Answer:

-8x

Step-by-step explanation:

Multiply -8 and x so it is -8x

Answer:

Does fill in!!!!

Step-by-step explanation:

1st substitute x with -4

5+3(-4)=-7

2nd step multiply

5-12=-7

3rd step subtract

-7=-7

so yes -4 is correct!!!!

Answer:

-4 is a solution

Step-by-step explanation:

x = -4

Equation:

5 + 3x = -7

Substitute x for -4

New equation:

5 + 3 x -4 = -7

Solve:

3 x -4 = -12

5 + -12 = -7

-7 = -7

Answer:

The missing angle is 40 degrees

Step-by-step explanation:

Tan = opposite / adjacent

Tan ? = 24 / 29

24 / 29 = 0.8275

Tan-1 of 0.8275 is 39.610

Round to the nearest degree

39.610 = 40

Answer:

Step-by-step explanation:

Here you have a right triangle with the side lengths 24 and 29 and are asked to find the measure of the smallest angle.

In cases like this you should ask yourself which trig function includes the lengths of the legs (that is, the lengths of the side opposite the angle and the side adjacent to the angle).  That would be the tangent function, and so:

tan (?) = (opposite side) / (adjacent side)

Here, tan x = 24/29 = 0.691.  Note:  I used my TI-83Plus calculator to determine that the measure of angle x in radians is 0.691.

The unknown angle is 0.691 radians, or (multiplying that by the conversion factor (180/pi) ) 39.6 degrees.  To the nearest degree, that'd be 40 degrees.

Given:

f(x) is an exponential function.

[tex]f(-3.5)=25, f(6)=33[/tex]

To find:

The value of f(6.5).

Solution:

Let the exponential function is

[tex]f(x)=ab^x[/tex]         ...(i)

Where, a is the initial value and b is the growth factor.

We have, [tex]f(-3.5)=25[/tex]. So, put x=-3.5 and f(x)=25 in (i).

[tex]25=ab^{-3.5}[/tex]         ...(ii)

We have, [tex]f(6)=33[/tex]. So, put x=6 and f(x)=33 in (i).

[tex]33=ab^{6}[/tex]         ...(iii)

On dividing (iii) by (ii), we get

[tex]\dfrac{33}{25}=\dfrac{ab^{6}}{ab^{-3.5}}[/tex]

[tex]1.32=b^{9.5}[/tex]

[tex](1.32)^{\frac{1}{9.5}}=b[/tex]

[tex]1.0296556=b[/tex]

[tex]b\approx 1.03[/tex]

Putting b=1.03 in (iii), we get

[tex]33=a(1.03)^{6}[/tex]

[tex]33=a(1.194)[/tex]

[tex]\dfrac{33}{1.194}=a[/tex]

[tex]a\approx 27.63[/tex]

Putting a=27.63 and b=1.03 in (i), we get

[tex]f(x)=27.63(1.03)^x[/tex]

Therefore, the required exponential function is [tex]f(x)=27.63(1.03)^x[/tex].

Step-by-step explanation:

i hope that helps!

Answer:

1  1/9

Step-by-step explanation:

10/9, you get 1 as the whole number.

You have a 1 left over when dividing 10 and 9. the 1 will be over 9.

Giving you 1 as the whole number and 1/9 next to it.

Answer:

The expression is:

y=500x+550p, where

y is the amount earned

x is the quantity of Xboxes sold

p is the amount of Playstations sold

Step-by-step explanation:

With the information provided, you can say that the amount of money they will earn for selling Playstations and Xboxes is equal to the sum of the result of multiplying the price per Xbox Series X for the quantity sold plus the result of multiplying the price per Playstation 5 for the quantity sold, which can be expressed as:

y=500x+550p, where

y is the amount earned

x is the quantity of Xboxes sold

p is the amount of Playstations sold

Answer:

x

Answer:

y+3=-11/7(x-2)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-(-3))/(-5-2)

m=(8+3)/-7

m=11/-7

y-y1=m(x-x1)

y-(-3)=-11/7(x-2)

y+3=-11/7(x-2)

Answer:

1) 60 miles

2) 7 dollars

Step-by-step explanation:

1) Question 1

Let x be equal to the full distance of the trip

[tex]0.4x=24[/tex]

Divide both sides by 0.4

[tex]\frac{0.4x}{0.4}=\frac{24}{0.4} \\x=60[/tex]

Therefore, the trip is 60 miles long.

2) Question 2

Let y be equal to the price that Marco paid for the doll.

[tex]35*0.2=y[/tex]

We multiply 35 by 1-0.8 because the doll is 80% off, meaning he's paying for 20% of the original price

[tex]7=y[/tex]

Therefore, Marco paid $7 for the doll.

Answer: 2/3 hours

Step-by-step explanation:

okay so the speed now is 850, which is   850/340  = 2.5 times the original speed

Since It's 2.5 times the original speed,

2.5x = 5/3

so x = 5/3/2.5 = 2/3

Answer:

2/3 of an hour

Step-by-step explanation:

Here is the information that the question gives us.

A plane covers a distance in 5/3 of an hour at 340 km per hour. How long would it take for a plane to cover the same distance while traveling at 850 km per hour?

Remember, distance = speed * time. Using that formula, we can find the distance with this equation:

distance = 340 * 5/3

Multiply.

distance = 1700/3 km

Then, we can plug this distance in to find the time it would take for a plane going at 850 km/hour.

distance = speed * time

1700/3 = 850 * time

Divide both sides by 850

(1700/850) / 3 = time

time = 2/3 hour

Thus, the answer is 2/3 of an hour.

Just in case, let's check the answer. Because both the planes travel the same distance, then their speeds * time should both equal "distance". In other words, they should be equal.

340 * 5/3 = 2/3 * 850

Simplify.

1700/3 = 1700/3

So, the answer is correct.

I hope this helps! Feel free to ask any questions!
