Answer:
D. 30
Step-by-step explanation:
3 3/4 inches on the map is 15/4 inches = 15×(1/4 inch).
Then the actual distance is 15×(2 miles) = 30 miles.
X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3
Linear line formula: y = mx + b
m = slope
b = y-intercept
In this case the question gives us what we need to substitute.
m = 4
b = 3
y = 4x + 3

Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1
Answer:
22%
Step-by-step explanation:
Add all the numbers to get the total number of notebooks.
6 + 11 + 7 + 5 + 3 = 32
2. There are 7 purple notebooks. To find the percent chance that Maryam will buy a purple notebook, divide 7 by 32.
7/32 = 0.21875
3. Move the decimal to the right two places.
21.875
4. Round to the next whole number.
22%
