Answer:
3
Step-by-step explanation:
The value of x = 3/5
y = 1/3
z = 2 4/5
The value of z is in whole number fraction so, let us convert it to improper fraction.
z = 2 4/5 = 14/5
Now let us work out the value of z + x times y. This can be translated mathematically as follows
z + x × y
let us insert the values
14/5 + 3/5 × 1/3
using the PEMDAS principle, multiplication comes before addition therefore, we will do the multiplication before addition.
3/5 × 1/3 = 1/5
14/5 + 1/5 = (14 + 1)/5 = 15/5 = 3
the answer is d a decrease by 5/11
Answer:
Step-by-step explanation:
f(x)=x+5 and g(x)=2x
(f∘g)(x)=f(g(x))=f(2x)=5+(2x)=2x+5
(g∘f)(x)=g(f(x))=g(x+5)=2(x+5)=2x+10
(f∘g)(x)=2x+5
(g∘f)(x)=2x+10
Answer:
148 in^2
Step-by-step explanation:
2(4 x 5) = 40
2(4 x 6) = 48
2(5 x 6) = 60
Answer:
b = 0
Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 2x + 17 is in this form with slope m = - 2
• Parallel lines have equal slopes, hence
slope of line through the 2 points is - 2
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (b, 7)
m = = , hence
= - 2 ( cross- multiply )
- 2(b - 2) = 4
- 2b + 4 = 4 ( subtract 4 from both sides )
- 2b = 0 ⇒ b = 0
