Answer:
17
Step-by-step explanation:
given
2f + 4f + 2 - 3 ← simplify by collecting like terms
= 6f - 1 ← substitute f = 3 into the expression
= (6 × 3) - 1 = 18 - 1 = 17
Answer:
Step-by-step explanation:
The standard way of writing equation of a line in a point-slope form is as given;
y - y0 = m(x-x0)
m is the slope of the line
(x0,y0) is a point on the line.
Given the point (-2,-6), in order to determine with of the equation that correctly uses the point, we will substitute the point into the formula and get the necessary equation.
y - y0 = m(x-x0)
y - (-6) = m(x-(-2))
y+6 = m(x+2)
Since we are not given the slope, let's assume the slope is 5/2
The equation becomes y+6 =5/2(x+2). Option D is correct
The model will be 5 times longer that stated.
E.g if the model is said to be 10 feet long using this scale.
10*5=50
50 feet
Answer:
3:1
Step-by-step explanation:
brown:black
15:5
Divide both sides by five;
15/5 :5/5
= 3:1
It is prime, it has no factors besides 1,23
