Answer:
Step-by-step explanation:
It is vital to first find the gradient/ slope between the points

let us use the point (6,1) to find the value of c
y=mx+c
1=1(6)+c
1-6=c
∴c=-5
the equation is given by
y=x-5
Answer:
The possible graph is "A". A further explanation is given below.
Step-by-step explanation:
The given values are:
Dominick spends on running
= 0.70 hours
He spends on swimming
= 1.5 hours
This week,
Dominick spends more than six hours.
If,
Number of runs be "x".
Number of swimming be "y".
then,
⇒ 
⇒ 
⇒ 
Therefore, 
x = 0
y = 4
So the above is the correct answer.
Answer:
16
Step-by-step explanation:
Given:
f(x)=3x+7 eq1
to find
f(3)
subtitute 3 in eq 1
<em>therefore,</em>
3*3+7=16
Answer:
about x=38.1
Step-by-step explanation:
9x38.1=342.9
Answer:
x is 4
Step-by-step explanation:
4x+23 is equal to 10x-1 because it is an isoceless triangle
4x+23=10x-1
subtract 4x add 1
24=6x
divided by 6
4=x
