y = - (x - 5)² + 4
the equation of a quadratic in standard form is
y = a(x - h)² + k ( where (h , k ) are the coordinates of the vertex and a is a multiplier )
given vertex = ( 5, 4 ) then
y = a(x - 5)² + 4 ( to find a substitute (7 , 1 ) into the equation )
1= 4a + 4
4a = - 3 ⇒ a = -
y = - (x - 5)² + 4 ← ( in vertex form )
Answer:
7m-3x-1
10x+26
7x-12
Step-by-step explanation:
3m - 1 + 4m -3x
sum terms by the same variable:
3m+4m=7m
we have:
7m-3x-1
7(3+2x)-4x+5
apply the distributive property:
7*3+7*2x-4x+5
we have:
10x+26
3x+4(x-3)
apply the distributive property:
3x+4*x-12
we have:
7x-12
Answer:
5(4) + 5(8)
Step-by-step explanation:
Through destributive property, 5 is multiplied by both 4 and 8
Answer:
135°
Step-by-step explanation:
To convert from radian measure to degree measure
degree measure = radian measure × , so
degree = ×
Cancel π on numerator/denominator and 4, 180 by 4, leaving
degree = 3 × 45 = 135°
