What are the next numbers on the ratios chart
The equivalent ratios are 14:56 and 5 : 20 .
A ratio in mathematics shows how many times one number appears in another. For instance, if there were eight oranges and six lemons on a fruit platter, the ratio of oranges to lemons would be eight to six.
By dividing each quantity by the sum of all the numbers' common components, ratios can be reduced (much like fractions are). The fraction is said to be in its simplest form when the ratio's numbers are the tiniest practical integers.
A and B are frequent names for the ratio's antecedent and consequent, respectively.
The given ratios are 2 : 8 and 7 : 28 . which when simplified given the ratio 1 : 4 .
Now we know that 1 / 4 = k which is the common ratio.
Hence 14 / x = k = 1 / 4
or , x = 56
Again 5 / y = k = 1 / 4
or , y = 20
Therefore the equivalent ratios are 14:56 and 5 : 20 .

Write an equation of a line that passes through (-1,3)and (1,4)
SOLUTION
We want to write an equation of a line that passes through (-1,3) and (1,4)
First, let us find the slope m of the line for the points (-1,3) and (1,4)
We have
[tex]\begin{gathered} m=\frac{4-3}{1-(-1)} \\ m=\frac{1}{1+1} \\ m=\frac{1}{2} \end{gathered}[/tex]Now, equation of a line in point slope form becomes
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ (x_1,y_1)=(-1,3) \end{gathered}[/tex]plugging in the values, we have
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ y-3=\frac{1}{2}(x-(-1) \\ y-3=\frac{1}{2}(x+1) \\ y-3=\frac{1}{2}x+\frac{1}{2} \\ y=\frac{1}{2}x+\frac{1}{2}+3 \\ y=\frac{1}{2}x+\frac{7}{2} \end{gathered}[/tex]Hence the answer becomes

An equation of the function in standard form for the given table of values is equal to -2x² - 7x - 6 = 0.
The standard form of a quadratic equation.In Mathematics, the standard form of a quadratic equation is given by;
y = f(x) = ax² + bx + c = 0
In order to write an equation of the quadratic function in standard form, we would formulate a system of equations from the data provided in the table above as follows:
-6 = a(-3)² + b(-3) + c ⇒ -6 = 9a - 3b + c .......equation 1.
0 = a(-2)² + b(-2) + c ⇒ 0 = 4a - 2b + c .......equation 2.
-2 = a(-1)² + b(-1) + c ⇒ -2 = a - b + c .......equation 3.
From equation. 2, we derive:
c = -4a + 2b .....equation 4.
Substituting equation 4 into equation 1 and 3, we derive the following equations:
-2 = a - b - 4a + 2b ⇒ -2 = -3a + b
-6 = 9a - 3b - 4a + 2b ⇒ -6 = 5a - b
By using the elimination method, the value of a is given by:
[-2 + (-6) = (-3a + 5a) + (b + (-b)]
-2 - 6 = -3a + 5a + b - b
-8 = 2a
a = -4
Next, we would determine the value of b as follows:
-2 = -3a + b
b = -2 + 3a
b = -2 + 3(-4)
b = -2 - 12
b = -14
For the value of c, we have:
c = -4a + 2b
c = -4(-4) + 2(-14)
c = 16 - 28
c = -12.
Substituting the respective values of a, b and c into the standard form of a quadratic equation:
ax² + bx + c = 0
-4x² - 14x - 12 = 0
Dividing all through by 2, we have the following quadratic function:
-2x² - 7x - 6 = 0

b) The y-intercept is marked at y = 1 on the y-axis.
c) Using the slope and the intercept, point (3,3) is the second point used to graph the function.
d) The graph of the linear function y = 2/3x + 1 is given at the end of the answer.
What is the definition of a linear function in slope-intercept format?A linear function, in slope-intercept format, is modeled as follows:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, the function is:
y = 2/3x + 1.
Then, form item a, we have that:
The slope is of m = 2/3.The intercept is of b = 1.For item b, the y-intercept of b = 1 means that the function crosses the y-axis at b = 1.
For item c, we have to consider that the slope is of 2/3, meaning that when y increases by 2, x increases by 3. Point (0,1) is on the graph of the function, hence point (3,3) will also be, as x increases by 3 from 0 to 3 and y increases by 2 from 1 to 3.
Considering the discussion above, the graph of the function is given at the end of the answer, with the intercept and point (3,3) labeled.

What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For the given linear relationship, we have two points, as follows:
(5,2000) and (8,3500).
The slope is given by change in y divided by change in x, hence:
m = 1500/3 = 500.
Then:
y = 500t + b.
When t = 5, y = 2000, hence we solve for the intercept as follows:
2000 = 500(5) + b
b = -500.
Then the function is:
y = 500t - 500.
For 4500 units, the time is found as follows:
4500 = 500t - 500
500t = 5000.
t = 5000/500
t = 10 hours.

Two cars start moving from the same point. One travels south at 16 mi/h and the other travels west at 12 mi/h. At what rate (in mi/h) is the distance between the cars increasing three hours later?
Answer:
20 mi/h
Step-by-step explanation:
You want the speed of separation after 3 hours between two cars that started from the same point. One is moving at 16 mi/h south, the other is moving at 12 mi/h west.
Velocity vectorsSince both cars started from the same point, the speed of separation is the magnitude of the difference between the respective velocity vectors. A graphical representation of the velocity vectors shows them to be the legs of a right triangle. Their difference is the length of the hypotenuse, which can be found using the Pythagorean theorem.
s = √(16² +12²) = √(256 +144) = √400
s = 20
The speed of separation is a constant 20 mi/h.
__
Additional comment
If the cars did not start at the same point, then the speed of separation would be changing with time. It could be found using the derivative of the distance between the cars, or by considering the car speeds in the direction each car is from the other at the time of interest.
We note that the problem here makes use of a 3-4-5 right triangle, with a multiplier of 4 mph.

I added a picture of my question need answer quickly please
The statements that are true regarding the temperature include:
1. At noon, the temperature is - 9 1/2°F.
2. The temperature at 5pm is - 15 3/4°F.
3. The change in temperature from noon to 5pm is - 6 1/4°F.
How to calculate the temperature?From the information, the temperature at 6A.M is -14°D and the temperature increases at an average of 3/4°F each hour until noon. Then it drops at 1 1/4°F until 5P.M.
The temperature at noon will be:
= -14 + (3/4 × 6)
= -14 + 4.5
= -9.5°F
The temperature at 5pm will be:
= -9.5 - (1 1/4 × 5)
= -9.5 - 6.25
= -15.75
The total change in temperature will be:
= Ending temperature - Starting temperature
= -15.75°F - (-14°F)
= 1.75°F
The temperature change from noon to 5 pm will be:
= -15.75 - (-9.5)
= -6.25 = 6 1/4°F
