Answer:
9/14 (9 over 14)
Explanation:
The “slope” is the gradient of the line connecting the two points.
We find the gradient by doing (the change in the y-values) divided by (the change in the x-values).
In this case, we would have -9 (the difference between -1 and -10) divided by -14 (the difference between 7 and -7) which gives 9/14 (9 over 14).
This is equal to 0.643 (to 3 decimal places) if it want it as a decimal.

In the diagram below, GH is parallel to DE. If the length of DE is the same as the
length of GF, DF = 13, and GH = 5, find the length of GF. Figures are not
necessarily drawn to scale. State your answer in simplest radical form, if necessary.
Answers
Using the properties of similar triangle and parallel lines we calculate the length of GF as √65 units.
It is given that GH is parallel to DE or GH || DE in the trapezium GHDE .
Therefore in the triangles ΔFDH and ΔFDE , we can say that
ΔFDH is similar to ΔFDE by angle angle angle axiom of similarity.
Now using the properties of similar triangles we can say that :
FG / DF = GH / DE
Now let us consider the length of GF be x.
Therefore DE = x
Now using the properties of similar triangles and substituting the values we get:
x / 13 = 5 / x
or, x² = 65
or, x = √65
Therefore the length of DE and GF is equal to √65.

If you are given a continuous function that has a domain of [-3, 4] which of the following values are included in the given domain?
Answers
A continuous function that has a domain of [-3, 4] will include all the values as -3,-2,-1,-0,-1,-2,3,4
What do you mean by continuous function?
In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities, or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter. Any function that is not continuous is said to be discontinuous.
It is given that a continuous function has a domain of [-3,4]
According to the definition of closed interval,
[-3,4] will contain all the elements between them and including them.
Therefore, [-3,4] will contain elements as -3,-2,-1,-0,-1,-2,3,4
Hence, a continuous function that has a domain of [-3, 4] will include all the values as -3,-2,-1,-0,-1,-2,3,4

Find
a) F (10)
6) F(-3)
Answers
The value of f(10) = 107 and f(-3) = 16.
The function is defined as in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). An example of this would be y=x2. You only get one output for y if you enter anything for x. Considering that x is the input value.
Given that f(x)=x² + 7
We do determine the values of F (10) and F(-3)
Now f(10)
= (10)2 +7
= 100 +7
= 107
Now f(-3)
= (-3)2 +7
= 9 +7
= 16
Therefore the value of f(10) = 107 and f(-3) = 16

bobby spent 40% of his allowance on art supplies last month, with two-thirds of this amount spent on paintbrushes alone. if his monthly allowance is $75, how much did bobby spend on paintbrushes last month?
Answers
Bobby spent $20 out of $75 of his monthly allowance on paintbrushes.
What is monthly allowance?
Giving someone money on a regular basis to help them pay for the things they need is known as giving them an allowance.
Main Body:
total monthly allowance = $75
Now Bobby spent 40% on his art supplies,
which means we need to calculate 40% of 75.
⇒(40/100)*75
⇒30
so Bobby spent $30 on art supplies.
now according to question,
Bobby spent 2/3 on paintbrushes
⇒2/3 of art supplies
⇒(2/3 )*30
⇒$20
Hence Bobby spent $20 on his paintbrushes.

The fraction 3/5 fits into 2 1/5 more or less than 1? That means the quotient is more or less than 1?
Answers
The fraction 3/5 fits into 2 1/5 more than once. The quotient is more than one.
We are given two fractions. The first fraction is 3/5, which is a simple fraction. The second fraction is 2 1/5, which is a mixed fraction. We will first convert the mixed fraction into a simple fraction.
F = 2 1/5
F = (2*5 + 1)/5
F = 11/5
We need to find out if the quotient is more or less than one. So we will divide the second fraction by the first fraction. Let the quotient be represented by the variable "Q".
Q = (11/5)÷(3/5)
Q = (11/5)×(5/3)
Q = 11/3
Q = 3.667
We can see that the quotient is more than one. Hence, the fraction 3/5 fits into 2 1/5 more than once.

The condition at which these equations will have infinitely many solutions is

I'm going to assume that this is asking you to graph in Slope-Intercept form, but if I am mistaken, comment on my answer and I will happily change it.
Slope-Intercept form:
y = mx + b
You leave y and x as variables, while m and b are to be substituted for slope and y-intercept. y-intercept is when x=0, where a point on a line is on the y axis.
To help you learn, for example, we have an equation is slope-intercept form:
y = 8x + 3
In this case, the slope is 8 and the y intercept is 3 as m is the slope and b is the y-intercept.
The slope is the steepness of the graph. The value of the slope is how much the y-value increases if the x-value increases by 1.
We can find the slope from 2 points using this formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we plug in our points into the formula.
[tex]\frac{-2-3}{5-5}[/tex]
Simplify.
[tex]\frac{-5}{0}[/tex]
Anything divided by 0 is undefined. This means the line we are graphing is completely vertical, known as undefined. We can only get this if the x value stays the same no matter what. In this case, the x value stays the same when the y value changes, meaning a undefined slope.
We have a special case here. If the slope is undefined, we do not use y = mx+b. Instead, we use:
x = what the x values of the 2 points are
x values of both points: 5
x = 5

The alternate angles are alternate interior angles if they are located between the two parallel lines.
