Answer:

x = - (15 - 11y)/4

y = x/2

Step by step explanation:Let's first solve for x

=>- 4x + 11y = 15

=>- 4x + 11y - 11y = 15 - 11y

=>- 4x = 15 - 11y

=>(- 4x)/- 4 = 15/- 4 - (11y)/- 4

x = - (15 - 11y)/4

let's solve for y

=>x = 2y

=>2y = x

=>(2y)/2 = x/2

y = x/2

Step-by-step explanation:

I used a calculator, pls let me know if im incorrect

The degrees on a triangle add up to 180.

(x) + (x-7) + (3x+12) = 180 ; Just shwoing what i'm doing.

x + x-7 + 3x + 12 = 180

5x + 5 = 180 ; x + x + 3x = 5x , 12 - 7 = 5

5x = 175 ; Subtract 5 from 180

x = 35 ; 175/5 = 35

P: x - 7 = 35 - 7 = 28

Q: 3 (x) + 12 = 3 (35) + 12 = 105 + 12 = 117

R: x = 35

Answer:

The remainder is 40.

Step-by-step explanation:

We're applying synthetic division here.

The coefficients of this function are {1, 6, -3, 0}.  The divisor (x + 5) is represented by the monomial divisor -5.

Setting up synthetic division, we get:

-5    1    6    -3    0

            -5   -5   40

      ---------------------

       1     1    -8    40

The remainder is 40.

Answer:

72+(7x+24)=180

7x+96=180

7x=84

x=12

Step-by-step explanation:

Answer: x = 12.

Step-by-step explanation:

72 + (7x + 24) = 180   Now we add like terms

96 + 7x = 180             Take away 96 from both sides

7x = 84                       Divide both sides by 7

x = 12                          X equals 12.

Answer:

(a) [tex]x=-2,3[/tex] (b) [tex]x=\frac{3}{4} ,-\frac{11}{4}[/tex]

Step-by-step explanation:

[tex]y=x^2-x-6\\y=2x^2+x-6[/tex]

For the first equation, this can easily be factored

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

Now, set each of their factors equal to zero and solve

[tex]x+2=0\\x=-2\\\\x-3=0\\x=3[/tex]

Therefore, for a, the roots of [tex]y=x^2-x-6[/tex] are [tex]x=-2, 3[/tex]

For the second equation, it is able to be factored, however, its normally easier to use the quadratic equation to solve polynomials with an a term greater than 1

[tex]y=2x^2+x-6[/tex]

[tex]x_{1} =-b+\frac{\sqrt{b^2-4ac} }{2a}=-1+\frac{\sqrt{1-4(2)(-6)} }{4}=-1+\frac{\sqrt{1-(-48)} }{4}=-1+\frac{\sqrt{49} }{4} =-1+\frac{7}{4}=\frac{3}{4}[/tex]

[tex]x_{2}=-b-\frac{\sqrt{b^2-4ac}}{2a}=-1-\frac{\sqrt{1-4(2)(-6)} }{4} =-1-\frac{\sqrt{1-(-48)} }{4}=-1-\frac{\sqrt{49} }{4}=-1-\frac{7}{4} =-\frac{11}{4}[/tex]

Hope this helps! :)

Answer:

10

Step-by-step explanation:

1. The formula to find the slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. All we have to do is plug in the values and simplify.

2. (Solving)

Therefore, the slope is 10.

Step-by-step explanation:

Ive heard this joke before lol so corny

1. If two parallel lines are cut by a transversal then the pair of consecutive interior angles are supplementary.

2. If two parallel lines are cut by a transversal then pair of alternate interior angles are equal.

3. m∠1 is  106°.

4.  m∠3 is 74°

5.  m∠8 is 114°

6.  m∠6 is  124°

7. m∠7 is  66°

8.  m∠2 is 66°

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

1. If two parallel lines are cut by a transversal then the pair of consecutive interior angles are supplementary.

2. If two parallel lines are cut by a transversal then pair of alternate interior angles are equal.

3. m∠2 is 74° then m∠1 is (180 - 74)° = 106°.    (linear pair of angles)

4. m∠2 is 74° then m∠3 is 74°.    (vertically opposite angles)

5. m∠1 is 114° then m∠8 is 114°   (alternate angles)

6. m∠4 is 56° then m∠6 is (180 - 56)° = 124°  (180° - m∠5)

7. m∠1 is 84° then m∠7 is (180° - m∠8) = 180° - 114° = 66°.

8. m∠8 is 114° then m∠2 is m∠7 = 66°

Answer:

domain: (–∞,∞)    or  all real numbers

range: (–∞,∞)       or  all real numbers

Step-by-step explanation:

domain is left to right (x-axis). looking at the graph, as you go from left to right, the x-values are infinitely getting more negative and positive.

range is bottom to top (y-axis). as you go from bottom to top, the y-values are infinitely getting more negative and positive.

y2−x2+1=50

Step 1: Add -y^2 to both sides.

−x2+y2+1+−y2=50+−y2

−x2+1=−y2+50

Step 2: Add -1 to both sides.

−x2+1+−1=−y2+50+−1

−x2=−y2+49

Step 3: Divide both sides by -1.

−x2

x2=y2−49

Step 4: Take square root.

x=√y2−49 or x=−√y2−49

Answer:

x=√y2−49 or x=−√y2−49

y2+6y+9=x+8

Step 1: Flip the equation.

x+8=y2+6y+9

Answer:

58

Step-by-step explanation:

We are given the arithmetic sequence:-

-12,-7,-2,3,...

First, find the common difference which we can obtain by:-

[tex] \displaystyle \large{d = a_{n + 1} - a_n}[/tex]

Check:-

-7-(-12) = -7+12 = 5

-2+7 = 5

3+2 = 5

Therefore, our common difference is 5.

General Arithmetic Term

[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]

Since we want to find the 15th term, substitute a1 = -12, n = 15 and d = 5.

[tex] \displaystyle \large{a_{15}= - 12 + (15 - 1)5} \\ \displaystyle \large{a_{15}= - 12 + (14)5} \\ \displaystyle \large{a_{15}= - 12 + 70} \\ \displaystyle \large{a_{15}= 58} \\ [/tex]

[tex] \sqrt{12} \\ = \sqrt{4 \times 3} \\ = \sqrt{2 \times 2 \times 3} \\ = 2 \sqrt{3} [/tex]

The answer is 2√3.

[tex] \sqrt{12} \\ = \sqrt{2 \times 2 \times 3} \\ = \boxed{ 2 \sqrt{3} }[/tex]

Answer:

3.4156020*10^-1 for scientific notation if you want to keep that ending zero (I'd normally write it 3.415602*10^-1)

Step-by-step explanation:

So the idea of scientific notation (or engineering notation) is to make things smaller and more manageable. The idea is to move the variables so that one is in front of the point.

So if you had something like this:

12342300000000000000

It'd be equal to 1.23423*10^19

Or something like this

0.0000095675

Would be 9.5675*10^-6

Angle 8 and Angle 2 are supplementary. So Angle 8 + 70 would equal to 180.

180-70 is 110 hence angle is 110 degrees.
