Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.
Answer:
0.1
Step-by-step explanation:
(9,4) (5,1)
, plug in the numbers,
=
, to write it as a decimal, you divide the numerator by the denominator, 0.1
When using substitution, we are imputing an equation in place of a variable to eliminate one of the variables in the equation so that we can solve for the remaining variable.
For this example, we will be plugging in (-4y+12) wherever "x" is in the other equation.
3/4 x -5y = 7
3/4(-4y+12) -5y =7
((3/4)(-4y))+((3/4)12)-5y=7
-3y+9-5y=7
-8y= -2
y=(1/4)
Now find "x" by plugging in the y-value.
x=(-4*(1/4))+12
x= -1 +12
x=11

Answer: 27
Explanation: Bunny&Cat=10kg it can be 1/9,2/8 etc. it’s 3/7 Bunny 3 Cat 7. With that we know the Dog weighs 17 kg. 17 Dog + 7 Cat= 24. With that it’s easy, 3+7=10+17=27
we are given
distance=6.7 furlongs
(a) In rods
we know that

we can multiply both sides by 6.7
