What is the distance between (4, 7) and (-8, 3)? Round to the nearest tenth.
Answers
Answer:
The distance is approximately 12.6.
Step-by-step explanation:
Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4. Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.
This distance, from the Pythagorean Theorem, is
d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.
The desired distance is approximately 12.6.

What is the x intercept of the graph of -4x = -20?
Answers
Answer:
x=5
Step-by-step explanation:
The x - intercept of the graph of the expression is (5, 0).
We have the following expression -
- 4x = - 20
We have to find the x - intercept of the graph of this expression.
What is the Slope - intercept form of the equation of a straight line ?The Slope - intercept form of the equation of a straight line is as follows-
y = mx + c
where -
m - slope of line
c - intercept of line on y - axis.
According to the question -
- 4x = - 20
x = 5
Hence, the x - intercept of the graph of the expression is (5, 0). Refer the graph attached in the end.

Answers
Answer:

Step-by-step explanation:
Solving an inequality is a lot like solving an equation, one uses inverse operations. The major difference between solving an inequality and an equation is that when one multiplies or divides by a negative number, then one must remember to flip the inequality sign, such a rule doesn't come into play in this case.

x^2-6x=b, make x the subject
Answers
Answer:
x = 3 ±√(b + 9).
Step-by-step explanation:
We use Completing the Square:
x^2 - 6x = b
(x - 3)^2 - 9 = b
(x - 3)^2 = b + 9 Taking square roots of both sides:
x - 3 = ±√(b + 9)
x = 3 ±√(b + 9).
Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)
Answers
Answer:
f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]
Step-by-step explanation:
Let the equation of the give cubic function is,
f(x) = p(x - a)(x - b)(x - c)
Here, a, b, c and d are the x-intercepts of the given graph.
Since, x-intercepts given in the graph are x = -5, 1 and 4,
Equation of the curve will be,
f(x) = p(x + 5)(x - 1)(x - 4)
Since, the graph of this function passes through (2, -2) also
-2 = p(2 + 5)(2 - 1)(2 - 4)
-2 = -p(14)
p = [tex]\frac{2}{14}[/tex]
p = [tex]\frac{1}{7}[/tex]
Therefore, equation will be,
f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]
The ratio of green bags to white bags in the store is equal to 2 to 5.There are 30 white bags in the store how many green bags are there?
Answers
Answer:
12 green bags
Step-by-step explanation:
Given data
The given ratio of green bags to white bags is
=2 to 5
=2:5
Number of white bags=30
Applying the part to part method, let the number of green bags be x
so
2/5=x/30
cross multiply
30*2=5x
60=5x
divide both sides by 5
x= 60/5
x=12
Hence there are 12 green bags

Phil left an estate valued at 140,000. In His will, he specified that his wife will get 25% more of his estate than his daughter. How much will his wife recieve?
Answers
Answer:
77,777.78
Step-by-step explanation:
The computation of the amount that would be received by his wife is shown below:
Let us assume the daughter would received x
So his wife would received 1.25x
The total estate value is 140,000
Now the equations would be
140,000 = x + 1.25x
140,000 = 2.25x
x = 62,222.22
So his wife would received
= 62,222.22 × 1.25
= 77,777.78
