Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) = x + ( x + 9 )
Now, solving the given expression
Or, × 4 + × 6 x = x + x + × 9
Or, + × x = x + x +
or, 2 + 3 × x = + + 6
or, 2 + 3 × x = + 6
or, 2 + 3 × x = + 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x =
I.e x = 2
Hence The value of x for the expression is 2 Answer
Answer:
Linear function
Explanation:
Given the scattered plot in the attached image.
We want to identify the type of function that can best model the given scattered plot.
The scattered point as shown in the attached image form a straight line, So, the best type of function that can best model it is a linear function (straight-line graph).
3 * (1/2^-4) + 100 =
3 * (16) + 100 =
48 + 100 = 148
Step-by-step explanation:
gradient = (y2 - y1)/(x2 - x1)
-1/2 = (r - 2)/(3 - (-3))
-1/2 = (r - 2)/6
-1/2(6) = r - 2
-3 = r - 2
-3 + 2 = r
hence r = -1.
Answer:
8 minutes
Step-by-step explanation:
Let t represent the time for one mile. We are told the ratio of minutes to miles is constant, so we have the proportion ...
time / distance = t/(1 mi) = (208 min)/(26 mi)
Multiplying both sides of the equation by (1 mi), we have ...
t = (208/26) min = 8 min
Geri's average pace was 8 minutes to run 1 mile.
