Answer:
4b -5
Step-by-step explanation:
Perform the indicated multiplication first: 4b - 24 + 19. Next, combine like terms, obtaining 4b -5 (answer)
Answer:
Is not a right triangle
Step-by-step explanation:
we know that
The length sides of a right triangle must satisfy the Pythagorean Theorem

where
c is the greater side (the hypotenuse)
a and b are the legs
<u><em>Verify</em></u>
we have

substitute



so
The length sides of triangle not satisfy the Pythagorean Theorem
therefore
Is not a right triangle
Answer:
Step-by-step explanation:
Question 1:
3.6 ÷ y =1.2 ÷ 2
(3.6) (2) = (1.2) (y)
7.2 = 1.2y
y = 6
Question 2:
5 ÷ 25 = m ÷ 125
(5) (125) = (25) (m)
625 = 25m
m = 25
Question 3:
1/2 = 0.5
n ÷ 0.5 = 6 ÷ 1
n = 6 × 0.5
n = 3

<h3>What is exponents?</h3>
A symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power.
The given table values satisfied the fourth function.
If we put one by one all the values of x given in a table we get the corresponding value of f(x).
like, if we put -2 we get f(x)= 75 closer to 71
Hence, Exponential model best represents the data is

Answer:
The slope is 2/3 and the function is y=2/3x which is a direct variation function.
Step-by-step explanation:
To find the slope of a line between two points, we use the equation
m = (y2-y1)/ (x2-x1)
where (x1,y1) and (x2,y2) are the two points
m= (4-2)/(6-3)
= 2/3
The slope of the line is 2/3
The equation of the line is
y-y1 = m(x-x1)
y-2 = 2/3(x-3)
Distribute
y-2 = 2/3x -2
Add 2 to each side
y-2+2 = 2/3x -2+2
y = 2/3x
This is a direct variation function
Let x = -6
y = 2/3(-6)
y = -4
(-6,-4)
