Answer:

(-4,-5) (-3,-3)

Step-by-step explanation:

[tex](-4,-5),(-3,-3)[/tex]

Given equation is [tex]y=2x+3[/tex]

Put [tex](x,y)=(-4,-5)[/tex]

[tex]-5=2(-4)+3\\-5=-5[/tex]

Put [tex](x,y)=(-3,-3)[/tex]

[tex]-3=2(-3)+3\\-3=-3[/tex]

Put [tex](x,y)=(-1,0)[/tex]

[tex]0=2(-1)+3\\0\neq 1[/tex]

Put [tex](x,y)=(-1,-4)[/tex]

[tex]-4=2(-1)+3\\-4\neq 1[/tex]

So, [tex]\boldsymbol{(-4,-5),(-3,-3)}[/tex] lie on the graph [tex]y=2x+3[/tex]

Answer:

there is no graph.

Step-by-step explanation:

A decrease in the ratio 4:5 implies that :

New quantity:Old quantity = 4:5

Let the new quantity be [tex] \bf \: x[/tex]

[tex] \bf∴ x : 40 = 4:5[/tex]

[tex] = > \bf \frac{x}{40} = \frac{4}{5} [/tex]

[tex] \bf = > 40 \times \frac{x}{40} = 40 \times \frac{4}{5} [/tex]

[tex] \bf = > x = 8 \times 4[/tex]

[tex] \bf = > x = 32[/tex]

So, the new quantity is 32

Answer:

1,5,9,13,17,21,25,29

Step-by-step explanation:

From the information given.

Let represent the number of white beads with x and the number of blue beads with y. So, the beads can be illustrated as:

bead   color

1             x

2            y

3            y

4            y

5            x

6            y

7            y

8            y

Suppose n denotes the no. of beads that are white.

Then the subsequent no is ( n + 4).

Since the first number n = 1

Then the subsequent numbers will follow the pattern of adding 4 to the number.

i.e.

n = 1 + 4 = 5

n = 5 + 4 = 9

n = 9 + 4 = 13

n = 13 + 4 =1 7

n = 17 + 4 = 21

n = 21 + 4 = 25

n = 25 + 4 = 29

Thus, the number for the first eight beads that are white are:

1,5,9,13,17,21,25,29

The pattern shows odd numbers only.

Answer:

[tex]\sqrt{12}[/tex] units

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the other leg, then

x² + 2² = 4²

x² + 4 = 16 ( subtract 4 from both sides )

x² = 12 ( take the square root of both sides )

x = [tex]\sqrt{12}[/tex] units

which can be simplified to 2[tex]\sqrt{3}[/tex] units , if required.

Answer and Step-by-step explanation:

Step-by-step explanation:

y - 8 = -8(x + 2)

y - 8 = -8x - 16

y = -8x - 8

The slope-intercept form is y = -8x - 8.

Answer:

y = -8x - 8

Step-by-step explanation:

First distribute the -8 into the parentheses

next get the the y by itself

add 8 to both sides and you get

y = -8x - 8

Answer:

[tex]6[/tex], [tex]8[/tex] and [tex]10[/tex]

Step-by-step explanation:

Let [tex]x =[/tex] smallest consecutive even integer.

Since the second and third consecutive even integers can be expressed by our smallest even consecutive integer, we can express them as:

Second consecutive even integer = [tex]x+2[/tex]

Third consecutive even integer = [tex]x+4[/tex]

From "the sum of the second and third is 3 times the first integer", we can write:

[tex]x+2+x+4 = 3x[/tex]

[tex]2x+6 = 3x[/tex] (collect like-terms)

[tex]x=6[/tex]

∴ The first consecutive even integer is 6

Now, we can use substitution to find the values of the second and third consecutive even integers:

Second consecutive integer = [tex]x+2[/tex]

[tex]=6+2[/tex]

[tex]=8[/tex]

Third consecutive integer = [tex]x+4[/tex]

[tex]=6+4[/tex]

[tex]=10[/tex]

∴ The three consecutive even integers are [tex]6[/tex], [tex]8[/tex] and [tex]10[/tex].

Given :

An equation 2cot x = -3sec x .

To Find :

the values of x in [0, 360°) which satisfy the given equation.

Solution :

Converting cot x and sec x in the form of sin x and cos x.

[tex]\dfrac{2cos \ x}{sin\ x}= \dfrac{-3}{cosx}\\\\2cos^2 x +3 sin\ x =0\\\\2( 1 - sin^2 x ) + 3sin \ x = 0 \\\\2sin^2 x -3sin\ x -2 = 0\\\\2sin^2\x -4sin\ x + sin\ x -2 = 0\\\\2sin\ x( sin\ x - 2 )+ 1( sin \ x - 2 ) = 0\\\\sin \ x = \dfrac{-1}{2} \ or\ sin \ x = 2[/tex]

Neglecting sin x = 2 because sin x cannot be greater than 1.

x = π - π/6, π + π/6

x = 5π/6 and x = 7π /6

Therefore, the values of x in [0,360°) is  5π/6 and x = 7π /6 .

Answer:

t ≤ 2

Step-by-step explanation:

Given that:

Initial Position = - 26 feets (below surface)

Descent rate = 26 feets per minute

Maximum depth = 78 feets

Let t = number of minutes

Hence,

Initial position + (descent rate * number of minutes) ≤ - 78

-26 + (- 26t) ≤ - 78

-26t ≤ - 78 + 26

-26t ≤ - 52

t ≤ 52/26

t ≤ 2
