f(x) = 3x - 12

f(2) = 3(2) - 12

= 6 - 12

= -6

Answer:

The answer is -6

Step-by-step explanation:

f(x) = 3x - 12; f(2)

f(2) = 3x - 12

f(2) = 3(2) - 12

f(2) = 6 - 12

f(2) = -6

Thus, The answer is -6

Answer:

  29

Step-by-step explanation:

We can use ...

  (a +b +c)² = a² +b² +c² +2(ab +bc +ca)

  9² = a² +b² +c² +2(26)

  a² +b² +c² = 81 -52 = 29

Step-by-step explanation:

We know the formula:

(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)

Given:

a+b+c = 9 & ab+bc+ca = 26

Now putting the values in the above formula,

We get,

(9)² = a² + b² + c² + 2×26

81 = (a² +b² +c²) + 52

(a² +b²+c²) = 81-52

(a² + b² + c²) = 29 (Answer)

Answer:

129 cm

Step-by-step explanation:

The total height of all the people: 150 × 4 = 600 cm

The total height of Sally, Jackson and Tina: 145 × 3 = 435 cm

David’s height: 600 – 435 = 165 cm

Tina’s height: 165 + 5 = 170 cm

Jackson’s height: 170 × 4/5 = 136 cm

Therefore, Sally’s height: 600 – 165 – 170 – 136 = 129 cm

Thenks and mark me brainliest :))

The height of Sally will be 133 centimeters and the height of Jackson is 132cm.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The average height of Sally, Jackson, Tina, and David is 150 cm per person. Then the equation is given as,

(S + J + T + D) / 4 = 150

S + J + T + D = 600  ...1

The average height of Sally, Jackson, and Tina is 145 cm per person. Then the equation will be

(S + J + T) / 3 = 145

S + J + T = 435      ...2

Tina is 5 cm taller than David. Then the equation will be

T = D + 5  ...3

Jackson is 4/5 as tall as David. Then the equation will be

J = (4/5)D    ...4

From equations, 1 and 2, then we have

435 + D = 600

D = 165 cm

From equation 4, then we have

J = (4/5) x 165

J = 132 cm

From equation 3, then we have

T = 165 + 5

T = 170 cm

From equation 2, then we have

S + 132 + 170 = 435

S = 133 cm

The height of Sally will be 133 centimeters.

Answer:

A right-tailed test should be used to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.

Step-by-step explanation:

Type of procedure:

We want to test if the breaking strength is greater than a value, which means that the type of procedure used to solve this question is a right-tailed test, which is when we find the probability of having a mean higher than the sample mean found.

Other types of procedures:

Not related to this question speficially, but to similar problems.

To test if a measure is less than another measure, the procedure used is a left-tailed test.

To test if a measure is different from another measure, the procedure used is a two-tailed test.

Answer:

227.5 grams

Step-by-step explanation:

We know that a single 10p coin weights 6.5 g

Now we want to find the weight of a bag of 10p coins, such that the net value is £3.50  (where the weight of the bag is neglected)

The value of a 10p coin is £0.10

So the first thing we need to find, is how many coins there are in the bag.

To find that, we need to find the quotient between the total value and the value of a single coin:

£3.50/£0.10 = 35

So in the bag, we have 35 coins, and each one of them weighs 6.5 grams

Then the total weight is 35 times 6.5 grams:

35*6.5 g= 227.5 grams

1436 in³

Step-by-step explanation:

volume of sphere = 4/3πr³ = 4/3(3.14)(7³) =1436 in³

Answer:

1437 in³

Step-by-step explanation:

The formula of volume of sphere

= [tex] \frac{4}{3} \pi {r}^{3} [/tex]

The volume of the ball

[tex] = \frac{4}{3} \times \pi \times {7}^{3} [/tex]

[tex] = 1436.75504...[/tex]

= 1437 in³ (rounded to the nearest whole number)

Answer:

128√5/3 mm³

Step-by-step explanation:

Since we are not told what to find, we can as well look for the volume of the pyramid

Volume of a square pyramid: V = (1/3)a²h

a is the side length of the square

h is the height of the pyramid

Given

a = 8mm

l² = (a/2)² + h²

l² = (a/2)² + h²

6² = (8/2)² + h²

h² = 6² - 4²

h² = 36 - 16

h² = 20

h = √20

Volume of a square pyramid =  (1/3)*8²*√20

Volume of a square pyramid = 1/3 * 64 * 2√5

Volume of a square pyramid = 128√5/3 mm³

Answer:

The length of XY is 35.

