Answer:

rise= -2 run= -4 slope= -1/2

Step-by-step explanation:

slope= rise/run

since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2

Answer:

f(- 7) = 17

Step-by-step explanation:

To evaluate f(- 7) substitute x = - 7 into f(x) , that is

f(- 7) = - 2(- 7) + 3 = 14 + 3 = 17

Answer:

x=5

Step-by-step explanation:

hey there

the angles given are corresponding angles meaning that they are congruent

so we set up an equation

23x-5=21x+5

step 1 subtract each side by 5

5-5 cancels out

-5-5=-10

now we have

23x-10=21x

step 2 subtract each side by 23x

21x-23x=-2x

now we have

-2x=-10

step 3 divide each side by 2

-10/-2=5

so we can conclude that

x=5

Answer:

B.

Step-by-step explanation:

it sounds about right to me. I'm not the best with math

Answer:

C

Step-by-step explanation:

∠ 5 and ∠ 8 are adjacent angles and are supplementary, sum to 180° , then

∠ 8 + ∠ 5 = 180°

∠ 8 + 45° = 180° ( subtract 45° from both sides )

∠ 8 = 135° → C

Answer: 12 hrs 40 mins

Step-by-step explanation:

The swimming time was 1 hour 25 minutes.

Her biking time was 5 hours longer than the swimming time so it was:

= 1 hr 25 mins + 5 hours

= 6 hours 25 mins

Her running time was 4 hrs 50 mins.

Add them all up to find the amount of time ran. First add up the minutes:

= 25 + 25 +50

= 1 hr 40 minutes

Hours = 1 + 6 + 4

= 11 hours

Total:

= 11 + 1 hr 40

= 12 hrs 40 mins

Answer:

Total surface = 102.4 cm^2 (second answer in the list of options)

Step-by-step explanation:

Notice that we need to add the surface of 4 rectangles, two have smaller sizes than the other two. A pair of rectangles are 7.2 cm x 4 cm = 28.8 cm^2, while the other pair has 7.2 cm x 2 cm = 14.4 cm^2

There are also two equal bases each one of size 4 cm x 2 cm = 8 cm^2

Now we add two of each of the individual surfaces discussed above to complete the total surface area:

2 * 28.8 + 2 * 14.4 + 2 * 8 =  102.4 cm^2

which agrees with the second answer option provided.

Answer:

15.4

Step-by-step explanation

From the diagram, we are given;

Adjacent = 12

Hypotenuse=x

Angle of elevation =39°

Using the SOH CAH TOA identity

Cos 39 = 12/x

x = 12/cos39

x = 13/0.7771

x = 15.44

Hence the value of x to nearest tenth is 15.4

Answer:

I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

Step-by-step explanation:

No trapezoid is attached; so, I will solve on a general note

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]

Using the attached image as a point of reference;

The parallel sides are: AD (6cm) and BD (12cm)

The height is 4cm

So, the area is:

[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]

[tex]Area = 18cm * 2cm[/tex]

[tex]Area = 36cm^2[/tex]

The first question where you have to write an equation it would be y=2/3x-5

these are the ones that you have to solve for y:

1. y=-3x

2.y=3

3. y=3/2x+5

I recommend you use desmos to graph them, it's pretty useful

Answer:

Step-by-step explanation:

i hope this helps :)

Answer:

(x, y) = (3, 3)

Step-by-step explanation:

[tex]x - 2y = - 3 \\ 2x + 2y = 12 \\ [/tex]

To apply the method of elimination, you must add the 2 equation if one of the variables is cancelled out. Luckily, the equations are already in a form where we can add them and y will be cancelled out.

[tex](x - 2y) + (2x + 2y) = - 3 + 12[/tex]

[tex]3x = 9[/tex]

[tex]x = 3[/tex]

Then we replace x on any equation to find y

[tex]x - 2y = - 3 \\ 3 - 2y = - 3 \\ - 2y = - 6 \\ y = 3[/tex]

so the solution is

x = 3 and y = 3
