Answer:
x=sqrt{22}
Step-by-step explanation:
Answer:
R = (- 3.5, - 7 )
Step-by-step explanation:
Using the Section formula
= 
= 
= 
= - 3.5
= 
= 
= 
= - 7
Thus coordinates of R = (- 3.5, - 7 )
Answer:
y = -24 + -2x + 2x2
Step-by-step explanation:
Simplifying:
y = 2(x + 3)(x + -4)
reorder the terms:
y = 2(3 + x)(x + -4)
multiply (3 + x) * (-4 + x)
y = 2(3(-4 + x) + x(-4 + x))
y = 2((-4 * 3 + x * 3) + x(-4 + x))
y = 2((-12 + 3x) + x(-4 + x))
y = 2(-12 + 3x + (-4 * x + x * x))
y = 2(-12 + 3x + (-4x + x2))
Combine like terms 3x + -4x = -1x
y = 2(-12 + -1x + x2)
y = (-12 * 2 + -1x * 2 + x2 * 2)
y = (-24 + -2x + 2x2)
Solving:
y = -24 + -2x + 2x2
solving for variable 'y'
Move all terms containing y to the left, all other terms to the right.
Simplifying:
y = -24 + -2x + 2x2
Answer:
16
Step-by-step explanation:
5 × 320 ÷ 100 = 16
5 × 320 = 1,600
1,600 ÷ 100 = 16
16 es tu repuesta
Answer:
6.) -3.544
Step-by-step explanation:
6.2(x+3.5)-x =6.2x+21.7 -x =6.2x-x+21.7 =5.2x+21.7
-3(6-2x) =-18(+-)6x =-18-6x
5.2x +6x=-18-21.7
11.2x=-39.7
x=-39.7÷11.2
x=3.544
