Answer:-21
Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
3(3y − 12) = 0
Divide by 3
3/3(3y − 12) = 0/3
3y-12 = 0
Add 12 to each side
3y-12+12 = 0+12
3y = 12
3y/3 = 12/3
y = 4
The expected value of y when x-value is 45 is 35.06
Any equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not both zero, is called a linear equation in two variables. For example, y = 2x+3 and 2y = 4x + 9 are two-variable linear equations.
In the given question value of x is given and value of y is asked.
The given equation : y = -2.61x+152.51 Such questions can be solved by substituting the given value of variable in the equation which will help us find the unknown.
Substituting x = 45 in the given equation , we get
y = -2.61 x 45 + 152.51
y = -117.45 + 152.51
y = 35.06
Thus the expected value of y when x-value is 45 is 35.06

Example:
<span>To solve for the given, 7 hundreds x 10 in unit form and standard form </span>
<span>We can first standardize the given into a equation form which will be: </span>
<span>1. 700 x 10 which yield 7, 000 </span>
<span>700 x 10 = 7, 000 </span>
<span>Notice the amount of zero the value of 700 attained. </span>
<span>2. The standard form then is 7, 000 </span>
<span>3. The word form of the product is seven thousand.<span> </span></span>