Step-by-step explanation:

Since triangle FGH is similar to triangle XYZ, that means their sides are proportional to each other. FH corresponds to XZ, GH corresponds to YZ, and FG corresponds to XY. When dividing the corresponding length of triangle XYZ to the corresponding sides of triangle FGH, both [tex]\frac{10}{4}[/tex] and [tex]\frac{40}{16}[/tex] equals 2.5, so the side XY divided by 14 will also equal 2.5. To find the length of XY, multiply 14 by 2.5 and you'll get that the length of side XY is equal to 35.

Answer: x = -30

Step-by-step explanation:

y = -20 by using process of elimination substitute y as -20 in either of the equations you get -30 for x

The solution to the system of equations is x = 390 and y = 50. The value of x is equal to 390.

To find the value of x, solve the system of equations using the method of  substitution . Let's use the method of elimination:

Given equations:

x - 12y = -210                      (1)

x - 6y = 90                          (2)

To eliminate x, we can subtract equation 2 from equation 1:

(x - 12y) - (x - 6y) = (-210) - 90

Simplifying the equation:

x - 12y - x + 6y = -210 - 90

-6y = -300

Divide both sides of the equation by -6:

y = -300 / -6

y = 50

Now, substitute the value of y back into either equation:

x - 6(50) = 90

Simplify the equation:

x - 300 = 90

Add 300 to both sides of the equation:

x = 90 + 300

x = 390

Therefore, the solution to the system of equations is x = 390 and y = 50.

  11. axis of symmetry: x=4; vertex: (4, 4); domain: all real numbers; range: y ≤ 4

  12. x = -4, -2

Step-by-step explanation:

10. Your graph is substantially correct. (You might do yourself a favor by adding points ±1 either side of the vertex. This will help to make the graph more rounded near the bottom.) The red graph in the attachment is the graph of this function.

__

11. The vertex form of this equation is ...

  f(x) = -(x² -8x) -12 = -(x² -8x +16) -12 +16

  f(x) = -(x -4)² +4

This tells you the vertex is (4, 4). The axis of symmetry is the vertical line through the vertex, so is x=4. The domain of all polynomial functions is "all real numbers." This has a maximum at y=4, so the range is y ≤ 4.

__

12. The vertex form of this equation is ...

  f(x) = (x +3)² -1

so the vertex is (-3, -1). Points at x = -3 ± 1 will be the x-intercepts, so the solutions to the equation f(x) = 0. The graph of it is the green graph in the attachment.

Answer:

[tex] (A)\displaystyle \begin{array} {ccc} \displaystyle y = - 2 \\ x - 2y = 6\\ \end{array} [/tex]

Step-by-step explanation:

since the line is horizontal and passes -2 the equation of the blue line should be

[tex] \displaystyle \large y = - 2[/tex]

remember The form of equation of a line

[tex] \displaystyle \boxed{ \displaystyle y = mx + b}[/tex]

where m is slope of the line and b is the y-intercept we can clearly see that the red line crosses y-axis at (0,-3) therefore b=-3

to figure out m we can consider the following formula:

[tex] \displaystyle m = \frac{ \Delta y}{ \Delta x} [/tex]

from the graph we acquire ∆y=1 and ∆x=2

thus substitute:

[tex] \displaystyle m = \frac{ 1}{ 2} [/tex]

so we have figured out m and b

therefore our equation of blue line is

[tex] \displaystyle y = \frac{1}{2} x - 3[/tex]

our given options are in standard form so

move -3 to left hand side and change its sign:

[tex] \displaystyle y + 3= \frac{1}{2} x [/tex]

cross multiplication:

[tex] \displaystyle 2y + 6= x[/tex]

move 6 to right hand side and x to left hand side and change its sign

[tex] \displaystyle - x + 2y = - 6[/tex]

multiply both sides by -1:

[tex] \displaystyle x - 2y = 6[/tex]

hence, our system of linear equation is

[tex] \displaystyle \begin{cases} \displaystyle y = - 2 \\ x - 2y = 6\\ \end{cases}[/tex]
