Identify the slope and the y-intercept of the following line!
y=-3+x

Answer

n = 30

Explanation

To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.

You 'remove' these numbers in backward PEMDAS.

So to 'remove' the 18, you subtract both sides by 18.

3-18 = -15

-n/2+18-18 = -n/2

So now you are left with -15 = -n/2.

To 'get rid' of the 2, you multiply each side by 2.

-15×2 = -30

-n/2×2 = -n

And now you have -30 = -n.

To 'get rid' of the negative sign, you multiply both sides by -1.

-30×-1 = 30

-n×-1 = n

So you get 30 = n or n = 30.

Answer:

The answer is C:$87.50

Step-by-step explanation:

Ben - 1$

David - 0.75$

For each Bagel, Ben paid 0.25$ extra.

Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$

Then david spent = 3/4*50 = 37.5$

Total = 50+37.5 =$87.50

Answer:

Step-by-step explanation:

Explanation: There is nothing known as opposite in algebra. If you mean additive inverse it is 34 and if you mean multiplicative inverse or reciprocal it is −43 . multiplicative inverse, also called reciprocal, is the number which when multiplied with the number results in 1 , the multiplicative identity element.

Answer:

The opposite of 3/4 would be 4/3, simplified would be 1 1/3.

Answer:

The measure of the third angle must be 104°

Step-by-step explanation:

Interior Angles of a Triangle

In any given triangle, the sum of its interior angles is 180°.

We are given the angles x=51° and y=25°. To find the third angle, z, we set up the equation:

x + y + z = 180

Solving for z:

z = 180 - x - y

Substituting:

z = 180 - 51 - 25

z = 104°

The measure of the third angle must be 104°

Answer:

[tex]Blue = 4.8 \ Gallons[/tex]

Step-by-step explanation:

Given

[tex]Y : B = 3 ; 2[/tex]

Required

Find the  number of blue paints in 12 gallons

Start by representing the blue part of the ratio as a fraction

[tex]Y : B = 3 ; 2[/tex]

[tex]B = \frac{2}{2 + 3}[/tex]

[tex]B = \frac{2}{5}[/tex]

This means that:

[tex]Blue = \frac{2}{5} * 12\ Gallons[/tex]

[tex]Blue = \frac{24}{5} \ Gallons[/tex]

[tex]Blue = 4.8 \ Gallons[/tex]

Answer:

function: x=-4

y-intercept: f(0)=-37

Step-by-step explanation:

hope this helps!

The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:

f(x) = -2x² - 16x - 37.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To rename the quadratic function f(x) = -2(x + 4)^2 - 5 in standard form, we need to expand and simplify the expression:

f(x) = -2(x + 4)² - 5

f(x) = -2(x² + 8x + 16) - 5

f(x) = -2x² - 16x - 32 - 5

f(x) = -2x² - 16x - 37

Therefore,

The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:

f(x) = -2x² - 16x - 37.

Answer:

348 feet

Step-by-step explanation:

Answer:

-348

or 348 feet under the oceans surface

Step-by-step explanation:

since your already 100 feet below the surface, if you go down(descends) another 248 feet. You subtract 248 from -100, you get -348.

So your 348 feet below sea level.

Answer: x = 2

Step-by-step explanation:

The rule for reflecting over  x = 2 is that y remains the same and you add how many units x = 2 is from the point.

x = 2 is has the coordinate of x = 2 and y = the y coordinate of the point.

A (-1, 1) Since the y coordinate of (-1, 1) is 1, x = 2 - (2, 1)

Add 3 units to 2, the x coordinate since -1, 1 is 3 units from 2, 1

2,1 --> 5, 1

The steps are given.

To find:

The mistake in her steps.

Solution:

We have,

[tex]2x^4+2x^3-x^2-x[/tex]

The correct steps are shown below.

Step 1: Taking out x as common factor.

[tex]=x(2x^3+2x^2-x-1)[/tex]

Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.

[tex]=x(2x^2(x+1)-1(x+1))[/tex]

Step 3: Taking out (x+1) as common factor.

[tex]=x(2x^2-1)(x+1)[/tex]

She incorrectly factored -1 from the second group of terms.

Therefore, the correct option is B.

Answer:

2735.46 pence or £27.35

Step-by-step explanation:

if she uses 50.1 units a week, in 13 weeks she will use 651.3 units. the cost for 651.3 units is 2735.46 pence. We can round this to £27.35.

The required cost of the gas as of the 13-week usage of gas is 2735.46 pence.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

A unit of gas costs 4.2 pence. On average Ria uses 50.1 units of gas a week. She pays for the gas she uses in 13 weeks.

The cost of gas for 13 weeks, is given as,
= 4.2 × 50.1 × 13
= 2735.46 pence

Thus, the required cost of the gas as of the 13-week usage of gas is 2735.46 pence.

Answer:

the values 9 and 10 satisfy the given inequality.

Step-by-step explanation:

Given inequality is:

[tex]5<b-3[/tex]

In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality

Putting b = 8

[tex]5<8-3\\5 <5[/tex]

The inequality is not true for b=8.

Putting b=9

[tex]5<9-3\\5<6[/tex]

As the inequality is true for b=9, it satisfies the inequality.

Putting b=10

[tex]5<10-3\\5<7[/tex]

As the inequality is true for b=10, it satisfies the inequality.

Hence,

the values 9 and 10 satisfy the given inequality.

Explanation:

Answer:

Second Option, 4 23/40

Step-by-step explanation:

7 3/8 = 59/8

2 4/5 = 14/5

14 x 8 = 112

5 x 8 = 40

112/40

59 x 5 = 295

8 x 5 = 40

295/40

295 - 112 = 183

183/40 = 4 23/40

Answer:20

Step-by-step explanation:

I done 8+8+4=20 because 8 was 40% so I added another 8 that made a 80% so then I cut the 8 and half because all I needed was

20% then which would be half of 40% and I ended up with 20 and that equally gave me a hundred percent

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.
