Answer:
24 cm squared
Step-by-step explanation:
cut the dotted line and move the new triangle to the other side this makes a square 4*6=24 cm squared.
Answer:
The = sign
Step-by-step explanation:
1 11/20 = 31/20 = 1.55 and 1.55 =1.55
Answer:
A. 
B. b > 11
C. 
D. 
Step-by-step explanation:
<u>Given the following algebraic expression;</u>
A. 
We would simplify the equation by multiplying all through by 4;
Divide both sides by -3;
B. 5b - 28 > 27
Rearranging the equation, we have;
5b > 27 + 28
5b > 55
Divide both sides by 5
b > 11
C. 
Divide both sides by 13
D. 
Collecting like terms, we have;
Divide both sides by -1
Answer:
x = -2
x = -9
Step-by-step explanation:
The linear system is:
8x - 4y = 20 ⇒ (1)
5x - 8y = 62 ⇒ (2)
To solve the system multiply equation (1) by -2 to make the coefficients of y equal in values and different in signs, then add the resulting equation with equation (2)
∵ -2(8x) + -2(-4y) = -2(20)
∴ -16x + 8y = -40 ⇒ (3)
- Add equation (2) and (3)
∴ -11x = 22
- Divide both sides by -11
∴ x = -2
Substitute the value of x in equation (1) or (2)
∵ 8(-2) - 4y = 20
∴ -16 - 4y = 20
- Add 16 to both sides
∴ - 4y = 36
- Divide both sides by -4
∴ y = -9
Hey!!
How do you find slopes?
Ans - In order to find slop, we will need to use the slop formula which is
( y₂ - y₁ ) / ( x₂ - x₁ )
Now let's take two points on the graph
I will take the points ( -1 , 0 ) and ( 1 , 2 )
Now let's plug in these values :
y₂ = 2 , y₁ = 0 and x₂ = 1 and x₂ = -1
( 2 - 0 ) / ( 1 + 1 )
2 / 1
Hence, the slope is 2
Hope my answer helps!!
