Answer:

  a: 0; b: 1; c: 1; d: ∞; e: 0; f: ∞

Step-by-step explanation:

Simplify the expressions to put the left and right in the same form. Then compare. If the x-coefficients are the same, there will be 0 or ∞ solutions. If they are different, there will be 1 solution.

If the x-coefficients are the same, look at the constants. If they are different, there will be 0 solutions. If they are the same, there will be ∞ solutions.

a) -2x -10 = -6x +4x -8  ⇒  -2x -10 = -2x -8 . . . . 0 solutions

b) 0.8x -4.8 = -0.5x +3.4 . . . . 1 solution

c) -1/4x -7/2 = -3x -4 . . . . 1 solution

d) 2x -8 +x = 3x -6 -2  ⇒  3x -8 = 3x -8 . . . . ∞ solutions

e) 3 -2/5x -12/5 = 2 -2/5x  ⇒  -2/5x +3/5 = -2/5x +2 . . . . 0 solutions

f) 6x -6 +21 = 6x +15  ⇒  6x +15 = 6x +15 . . . . ∞ solutions

Answer:

a)3x+7x-8=18

3x+7x=18+8

10x=18+8

10x=26

x=13/5

b)-8+2x=12x-3

-8+2x-12x=-3

2x-12x=-3+8

-10x=-3+8

-10x=5

x=-1/2

e)4/3x-18+2/3x=7/3x+9

4x-54+2x=7x+27

6x-54=7x+27

6x-7x-54=27

6x-7x=27+54

-x=27+54

-x=81

X=-81

d)-2x-4/5 +8/5 =3x-3

-2x-4+8=15x-15

-2x+4=15x-5

-2x-15x+4=-15

-2x-15x=-15-4

-17x=-15-4

-17x=-19

x=19/17

Answer:

B.

Step-by-step explanation:

Irrational as π is irrational.

Answer:

x = 38°

Step-by-step explanation:

this is a four-sided polygon, so the sum of the interior angles measures 360 degrees; formula is (n - 2) · 180 where 'n' is the number of sides

add all four expressions and set equal to 360

5x - 33 + 5x + 13 = 360

10x - 20 = 360

10x = 380

x = 38

check by plugging 38 into each expression to make sure the total is 360

starting in upper left and moving clockwise, the angles are: 75°, 82°, 114°, 89°

Answer:

the required ratio is 7 : 232

Step-by-step explanation:

by solving both sides we get ,

=》7 - ( 7-7 ) : 8 × 29

=》7 - 0 : 232

=》 7 : 232

it's the required ratio ,

i hope you got it .

Answer:

$30

Step-by-step explanation:

Answer:

Sara wants to save 30 dollars.

Step-by-step explanation:

You turn 20% into a decimal which 20%= 0.20

Then you multiply 150 x 0.20 =30

So Sara wants to save $30.

Answer:

x = 12

Step-by-step explanation:

By the alternite intereor angle therom, the two expresions equel each other

8x - 15 = 3x + 45

8x -3x - 15 = 3x - 3x + 45

5x - 15 = 45

5x - 15 + 15 = 45 + 15

5x = 60

5x/5 = 60/5

x = 12

Answer:

8x-15=3x+45 alternate angle

8x-3x=45+15

5x=60

x=60/5=12

Answer:

Step-by-step explanation:

The sum of measures of angles in triangle is allways 180°

So:

   x + 53° + 60° = 180°  {subtract 113° from both sides}

   x = 67°

Answer:

The range of  the function y = 3/4 x + 17 when the domain is -12, -4, 8​ is 8,14,23

Step-by-step explanation:

We need to find the range of the function y = 3/4 x + 17 when the domain is -12, -4, 8​

Basically, we need to find value of y when x is -12,-4 8

The values of y is the range of the given function.

Put x = -12

[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (-12) + 17\\y=3(-3)+17\\y=-9+17\\y=8[/tex]

When x = -12, y= 8

Put x = -4

[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (-4) + 17\\y=3(-1)+17\\y=-3+17\\y=14[/tex]

When x = -4, y = 14

Put x = 8

[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (8) + 17\\y=3(2)+17\\y=6+17\\y=23[/tex]

So, when x = 8, y = 23

The range of  the function y = 3/4 x + 17 when the domain is -12, -4, 8​ is 8,14,23

Answer:

The range of  the function y = 3/4 x + 17 when the domain is -12, -4, 8​ is 8,14,23

Answer:

a = −1 or a = 7

Step-by-step explanation:

Let's solve your equation step-by-step.

( a − 7 ) ( a + 1 ) = 0

Step 1: Simplify both sides of the equation.

a^2 − 6a − 7 = 0

Step 2: Factor left side of equation.

( a + 1 ) ( a − 7 ) = 0

Step 3: Set factors equal to 0.

a + 1 = 0 or a − 7 = 0

a = −1 or a = 7

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

Given

x > - 6

That is if x is greater than - 6 then it is a solution

x ∈ { - 5, - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4, 5, .... } ← are all valid solutions

Thus 5 is a solution to x > - 6
