Answer:
See below
Step-by-step explanation:
11 box 1: 12
11 box 2: 101
12 box 1: 80
12 box 2: 80
12 box 3: 80
13 box 1: 16
13 box 2: 16
13 box 3: 76
20 = y + 12
20 - 12 = y + 12 - 12
8 = y
x + 2 = 19
x + 2 - 2 = 19 - 2
x = 17
z - 313 = 176
z - 313 + 313 = 176 + 313
z = 489
Answer:
Length of Bar JK=l
Bar (JK) is dilated by a scale factor of n, having origin as the center of dilation.
New line segment formed named bar (J'K').
As given slope of bar(JK) =m
When we dilate a line segment with respect to origin , having origin as the center of dilation, there is no effect of slope on Dilation.
Length of bar (J'K')= (Length of bar JK)×(Scale factor)
= l×n Or n×l
Option (D) is correct.
Answer:
The original nimber is 67.
Step-by-step explanation:
Let the two digits be x and y.
According to the question.
The sum of two digits of a two digit number is
x + y = 13
or, x = 13 - y
And, a two digit number can be written as
x × 10 + y
when the digits are reversed, the number can be written as
y × 10 + x
the original number increases by 9. i.e.
y x 10 + x = x × 10 + y + 9
Replacing value of x by 13 - y,
y × 10 + 13 - y = 10(13 - y) + y + 9
10y + 13 - y = 130 - 10y + y + 9
9y + 13 = 139 - 9y
18y = 139 - 13
18y = 126
y = 126/18
y = 7
So, x = 13 - y
= 13 - 7
= 6
The original number is x × 10 + y = 6 x 10 + 7 = 67.
Answer:
180-30=150
180-165=15
Step-by-step explanation:
Y = 2x + 3
In function notation, all u do is change the y to f(x)
f(x) = 2x + 3 <== function notation.
