show work! my teacher told me this was wrong, what's the correct answer?​

Functions can be represented on graphs and vice versa.

It is true that point (4,-2) is on the graph of [tex]y = -0.5x[/tex] i.e. the statement is Yes

The function of the graph is given as:

[tex]y = -0.5x[/tex]

To determine if the point (4,-2) will fall on the graph, we simply substitute 4 for x in the given function.

[tex]y = -0.5\times 4[/tex]

[tex]y = -2[/tex]

The y value for (4,-2) is -2, and the calculated y value for [tex]y = -0.5x[/tex] when x = 4 is -2.

Hence, it is true that point (4,-2) is on the graph of [tex]y = -0.5x[/tex]

Answer:

B

Step-by-step explanation:

In B, the lines are parallel meaning they will never intersect and have no solution. However, in C you can tell that the lines will intersect eventually so it does have a solution.

Answer:

B

Step-by-step explanation:

From the picture I can see you crossed out A and D, which only leaves B and C. If we extrapolate the graph at C the lines are eventually going to intersect, whereas in B the lines are going in parallel against each other, meaning there will never be an intersection between the two. So B would represent a system of equations with no solutions.

Answer:

y = x+4

Step-by-step explanation:

First, we find the slope

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

m = ( 9-7)/(5-3)

    = 2/2

   =1

Slope intercept form of a line is y = mx+b  where m is the slope and b is the y intercept

y = 1x+b

Using one of the points

7 = 1*3+b

7 = 3+b

4=b

y = x+4

Answer:

A = 15u²

Step-by-step explanation:

Area of a Trapezoid Formula:

Plug in our values (h = 3, b1 =  7, b2 = 3)

[tex]\frac{3}{2}*(7+3)[/tex]

Now we evaluate

[tex]\frac{3}{2}*(10)[/tex]

[tex]\frac{30}{2} = 15[/tex]

Answer: 1/4

Step-by-step explanation:

Noon is 12:00

Supposing that each number is one hour

15 minutes = 1/4 hrs

And therefore 12:15 PM is represented as 1/4

Let the ceilings be a & b

and the distance from one corner of the ceiling to the opposite be c

then using Pythagoras theorem

[tex]c = \sqrt{a {}^{2} + b {}^{2} } \\ c = \sqrt{16 {}^{2} + 12 {}^{2} } \\ c = \sqrt{256 + 144 } \\ c = \sqrt{400} \\ c = 20[/tex]

hence ,c .°. the distance from one corner of the ceiling to the opposite is 20

Answer:  Graph is below

=============================================================

Explanation:

We divide both sides by -4 to isolate p. This will flip the inequality sign.

-16 > -4p

-16/(-4) < -4p/(-4)

4 < p

p > 4

The graph has an open hole at 4 and shading to the right. See below.

The solution of the inequality - 16 > - 4p is shown in number line as given below in figure.

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Given that;

The inequality is,

⇒ - 16 > - 4p

Now, Solve the inequality as;

⇒ - 16 > - 4p

Multiply by -1;

⇒ 16 < 4p

Divide by 4;

⇒ 4 < p

Thus, The solution of the inequality is,

⇒ 4 < p

Answer:

10/14 - 7/14 = 3/14 :D

Step-by-step explanation:

you have to find the common denominator, in this case its 14. then, whatever number you multiplied the denominator by, you have to multiply the numerator by. so, 5/7x2= 10/14, and 1/2x7 = 7/14, then its just 10-7 which equals 3

The location of the treasure on the treasure map is (b) (7.6,8.8)

The ratio is given as:

[tex]m : n = 5 : 9[/tex]

The coordinates of the rock and the tree are:

[tex]Rock =(3,2)[/tex]

[tex]Tree = (16,21)[/tex]

The x and y coordinates of the location of the treasure are:

[tex](x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

So, we have:

[tex](x,y) = (\frac{5 \times 16 + 9 \times 3}{5 + 9},\frac{5 \times 21 + 9 \times 2}{5 + 9})[/tex]

[tex](x,y) = (\frac{107}{14},\frac{123}{14})[/tex]

[tex](x,y) = (7.6,8.8)[/tex]

−5.8+d>43/4

Step-by-step explanation:

The inequality represents the situation as −5.8+d>434.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Given that Elizabeth lives on a straight road that goes east and west. She starts from a point 5.8 miles west of her home and drives a certain distance to the store. The store is more than 434 miles east of her home.

The inequality will be written as the algebraic sum of the distance d and 5.8 is greater than the 434 miles.

Answer:

Area = 6cm^2

Step-by-step explanation:

Pythagorean Theorem = [tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]a^{2} + 3^{2} = 5^{2}[/tex]

or

[tex]a^{2} + 9 = 25[/tex]

Subtract 9 from 25.

25 - 9 = 16

Square root 16 to get 4.

a = 4

Now to find the area.

Area = 1/2(3*4)

12/2 = 6

The length and width of a rectangular field fully enclosed with 218 metes fencing  are 63 meters and 46 meters respectively.

The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:

where

l = length

w = width

perimeter = 218 meters

The length of the field is  17 meters longer than the width, w. Therefore, the length is defined as follows:

The length and the width can be calculated as follows:

218 = 2(l + w)

218 = 2(17 + w + w)

218 = 34 + 4w

218 - 34 = 4w

184 = 4w

divide both sides by 4

w = 184 / 4

w = 46 meters

length = 17 + 46

length = 63 meters
