Answer:
No solutions
Step-by-step explanation:
So putting that into an equation it equals
2k+8=(4k+14)÷2
Move the 2 to the other side.
2∙2k+8=4k+14
Simplify.
4k+8=4k+14
It doesn't make sense so No Solutions
Given:
The two expressions are


To find:
Whether the given expression are equivalent or non-equivalent.
Solution:
If two expressions are looking different but they are equal after simplification, then they are called equivalent expressions.
The first expression is

The first expression is equal to the second expression after the simplification.
Therefore, the given expressions are equivalent.
Yayyyy I’m so happy you got good grades
Answer:
A.6.2i-4.2 j
Step-by-step explanation:
We are given that



We have to find the projection of w on to u.
The project of vector a on b
=


Using the formula
The projection of w on to u

The projection of w on to u=6.2i-4.2j
Hence, option A is true.
The value of y is 56 when x = 8.
Given
y = 343 when x = 49
Value of y varies directly with x
Therefore, y ∝ x
We can write the equation with a constant 'k'
y = kx
When y = 343 and x = 49
343 = k × 49
k = 343/49
k = 7
When x = 8,
y = kx
y = 7 × 8
y = 56
The value of y is 56 when x = 8.
