Answer:
3.) 63=3x+7y
4.) Y-intercept is 9
Step-by-step explanation:
(For 3) For every time a person gets a touchdown, x represents that
for every time a person person scored a successful extra-point attempt, y represents that.
And they team scores 63, so....
the equation would look like this
63=3x+7y
(For 4) You find the y-intercept by turning the standard form equatio into the slop intercept form
(Helper's note, multiplying by its reciprocal is the same as dividing it by a whole number, in the case dividing the number by 7 is the save as multiplying the number by
)
Then plugging x=0 and solve for y, which in this case, y=9

(For the graphing) Turn 63=3x+7y into a slope intercept form, which is
and graph from there
The mapping is not a function
Answer:
(x+5/2)^2 = 0
Step-by-step explanation:
4 x^{2} +20x +25 =0
Divide by 4
4/4 x^{2} +20/4x +25/4 =0
x^2 +5x +25/4 =0
Subtract 25/4 from each side
x^2 +5x +25/4 -25/4 =-25/4
x^2 +5x =-25/4
Take the coefficent of x
5
Divide by 2
5/2
Square it
25/4
Add it to each side
x^2 +5x +25/4 =-25/4+25/4
(x+5/2)^2 = 0
Take the square root of each side
x+5/2 = 0
x = -5/2
