Answer: Ian is 25 and craig is 20

Step-by-step explanation:

(45 - 5) /2 +5 to one of them

Answer:

Craig is 20 and Ian is 25 years old.

Step-by-step explanation:

I = Ian

C = Craig

I = C + 5

45 = C + I

45 = C + C + 5

45 - 5 = C + C

40 = 2C

C = 20

I = 20 + 5

Craig is 20 and Ian is 25.

[tex] \sf2y + 5z \\ \sf \rightarrow2(9) + 5(2) \\\sf \rightarrow( 2 \times 9) +( 5 \times 2) \\\sf \rightarrow 18 + 10 \\ = \boxed{ \boxed{ \bf28}}[/tex]

Answer:  Opposite Sides are equal and Opposite Sides are parallel

Answer:

C or D since both are the same

Step-by-step explanation:

[tex]x^3+x^2\leq 10x-8\\x^3+x^2-10x+8\leq 0\\(x^2+2x-8)(x-1)\leq 0\\(x+4)(x-2)(x-1)\leq 0[/tex]

So

[tex]x\leq -4 \text{ or } 1\leq x\leq 2[/tex]

The correct solution to the given inequality x³ + x² ≤ 10x – 8 is option D, which is (–ꝏ, –4] U [1, 2].

The given expression is,

x³ + x² ≤ 10x – 8

To solve the inequality,

Start by rearranging the terms to get,

x³ + x² - 10x + 8 ≤ 0.

Then, we can factor the expression to get,

(x-2)(x-1)(x+4) ≤ 0.

From this, we can identify the critical points of the inequality,

Which are x = -4, 1, and 2.

We can then test each interval between the critical points to see whether it satisfies the inequality.

We find that the solution is negative infinity to -4, union 1 to 2,

Which is equivalent to option D.

This solution set includes all the values of x that satisfy the inequality.

Answer:

x = -11

Step-by-step explanation:

2x + 23 + 9 = x + 21

Combine common factors

2x + 32 = x + 21

Subtract x from both sides

x + 32 = 21

Subtract 32 from both sides

x = -11

Step-by-step explanation:

0.96 divide by 12 =0.08

Step-by-step explanation:

multiplied exponents are added.

like x² × x³ = x⁵

so, up there we have

(-2x³y⁴)(-3x⁴y⁴).

as all operations (except for the exponents) are simms multiplications, this results in one longer expression.

(-2)x³y⁴(-3)x⁴y⁴.

we can unite terms of the same base unit.

-2 × -3 = 6

x³x⁴ = x⁷

y⁴y⁴ = y⁸

so, we get

6x⁷y⁸

Answer:

? = 120, ? = 145, respectively

Step-by-step explanation:

? + 60 = 180

? (+ 60 - 60) = 180 - 60

? = 120

35 + ? = 180

(35 - 35) + ? = 180 - 35

? = 145

Answer:

  b = 20/7

Step-by-step explanation:

The slope of the first line can be found by solving for y:

  by = -5x +6 . . . . . . add 6-5x

  y = -5/b +6/b . . . . . divide by b

The slope is -5/b.

The slope of the second line can be found by solving for y:

  7y = 4x +7

  y = 4/7x +1 . . . . . . divide by 7

The slope is 4/7.

For the lines to be perpendicular, the product of these slopes must be -1:

  (-5/b)(4/7) = -1

  -20/(7b) = -1 . . . . simplify

  b = 20/7 . . . . . . . multiply by -b

The lines will be perpendicular when b = 20/7.
