Answer:
Option 2
Step-by-step explanation:
Given
B = (-6,1)
B' = (-3,-2)
Step 1: Substitute the original and translated coordinates into (x,y) => (x+a,y+b)
B(-6,1) => B'(-6+a , 1+b) = B'(-3,-2)
Step 2: Write two equations
-6+a = -3 => a = -3+6 = 3
1+b=-2 => b = -2-1 = -3
Hence, we can conclude that Indira wrote the equations wrong which was her first error.
Therefore, Option 2 is correct ..
Answer:
x=27 and NL = 40
Step-by-step explanation:
by properties of secants starting from common point-
LK x LJ = LM x LN
10 * (10+42) = 13 * (13+X)
X = 27
Answer:
the last choice shown here: F'(0, -4), G'(-3, -1), H'(-2, 2), I'(0, -2)
Step-by-step explanation:
The translation vector tells you that the new coordinates are found by adding -4 to each of the old coordinates. When you realize that the answer choices differ in their values for H' and I', you can conclude that you only need to find one of those to determine the correct answer.
H' = H + (-4, -4) = (2-4, 6-4) = (-2, 2) . . . corresponds to the last choice shown
_____
When you subtract 4 from each of the coordinates of the other points, you find they also match the last answer selection.
Answer: y = 1x + -4
Equation of a straight line:
y = mx + b ------(i)
Step by Step Solution:
Step 1: Calculating Slope (m).
m = y2-y1 /x2-x1
m = 3--1 /7-3
m = 4/4
m = 1
Now putting value of m in equation (i)
y = 1x + b -----(ii)
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (3,-1) for calculating y-intercept:
y = mx + b
-1 = 1(3) + b
-1 = 3 + b
-4 = b
b = -4
Now putting value of b in equation (ii)
y = 1x + -4
Step-by-step explanation:
Given that the base of triangle is 9/4 times of its height . And area is 144 cm² . Let the height be h , then its base be 9h/4 .
<u>•</u><u> </u><u>Acco</u><u>rding</u><u> </u><u>to</u><u> </u><u>Question</u><u> </u><u>:</u><u>-</u><u> </u>
Therefore ,
- Height = h = 8cm .
- Base ,= 9h/4 = 18cm .
