Answer:

c

Step-by-step explanation:

ax - ay - bx + by ( factor a out of the 1st 2 terms and - b out of the last 2 terms )

= a(x - y) - b(x - y) ← factor out (x - y) from each term

= (a - b)(x - y)

Collinear points are points on the same line

The value of DE is 39

The given parameters are:

AB = 2x + 4

BC= 3x -12

CD = 2x + 4

DE = 5x -21

AE = 119

The length AE is calculated as:

AE = AB  + BC + CD + DE

So, we have:

119 = 2x + 4 + 3x - 12 + 2x + 4 + 5x - 21

Collect like terms

2x + 3x + 2x + 5x = 119 - 4 + 12 - 4 + 21

12x = 144

Divide both sides by 12

x = 12

Recall that:

DE = 5x -21

So, we have:

DE = 5 * 12 -21

DE = 39

Hence, the value of DE is 39

Step-by-step explanation:

The table when completed looks like this:

x -2 -1 0 1 2

f(x) 4 2 1 2 4.

The graph is provided in the attachment.

A function is a relation between a dependent variable (say f(x) ) and an expression of an independent variable (say x), used to determine the value of a dependent variable from a given value of an independent variable.

We have been given a function,

[tex]f(x) = \left \{ {{\frac{1}{2}^{x} , x \leq 0} \atop {2^{x}, x > 0 }} \right.[/tex]

We are asked to determine the value of f(x) when x = {-2, -1, 0, 1, 2}

For  the values of x ≤ 0, we will take f(x) = (1/2)ˣ.

∴ f(-2) = (1/2)⁻² = 2² = 4

f(-1) = (1/2)⁻¹ = 2¹ = 2

f(0) = (1/2)⁰ = 1

Now, for the values of x > 0, we take f(x) = 2ˣ

∴ f(1) = 2¹ = 2

f(2) = 2² = 4

We can design the table now as

x -2 -1 0 1 2

f(x) 4 2 1 2 4.

We plot these points on the graph: (-2, 4), (-1, 2), (0, 1), (1, 2), (2, 4).

The graph is attached.

Answer:

Step-by-step explanation:

In this math, we will be using the law of cosine.

a2 = b2 + c2 − 2bc cosA

This is to note that a here is actually x

a= x

b = 10

c = 9.4

cosA = cos20°

[tex]a = \sqrt{b^{2} +c^{2} - (2bc*cosA) }\\\\a= \sqrt{100 +88.36 - (188- 0.94)} \\\\a = \sqrt{1.3}\\\\a = 1.14[/tex]

Answer:

Five and twenty six twenty eighths.

Step-by-step explanation:

Start with writing the fractions in numbers:

[tex]2\frac{3}{7} +3\frac{2}{4}[/tex]

The 2 next to the first fraction is considered a whole number therefore we can say:

[tex]\frac{2}{1} *\frac{7}{7} =\frac{14}{7}[/tex] then,  [tex]\frac{14}{7} + \frac{3}{7} =\frac{17}{7}[/tex]

[tex]2\frac{3}{7} =\frac{17}{7}[/tex]

The 3 is also considered a whole number therefore:

[tex]\frac{3}{1} *\frac{4}{4} =\frac{12}{4}[/tex] then, [tex]\frac{12}{4} +\frac{2}{4} =\frac{14}{4}[/tex]

[tex]3\frac{2}{4} =\frac{14}{4}[/tex]

We got our 2 fractions without whole numbers now which makes it easier to add them up however they have different denominators meaning we can't add them.

[tex]\frac{17}{7} +\frac{14}{4}[/tex] not possible to add up.

We have to find a common factor, we will do this by looking at our times tables and realizing that 7x4= 28 and 4*7= 28. This will ensure both dominators are the same.

[tex]\frac{17}{7} *\frac{4}{4} =\frac{68}{28}[/tex]

[tex]\frac{14}{4} *\frac{7}{7} =\frac{98}{28}[/tex]

Now we got both fractions with equal denominators which means we can add them up as you would with normal numbers:

[tex]\frac{68}{28} +\frac{98}{28} =\frac{166}{28}[/tex]

We need to make sure to simplify the resultant fraction now, we know that 28*5= 140 and 28*6= 168, we will use 5 as our whole unit since it fits (168 is greater than 166 therefore we can't use that):

[tex]\frac{166}{28} =5\frac{26}{28}[/tex] (this is the answer on the answer choices)

Now just simplify 26 over 28:

[tex]5\frac{26}{28}=5\frac{13}{14}[/tex]

This gives us our final answer of 5 and thirteen fourteenths however judging from the answer choices our answer will be five and twenty six twenty eighths.

Answer:

x = 1 , y = 4

Step-by-step explanation:

3x = y + 1

=> y + 1 = 3x

=> y = 3x - 1

y = 3 + x

Substituting y = 3x + 1 in y = 3 + x,

=> 3x + 1 = 3 + x

=> 3x - x = 3 - 1

=> 2x = 2

=> x = 2/2

=> x = 1

y = 3 + x

Substituting x = 1,

=> y = 3 + 1

=> y = 4

Answer:

x=2

y=5

Step-by-step explanation:

y=3x

replace it in 3x=y+1

so"

3x= 3+x+1

3x-x=4

2x=4

x=2

so now we replace x=2 in y=3+x

which gives:

y=3+2

y=5
