Step-by-step explanation:

x/7=4

x = 7 × 4

x = 28

......

Answer:

=14

Step-by-step explanation:

1/x=1/7+4root x7-4 root

7-4root3=7²-1(4root)²=7-4root3

49-48

then

1/2=7-4root 3

x+ 1/x=7x4 cross out root 3+7-4

=7+7=14

Answer:

The explicit function is: [tex]P_x = 153+3x[/tex]

And the number of lights after 33 weeks will be 252.

Step-by-step explanation:

Given that:

Total street lights = 153

Let x be the number of weeks

Then the number lights after x weeks will be 3x

This is a linear function where the y-intercept is 153 and slope is 3.

It can be written as: y = mx+b

The function is:

[tex]P_x = 153+3x[/tex]

Putting the values for x will give us the number of total lights after that number of weeks.

To find, how many street lights were there at the end of 33rd week,

Putting x = 33

[tex]P_{33} = 153+ 3(33)\\= 153+99 = 252[/tex]

Hence.

The explicit function is: [tex]P_x = 153+3x[/tex]

And the number of lights after 33 weeks will be 252.

Answer:

They have to drive 2,050,650 more miles. Which is also 0.4 of the whole road trip.

Step-by-step explanation:

Subtract the miles they have already driven from the miles of the entire trip. Then use that and divide it by the miles of the entire trip and you'll get 0.4.

There are a couple of ways to do this. The easiest is to take the number of degrees between 42 and - 54 and divide by 12.

Method

the number of degrees is abs(42) + abs(-54) = 42 + 54 = 96

Now divide by 12

Hours = 96 / 12 = 8 hours.

Answer:

gof(x) = 3

Step-by-step explanation:

Given that,

f(x) = x+2 and g(x) = x+1

We need to find gof(x).

gof(x) means g[f(x)].

g[f(x)] = g(x +2)

= x+2+1

= x+3

Hence, the value of gof(x) is 3.

Answer:

$2492.1

Step-by-step explanation:

Step one

Given

Principal=$2130

rate= 4.25%= 0.0425

time = 4 years

Required:

The final amount in the account

Step two:

the expression for the final amount is

A= P(1+rt)

substitute

[tex]A=2130(1+0.0425*4)\\\\A=2130(1+0.17)\\\\A=2130*1.17\\\\A=2492.1[/tex]

Answer:

a = 31

Answer:

x = - 23.57 (appx)

Step-by-step explanation:

[tex]( \frac{ - 7}{3} )x - 3 = 52[/tex]

[tex] = > ( \frac{ - 7}{3} )x = 52 + 3 = 55[/tex]

[tex] = > x = 55 \div ( \frac{ - 7}{3} )[/tex]

[tex] = > x = \frac{55 \times 3}{ - 7} = \frac{165}{ - 7} = - 23.57(appx)[/tex]

Answer:

(-7,-16)

Step-by-step explanation:

calculate the first derivative and equale tot zero.

dy/dx = 2x + 14 = 0

<=> x = -7

calculate now the value of y for x = -7

y = (-7)^2 + 14*(-7) + 33

y = 49 - 98 + 33

y = -16

Answer:

the function is -3 i think

Answer:

[tex]f(x) = x - 3[/tex]

Step-by-step explanation:

Linear equation form:

[tex]y=mx+b[/tex]

m is the slope

b is the y intercept

Solve for m using the first two points:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{6-7}{3-4}[/tex]

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

[tex]m=1[/tex]

Plug in m and either point into the equation and solve for b:

[tex]y=mx+b[/tex]

[tex]4=1(7)+b[/tex]

[tex]4=7+b[/tex]

[tex]b=4-7[/tex]

[tex]b=-3[/tex]

Final equation:

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

Test with the 3rd point:

[tex]2=5-3[/tex]

[tex]2=2[/tex]

Equation fits all 3 points

Answer:x^2-y^2

Step-by-step explanation:

(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2

Answer:

$149.27

Step-by-step explanation:

Find the tip first, so:

126.5 · 18/100 = 2277/100 = 22.77

Now that we found the tip, just add that with the bill:

$126.50 + $22.77 = $149.27

Answer:

C

Step-by-step explanation:

y=-3x+5

Let's try A: 14=-3*3+5=-9+5=-4 (NOT TRUE)

Let's try B: 17=-3*4+5=-12+5=-7 (ALSO NOT TRUE)

Let's try C: 17=-3*(-4)+5=12+5=17 (TRUE)

Let's try D: 23=-3*6+5=-18+5=-13 (NOT TRUE)

Answer:

130

Step-by-step explanation:

So there's only only 2 candidates, 35% of the students voted for Leandro that means that 65% of the students voted for Gerardo as 100% - 35% = 65%

70 is 35% of the students, therefore we need to find a factor where we can multiply 35% to be 100%, so we can multiply it with 70 as well, to find all the students. 100 divided by 35 is 2.85714285714. Now we have to multiply 70 with that number. 70 times 2.85714285714 is 200.

Okay so 70 students voted for Leandro, and there are 200 students in total. So now we subtract to find how many voted for Gerardo. 200 - 70 = 130

130 students voted for Gerardo
