Answer:

x:(-1,0),(5,0)

y:(0,-2)

Answer:

see explanation

Step-by-step explanation:

The x- intercepts are where the graph crosses the x- axis

The graph crosses the x- axis at x = - 1 and x = 5 ← x- intercepts

The y- intercept is where the graph crosses the y- axis

The graph crosses the y- axis at - 2 ← y- intercept

Answer:

$661.25

Step-by-step explanation:

x over 575 times 15 over 100

100=86.25

86.25 is the 15% upcharge

so add 86.25 to the original price

so 575 + 86.25

$661.25

i hope this helps, if you have question let me know! goodluck

plz mark brainliest thanks!

let   −5x+2y=14   be [1]

&        y=3x+2    be [2]  

Finding the value of x

By substituting y in [2] for y in [1]

⇒  −5x + 2(3x+2) = 14         [expand the bracket]

⇒     -5x + 6x + 4 = 14         [subract 4 from both sides and simplify]

⇒                       x = 10

Finding the value of y

Since x =10, we can substitute value of x into [2]

⇒     y = 3(10) + 2

⇒     y = 32

Answer:

[tex]4(6x + 5) = 2x + 10 \\ 4 \times 6x + 4 \times 5 = 2x + 10 \\ 24x + 20 = 2x + 10 \\ 24x - 2x = 10 - 20 \\ 22x = - 10 \\ x = \frac{ - 10}{22} = \frac{ - 5}{11} \\ thank \: you[/tex]

Answer:

-5 / 11 or -0.455

Step-by-step explanation:

this is a very simple question that does not need much complexity about it

we have

4( 6x + 5 ) = 2x + 10

first of all, we open the bracket;

24x + 20 = 2x + 10

now, we have to collect like terms;

24x - 2x = 10 - 20

22x = -10

divide through by 22 to give us!

22x / 22 = -10 / 22

x = -5 / 11

therefore,

x = - 5 / 11

hope that helps

thank you

Answer:

The expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

Step-by-step explanation:

A jellyfish can be up to 1 × 108 times bigger than femtoplankton. Find the size of the largest jellyfish by multiplying the size of a femtoplankton by 1 × 108 times.

The size of a femtoplankton is 2 × 10-8 meter. That means the expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

Answer:

47 1/3 = 142 / 3      total clay

2 1/2 = 5 / 2      clay required for each student

If we divide total clay by clay per student

(142 / 3) / (5 / 2) = 284 / 15 = 18.9

So he should have enough clay for 18 students

Answer:

I think she only needs 1

Step-by-step explanation:

6x6= 36, and since one can needs 36 lucia would only need one

Answer:

1

Step-by-step explanation:

The area of the fence is:

l*b

= 6 * 6

= 36ft^2

The amount that 1 tin of varnish can cover: 36ft^2

Hence, only one tin is required.

Answer:

-1/3 is the slope for this graph

Step-by-step explanation:

-2/6

Answer:

f(-2) = -28

Step-by-step explanation:

f(x) = 12x-4

Let x = -2

f(-2) = 12(-2) -4

Multiply

    = -24-4

Add

  = -28

Answer:

-3

Step-by-step explanation:

The equation to find this is:

[tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]

So, plugging the numbers in:

[tex]\frac{7- 1 }{-2-0 } = -3[/tex]

Answer:

43.2

26.4

6

Step-by-step explanation:

so first if we know that the loger side's ratio is 6 we divided by 7.2

7.2 divided by 6 which is 1.2

so we mulitply the 5 by 1.2

so the shorter side is 6

6 x 7.2 = 43.2 is the area

14.4 + 12 = 26.4 is the perimeter
