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

Step-by-step explanation:

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

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 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.

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.

In a triangle ABC the value of side a is 13.12 cm.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in a ΔABC, a/sinA = b/sinB = c/sinC.

GIven, In a ΔABC A = 29°, B = 36°, b = 15.8 cm.

∴ a/sinA = b/sinB.

a/sin(29°) = 15.8/sin(36°).

a/0.49 = 15.8/0.59.

a = (15.8×0.49)/0.59

a = 7.742/0.59.

a = 13.12.

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

20 + n(M∩C) + 24 - 3n(C∩P∩M) = 32

n(M∩C) = 3n(C∩P∩M) - 12 - *

We know,

Answer:

Step-by-step explanation:

We can rewrite the equation as [tex]y=0x+9.5[/tex].

Comparing this to slope-intercept form, the slope is 0 and the y-intercept is 9.5.

The first system of equations has no solution and the second set of equations has a unique solution.

If we are having two equations as

[tex]a_{1} x^{2} +b_{1} x+ c_{1} =0[/tex]

and [tex]a_{2} x^{2} +b_{2} x+ c_{2} =0[/tex]

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

[tex]\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } =\frac{c_{1} }{c_{2} }[/tex]

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

[tex]\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } \neq \frac{c_{1} }{c_{2} }[/tex]

For, the 26th question, we have

4x +8y = -8

4x +8y +8 = 0

x +2y +2 =0 equation(1)

x =-2y +1

x +2y -1 = 0 equation(2)

On comparing these equations with the general form, we have

[tex]a_{1} = 1, a_{2} =1\\b_{1} = 2, b_{2} = 2\\c_{1} = 2, c_{2} = -1[/tex]

So, [tex]\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } \neq \frac{c_{1} }{c_{2} }[/tex]

Thus, this system of equations has no solution.

Now, For the 27th question, we have

2x - 3y = 6

2x -3y -6 = 0 equation(3)

[tex]y = \frac{2}{3}x -2 \\\\3y = 2x -6\\\\3y -2x +6 = 0[/tex] equation (4)

On comparing these equations with the general form, we have

[tex]a_{1} = 2, a_{2} =3\\b_{1} = -3, b_{2} = 2\\c_{1} = -6, c_{2} = 6[/tex]

So, [tex]\frac{a_{1} }{a_{2} } \neq \frac{b_{1} }{b_{2} }[/tex]

Angles ∠4 and ∠6 are the same side interior angles.

Interior angles are defined as the inner of two angles formed when two sides of a polygon intersect. Any of the four angles are formed when a third line intersects a pair of parallel lines.

If two angles are on opposite sides of a transversal, they are alternate. A transversal is a line that runs parallel to two horizontal lines. The alternate angles are alternate interior angles if they are located between the two parallel lines. The alternate angles are alternate exterior angles if they are located outside of the two parallel lines.

Angles ∠4 and ∠6 are known as alternate interior angles based on the information provided. As a result, you have the following options:

They are located on opposing sides of the transversal.

They are located between the two lines crossed by the transversal.
