Answer:

x = ±4i or x = ±√-16

Step-by-step explanation:

x² - 5x + 19 = 5x + 3

x² + 16 = 0

x² = -16

x = ±√-16  (a negative square root is an imaginary number)

Answer:

Number of dimes = 28

Step-by-step explanation:

Given that:

Worth of coins = $6.30 = 6.30 * 100 = 630 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement;

x = 2y    Eqn 1

10x+25y = 630    Eqn 2

Putting x = 2y in Eqn 2

10(2y) + 25y = 630

20y + 25y = 630

45y = 630

Dividing both sides by 45

[tex]\frac{45y}{45}=\frac{630}{45}\\y=14[/tex]

Putting y=14 in Eqn 1

x = 2(14)

x = 28

Hence,

Number of dimes = 28

Answer:

y=x+4

Step-by-step explanation:

The slope of the graph is 1x or just x. The y-intercept of the graph is 4 because the line intercepts with the y axis at 4. So your equation is y=x+4.

Answer:

x = 19

Step-by-step explanation:

The shape of the flower base has six sides of equal lengths. This means that the flower base is a regular hexagon. A regular hexagon is a closed polygon with six equal sides and six equal angles.

Each side of the base measures x - 6, and the perimeter of the base is 78 units.

Length of each side = x - 6

The total length of the base = perimeter of the base.

The total length of the base is gotten by summing all the sides of the base. Since the base has 6 sides, therefore the total length of the base = 6(x - 6). Hence:

Perimeter of base = 6(x - 6)

78 = 6x - 36

6x = 78 + 36

6x = 114

x = 114 / 6

x = 19

Length of each side of base = x - 6 = 19 - 6 = 13 units

Answer:

x=260 texts

Step-by-step explanation:

85=0.25x+20

Subtract 20 from each side.

65=0.25x

Divide both sides by 0.25.

260=x

260 texts plus the $20 flat fee will cost $85.

Answer:

X = 5

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

The scale factor of this shape is of 4

From 12 to 3, you divide by 4

So now, you need to divide 20 by 4 to get what x is, and 20 ÷ 4 is 5

Answer:

The circumference of Dan's circle is approximately 50.27 inches.

Step-by-step explanation:

The length of the circumference ([tex]s[/tex]), measured in inches, is determined by the formula:

[tex]s = 2\pi\cdot r[/tex] (1)

Where [tex]r[/tex] is the radius, measured in inches.

If we know that [tex]r = 8\,in[/tex], then the length of the circumference is:

[tex]s = 2\pi\cdot (8\,in)[/tex]

[tex]s \approx 50.27\,in[/tex]

The circumference of Dan's circle is approximately 50.27 inches.

B got a 100 on my final

Step-by-step explanation:

The exponential function is given by N=4(2)ˣ

Exponent is a mathematical operation, written as an. Here the expression an involves two numbers, the base 'a and the exponent or power 'n'. Exponents are used to simplify algebraic expressions.

Given here: A particular type of cell doubles every hour and initially there were 4

let x be the number of hours then we have the exponential function

N= 4×2ˣ

Now for x=0 hours we have

N=4

which is the initial amount

similarly for x=1 we have

N=4×2

 =8 which is double from the initial amount in hour

Thus the function that can describe the relationship is N=4(2)ˣ

Answer:

Q2: slope = -½

Q3: slope = 1

Step-by-step explanation:

If the equation of the line is in the form y = mx+b, then m is the slope of the line and b is the y-intercept (the point where the line crosses the x-axis).

y = -½x, so the slope of the line is -½

y = x+15, so the slope of the line is 1
