Answer:

x=26

y=116

Step-by-step explanation:

Answer:

Step-by-step explanation:

x8 y5

y=4x+7

First we need to figure out the slope. We can do that using the equation (y2-y1)/(x2-x1). Substitute your numbers in for the xs and ys:

(-9-7)/(-4-0)=

-16/-4=

4

Now that we have the slope, we can figure out the intercept by using the equation y=mx+b and substituting one of the points in for x and y, the slope in for m, and solving for b.

I’m going to use (0,7) as it will be faster:

7=4(0)+b

7=0+b

7=b

The full equation will then be:

y=4x+7

Answer:

picking a prime number

Step-by-step explanation:

from 1 - 20 : 20

>6 : 15

<12 : 11

even number: 10

Prime: (2,3,5,7,11,13,17,19) 8

Answer: 260 minutes.

Step-by-step explanation:

This represents the ratio between the minutes he reads and the pages he reads: 40 : 52

The book Miguel is reading is 338 pages long. Miguel also reads 52 pages in 40 minutes. You can divide 338 by 52, which is equal to 6.5.

If it takes Miguel 40 minutes to read 52 pages, then we can multiply that by 6.5. 40 x 6.5 = 260.

In conclusion, it will take Miguel 260 minutes to read the entire book, or 4 hours and 20 minutes.

Answer:

260 minutes

Step-by-step explanation:

40:52

x:338

338*40=52x

Answer:

Decimal value is 99

Step-by-step explanation:

To convert 01100011 to decimal, we use the zero index method by counting from the last digit

0 = 7

1 = 6

1 = 5

0 = 4

0 = 3

0 = 2

1 = 1

1 = 0

Then we proceed by multiplying the binary digits by 2 and raising them to the power of their zero-index equivalent

(0*2^7) + (1*2^6) + (1*2^5) + (0*2^4) + (0*2^3) + (0*2^2) + (1*2^1) + (1*2^0)

  =(0*128) + (1*64) + (1*32) + (0*16) + (0*8) + (0*4) + (1*2) + (1*1)

      =0 + 64 + 32 + 0 + 0 + 0 + 2 + 1

         = 64 + 32 +3

             =99

Step-by-step explanation:

If D8=127

Therefore D4 =D8 (because corrosponding angles (forming 'F')

Therefore, the D4=D1(because vertically opposite angle)

There fore D4+D1

i. e 127+127 =254

The option (A) is the correct one

Answer:

14x+6

Step-by-step explanation:

Multiply 7x by 2 which gets you 14x and multiply 3 by 2 which is 6.

Explanation:

Think of 6 + y - 3 as 6 + 1y - 3

y and 1y are the same thing because 1 times any number is that same number.

The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:

25

Step-by-step explanation:

In her first 5 days, she reads 80 pages. That means that per day, she reads 16 pages. Then, she had 400 pages left, since 480-80 = 400.

So, you divide 400/16 = 25 days.

x^2-2x-6 +6x - 5

x^2 +4x -11

Answer:

81 miles

Step-by-step explanation:

18x4=72 and then you have to add the 1/2 and 1/2 of 18 is 9 so you add 72+9=81 to get the answer. Hope this helps! <3

Answer:

6967 years

Step-by-step explanation:

Given the exponential function :

R=100e−0.00043t

Time = t in years

R = final amount

Number of years in which only 5 grams of radium will be present :

R = 5

Plugging into our formula :

5 = 100 * e^−0.00043t

5 / 100 = e^−0.00043t

0.05 = e^−0.00043t

Take the In of both sides

−2.995732 = - 0.00043t

t = −2.995732 / - 0.00043t

t = 6966.819

t = 6966.819 years

t = about 6967 years

Answer:

y = -4

x = 3

Step-by-step explanation:

I will be using the elimination method to solve this:

Begin by times -1 to the bottom equation.

[tex]2x-3y=18[/tex]

[tex]-2x-y=-2[/tex]

Add them together

[tex]0x-4y=16[/tex]

ignore the 0x and divide -4 to both sides

[tex]\frac{-4y}{-4} =\frac{16}{-4}[/tex]

y = -4

Plug y back into one of the two original equations

[tex]2x-3(-4)=18[/tex]

multiply -3 and -4 to get +12

[tex]2x+12=18[/tex]

subtract 12 to both sides

[tex]2x=6[/tex]

divide by 2 to both sides

x = 3

Answer:

x intercept: (1,0)

y intercept: (0,3)

Step-by-step explanation: Substitute variables for 0 and solve

Answer:

y-intercept: 3

x-intercept: 1

Step-by-step explanation:

To find x-intercept:

1. make y equal to 0, leaving 9x=9

2. divide both sides by 9

3. x=1

To find y-intercept:

1. make x equal to 0, leaving 3y=9

2. divide both sides by 3

3. y=3

Answer:

an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Step-by-step explanation:

As given ,

f(x) = x³ , g(x) = 9 , h(x) = 2x

Now,

f(2x) = (2x)³ = 2³.x³ = 8x³

⇒f(2x) = 8x³

Now,

[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]

⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]

∴ we get

f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3
