Answer:

➨ f(-1) = 0

Step-by-step explanation:

➨ Look at the table and compare.

Notice that when x = -1, f(x) = 0

f(-1) is like substituting x = -1 and get the f(x) value at x = -1.

Thus, f(-1) = 0

Answer:

28

Step-by-step explanation:

-3 * (x-11) = -51

x-11 = 17

x = 28

The line perpendicular to the line y = 2/3x + 4 is 4) y = -3/2x + 4.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

The given equation of a line in slope-intercept form is y = (2/3)x + 4.

Now, We know lines perpendicular to each other have slopes that are negative reciprocal to each other.

If one line has a slope of 'm' the line perpendicular to it will have slope

(-1/m).

Therefore, From the given options the line y = -(3/2)x + 4 is the line perpendicular to the line y = (2/3)x + 4.

Answer:

[tex]M = (9,3)[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (4,8)[/tex]

[tex](x_2,y_2) = (14,-2)[/tex]

Required

Find the midpoint (M)

The midpoint is calculated as follows:

[tex]M = (\frac{1}{2}(x_1+x_2),\frac{1}{2}(y_1+y_2))[/tex]

Substitute values for x's and y's

[tex]M = (\frac{1}{2}(4+14),\frac{1}{2}(8-2))[/tex]

[tex]M = (\frac{1}{2}(18),\frac{1}{2}(6))[/tex]

[tex]M = (\frac{1}{2}*18,\frac{1}{2}*6)[/tex]

[tex]M = (9,3)[/tex]

Hence, the midpoint is (9,3)

Answer:

Option A

Step-by-step explanation:

Weight of an apple = twice of the weight of a lemon

Weight of an apple = 2(weight of a lemon)

x = 2y ------(1)

x = weight of an apple

y = weight of a lemon

Number of apples in a box = 16

Weight of the apple box (A) = 16x

Number of lemons in another box = 24

Weight of the lemon box (B) = 24y

Therefore, [tex]\frac{A}{B}=\frac{16x}{24y}[/tex]

[tex]\frac{A}{B}=\frac{2x}{3y}[/tex]

[tex]\frac{A}{B}=\frac{2(2y)}{3y}[/tex] [From equation (1)]

[tex]\frac{A}{B}=\frac{4y}{3y}[/tex]

[tex]\frac{A}{B}=\frac{4}{3}[/tex]

Option A will be the correct option.

Answer:

Overall, the steps for algebraically finding the range of a function are:

1.Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

2.Find the domain of g(y), and this will be the range of f(x).

3.If you can't seem to solve for x, then try graphing the function to find the range.

Step-by-step explanation:

Answer:

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.

Given:

The equations are

[tex]5y=2x-5[/tex]

[tex]5y=4+3x[/tex]

[tex]5y-3x=-1[/tex]

To find:

The two parallel lines.

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Isolate variable y in each of the given equations, to get the slope intercept form of the lines.

The slope intercept forms of given lines are

[tex]y=\dfrac{2}{5}x-1[/tex]

[tex]y=\dfrac{4}{5}+\dfrac{3}{5}x[/tex]

[tex]y=-\dfrac{1}{5}+\dfrac{3}{5}x[/tex]

On comparing these equations with slope intercept form, we get

Slope of I line = [tex]\dfrac{2}{5}[/tex]

Slope of II line = [tex]\dfrac{3}{5}[/tex]

Slope of III line = [tex]\dfrac{3}{5}[/tex]

Slope of parallel lines are equal. So, lines II and III are parallel because their slopes are equal.

Therefore, the correct option is C.

Answer:

x =22

Step-by-step explanation:

The two angles are corresponding angles , so the angles are equal

x+14 = 5x-74

Subtract x from each side

x+14-x = 5x-x-74

14 = 4x-74

Add 74 to each side

14+74 = 4x-74+74

88 = 4x

Divide by 4

88/4 = 4x/4

Answer:

The foci of the given ellipse  = (0 ,-√5 ) and ( 0, √5 )

Step-by-step explanation:

Step(i):-

Given Ellipse   9 x² + 4 y² = 36

                     [tex]\frac{9x^{2} }{36} + \frac{4y^{2} }{36} =1[/tex]

               ⇒     [tex]\frac{x^{2} }{4} + \frac{y^{2} }{9} = 1[/tex]

Step(ii):-

  The Major axis lies on y-axis

   Foci of the Formula C² = a² -b² = 9-4 =5

                                 C = √5

The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre

Given ellipse of the foci is lie on Y- axis

Final answer:-

The foci of the given ellipse  = (0 ,-√5 ) and ( 0, √5 )

Step-by-step explanation:

Answer:

a) 2002 different groups of 5 problems can be chosen from the 14 problems.

b) P=0.04995%

c) 21 different groups of 5.

P=1.04895%

Step-by-step explanation:

a)

In order to solve this problem we must ask ourselves: Does the order matter? We can see that in this case the order in which the problems are chosen doesn't really matter, so we are talking about a combination:

[tex]_{n}C_{r}=\frac{n!}{r!(n-r)!}[/tex]

in this case, n=14 while r=5, so our combination will be:

[tex]_{14}C_{5}=\frac{14!}{5!(14-5)!}[/tex]

which yields:

[tex]_{14}C_{5}=2002[/tex] which will be the answer for part a.

b)

In order to find the probability we can use the probability formula:

[tex]Probability=\frac{desired \hspace{5}outcome}{number\hspace{5} of \hspace{5} possible \hspace{5} outcomes}[/tex]

so in this case there is only 1 desired outcome out of the 2002 possible outcomes so our probability is:

[tex]P=\frac{1}{2002}[/tex]

which is the same as:

P=0.04995%

c) The same applies to part c. In order to find the number of groups Silvia did, we can make us of the combination formula:

[tex]_{7}C_{5}=\frac{7!}{5!(7-5)!}[/tex]

which yields:

[tex]_{14}C_{5}=21[/tex]

so there are 21 different groups of 5 she did by solving 7 problems.

So we can use the same formula to find the probability that one of the groups she completed comprised the group selected to be graded so we get:

[tex]P=\frac{21}{2002}=\frac{3}{286}[/tex]

which is the same as:

P=1.04895%

(remember that in order to turn a decimal number into a percentage you need to multiply the decimal number by 100)
