Answer: the correct answer is ( 7 * 5 ) + (7 * 9 )
Step-by-step explanation:
7 * ( 5+9) = (7 * __) + ( 7 * __) = ( 7 * 5 ) + (7 * 9 )
Answer:
the vertex represents a maximum
Vertex is (4,7)
f(x)=-(x-4)^2+7
Step-by-step explanation:
Given the function
Equation is in the form of y=ax^2+bx+c
When 'a' is negative, then vertex is maximum
when 'a' is positive, then vertex is minimum
is negative, so the vertex represents a maximum
, factor out negative
Take out negative sign in common
The angle measurements of angle B as represented in the diagram shown is 150°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
∠A = ∠B (alternate interior angles)
Hence:
8x - 10 = 3x + 90
x = 20
∠B = 3(20) + 90 = 150°
The angle measurements of angle B as represented in the diagram shown is 150°

the eqaution of a line is:
y = mx + b
where,
y = y - coordinates
m = slope
x = x - coordinates
b = intercepts
so with the values given as:
m = 4
b = 12
so the equation of line with the given values is
y = 4x + 12
The formula for b from the given area is equal to (2A / h).
As given in the question,
Formula to find area of a triangle is equal to A = (1/2) b h
b represents the base of the triangle
h represents the height of the triangle
A = (1/2) b h
Multiply both the side by 2 in area formula
2A = b h
Divide both the side by h
b = (2A) / h
Therefore, the formula for b from the given area is equal to (2A / h).
The complete question is:
The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.
