Answer:
D. R(x)=850x+9600
Step-by-step explanation:
Use the given information as points on a line, and find the slope.
The two given points are (10, 18,100) and (20, 26,600).
slope = (difference in y)/(difference in x)
slope = (26,600 - 18,100)/(20 - 10)
slope = 8,500/10
slope = 850
Only choice D. has a slope of 850.
Answer: D. R(x)=850x+9600
Answer:
y+8 = 2(x-4)
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.
And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:
y-y1 = m(x-x1)
Answer:
0.533
Step-by-step explanation:
Answer:
x=5
From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.
In geometry, if a triangle has two congruent sides, then we can call it a <em>isosceles triangle</em>.
In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.
We also know that angles in a triangle add up to 180 degrees.
So, we have: 88+(9x+1)+(9x+1) = 180
Simplifying: 18x + 2 = 92
Solving: 18x = 90, so x=5
Hope this helps!
