What is the slope of the line, what does the slope represent? write an equation for emma’s graph x=time and y=distance
Answer:
5/2 or 2.5
Step-by-step explanation:
Slope formula:
(y₂ - y₁) / (x₂ - x₁)
Two points are given:
(2, 5) and (6, 15)
x₁ = 2
y₁ = 5
x₂ = 6
y₂ = 15
Substitute and solve:
(15 - 5) / (6 - 2)
10 / 4
5/2 or 2.5

If Triangle ABC~trIangle DEC, find the value of x and y."
Answer:
The right answer would be (D) x = 1.
Step-by-step explanation:
So since triangles ABC and DEC are congruent to each other, your gonna try to find the value of x. So from the figure we know that AB = 4x - 1, BC = 4, AC = 5, DE = x+2, CE = 4 and EC = 5. And since ΔABC ≅ ΔDEC the corresponding sides would be equal. And after, we will have :
AB = DE
4x - 1 = x + 2
4x - x =2 + 1
3x = 3
x = 1
So, as it shows, the value of x is one. So (D) x = 1 is the right answer. Hope this helped! :)
y is directly proportional to x. When y = 24, ,x=8. Work out the value of y when x=2
Answer:
When x = 2, y = 6
Step-by-step explanation:
Constant of Proportionality: y = kx
(24) = k(8)
24 = 8k
k = 3
y = kx ===> y = 3x
When x = 2:
y = 3x
y = 3(2)
y = 6

A bag contains 10 red, 3 blue, and 2 yellow marbles. If 3 marbles are selected one at a time with replacement, find the probability that all three are different colors
Answer:
4/225
Step-by-step explanation:
To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)
So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.
The probability of getting a red is:
10/15 = 2/3
The probability of getting a blue is:
3/15 = 1/5
The probability of getting a yellow is:
2/15
So to get all 3 different colors:
2/3 * 1/5 * 2/15 = 4/225

Answer:
I don't understand
Step-by-step explanation:
Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.4)(1.8)(−3.25) (-49)(-34)(-12)(-12) −1(3.5−7) How many expressions will have a product that is positive?
Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.

Seven less than 4 times the square of a number is 18. Find the two numbers.
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
