Answer:
C. 2.25
Step-by-step explanation:
The following information is missing: <em>J is at (-3, 4). K is at (4,-2).
</em>
The x value for point L such that JL and KL form a 3:1 ratio is obtained as follows:
where ratio m:n givesfraction m/(m+n), run is the distance over x-axis between J and K, and xJ is the x-coordinate of J.
- ratio 3:1 means: m/(m+n) = 3/(3+1) = 3/4
Replacing into the equation:
m/(m+n)*run + xJ = 3/4*7 + (-3) = 2.25
Answer:
(B) -8
Step-by-step explanation:
Given the 2-column table below:
Taking the pair (-3,14) and (-1,10)
Taking the pair (1,6) and (4,0)
Slope, 
Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:
Taking the pair (8,y) and (4,0)
Slope, 
Therefore, the value of ? on the y-column is -8.
Answer:
Slope = -1/2
Y-Intercept = 2
Equation: Y=-1/2x+2
Step-by-step explanation:
Graph goes 2 units up at y=2, that's your y-intercept. From there, plot your second point by moving 1 down and 2 to the right from the y-intercept, landing on the point (2,1) to get your slope, written as -1/2.
Answer:
L = 3(4) + 2(3) + 6

.........
Answer:
129
Step-by-step explanation:
for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do
180=x+19+4x+1
step 1 combine like terms
4x+x=5x
19+1=20
now we have
180=20+5x
step 2 subtract each side by 20
20-20 cancels out
180-20=160
now we have
160=5x
step 3 divide each side by 5
5/5 cancels out
160/5 = 32
x=32
now we want to plug in 32 for each expression to find which one is greater
(32)+19=51
4(32)=128
128+1=129
so the answer is 129
hope this helps :D
