We know that
in the equation <span>ŷ = 10 + 20x
the value of 10 is the p</span><span>redicted value of Y,
given X=0 value.
</span>It is also known as Y intersect
Translate into math language:
7 - 3x = 23→ -3x = 23-7 → - 3x = 16 and x = - 16/3
The algebraic expression is x = 2y where, "x" is the number of goals with Kumar and "y" is the number of goals with Jacob
<em><u>Solution:</u></em>
Given that Kumar has twice the number of goals as Jacob
To find: algebraic expression
An algebraic expression is a mathematical expression that consists of variables, numbers and operations
<em><u>Let us first define the variables</u></em>
Let "x" be the number of goals with Kumar
Let "y" be the number of goals with Jacob
Then from given statement,
Number of goals with kumar = twice the number of goals as Jacob
Number of goals with kumar = 2(number of goals with Jacob)
x = 2y
Thus the algebraic expression is found
Answer:
option c in both cases
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁ )
where m is the slope and (x₁, y₁ ) a point on the line
(1)
Here m = 2 and (x₁, y₁ ) = (- 3, - 5) , then
y - (- 5) = 2(x - (- 3) ) , that is
y + 5 = 2(x + 3)
(2)
Here m = 4 and (x₁, y₁ ) = (- 6, - 3) , then
y - (- 3) = 4(x - (- 6) ) , that is
y + 3 = 4(x + 6)
