How many terms are in the algebraic expression 2x2 - 3y +5?
show work

Answer:

No solution

Step-by-step explanation:

5x−4≥12 AND 12x+5≤−4

solve it separately

5x - 4>=12

add 4 on both sides

5x >= 16

Divide both sides by 5

x > = 16/5

12x+5≤−4

subtract 5 from both sides

12x <= -9

divide both sides by 12

x<= -9/12

x<=-9/12   and x>= 16/5

There is no intersection between the inequalities

so there is no solution

Answer:

a. 53.68

b. 53.53

Step-by-step explanation:

a. Step 1: Approximate the value for [tex]\sqrt{62}[/tex]:

Since [tex]\sqrt{62}[/tex] is close to [tex]\sqrt{64}[/tex] (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.

The expression becomes 6(7.9)+2π

Step 2: Approximate the value for 2π

Since π is approximately 3.14, 2π is approximately 6.28.

The expression becomes 6(7.9)+6.28

Step 3: Use order of operations

6(7.9)+6.28=47.4+6.28=53.68

b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value

[tex]6\sqrt{62} +2\pi =53.5272[/tex]

The approximation 53.68 is decently close to the actual value, so no minor math errors were made.

Answer:

54     and 53.53  see below

Step-by-step explanation:

Estimate the square root first.  7x7 = 49  and 8x8=64 so you can use 8 for your estimate.  You can also estimate Pi as 3.

Now you have:

(6 x 8) + 2(3)   which is 48 + 6 = 54

Using your calculator you get

47.244 + 6.283 = 53.53  rounded to the nearest hundredth

Answer:

38miles/hour

Step-by-step explanation:

Speed = Distance/Time

According to the question:

Time = 0.75hr

Distance = 28.5

Hence,

Speed = 28.5/0.75

= 38 miles/hr

Answer:

Yes it is a linear function

Step-by-step explanation:

Answer:

Answer:

Step-by-step explanation:

gradient = y2-y1/x2-x1

-6/-8

=3/4

It takes 6 hours to reach the destination when traveling at 388 mph.

Speed is the ratio of total distance traveled to the total time taken It is given by:

Speed = distance/time

Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:

582 = distance / 4

distance = 2328 miles

If travelling at 388 mph, the time is:

388 = 2328 / time

time = 6 hours

Hence it takes 6 hours to reach the destination when traveling at 388 mph.

Answer:

[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]

Step-by-step explanation:

A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,

[tex]\sf\implies f(x) = 2x - 8 [/tex]

Let us assume that y = f(x) , so that ,

[tex]\sf\implies y = 2x - 8 [/tex]

Now interchange the positions of x and y , we have ,

[tex]\sf \implies x = 2y - 8[/tex]

Solve for y in terms of x ,

[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]

This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,

[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Answer:

47%

Step-by-step explanation:

.375 × .125 = .046875

rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.

move the decimal three digits to the left and you get, 47%.

Answer:

C, D, E, F

Step-by-step explanation:

Remember y=mxb?

m is slope and b is y-intercept

so y=2/7x-9

Remember that slope is RISE/RUN so for every 2 squares that you go up, you go 7 squares to the right.

Also remember that since your graph is going thru your Cartiesian Plane in quadrent 4, your y value in your ordered pairs will most probably be a negative.

Answer:

9 cups

If x represents the number of cups of dark chocolate needed for 60 candies, the proportion can be ...

 cups/candies = 3/20 = x/60

Multiplying by 60 gives ...

 x = 60(3/20) = 9

You need 9 cups of chocolate for 60 candies.
