Hi there.

The answer is f(0) = 3.

Explanation:

Given 2 functions with given domains.

[tex]f(x) = 5x - 1[/tex]

where x < -2

[tex]f(x) = x + 3[/tex]

where x >= -2

Evaluate the value of f(x) when x = 0. Therefore, f(x)= 5x-1 cannot be used as the given x = 0 is greater than its domain.

Thus, our main function is f(x) = x+3

Evaluate the value by substituting x = 0 in the function.

[tex]f(0) = 0 + 3 \\ f(0) = 3[/tex]

Thus, the answer is f(0) = 3

The answer is option D.

Answer:

1 Quarter, 1 Dime, 1 Nickel, a 2 Pennies

Step-by-step explanation:

x+ 0.36=0.78

x=0.42

So, 1 Quarter,  1 Dime, 1 Nickel, and 2 Pennies

0.25 + 0.10+ 0.05+ 0.02= 0.42

0.42 + 0.36 equals 0.78

The transformation is (4, 3)

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation

If the there is rotation of 90° around the origin (0,0), that can be expressed as

(x, y) => (-y, x)

Which means a 90° rotation that can done by changing coordinates positions and inverting the sign of y-coordinate.

However, the problem is giving the transformed coordinates where

Q'(–3, 4)

Hence, the transformation is (4, 3)

Answer:

The answer is 6/77

Step-by-step explanation:

Answer:

a₄ = - [tex]\frac{27}{2}[/tex]

Step-by-step explanation:

In a geometric sequence, the common ratio r is calculated as

r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{a_{3} }{a_{2} }[/tex] , substitute values

[tex]\frac{2x+2}{x}[/tex] = [tex]\frac{3x+3}{2x+2}[/tex] ( cross- multiply )

(2x + 2)² = x(3x + 3) ← expand both sides

4x² + 8x + 4 = 3x² + 3x ( subtract 3x² + 3x from both sides )

x² + 5x + 4 = 0 ← in standard form

(x + 1)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 4 = 0 ⇒ x = - 4

However x ≠ - 1 as this would make the denominator of the second term equal to zero and therefore undefined.

Thus x = - 4 and

r = [tex]\frac{2(-4)+2}{-4}[/tex] = [tex]\frac{-8+2}{-4}[/tex] = [tex]\frac{-6}{-4}[/tex] = [tex]\frac{3}{2}[/tex]

Then

a₁ = - 4

a₂ = - 4 × [tex]\frac{3}{2}[/tex] = - 6

a₃ = - 6 × [tex]\frac{3}{2}[/tex] = - 9

a₄ = - 9 × [tex]\frac{3}{2}[/tex] = - [tex]\frac{27}{2}[/tex]

Step-by-step explanation:

2x + y = 6/3

x+y = 1

x=1-y

now,

y=5-(-1)/2

y=3

again,

x=1-3

x=-2

therefore, x= -2 and y = 3

Answer:

The correct answer is: Option C: Standard Deviation

Step-by-step explanation:

In a dataset, there are several methods that are used to determine the attributes of the data. One of them is standard deviation.

Deviation is derived from the word "Deviate" which means to move far.

Standard deviation is used to measure the distance of a data value from the mean i.e. how far a data value is from mean.

Hence,

The correct answer is: Option C: Standard Deviation

Answer:

we conclude that the cost of 100 pencils = $11

Step-by-step explanation:

Brianna can buy 14 pencils for $1.50 at the school store.

so

unit rate =  $1.50 /  14 pencils

              = 0.11 USD per pencil

Thus,

The cost of 1 pencil =  $0.11

The cost of 100 pencils = $0.11 × 100

                                       = $11

Therefore, we conclude that the cost of 100 pencils = $11

Answer:

b.   b=50√c

Step-by-step explanation:

The equation can be used to find other combinations of b and c will be b = 50√c. Then the correct option is B.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The variable b varies directly as the square root of c.

b ∝ √c

If the proportionality sign is removed with the equal sign, then a constant (k) is introduced.

b = k√c

If b = 100 when c = 4.

Then the value of k will be

    100 = k√4

    100 = 2k

100 / 2 = k

        k = 50

Substitute the value of k in equation, then the equation will be

b = 50√c

The equation can be used to find other combinations of b and c will be b = 50√c.

Then the correct option is B.

Step-by-step explanation:

-3x+5y=-2

3x+7y=26

I will add the two equations to eliminate x

Answer:

19/25 metres

Step-by-step explanation:

From the question, we are given;

Total length of the string = 3 4/5 metres

If the string is cut into 5 equal size, the length of each piece will be expressed as;

Length of each piece = Total string length/5

Length of each piece = (3 4/5)/5

Length of each piece = 19/5 ÷ 5

Length of each piece = 19/5 ×1/5

Length of each piece = 19/25 metres

Hence the length of each piece she cut is 19/25 metres
