Answer:
x = -2 , y = 4
Step-by-step explanation:
given:
5x + 2y = -2 <em>*4</em>
4x + 3y = 4 <em>*5</em>
Solving simultaneously,
20x + 8y = -8 ....eq 1
(-) 20x +15y = 20 ...eq 2
.............................................
-7y = -28
y = -28 / -7
y = 4
using equation 2,
20x +15(4) = 20
20x = -40
x = -2

Answer:
90°
Step-by-step explanation:
Angle C = arccos((84²+13²-85²)/(2×84×13))
= arccos(0/2184)
= arccos(0)
= 90°

Step-by-step explanation:
Use the Rational Zero Theorem to list all possible rational zeros of the function.
Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial. ...
Repeat step two using the quotient found with synthetic division. ...
Find the zeros of the quadratic function.
The answer is C. 50 in, 48 in, 14 in
In a right triangle, a² + b² = c², where c is the longest side (hypotenuse), a and b are the other two sides.
14² + 48² = 196 + 2304 = 2500
50² = 2500
