Answer:

1 solution

Step-by-step explanation:

First, simplify the equation.

3x - 6 = 7x = 3x - 1

Then, combine like terms and isolate the variable.

7x = 5

Then, divide each side by 7.

x = 5/7.

"Given the coefficient values of a, b, and c, create a quadratic function g(x) in standard form. a=1, b=4, c= 3" Please Urgent I
jonny [76]

Answer:

g(x) = x^{2} + 4x + 3; x = -3, -1; g(x) = 3

Step-by-step explanation:

a) The standard form of a quadratic function is:

f(x) = ax^{2} + bx + c

Now, replace the variables with the values given.

g(x) = x^{2} + 4x + 3

b) To find the zeros of the function (x-intercepts), set y to 0 and solve for x:

g(x) = x^{2} + 4x + 3

0 = x^{2} + 4x + 3

(x + 3)(x + 1) = 0

(x + 3) = 0

x = -3

(x + 1) = 0

x = -1

c) To find the y-intercept of the function, set the x values to 0:

g(x) = x^{2} + 4x + 3

g(x) = 3

The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.
Sindrei [870]

Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.

Geometry- I need an answer for x and y.
elixir [45]

Answer:

x = 13sqrt(3) ft = 22.5 ft

y = 13 ft

Step-by-step explanation:

The triangle is a 30-60-90 right triangle.

The ratio of the lengths of the sides is

short leg : long leg : hypotenuse = 1 : sqrt(3) : 2

From the ratio above we see that the hypotenuse is twice the short leg.

The long leg is sqrt(3) times the short leg.

y = short leg

x = long leg

26 ft = hypotenuse

y = 26 ft/2 = 13 ft

x = 13 ft * sqrt(3) = 13sqrt(3) ft = 22.5 ft
