Answer:

the graph is shifted up 9, compressed by a factor of 2

Step-by-step explanation:

General form of an absolute value equation:

f(x)= a|x - h| + k

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h tell us how far the graph shifts horizontally and vertically.

parent function f(x) = |x|,  

the translation of the function g(x) = 2|x| + 9 from the parent function.

- the +9 shift the graph up 9

- the 2 compresses the graph

Answer:

1 kg of mushrooms costs £2.7.

Step-by-step explanation:

Step 1: Write equations.

Let a be the cost of apples per kg and m the cost of mushrooms per kg.

First equation: Ibrar buys 3 kg of apples. He also buys 0.4 kg of mushrooms. The total cost is £6.93.

[tex]3a + 0.4m = 6.93[/tex]

Second equation: 1 kg of apples cost £1.95.

[tex]a = 1.95[/tex]

Step 2: Solve the system of equations.

1) [tex]3a + 0.4m = 6.93[/tex]

2) [tex]a = 1.95[/tex]

Substitute a in the first equation with a from second.

[tex]3a + 0.4m = 6.93\\3(1.95) + 0.4m = 6.93[/tex]

Solve for m.

[tex]5.85 + 0.4m = 6.93\\0.4m = 6.93 - 5.85 \\0.4m = 1.08\\m = \frac{1.08}{0.4}\\m = \text{\£}2.7[/tex]

The cost of 1 kg of mushrooms is £2.7.

Two or more expressions with an Equal sign is called as Equation.

Given that Ibrar buys 3kg of apples

Ibrar buys 0.4kg of mushrooms.

The total cost is £6.93

3x+0.4y=6.93...(*)

1kg of apples cost is £1.95

x=1.95

Substitute the value of x in *

3(1.95)+0.4y=6.93

5.85+0.4y=6.93

Subtract 5.85 on both sides

0.4y=6.93-5.85

0.4y=1.08

Divide both sides by 0.4

y=2.7

Hence, the cost of 1 kg of mushrooms is £2.7.

Answer:

Multiply to remove the fraction, then set equal to 0 and solve.

Exact Form: y = − 1/10

Decimal Form: y = − 0.1

Step-by-step explanation:

Answer:

y = -1/10 or -0.1

Step-by-step explanation:

Multiply both sides of the equation by 100.

To find the opposite of 5y−17, find the opposite of each term.

The opposite of −17 is 17.

Combine 155y and −5y to get 150y.

Subtract 17 from both sides.

Subtract 17 from 2 to get −15.

Divide both sides by 150.

​Reduce the fraction  

​ to lowest terms by extracting and canceling out 15.

An equation is formed of two equal expressions. The cost of a new book is $7.43, while the cost of an old book is $8.86.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of 14 used books is $124. Therefore, the cost of a single used book is,

Cost of single used book(u) = 124/14 = $8.86

Also, the cost of 12 used books and 4 new books is $136. Therefore, the equation can be written as,

12u + 4n = 136

12(8.85) + 4n = 136

106.2 + 4n = 136

n = $7.43

Hence, the cost of a new book is $7.43, while the cost of an old book is $8.86.

The form of this root is a "mirror image" of the root that is given. They come in pairs.

So the exact value of the other root is

x = - 2 + √6

You should be very careful looking at this root. The only  difference is the plus sign where the minus sign used to be.

The given root has to be of the form a rational number ± an irrational number.

Later on, when you get into higher math classes, you will find there is another kind of number that this same rule applies to.

Answer:

it's estimated that 750 students in the whole school dislike the 8:30am start time.

Step-by-step explanation:

Since 30 of the 40 students said "no", it means 30/40, or 3/4 of the random sample disliked the 8:30am start time. Multiply this by the whole population: 1,000 × (3/4) = 750.

Another way to check this is using 10/40 = .25 and doing 1000x.25 = 250 (the amount of students who liked it). Then subtract from whole population and it's 750.

Answer:

△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.

Step-by-step explanation:

If L' were (-3,-4), it would be a reflection of L across the x-axis as J' and K' are with respect to J and K. Unfortunately, because it is not, the side lengths J'L' and K'L' of triangle J'K'L' are different from those of triangle JKL. This ensures the triangles JKL and J'K'L' are not congruent.

If the average rate of change is 18, then the value of the x is √(13/5). Then the correct option is B.

It's an average of how far the functions changed per unit throughout that time period.

Let f be the function given by f(x) = x³ + 5x.

Then the value in the closed interval [1,3] will be

The instantaneous rate of change will be

[tex]f'(x) = 3x ^2 + 5[/tex]

Then the average rate of change will be

[tex]= \dfrac{f(3) - f(1)}{3-1} \\\\= \dfrac{(3^3 + 5\times 3) - (1^3 + 5 \times 1)}{3-1}\\\\= 18[/tex]

Then we have

3x² + 5 = 18

Then the value of x will be

[tex]\begin{aligned} \rm 3x^2 + 5 &= 18\\\\\rm x &= \sqrt{\dfrac{13}{3}} \end{aligned}[/tex]
