B 12:3 = 4-1=3 C 10- 7=3 And A 2+15x=x=15-2=13
Answer:
O= 90 because it is a right angle, 360 degrees (which is the whole circle) minus (50+90), equals 220.
Step-by-step explanation:
Line through (0,−3) slanting down.
1.4n represents the price and number of packages of pencils. 1.2m represents the number of paper pads and the price
Answer:
The correct option is:
h = 1, k = 16
Step-by-step explanation:
y=4x^2-8x+20 =0
It is a quadratic formula in standard form:
ax^2+bx+c
where a = 4 , b = -8 and c=20
The vertex form is:
a(x − h)2 + k = 0
h is the axis of symmetry and (h,k) is the vertex.
Calculate h according to the following formula:
h = -b/2a
h= -(-8)/2(4)
h = 8/8
h = 1
Substitute k for y and insert the value of h for x in the standard form:
ax^2+bx+c
k = 4(1)^2+(-8)(1)+20
k = 4-8+20
k=-4+20
k = 16
Thus the correct option is h=1, k=16....
