Lacey can type 105 words in 3 minutes. At this rate, how many words can she type in 26 minutes
2 answers:
This is a proportion problem. set the two over fractions and equal them to each other. you should have x, or any variable, in place for the number of words she will type in 26 minutes, since this is what we are solving for. cross multiply and divide and you get the answer for x, which is 910.
x= 910

Answer:
y = x - 5
Step-by-step explanation:
The equation of the line parallel to the line is
.
That is, equations of parallel lines differ only by constant.
The given equation is
This is written as
Therefore, the equation of the line parallel to this line is given by
The value of c is determined using the point given.
Substituting the point (3,-2) we get:
Therefore, the equation of the line becomes y = x - 5.
The function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
The graph of a function f(x) passes through the following points: (0,2), (1, 0), (-1,0)
Let
f(x) = ax² + bx + c
Plug x = 0, and y = 2
c = 2 ...(1)
Plug x = 1 and y = 0
a + b + c = 0 ..(2)
Plug x = -1 and y = 0
a - b + c = 0 ...(3)
After solving (1), (2), and (3)
a = -2
b = 0
c = 2
f(x) = -2x² + 2
Thus, the function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)
