Write an equation of the line that is parallel to the line y = -x + 4 and passes through the points 0, 10.
yanalaym [24]
Line parallel to y = -x+4 will have the same gradient.
Gradient = -1
Equation of line: y = -x + c
Point : (0,10) replace in the above equation
y = -x + c
10 = -0 + c
c = 10
Equation is: y = -x + 10


Hope it helped!

It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.

Select the correct answer.
Nookie1986 [14]

Answer:

Correct option: C.

Step-by-step explanation:

(Assuming the correct function is R(x) = 2x^2 + 3x + 5)

To find the input value that gives the value of R(x) = 19, we just need to use this output value (R(x) = 19) in the equation and then find the value of x:

R(x) = 2x^2 + 3x + 5

19 = 2x^2 + 3x + 5

2x^2 + 3x -14 = 0

Solving this quadratic function using the Bhaskara's formula (a = 2, b = 3 and c = -14), we have:

\Delta = b^2 - 4ac = 9 + 112 = 121

x_1 = (-b + \sqrt{\Delta})/2a = (-3 + 11)/4 = 2

x_2 = (-b - \sqrt{\Delta})/2a = (-3 - 11)/4 = -3.5

So looking at the options, the input to the function is x = 2

Correct option: C.

Answer:

12

Step-by-step explanation:

\huge {c}^{ \frac{1}{2} }  +  {c}^{ \frac{1}{3} }  \\  \\ \huge =  {64}^{ \frac{1}{2} }  +  {64}^{ \frac{1}{3} } \\(plug \: c = 64)   \\  \\ \huge =  { ({8}^{2}) }^{ \frac{1}{2} }  +  {( {4}^{3} )}^{ \frac{1}{3} }   \\  \\  \huge =  {8}^{2 \times  \frac{1}{2} }  +  {4}^{3 \times  \frac{1}{3} }  \\  \\ \huge = 8 + 4 \\ \\ \huge = 12
