Well you subtract d from both sides with would make 2D-4=-8. Then you subtract four to both sides which is -12. Then you divide -12 by 2D which is 6. D=-6
He drove 56 miles because if you divide 168 and 3 it equals 56.
Answer:
Given the ordered pairs, the exponential growth function would be represented by f(x)=35(1.6)^x.
Step-by-step explanation:
Exponential growth functions are represented by the following equation: f(x)=ab^x, where 'a'=initial value; 'b'=rate of growth; 'x'=independent value or time. Given the points, we see that the values of 'x' increase by 1 each time and dividing two 'y' values (35/21.875; 56/35; 89.6/56) gives us a change of 1.6. Rate is the change in y/the change in x, or 1.5/1, which is the value of 'b'. When 'x' is equal to 0, the value of 'y' is 35, so this represents the initial value, or 'a'. Plugging in these values will give us the final equation f(x)=35(1.6)^x.
The equation that matches the given points is g(x) = -1.4x + 7.6
The standard form of a linear equation is expressed as 
- m is the slope of the line
Using the coordinate points (3, 3.4), (4,2)
Substitute m = -1.4 and the coordinate (4, 2) into the formula:
Get the required equation:
Hence the equation that matches the given points is g(x) = -1.4x + 7.6
