5×1/4
5/4
1.25
Your answer is 1.25
Answer: (-3,9)
When we rotate 180 degrees about the origin, the rule is (x,y) --> (-x,-y). The coordinate signs have swapped. If x is negative, then x turns positive, or vice versa. The same applies for y as well.
x = 3 becomes -x = -3
y = -9 becomes -y = -(-9) = 9
Answer:
y=mx+b 58
Step-by-step explanation:
let area of triangle be x
let area of rectangle be y
Then,
2x = y
Step-by-step explanation:
Part A:
4x² - 7x - 15
a, b, c = 4, -7, -15
ac = -60
factors that add up to -7 and multiply to -60 are (-12, 5)
rewrite equation
(4x² - 12x) + (5x - 15)
factor out GCF from both groups
4x(x - 3) + 5(x - 3)
(4x+5)(x-3)
Part B:
Using the factored form from the previous part we can set both factors equal to 0 to solve for x.
4x+5 = 0
4x = -5
x = -5/4
x-3 = 0
x = 3
the two x-intercepts are -5/4 and 3
Part C:
Since the leading coefficient is positive, the right side of the function will be going up or to positive infinity as x goes towards positive infinity. Since the degree is even both sides go in the same direction so on the left side it also goes towards positive infinity as x goes towards negative infinity.
