So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
Answer:
there is no slope the answer is undefined
Step-by-step explanation:
the line in this case is a vertical line which would be an undefined line a horizontal line has a slope of zero.
the equation for slope is y^2-y^1/x^2-x^1
Answer:
One
Step-by-step explanation:
(x + 12) = 4x - 1
x + 12 = 4x - 1
12 = 3x - 1
13 = 3x
x = 13/3 = 4.3333333...
Since x only has one value, only one solution exists for the equation.
Answer:
2
Step-by-step explanation:
i don't know step by step but I have this same problem and the answer is 2
Step-by-step explanation:
<h3>Let the literate and illiterate people of Rashkundu Village be 4x and x respectively then </h3><h3>4x + x = 6550</h3><h3>5x = 6550</h3><h3>x = 6550 / 5</h3><h3>x = 1310</h3><h3 /><h3>Therefore </h3><h3>no. of literate people = 4 * 1310 = 5240</h3><h3 /><h3>no. of illiterate people = 1310 </h3><h3 /><h3>Hope it will help :)</h3>
