The answer to this would be 40 because you multiply 12x0.30 and get 40 which mean 12 is 30% of 40 total
Plug in 8 for g(8) to get 8(2) + 1 which is equal to 17, plug in 7 for f(x) to get 10-7 which is equal to 3. 17 + 3 is equal to 20 which means g(8) + f(7)= 20
Based on the fact that the sides of the rectangle are in the ratio 5:2, the length of each side is 20cm and 8cm.
<h3>What is the length of each side?</h3>
Based on the ratio, we can assume the a value of x for the perimeter to be:
Perimeter = 2 x ( length + width)
= 2 x (5x + 2x)
= 2 x 7x
= 14x
The value of x is:
56 = 14x
x = 56/14
= 4
The value of the sides are:
= 5 x 4
= 20 cm
= 2 x 4
= 8 cm

Answer:The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis
Step-by-step explanation:
Answer:
x = - 6 , x = 1
Step-by-step explanation:
to find the zeros let f(x) = 0 , that is
x² + 5x - 6 = 0
consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term ( + 5)
the factors are + 6 and - 1 , since
6 × - 1 = - 6 and 6 - 1 = + 5 , then
(x + 6)(x - 1) = 0 ← in factored form
equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 1 = 0 ⇒ x = 1
