Answer:

x = - 10

Step-by-step explanation:

5(x + 8) = - 10

5x + 40 = - 10

5x + 40 - 40 = - 10 - 40

5x = - 50

5x ÷ 5 = - 50 ÷ 5

x = - 10

Answer:

Step-by-step explanation:

sin^-1(7/16)= 25.9 degrees

Step-by-step explanation:

x=10

y=24

r=√10²+24²=√100+576=√676=26

sin = y/r = 24/26

cos = x/r =10/26

tan=y/x = 24/10

csc = r/y=26/24

sec= r/x = 26/10

tan = x/y = 10/24

Answer:

e = 10

Step-by-step explanation:

14e + 4 - 14 - 13e = 0

e + 4 - 14 = 0

e - 10 = 0

e = 10

HOPE THIS HELPS

Answer:

e = 10

Step-by-step explanation:

9e + 4 = 8e + 14

1) add -8e at the two members

9e +4 -8e = 8e -8e + 14

e +4 = 14

2) add -4 at the two members

e+4 -4 = 14 - 4

e = 10

Answer:

It would be the orange popsicle sticks

Step-by-step explanation:

The color Orange has a 1/5 chance of being chosen.

Find the total: 4 + 8 + 3 = 15

Yellow = 4

[tex]\frac{4}{15}[/tex]

[tex]\frac{4}{15}[/tex], cannot be reduced any further so we know the color yellow is not the correct answer.

Purple = 8

[tex]\frac{8}{15}[/tex]

[tex]\frac{8}{15}[/tex], cannot be reduced any further so we know the color yellow is not the correct answer.

Orange = 3

[tex]\frac{3}{15}[/tex] simplifies into [tex]\frac{1}{5}[/tex]

So Orange is the correct answer.

Answer:

Once.  The point of intersection is (-5/7, 3)

Step-by-step explanation:

Once.  You have two straight lines here with different slopes, and neither is the negative reciprocal of the other.  There is one solution to this system of linear equations.

Setting the two equations equal to each other, we get

y = -4 + 1 = 7x + 2, or

-3 = 7x + 2, or

7x = -5, or x = -5/7.  

From the first equation and x = -5/7, we find y:

y = 7(-5/7) + 2, or y = -5 + 2, or y = 3.

The ONE solution is (-5/7, 3)

'Function' is described as 'a relation in which each component of the domain is related to precisely one component of the codomain.'

B). The statement second "Limit of f(x) = - 2 as x approaches 1 minus. Limit of f(x) DNE as x approaches 1+" correctly elaborates the single-sided limits when the end-point dislocates.

Thus, option B is the correct answer.

Answer:

point of intersection are

(-2,0) and (0,1)

we have

equation of a line is :

(x-x1)=(y2-y1)(/(x2-x1)*(y-y1)

(x+2)=(1-0)/(0+2)*(y-0)

x+2=½y

y=2x+4 is a required equation in a slope intercept form.

Answer:

(8x4 + 7x3 - 9) – (5x2 - 8x + 6)

Answer:

x = -7

Step-by-step explanation:

-3x -5 = 16

step 1 add 5 to each side

-5 + 5 cancels out

16 + 5 = 21

we now have -3x = 21

step 2 divide both sides by -3

-3x / -3 = x

21 / - 3 = -7

we're left with x = -7

Answer:

x = -7

Step-by-step explanation:

-3x -5 = 16

     +5   +5

-3x = 21

-3x/-3 = 21/-3

x = -7

Step-by-step explanation:

function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. for ex. if x include 1,2,3 and y include 0,9.8 we aaythere is a relation between x and y that make 1 from x equal with 0 from 7 or 3 from x equals with 8 from 6.

Given:

A quadrilateral inscribed in a circle.

To find:

The value of x and y.

Solution:

If a quadrilateral inscribed in a circle, then it is known as cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles, it means their sum is 180 degrees.

[tex]5x^\circ+110^\circ=180^\circ[/tex]                     [Supplementary angles]

[tex]5x^\circ=180^\circ -110^\circ[/tex]

[tex]x^\circ=\dfrac{70^\circ}{5}[/tex]

[tex]x^\circ=14^\circ[/tex]

The value of x is 14 degrees.

[tex]2y^\circ+104^\circ=180^\circ[/tex]                     [Supplementary angles]

[tex]2y^\circ=180^\circ -104^\circ[/tex]

[tex]y^\circ=\dfrac{76^\circ}{2}[/tex]

[tex]y^\circ=38^\circ[/tex]

Therefore, the value of x is 14 degrees and the value of y is 38 degrees.

Answer: A

O The median-median regression line is a better prediction.

Step-by-step explanation:

The given median-median line for a dataset is

y 1.133x+ 0.489

The least-squares regression line for the same dataset is

y = 1.068x0.731

The given point is (50,60).

Substitute x=50 in each given equation.

y = 1.133(50) + 0.489

57.139

y = 1.068(50) + 0.731 = 54.131

Since the value of median-median line at x=50 is near to 60 than the value of least-squares regression at x=50.

The median-median line regression line is a better prediction. Therefore the correct option is A.

Answer:

1

Step-by-step explanation:

Step 1: 2 plus 2

=> 2 + 2

=> 4

Step 2: times 0

=> 4 * 0

=> 0

Step 3: divided by 4

=> 0/4

=> 0

Step 4: time 99

=> 0 * 99

=> 0

Step 5: plus 1

=> 0 + 1

=> 1

Therefore the final answer = 1
