Answer:
x38
Step-by-step explanation:
The generic equation for a linear function can be expressed in the slope intercept form f(x) = mx + b, where m is the slope and b is the y intercept. For this problem we can first find the equation of the line. Then we substitute x = 7 to get the f(x) value, which is n at the point x = 7.
To find the equation of the linear function we first find the slope. Slope is defined as the change in f(x) divided by the change in x. As we are given a linear function, the slope at every point is the same. We can pick any two points known to find the slope.
Let's pick (3, 7) and (9, 16). The slope m is m = (16-7)/(9-3) = 9/6 = 3/2.
Now that we have the slope, we can plug in the slope and one of the points to find b. Let's use the point (3, 7).
f(x) = mx + b
7 = (1/2)(3) + b
b = 11/2
Now we can write the equation
f(x) = (1/2)x + 11/2
Plugging in x = 7 we find that f(7) = 9. n = 9
Area of a rectangle: 2(L+W)
length: 4+W
Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm
Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm
• The length is 26cm and width is 22 cm.
Answer:
<u>210</u>
Step-by-step explanation:
Use the order of operations pemdas( <u>p</u>arenthesis, <u>e</u>xponent, <u>m</u>ultiply, <u>d</u>ivide, <u>a</u>dd, <u>s</u>ubtract)
first do everything within the parenthesis.
3 ( ( 3 (9-2) ) + ( 7 (8-1) ) )
3 ( ( 3 (7) + ( 7 ( 7 ) ) )
3 ( ( (21) + (49) ) ) )
3 ( ( 21 + 49 ) )
3 ( 70 )
3 (70) = 70 + 70 + 70 = 140 + 70 = 210
