quad \:5x\le \:3\left(x+2\right)[/tex]

solving

[tex]4x-1\le \:5x[/tex]

Add 1 to both sides

[tex]4x-1+1\le \:5x+1[/tex]

Simplify

[tex]4x\le \:5x+1[/tex]

Subtract 5x from both sides

[tex]4x-5x\le \:5x+1-5x[/tex]

simplify

[tex]-x\le \:1[/tex]

Multiply both sides by -1 (reverse inequality)

[tex]\left(-x\right)\left(-1\right)\ge \:1\cdot \left(-1\right)[/tex]

Simplify

[tex]x\ge \:-1[/tex]

Similarly solving

[tex]5x\le \:3\left(x+2\right)[/tex]

Subtract 3x from both sides

[tex]5x-3x\le \:3x+6-3x[/tex]

Simplify

[tex]2x\le \:6[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}\le \frac{6}{2}[/tex]

Simplify

[tex]x\le \:3[/tex]

So combine the interval

[tex]x\ge \:-1\quad \mathrm{and}\quad \:x\le \:3[/tex]

Merge overlapping intervals

[tex]-1\le \:x\le \:3[/tex]

Therefore, the solution to the inequality is:

[tex]-1\le \:x\le \:3[/tex]

The line graph of the solution is also attached.

Step-by-step explanation:

The domain refers to the x values used in the equation/graph. The line appears to go from -10 to 10 on the x-axis. The dots above -10 and 10 are not shaded in meaning those x values do not count towards the domain meaning we will use parenthesis instead of brackets for interval notation or no equal to signs in inequality notation.

Interval Notation: (-10, 10)

Inequality Notation: -10 < x < 10

The cost of a mobile phone processor is directly proportional to its speed.

A 2GHz mobile costs £500.

Let x be the speed of a processor in GHz

Let y be the cost in pounds.

Find a formula linking the variables.

Answers

Answer: See explanation

Step-by-step explanation:

We are going to use the formula used in calculating direct proportion which is equal to:

y = kx

where,

x = speed of a processor in GHz

y = the cost in pounds

Therefore, y = kx

500 = 2k

Therefore, y = 2k

transforming quadratic graphs

Answers

Answer:

f(x) = 3(x - 2)² + 4

f(x) = 3x² - 12x + 16

Step-by-step explanation:

Vertex form of a parabola:

y = a(x - h)² + k

Standard form of a parabola:

y = ax² + bx + c

Let's find the vertex of this parabola.

(h, k) → (2, 4)

In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.

Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.

7 = a[(3) - (2)]² + 4

Simplify using PEMDAS.

7 = a(1)² + 47 = a + 4

Subtract 4 from both sides.

a = 3

Now we have (h, k) and a of the vertex form.

y = a(x - h)² + k → y = 3(x - 2)² + 4

In order to convert from vertex to standard form, simplify the equation by FOILing.

y = 3(x - 2)² + 4y = 3(x² - 4x + 4) + 4

Distribute 3 inside the parentheses.

y = 3x² - 12x + 12 + 4

Combine like terms.

y = 3x² - 12x + 16

Therefore, we have the answer:

Vertex form:

f(x) = 3(x - 2)² + 4

Standard form:

f(x) = 3x² - 12x + 16
