Answer:

Options A, C and E are correct.

Step-by-step explanation:

a. Assign two variables for the unknowns.- Firstly we read the problem and then assign values like (x and y) to the unknown entities.

c. Write two equations using the assigned variables. - After the first step, we get few equations to be solved. These equations are based on the assigned values from step 1.

e. Solve the pair of equations. - Finally we solve these equations to get the variable values.

The vertex of the parabola below is at the point (1, 3), and the point (2, 6) is on the parabola. What is the equation of the pa

lbvjy [14]

Easily we can use formula y=(x-h)^2 +k

as equation of a parabola if vertex was (h,k):

Y=(x-1)^2 + 3

and maybe node (2,6) is incorrect for this vertex of a parabola!!!

What is the 6th term of the geometric sequence 4, −20, 100, ...?

shtirl [24]

Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />

5. What is the solution to the equation -2.5(x-4)=-3x+4?

lana66690 [7]

Answer:

x = -12

Step-by-step explanation:

-2.5(x-4)=-3x+4

Distribute

-2.5x +10 = -3x +4

Add 3x to each side

-2.5x+10 +3x = -3x+4+3x

.5x +10 = 4

Subtract 10 from each side

.5x+10-10=4-10

.5x = -6

Divide by .5

.5x/.5 = -6/.5

x = -12

If you vertically compress the square root parent function f(x) = ^x, by 1/2 of a unit what is the equation of the new function

Naddik [55]

Answer:

The equation of the new function is $g(x) = \frac{\sqrt{x}}{2}$

Step-by-step explanation:

Suppose we have a function f(x).

a*f(x), a > 1, is vertically stretching f(x) a units. Otherwise, if a < 1, we are vertically compressing f(x) by a units.

f(x - a) is shifting f(x) a units to the right.

f(x + a) is shifting f(x) a units to the left

In this question:

$f(x) = \sqrt{x}$

Vertically compressing by 1/2:

This is the same as multiplying the function by 1/2. So

$\frac{1}{2} \times \sqrt{x} = \frac{\sqrt{x}}{2}$

The equation of the new function is $g(x) = \frac{\sqrt{x}}{2}$

4) Given the line with equation 2x + 5y= 10 :

Svetlanka [38]

A. <span>2x + 5y= 10
5y= -2x+10
</span>-> y= -2/5x+2

b. The slope is 2

c. For the y intecpet, x is always 0

y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2

(0,2) is the y-interecpt
