Answer:
The equation of the straight line y = -2x +3
y-intercept = 3 and m =-2
Step-by-step explanation:
Step(i):-
Given that the points are ( 2,-1) and (-3,9)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{9-(-1)}{-3-(2)} = \frac{10}{-5} = -2[/tex]
Step(ii):-
The equation of the straight line passing through the point ( 2,-1) and slope m=-2
y-y₁ = m( x- x₁)
y -(-1) = -2 ( x-2)
y +1 = -2x +4
2x +y +1-4 =0
2x +y -3 =0
Final answer:-
The equation of the straight line y = -2x +3
solve the following system by substitution y=5x-4 y=6x
Answer:
Step-by-step explanation:
y = 5x - 4
y = 6x $\Rightarrow$ x = y/6
y = 5*y/6 - 4
y = 5y/6 - 4
6y = 5y - 24
y = -24.
So, x = -4
solve this algebra 1/4-2
Answer:
Step-by-step explanation:
Change 2 to 2/1, then multiply the top and bottom by 4 so it has the same denomiator as the 1/4.
[tex]\frac{1}{4} -\frac{8}{4} =-\frac{7}{4}[/tex]
Answer:
-1 3/4
Step-by-step explanation:
Make the denominator the same
2 = 8/4
1/4 - 8/4 = -7/4 (mixed number: -1 3/4)

Sara and Fiona have played 53 tennis matches.
Sara has won 29 times.
Fiona won the rest.
a) Estimate the probability that Sara wins.
b) Estimate the probability that Fiona wins.
Answer: Sara = 29/53
Fiona = 24/53
Step-by-step explanation: because that amount is how much they have won and how much its out of so for example ‘i played 26 games i only won 17 and John won the rest’ the probability that i win is
17/26 and Johns would be 9/26

Find f(2) if f(x) = (x + 1)2.
a 9
b 6
c 5
Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.

Step-by-step explanation:
Is 3 a factor of 245 - 16?
yes
no
HELPPP
Answer:
No
Step-by-step explanation:
For 3 to be factor your finale number has to be divisible by 3, so with that information all you have to do is subtract 245-16 which is 229, and if you divide 229 by 3 it does not equal a whole number so 3 cannot be a factor.
I hope this helps, and have a great day! :D
