Answer: -1.25

Step-by-step explanation:

You can use a graph to help. Plot the points first, then draw a line through them. Then, count the points that rise, over the amount of points that run.

You can also do it the computational way without a graph.

Use this equation:

m = (y2 - y1) / (x2 -x1)

Answer:

[tex]2x\leq -18[/tex]

Step-by-step explanation:

[tex]2x \leq -18[/tex]

the first side is

twice x

2 times x

the symbol means less than or equal to

and finally we have the -18

Answer:

2x<_-18

Step-by-step explanation:

Twice means 2x and less than means <_ and -18

Answer:

12f + 9.8g + 5.7 centimeters

Step-by-step explanation:

Side A = (9.8f-8.4) centimeters

Side B = (2.2f+4.9) centimeters

Side C = (9.8g+9.2) centimeters.

Perimeter of a triangle = Side A + Side B + Side C

= (9.8f-8.4) + (2.2f+4.9) + (9.8g+9.2)

= 9.8f - 8.4 + 2.2f + 4.9 + 9.8g + 9.2

Collect like terms

= 9.8f + 2.2f + 9.8g - 8.4 + 4.9 + 9.2

= 12f + 9.8g + 5.7 centimeters

Therefore, the expression which represents the perimeter of the triangle 12f + 9.8g + 5.7 centimeters

Answer:

- 23

Step-by-step explanation:

We could do this the long way and expand the whole product or note that the [tex]a^{4}[/tex] terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is

4a³ × 3a = 12[tex]a^{4}[/tex]

+ 5a² × - 7a² = - 35[tex]a^{4}[/tex]

Summing gives

12[tex]a^{4}[/tex] - 35[tex]a^{4}[/tex] = - 23[tex]a^{4}[/tex]

with coefficient - 23

The only pairs that will give you some multiple of [tex]a^4[/tex] are:

[tex]4a^3\cdot (3a),\quad 5a^2\cdot(-7a^2)[/tex]

their values are respectively

[tex]12a^4,\quad -35a^4[/tex]

and their sum is [tex]-23a^4[/tex]

Answer:

  C.  No, because AB is Two-fifths the length MN but CD is One-third the length QP.

Step-by-step explanation:

Dilation multiplies each coordinate or length by the scale factor. Here, different corresponding lengths are multiplied by different values, so no dilation is involved.

__

Additional comment

Dilation shouldn't change any slopes, so if slopes of corresponding segments are different, that is another indication dilation is not involved. (No figure is supplied here, so we cannot judge slopes.)

Answer:

x = 1.73

y = 2.45

z = 1.41

Step-by-step explanation:

1/z = z/2

z^2 = 2

z = sqrt(2)

1^2 + z^2 = x^2

1 + 2 = x^2

x^2 = 3

x = sqrt(3)

z^2 + 2^2 = y^2

2 + 4 = y^2

y^2 = 6

y = sqrt(6)

x = 1.73

y = 2.45

z = 1.41

Answer:

x=3

Step-by-step explanation:

The definition of the side splitter theorem is if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally.  

What that means in this problem is that

x/18=9/54

Now, we just have to simplify that by cross multiplying

54x= 162

x=3

Answer:

15

Step-by-step explanation:

you basically have to multiply -3 by x to get y

-3·(-3)=9

-7·(-3)=21

so -5·(-3)=15

Answer:

4. 5. 3. are correct im pretty sure

Step-by-step explanation:

Statements 1, 2, and 3 about f(x) and g(x) are "true".

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.

x  : 1   3   5   7   9

g(x): 3  7   11   15   19

Here the slope of the function g(x) is 2.

This means statements 1 and 2 are false because slopes are different.

To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.

Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.

The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.

To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.

Therefore, the true statements are 2, 3, and 4.

Answer:

A. 10 + 2

Step-by-step explanation:

288 ÷ 24 is shown below. 240 ÷ 24 = 10 288 – 240 = 48 48 ÷ 24 = 2

After obtaining the quotient of 288 ÷ 24 = 10,

Multiplying the divisor 24 by 10 = 240 and subtracting 240 from 288 to obtain the remainder = 48, the divisor is again used in 48 and the quotient obtained is added to the intula quotient value of 10 ; (10 + 2) and the process repeated

Answer:

x=-2, 2.

Step-by-step explanation:

5x^2-20=0

factor out the 5

5(x^2-4)=0

5(x+2)(x-2)=0

(x+2)(x-2)=0/5

(x+2)(x-2)=0

x+2=0, x-2=0

x=0-2=-2,

x=0+2=2.
