The difference of the two solutions of x^2+19x+c=0 is 15. Find the solutions.

Answer:

2

Step-by-step explanation:

The equation is mx+b=y

The equation is not simplified yet.

2y-4x=1

Add 4x to both sides

2y=1+4x

Divide by 2

1/2+2x

For this just identify. M=slope. The number next to the x is 2. So the answer is 2

Answer:

Slope is 2: y = 2x + 1/2

Step-by-step explanation:

2y - 4x = 1

    + 4x   + 4x (Add 4x to both sides to leave y by itself on one side)

------

2y/2 = 4x/2 + 1/2 (Divide both sides by 2 in order to leave y with no coefficient)

y = 2x + 1/2

Answer:

The length of the slide is 10 feet.

Step-by-step explanation:

To find the length of the slide you have to use the formula:

a^2 + b^2 = c^2 (^2 means squared)

In this case:

a= 6 and b=8 c= unknown

6 squared (6 times 6) is 36

8 squared (8 times 8) is 64

Add these two numbers to get:

36+64=100

6^2+8^2=100

However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.

What number times itself equals 100? 10.

The length of the slide in 10 feet.

Answer: -4

Step-by-step explanation: Hopefully I put the right answer, the question is worded a bit weird, if it's not please let me know.

-12 - 8 = -4

It's still negative because the positive number is not equal nor greater than the negative number so it's still negative.

Answer:

x = 1

Step-by-step explanation:

Triangle ABC is congruent to Angle DEF

13x - 12 = 7x - 6

6x = 6

x = 1

Answer:

x = 1

Step-by-step explanation:

These are congruent triangles

The single line is the same length in ABC as the single line in DEF

The double line is the same length in ABC as the double line in DEF

13x-12 is the same length as 7x-6

13x-12 = 7x-6

Subtract 7x from each side

13x-12 -7x =7x-6 -7x

6x-12 =-6

Add 12 to each side

6x-12+12 = -6+12

6x = 6

Divide each side by 6

6x/6 = 6/6

x = 6/6

x = 1

Answer:

no solution

Step-by-step explanation:

lets isolate the absolute value first:

so

|x|-8+8=-2-8

|x|=-10

since absolute value cannot be less than -10, there is no solution.

Hope this helps!

The equation |x+8|=−2 has no solution because the absolute value of a number cannot be negative.

The equation |x+8|=−2 does not have a solution because the absolute value of a number is always non-negative, and it cannot equal a negative number. The absolute value represents the distance from zero on the number line, and distance cannot be negative. Thus, the equation |x+8|=−2 is inconsistent because it implies that a non-negative quantity (the absolute value) is equal to a negative number (−2), which is not possible.

When solving equations involving absolute values such as |x| = a, if 'a' is positive, then the solutions are x = a or x = -a, because both distances a and -a from zero have the same absolute value. However, if 'a' is negative, the equation has no solution, as the absolute value cannot take on negative values. If you encounter an absolute value equation set to a negative number, you can immediately conclude that there are no solutions.

Answer:

340 phones

Step-by-step explanation:

Make an expression

She repairs 10 phones each day, d.

Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.

450-10d

We want to find how many she has left after 11 days, so we can substitute 11 in for d

450-10(11)

Multiply

450-110

340

She will still have 340 phones left to repair

Katie would have repaired 110 phones by the end of the 11th day. She started with 450 phones, so after subtracting the number of repaired phones, she has 340 phones left to repair.

To determine the number of phones Katie has left to repair at the end of the 11th day, we need to calculate how many phones she has repaired so far. Since Katie repairs 10 phones every day, after 11 days, she will have repaired 10 phones/day * 11 days = 110 phones.

Katie starts with 450 phones at the beginning of the month. So, to find out how many are left un-repaired, you subtract the number of phones she has repaired from the starting amount.

Therefore, 450 phones - 110 phones = 340 phones are left to repair at the end of the 11th day.

Answer:

no solutions

Step-by-step explanation:

A linear equation having same variable term on both RHS and LHS is not defined. The number of solutions for the equation 5 - 2x = 3 + x - 4 - 3x is zero.

A linear equation is can be defined as a equation that has its degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given equation is as below,

5 - 2x = 3 + x - 4 - 3x

It can be simplified as,

5 - 2x = 7 - 2x

Since both LHS and RHS contain the same variable term 2x which can be cancelled out so that there will be no variables.

Thus, the given equation has no solutions.

Hence, the number of solutions for the given equation is zero.

Answer:

x < 1

Step-by-step explanation:

To solve for x, we need to get x by itself

2(5 - x)>8

Distribute the 2

2*5 -2*x >8

10- 2x >8

Subtract 10 from both sides

10-10 -2x >8 -10

-2x > -2

Divide both sides by -2

-2x/-2> -2/-2

Since we divided by a negative number, we must flip the inequality sign

x < 1

Answer:

x < 1

Step-by-step explanation:

Given

2(5 - x) > 8 ( divide both sides by 2 )

5 - x > 4 ( subtract 5 from both sides )

- x > - 1

Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

x < 1

Answer: XYZ = 144 degree

Step-by-step explanation:

The non overlapping angles are said to be adjacent angles of a common vertex and a common side but do not overlap.

If WYZ has a measure of 32 degree.

And XYW has a measure of 112 degree

Then, the measure of XYZ will be

XYZ = WYZ + XYW

XYZ = 32 + 112

XYZ = 144 degree

Add b to both sides

[tex]9,000-b+b=b+b-11,000\\9,000=2b-11,000[/tex]

add -11000 on both sides

20000=2b

divide by 2 on both sides

b=10000

Answer:

[tex]x = \dfrac{36}{y}[/tex]  

Step-by-step explanation:

We are given the following in the question:

x and y vary inversely.

[tex]x\propto \dfrac{1}{y}[/tex]

Removing the sign of proportionality and adding the constant of proportionality, we get,

[tex]x = k\times \dfrac{1}{y} = \dfrac{k}{y}[/tex]

where k is the constant of proportionality.

When x = 3, y = 12

Putting these value in the equation, we get,

[tex]3 = \dfrac{k}{12}\\\\\Rightarrow k = 12\times 3 = 36[/tex]

Putting value of k, we get,

[tex]x = \dfrac{36}{y}[/tex]

which is the required equation to model the given situation.

7x3 = 21

7+3 = 10

7-3 = 4

It's the same process for the (9)(4) = 36135

So for (8)(5) would be:

8x5=40

8+5=13

8-5=3

(8)(5)= 40133

Answer:

40133

Step-by-step explanation:

Basically,

The first 2 digits you multiply 8 and 5. Which is 40. Then you add 8 and 5 which is 13. Then subtract 8 and 5 which is 3.

So putting them together you get 40133
