Answer:
1. 15
2. 45
3. There is a missing digit.
Step-by-step explanation:
Given: <u>y=3</u> and <u>x= 1/2</u>
<h2>Question 1: 4(2y-4x)-1=</h2>- Numerical factors in this term have been multiplied.
4(6-4/2)-1
- We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.
4(6-2)-1
- Numerical terms in this expression have been added.
4*4-1
- Numerical factors in this term have been multiplied.
16-1
- Numerical terms in this expression have been added.
15
<h2>Question 2: 4x^2+2y^3-10 = </h2>4/2²2*27-10
4/2²+54-10
- We need to perform a multiplication.
- The following rule is applied:

Answer:
66%(technically 0.66 repeating)
Step-by-step explanation:
We need to figure out what percentage of 69 equates to 46. In other words, we need to figure out what percentage <u>times</u> 69 equals 46:
Now that we formed this equation, we can solve for the percentage as if it was x.
First lets simplfy:
Now we can solve for x just by getting x alone, which means we must remove the coefficent. We can do this by dividing both sides of the equation by 69:
=
Putting this into the form of percentage, we must multiply by 100. Since, the percentage form of a decimal is 100 times bigger(moved up 2 decimal places):
=
percentage = 66%

Answer:
The value of y is 5 , and The value of x is - 5
Step-by-step explanation:
Given as :
The line passes through point ( - 2, 5)
The slope of line is m =
Equation of line is written as
y - = m × (x -
)
Since line passes through line ( - 2 , 5 ) and have slope
So, y - 5 = × (x + 2)
Or, 3 × ( y - 5 ) = 2 × ( x + 2 )
Or, 3 y - 15 = 2 x + 4
Or, 3 y - 2 x - 19 = 0 is the equation of line
Now points ( x , 3 ) lies on the line 3 y - 2 x - 19 = 0
So, 3 × 3 - 2 x - 19 = 0
or, 9 - 2 x - 19 = 0
or, 2 x = - 10
∴ x = -
I.e x = - 5
Again points ( - 2 , y ) lies on the line 3 y - 2 x - 19 = 0
So, 3 × y + 2 × 2 - 19 = 0
Or, 3 × y + 4 -19 = 0
or, 3 y = 15
∴ y =
I.e y = 5
Hence The value of y is 5 , and The value of x is - 5 . Answer
