I used the pythagorean theorem on BAC triangle

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)

The length of BC is 15 units.

In the right triangle ABC.

we have AC = 8 units and AB = 17 units.

We need to find the length of BC using the Pythagorean theorem.

It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In the given right-angle triangle ABC.

We have,

AB = hypotenuse and the other two sides are AC and BC.

Applying the Pythagorean theorem.

We get,

[tex]AB^{2} = AC^2 +BC^2[/tex]

Now substitute AC = 8 and AB = 17.

[tex]17^2=8^2+BC^2\\289=64+BC^2\\BC^2=289-64\\BC^2=225\\BC=\sqrt{225}\\ BC=15 ~units.[/tex]

Thus, we have the length of BC as 15 units.

let's solve your equation step-by - step

-3-3/4(c-4)=5/4

Step 1: simplify both sides of the equation.

-3-3/4(c-4)=5/4

-3+-3/4 c+3=5/4 (distribute)

(-3/4 c)+(-3+3)=5/4 (combine like terms)

-3/4c=5/4

-3/4 c =5/4

Step 2: Multiply both sides by 4/(-3)

(4/-3)*(-3/4 c)=(4/-3)*(5/4)

Answer:c=-5/3

Answer:

10/10 - 7/10 = 3/10

Step-by-step explanation:

Muffins made = 12

Burnt muffins = 2

Good muffins = 12 - 2 = 10

Franco served 7/10 of the remaining muffins

Muffins served = 7/10 × 10

= 7

Muffins unserved = 10 - 7 = 3

Fraction of the non burned muffins remaining = non burned muffins - served muffins

= 10/10 - 7/10

= 3/10

The answer is B

Answer:

A

Step-by-step explanation:

when you substitute 4 in x and 3 in y, your result are 11 no 10

Answer:

The y intercept is (0,-3) The slope is 7/1 i think  

Answer:

(x-5)(x-6)

Step-by-step explanation:

when we look at something like this we have a, b, and c

a=1 (in front of x)

b=-11

c=30

our goal is trying to find factors of c that will give us b so in this case factors of 30 that will give us -11

so when you list all the factors of 30 you find that 6 and 5 both equal 30 when multiplied and add up to 11

but... we need -11 so if we change the signs both to negative that will give us a -11 when added and also a positive 30 when multiplied (-6)(-5)

so we then write it as (x-6)(x-5)

and if you FOIL that out you will end up getting the original equation :)

Answer:

-4

Step-by-step explanation:

count by a number line and you will see

Answer:

the answer is -4

Step-by-step explanation:

First you have to determine which sign is bigger. The number 8 is greater than 4 so we have to use the negative sign. now we can subtract or add. eight minus or plus four is four or twelve. so if we add or subtract the negative sign and the number four together we will get negative four or twelve. This is how you get the sum for negative four and eight. Hope this helps!

degree

The largest exponent in the polynomial is called the degree, and the coefficient of the variable raised to that exponent is called the leading coefficient. The constant in a polynomial has no variable written next to it.

Answer:

[tex](\frac{9}{2},-\frac{1}{2} )[/tex]

Step-by-step explanation:

Use the midpoint formula to find the midpoint of the line segment.

Answer:

M1= 62 M2= 45 M3= 24

Step-by-step explanation:

For angle 1:

180-118 = 62

Angle 2:

180- (73+62)

Angle 3:

part 1

180-73= 107

part 2

180-(107+49)= 24

Answer:

Step-by-step explanation:

You have to solve for 1 before you do anything.

<1 + 118 = 180                The two left angles are supplementary

<1 +118-118=180-118

<1 = 62

Now you can go after angle 2

<1 + 73 + <2  =  180         All triangles have 180 degrees

62 + 73 + <2 = 180         Combine the left

135 + <2 = 180                Subtract 135 from both sides.

135-135+<2 = 180-135     Combine

<2 = 45

Angle 3 is a little trickier because the angle you need to find <3 is not labeled.

73 + x = 180

x = 180 - 73

x = 107

NOw you can find <3

107 + 49 + <3 = 180

156 + <3 = 180

<3 = 180 - 156

<3 = 24

I have left out the reasons for <3. Maybe you can supply them.

Answer:

-1

Step-by-step explanation:

The mean is the sum of all values divided by the amount of values.

We take the sum of all the numbers:

-3 + -8 + 12 + -15 + 9

-11 + 12 + -15 + 9

1 + -15 + 9

10 + -15

-5

We then divide the sum by how many number we have (we are given 5 numbers):

-5/5 = -1

Therefore, our mean is equal to -1.

Answer:

-1

Step-by-step explanation:

-3 + -8 + 12 + -15 + 9 = -5 Now divide it by the amount of numbers given. -5 / 5 = -1

Answer:

The equation in a point-slope form that  represents their distance from

home, y miles, after x hours, is y - 110 = 55(x - 2)

Step-by-step explanation:

The point-slope form of the linear equation is

[tex]y-y_{1}=m(x-x_{1})[/tex] , where

m is the slope of the line (average)

[tex](x_{1},y_{1})[/tex] is a point on the line

→ The family is driving home  from vacation at an average speed

    of 55 miles per hour

∴ m = 55

→ After 2 hours they  are 110 miles from home

∵ x is the number of hours

∵ y is the distance in miles after x hours

∴ [tex]x_{1}[/tex] = 2

∴ [tex]y_{1}[/tex] = 110

→ Substitute these values in the form of the equation above

∴ y - 110 = 55(x - 2)

The equation in a point-slope form that  represents their distance from

home, y miles, after x hours is y - 110 = 55(x - 2)

Step-by-step explanation:

3−2(x+1)=2x−7

3+(−2)(x)+(−2)(1)=2x+−7(Distribute)

3+−2x+−2=2x+−7

(−2x)+(3+−2)=2x−7(Combine Like Terms)

−2x+1=2x−7

−2x+1=2x−7

Step 2: Subtract 2x from both sides.

−2x+1−2x=2x−7−2x

−4x+1=−7

Step 3: Subtract 1 from both sides.

−4x+1−1=−7−1

−4x=−8

Step 4: Divide both sides by -4.

−4x−4=−8−4
