Answer:

[tex]2x^{2}[/tex] - x + 5

Step-by-step explanation:

g(x)=x+1

f(x)=[tex]2x^{2}[/tex]-5x+8

f∅g(x)=2[tex](x+1)^{2}[/tex]-5(x+1) + 8

= 2([tex]x^{2}[/tex]+2x+1) - 5x - 5 + 8

= [tex]2x^{2}[/tex] +4x +2 - 5x +3

=[tex]2x^{2}[/tex] -x +5

Answer:

They are neither perpendicular nor parallel.

Step-by-step explanation:

Find the gradient of 2x + 6y = 42 by rearranging it in the form y = mx + c:

6y = -2x + 42

y = -(1/3)x + 7

The gradient is the co-efficient of x

Therefore the gradient is -(1/3)

The gradient of y = 2x - 1 is 2.

If they were parallel they would have the same gradient.

If they were perpendicular then the gradient of one would be the negative reciprocal of the other, e.g: if one was 2, the other would be -(1/2).

Neither of these are true, so they are neither perpendicular nor parallel.

The lines 3x+6y=42 and y=2x-1 are perpendicular

Two lines are parallel if they have equal slope

Two lines are perpendicular if the product of their slopes equals -1

The given lines are:

3x+6y=42 and y=2x-1

Rewrite each of the equations in the form y = mx + c

For line 3x + 6y = 42:

[tex]6y = -3x + 42\\\\y=\frac{-3}{6} x+\frac{42}{6}\\\\y=-0.5x+7[/tex]

The slope, m₁ = -0.5

For line y = 2x - 1

The slope, m₂ = 2

Since m₁ ≠ m₂, lines 3x+6y=42 and y=2x-1 are not parallel

m₁ m₂ = -0.5(2)

m₁ m₂ = -1

Since the product of the slopes equals -1, the lines 3x+6y=42 and y=2x-1 are perpendicular

Answer:

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Step-by-step explanation:

In order to solve this question we need to understand the following.

[tex]\sqrt{x}[/tex] = [tex]x^{\frac{1}{2} }[/tex]

[tex]\sqrt[3]{x} = x^{\frac{1}{3} }[/tex]

[tex]\sqrt[4]{x}= x^{\frac{1}{4} }[/tex]

(Notice that the numerator of the fraction is the power of the x that is being squared)

If you need proof here it is.....

[tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]

[tex](\sqrt{x} )^{2}[/tex] = [tex](x^{\frac{1}{2} } )^{2}[/tex]

x = x

Now that we got that out of the way we can rewrite [tex]\sqrt[7]{x^{3} }[/tex] as........

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Answer:

16xb

Step-by-step explanation:

In algebra the numbers are multiplied with the numbers and the variables are multiplied with the variables.

In this question we would multiply x with b and 4 with 4 .

Multiplying x with b would give xb and 4 with 4 gives 16

So the answer will be 16xb

For example if you have 3x and 10 z the answer would be 30xz

Answer:

g(-3) = [tex]\frac{17}{4}[/tex]

g(2) = -3

g(5) = [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

Let us solve the question

∵ g(x) = [tex]-\frac{3}{4}[/tex] x + 2, x ≠ 2

→ That means we can use it for any value os x except 2

∵ g(x) = -3, x = 2

→ That means we will use it only if x = 2

We want to find g(-3)

∵ x = -3 ⇒ ≠ 2

∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2

→ Substitute x by -3

∵ g(-3) = [tex]-\frac{3}{4}[/tex] (-3) + 2

∴ g(-3) = [tex]\frac{9}{4}[/tex] + 2

∴ g(-3) = [tex]\frac{17}{4}[/tex]

We want to find g(2)

∵ x = 2

∴ We will use g(x) = -3

→ This is a constant function which means g(2) equal to -3

∴ g(2) = -3

We want to find g(5)

∵ x = 5 ⇒ ≠ 2

∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2

→ Substitute x by 5

∵ g(5) = [tex]-\frac{3}{4}[/tex] (5) + 2

∴ g(5) = [tex]-\frac{15}{4}[/tex] + 2

∴ g(5) = [tex]-\frac{7}{4}[/tex]

Guy above me is wrong, it's actually D! Hope this helps.

Step-by-step explanation:

Answer:

(3, 1)

Step-by-step explanation:

Given the following constraints:

2x + 4y ≤ 10

x + 9y ≤ 12

x ≥ 0

y ≥ 0

We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.

From the graph, the following points satisfy the constraints:

(0,0), (3,1), (0,4/3), (5,0)

Given that:

P = x + 6y

For (0, 0): P = x + 6y = 0 + 6(0) = 0

For (3, 1): P = x + 6y = 3 + 6(1) = 9

For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8

For (5, 0) P = x + 6y = 5 + 6(0) = 5

Answer:

Answer:

60%

Step-by-step explanation:

Let the total number of people polled to vote be 1000

80% said they would vote for him

That is 800

20% said they would not vote for him

That is 200

Out of the 800, 70% actually voted

That will be ;

70/100 * 80 = 560

Also, 20% of the 200 that said they would not vote actually voted

That will be ;

20/100 * 200 = 40

Total is thus;

569 + 40 = 600

% is 600/1000 = 60%

Answer:

E) -4,7 and -2,8

Step-by-step explanation:

parallel lines have same slope

x - 2y = 16

y = 1/2 x -8 slope: 1/2

E. slope = Δy / Δx = (8-7) / (-2 - -4) = 1/2

Using the slope, it is found that the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.

----------------------

The equation of a line, in slope-intercept formula, is given by:

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

In which m is the slope.If two lines are parallel, they have the same slope.Given two points, the slope is given by change in y divided by change in x.

----------------------

The line given is:

[tex]x - 2y = 16[/tex]

In slope-intercept formula:

[tex]2y = x - 16[/tex]

[tex]y = \frac{x}{2} - 8[/tex]

----------------------

In this question, we want a line with an slope of 1/2.

At option E, the points are (-4,7) and (-2,8), thus, the slope is:

[tex]m = \frac{8 - 7}{-2 - (-4)} = \frac{1}{-2 + 4} = \frac{1}{2}[/tex]

Thus, the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.

Step-by-step explanation:

Answer:

x = 22, y = -4

Step-by-step explanation:

x + 6y = -2 --- Equation 1

-x = 3y - 10 --- Equation 2

Equation 2 ×(-1): x = -3y + 10 --- Equation 3

Substitute x = -3y + 10 into Equation 1:

x + 6y = -2

-3y + 10 + 6y = -2

3y + 10 = -2

3y = -2-10

= -12

y = -12 ÷ 3

y = -4

Substitute y = -4 into Equation 3:

x = -3y + 10

x = -3(-4) + 10

= 12 + 10

x = 22
