Answer: The polynomial
= y² - 5y - 4.
Step-by-step explanation:
Let the polynomial = f(y)
Therefore
y² -5y + 1 - f(y) = 5
f(y) = y² - 5y + 1 - 5
f(y) = y² - 5y - 4
The polynomial = y² - 5y - 4.
Check:
y² - 5y + 1 - ( y² - 5y - 4)
Open the bracket with the minus
y² - 5y + 1 - y² + 5y + 4
y² - y² - 5y + 5y + 1 + 4
= 0 - 0 + 5
= 5.
The will be answer is 132
First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39 /2
</span>⇒ 16x + 14y = 78
Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2
y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
Answer:
y + 3 = 1 ⋅ (x + 2).
Step-by-step explanation:
Find the equation using point-slope formula.
Slope-intercept form:
y = x − 1
Point-slope form:
y + 3 = 1 ⋅ (x + 2)
It is not an equation, it's a function & I guess you have to draw it
h(x) = - 2x/3 - 11/3
It's a linear function: To draw it, try to find 2 points, say A & B.
To find A, plug any (logical) number into x to find y. For instance , let x=0, if so y=-11/3 & the coordinate of the first point A(0, - 11/). Try to find B by following the same methodology
