Well 117/9=13 so kari has $13
<span>( 5, 2) and ( 6, 4)
slope m = (4-2)/(6-5) = 2
y = mx + b
b = y - mx
b = 2 - 2(5)
b = 2 - 10
b = -8
so now you have slope m = 2 and y intercept b = -8
equation
y = 2x - 8
answer
</span><span>a. y = 2x - 8</span>
Answer:
A
Step-by-step explanation:
Both points are positive in the 1st quadrant.
Answer:
width = 150 yards
length = 200 yards
Step-by-step explanation:
Using the information given to us, we can make the following two equations:
2L + 2W = 700
L = W + 50
where L is the length in yards and W is the width in yards. This could treat these two equations as a system of linear equations. There are multiple ways to solve a system of linear equations, but I am going to solve this by substitution. Before doing that, I am first going to simplify the first equation, as it will make solving the system easier.
2L + 2W = 700
Divide both sides by 2.
L + W = 350
Since L = W + 50, we can substitute W + 50 for L in the equation L + W = 700.
(W + 50) + W = 350
2W + 50 = 350
2W = 300
W = 150
Now that we found what W is, we can solve for L by plugging 150 into either one of the equations. I am going to plug it into the equation L = W + 50.
L = 150 + 50
L = 200
Now we found what L is. So now we know that the width is 150 yards and the length is 200 yards.
I hope you find my answer and explanation helpful. Happy studying. :)
Answer: x = 28
method: You have to get the three missing sides of each shape, one of which you can get straight away because there's a rectangle in the middle and in a rectangle, opposite lines are equal, therefore, the missing length is 10. The other two lengths are the same because the dimensions of each triangle is the same, so you can just find one and multiply it by 2. To find one, you need to use Pythagoras' Theorem (c^2 - b^2 = a^2), so 15^2 - 12^2 = 81, and the square root of 81 is 9. 9 × 2 = 18, so added to the 10 you get your final answer as 28. I hope this helps! Let me know if you need me to explain it more :)
