Answer:
11
Step-by-step explanation:
X'Y' = 2XY . . . . lengths are related by the dilation factor
22 = 2XY . . . substitute the given value
11 = XY . . . . . divide by 2
The measure of side XY is 11.
Answer:
b) y=60x + 100
Step-by-step explanation:
Answer: x = 7, y = -3
<u>Step-by-step explanation:</u>
3y = 26 - 5x --> added 5x to both sides to get: 5x + 3y = 26
Elimination method (I am going to eliminate "x":
5x + 3y = 26 → 6(5x + 3y = 26) → 30x + 18y = 156
6x + 7y = 21 → -5(6x + 7y = 21) → <u> -30x - 35y</u> =<u> -105</u>
-17y = 51
<u> ÷-17 </u> <u>÷-17</u>
y = -3
Now, input y = -3 into one of the original equations to solve for "x":
3y = 26 - 5x
3(-3) = 26 - 5x
-9 = 26 - 5x
-9 -26 = -5x
-35 = -5x
7 = x
Answer:
y= 18
x= 15
Step-by-step explanation:
24 ÷ 16 = 1.5
12 x 1.5 = 18
10 x 1.5 = 15
Answer:
There is one theorem in triangle which states that sum of any two sides of a triangle is greater than the third side. For example, if a,b and c are three sides of a triangle, then a+b>c, b+c>a and a+c>b.
So, we will use here same concept.
Let a=5cm, b=7cm and c=12cm
a+b = 5+7 = 12cm which is equal to c.
<em>But a+b should be greater than c.</em>
Therefore, the triangle doesn't exist.
