how do you graph/ solve quadratic equations

Answer:

35 degrees

Step-by-step explanation:

Sum of angles inside a triangle is 180 degrees.

Right angle is 90 degrees.

180 = 90 + (x + 46) + (x + 66) = 2x + 202

x = -11

A = x + 46 = -11 + 46 = 35

Answer:

7 W + 4w - 6

Step-by-step explanation:

Answer: y = -4x

Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

Answer:

42

Step-by-step explanation:

in order to find y, we need to find x.

180-65-62=53

x=53

we need to subtract 53-?=11

53-42=11

y=42

Answer:

42

Step-by-step explanation:

because the triangles are congruent, we can place the angle x in CDE to solve for it. Knowing the sum of all angles in a triangle is 180, we can set up the formula below.

62 + 65 + x = 180

Additionally, because the triangles are congruent, we know that the length of CD is equal to GH, letting us set up this formula:

x - y = 11

Solving the first formula, we now know the value of x, 53.

62 + 65 + 52 = 180

Plugging that into the second formula and solving, we get 42.

53 - 42 = 11

Answer:The number of text messages sent by his sister=162

Step-by-step explanation:

Step 1

The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister =4 to 9= 4:9

Number of text messages sent by Lucas =72

Total ratio is given as 4+ 9= 13

Step 2

such that the total number of messages sent by Lucas and by his sister will be calculated as

Ratio of text messages sent by Lucas/  total ratio x Total messages  = Number of text messages sent by Lucas . Let X = Total number of messages  

4/13 x X = 72

X=72  x 13 / 4 =234

Therefore, The number of text messages sent by his sister= ratio of  text messages sent by his sister/ Total ratio x Total number of messages  =

9/13  X 234= 162 messages

It's around (-4. 5, 1.5). It's somewhere in that range.

Answer:

√35i

Step-by-step explanation:

i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.

Answer:

We know that √-1 = i, where "i" is the imaginary unit

± √(-35) = ± √(35) i

Answer:

The percentage increase is 64%

Step-by-step explanation:

Answer:The percentage increase is 64%

Step-by-step explanation:

Answer:

5) Slope(m): 2

y-intercept(b): (0, 4)

6) Slope(m): -1

y-intercept (b): (0, -6)

7) Slope(m): 5

y-intercept (b): (0, 8)

8) Slope(m): 7

y-intercept (b): (0, 1/2)

Step-by-step explanation:

in order to find the slope and y-intercept you need to rewrite the equation in y=mx+b.

in 5, the equation is -2x+y=4. we need to add 2x to both sides to get y=2x+4. now you can find your slope (2) and your y-intercept point (0, 4)

in 6, the equation is x+y=6. we need to subtract x from to both sides so we get y=-x+6. you would get a slope of -1 and a y-intercept point of (0, 6)

in 7, the equation is -5x=8-y. we need to add 5x to both sides to get 0=8-y+5x. then add y to both sides so we get the equation y=5x+8. you have a slope of 5 and a y-intercept point of (0, 8)

in 8, the equation 0=1-2y+14x. we need to add 2y to both sides and we get 2y=14x+1. since we need y to stand alone we need to divide both sides by 2. now we have y=7x+1/2. the slope is 7 and the y-intercept point is (0, 1/2)

Hope this helps!! :)

Answer:

its 34

Step-by-step explanation:

46

For the first two use the formula [tex]A^2 + B^2 = C^2[/tex]

[tex]15^2 + 36^2 = C^2(unknown)[/tex]

Calculate 15 x 15 + 36 x 36 = 1521

Now its

1525 = C^2

Fins the squeare root of 1521 whitch is 39

and square c^2 as well whitch make it C^1 or simple C

This give us a final anwser of the missing side

39 = C

Second triangle

For this the formual is different since we are not finding the lenght of the hypotunus (C), we know this becauee the missing angle is met my a 90 digree angle.

Here the equasion is  C^2 - A^2 = B^2

WE will it in again

15^2 - 9^2 = B^2

Calaulate 15 x 15 - 9 x 9 = 144

Now its 144 = B^2

Again we find the square root for each side

Square root of 144 is 12

and Square root of B^2 is Simpley B

We put in togethe to find the final anwser whitch is

12 = B

For the last two it is simple

All angles of a triangle added together must always equal 180 degrees

So it the two side are 75 and 32 we add them (75+32) to get 107

Now we just subtract that amount (107) form 180 to get the third missing angle. 180 - 107 = 73  

Here the missing angle is 73

One way to know if this is correct is to add all side and see if it equaels 180

75 + 32 + 73 = 180

For the second question it seems to be exactly the same as the first in the photo so the anwser would also be 73.

Hope this helps! :)

Answer:

Step-by-step explanation:

volume of sphere = 4πr³/3 = 972π in³

r³ = 729 in³

r = 9 in

The value of its radius is,

⇒ r = 6.14 inches

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The volume of this sphere is 972 pi cubic inches.

Now, We know that;

Volume of sphere is,

⇒ V = 4/3πr³

⇒ 972 = 4/3 × 3.14 × r³

⇒ 972 × 3 = 12.56 × r³

⇒ r³ = 232.16

⇒ r = ∛232.16

⇒ r = 6.14 inches

Thus, The value of its radius is,

⇒ r = 6.14 inches

y=-12/11

Since the slope equals 0, then the line is horizontal.
