Answer:
If they are asking about the y intercept then rearrange this as y=mx+c
so y=-4x+10
here 4 is the gradient and 10 is the y intercept
Step-by-step explanation:
Answer:
1933
Step-by-step explanation:
9 x (1 + 345) - 6 - 8 + 48 x 23 - 77
Use BODMAS method to solve these type of equation
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
_________________________________________________________
Brackets - 1 + 345 = 346
Multiplication
9 x 346 = 3114
48 x 23 = 1104
Lets rewrite the equation now
3114 - 6 + 1104 - 77
Addition
6 + 1104 = 1110
Subtraction
3114 - 1104 = 2010
2010 - 77 = 1933
Answer = 1933

Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.
On cross multiplication, we get
![[\because 1\ m=100\ cm]](https://tex.z-dn.net/?f=%5B%5Cbecause%201%5C%20m%3D100%5C%20cm%5D)
Therefore, the actual dimension is 3.84 m.
Hello!
Add up the costs of everything Kyle purchased and the tax, and then subtract that from $10.
4.95 + 2.30 + 1.10 + 0.65 = 9
10 - 9 = 1
Kyle should have received $1 change.
Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
