Evaluate the expression for the given values of the variables.

(n + 5)2 for n = −7

When n = −7, the expression is equal to...

Answer:

A. (3 , 1)

Step-by-step explanation:

Note the placement of x and y for points:

(x , y)

Plug in the corresponding numbers for the corresponding variables:

(x , y) = (3 , 1)

y = x - 2

(1) = (3) - 2

1 = 3 - 2

1 = 1 (True).

A. (3 , 1) is your answer.

Answer: 60 quarters and 40 dimes

Step-by-step explanation:

Step 1: Setup Coin Value and Coin Total Equation:

Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters

Coin Total Equation → d + q = 100

Step 2: Rearrange Coin Total Equation in terms of dimes (d)

d = 100 - q  ← Revised Coin Total Equation

Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:

0.1(100 - q) + 0.25q = $19.00

0.1(100) - 0.1(q) + 0.25q = $19.00

10 - 0.1q + 0.25q = $19.00

10 + (0.25 - 0.1)q = $19.00

10 + 0.15q = $19.00

Step 4: Subtract 10 from each side of the equation to isolate q

10 - 10 + 0.15q = $19.00 - 10

0.15q = 9

Step 5: Divide each side of the equation by 0.15 to isolate q

0.15q/0.15  =    9/0.15

q = 60

Step 6: Using our value for q, Solve for d using our Coin Total Equation:

d + 60 = 100

Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60

d = 40

Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

Answer:

4x+9=x+15

x = 2

Step-by-step explanation:

Let's solve this equation I just made:

4x + 9 = x + 15

Subtract 9 from each side:

4x = x + 6

Subtract x from each side:

3x = 6

Divide each side by 3:

x = 2

the reciprocal is 8/-9 just reverse the numbers

The slope of the line is m = -3

The y-intercept is (0,5)

The equation of the line in the slope-intercept form is y = 5-3x

Answer:

12

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]

She needs 12 more sessions.

Answer:

I put 4, 5, & 6 in order in the photos.

7-8-9 are all linear functions which are written in the y=ax+b format, the ones I put in bold are the equations and I listed the values just in case I'm not sure how your teacher makes you write them.

7.

-0.6=a(-3)+b

0.2=a(1)+b

1.4=a(7)+b

a=0.2,b=0

y=0.2x

8.

-10=a(-5)+b

-1=a(-2)+b

17=a(4)+b

b=5, a=3

y=3x+5

9.

8=a(-5)+b

2=a(-2)+b

-18=a(8)+b

b=-2, a=-2

y=-2x-2

The domain and range is negative infinity to infinity.

For a basic subscription, a cable television provider charges an activation fee of $60, plus $125 per month. What linear function represents the total cost of basic cable subscription for t months? What is the total cost for two years of service?

y=125x+60

$310 for 2 months

$3060 for 2 years

Step-by-step explanation:  let x be the number of months

y=125x+60

y=125(2)+60

y=310 dollars for two months

y=125(24)+60

y=3060 dollars for two years

I hope it helps!

Please post the question dear!

Answer:

how can I help u plz can u say

Answer:

steps below

Step-by-step explanation:

1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator       (-3a) / 2 = 5 / 4

-12a = 10

a = - 5/6

2) 3-n > n+ 10  ... degree of the denominator < degree of the numerator

   2n < -7

   n < - 3.5

The largest inter value is -4

3) f(x) = (x²+3x-4) / (2x²+7x-10)

   f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2

   x->∞ : divide x² both numerator and denominator, any number/ x -> 0

   f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2

   [tex]\lim_{x \to \infty} f(x) = f(2)[/tex] = 1/2

Answer:

50°

Step-by-step explanation:

According to the vertical angle theorem, two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

This would mean CBD is equal to ABE which means ABE would be 50°.

Answer:

6  pencils

Step-by-step explanation:

Total cost = paper * cost of a package + pencils * cost of a pencils

We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars

15  = 1*3 + p*2

15 = 3+2p

Subtract 3 from each side

15-3 = 3+2p-3

12 = 2p

Divide by 2

12/2 = 2p/2

6 = p

Answer:

b = -20

Step-by-step explanation:

b + 2 = -18

b = -20

Answer:

b= -20

Step-by-step explanation:

the first step is to subtract 2 from both sides of the equation.

b + 2 = -18

   -2      -2

-------------------

the -2 and +2 cancel

b = -20
