Connor wants to solve the equation 4x=26. How could he use graphs to solve this equation?

astraxan [27]

Answer:

He should graph the functions f(x) = 4x and g(x) = 26 in the same coordinate plane. The x-coordinate of the intersection point of the two graphs is the solution of the equation.

Explanation:

To solve the equation 4x = 26 using graphs, he should graph two functions in the same coordinate plane. The intersection of the two graphs is the solution of the equation.

The functions to graph are f(x) = 4x, and g(x) = 26.

The graph of f(x) = 4x is a line that goes through the origin (0,0) and has slope 4.

Some of the points to graph that line are:

x f(x) = 4x

0 4(0) = 0 → (0,0)

2 4(2) = 8 → (2,8)

4 4(4) = 16 → (4,16)

6 4(6) = 24 → (4, 24)

With those points you can do an excellent graph of f(x) = 4x

The graph of g(x) = 26 is horizontal line (parallel to the y-axis) that passes through the point (0, 26), which is the y -intercept.

You have to extend both graphs until they intersect each other. The x-coordinate of the intersection point is the solution of the function.

The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the ai

vredina [299]

Answer:

909.8 millibars.

Step-by-step explanation:

The mean sustained velocity, v be determined by the equation:

$v=6.3\sqrt{1013-p}$ , where p is the air pressure, in millibars, at the center of the hurricane.

Given that: v=64 meters per second, we are to find the value of p.

$64=6.3\sqrt{1013-p}\\$Square both sides to eliminate the square root sign\\(64)^2=(6.3\sqrt{1013-p})^2\\4096=39.69(1013-p)\\$Divide both sides by 39.69$\\\dfrac{4096}{39.69}=1013-p\\ $Therefore:$\\p=1013-\dfrac{4096}{39.69}\\\\p=909.8$ millibars$

The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.

Walter has 124 bills consisting of 5 dollar bills and 10 dollar bills. If his total amount of money is $840, how many bills of e

Romashka [77]

For this question here are the formulas,
Let T be the number of 10's
Let F be the number 5's

Let us find the 10's first by this formula.
5(124 - T) + 10T = 840
620-5T + 10T = 840
then
5T = 220
5 5

T=44
Now let's find the F using this formula.

5F + 10T = 840
Sustitute T
5F + 10(44) = 840
5F = 400
5 5
F = 80

to Check
F + T = 124
80 + 44 = 124
