I GIVE BRAINLIEST!!!

explain your steps!!

Answer:

y = -23x + 7

Step-by-step explanation

We are using the equation y = mx + b.

The slope (m) is -23, so it would be y = -23 + b.

b is the y-intercept, and the ordered pair that gives us the y-intercept is (0,7).

Remember that the y-intercept is what the y-coordinate is equal to when the x-coordinate is 0.

Answer:

Step-by-step explanation:it 10 cause there is no negative in this equation it’s only subtraction and you subtract and you get the number 10 I got this right

Answer:

Step-by-step explanation:

The correct answer is not the first answer, but the second answer in the middle. The third answer is the correct one because, since it has the correct exponent, that is, 0.51 grams.

_________________________________________________________

The approximate total mass is the number of atoms multiplied by the weight of an atom.

The approximate overall mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom) which is equivalent to a mass of 0.51 grams. (1.67 10⁻²⁴ grams/1 atom) = 0.51102 g ≈ 0.51 g

Answer: B. 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1

Answer:

long story short, the answer is B, 0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10-24) = 5.1102 ⋅ 10-1

Here, the graph shows d is greater 2.75 but not equal to 2.75.

Answer:

19.63

Step-by-step explanation:

Find the radius

5 / 2 = 2.5

2.5² = 6.25

6.25 × π = 19.63

Answer: x = 15; y = 32; z = 2.5

see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.

=> this parallelogram is a square

=> the diagonal lines of the parallelogram   are perpendicular to each other

=> m∠1 = 90°

⇔ 3y - 6 = 90

⇔ 3y = 96

⇔ y = 32

because this is a square

=> 3x = 18z = 45°

=> x = 15

    z = 2.5

Answer:

your answer would be 7.25

Step-by-step explanation:

y = the cost of all visits to the meuseum

x = the number of visits

Plan A calls for $1.75 per per, per visit. There are two people so each visit for will cost $3.50 for both. This is the Slope of your line. This plan also requires an initial cost of $10 for 0 visits, this is your y intercept, or b in the point Slope form.

Put all that together for y = 3.5x + 10

The 1st question requires finding the number of visits possible for $38.00, this is the y value at x visits.

Solve

38.00 = 3.5x + 10. Subtract 10 from both sides

28.00 = 3.5x. divide both sides by 3.5

x = 8 visits for each Hayden and his brother.

Plan B is just paying $2.75 per person, per visit. For both Maria and her sister the cost would be $5.50 per visit. This is the Slope.

There is no initial cost so the equation is

y = 5.50x

How many times can they go for $38.50

$38.50 = 5.50x solve for x

x = 7 visits for Maria and her sister. They should have gone with plan A. They would have been able to go to the museum one more time and each saved a quarter.

Answer:

I need to know the cost of one visit

Answer:

answer is in the step by step explanation.

Step-by-step explanation:

40 feet is the diameter so 20 feet is radius. 2 times pi times 20 is 125.663706144. if pi is 3.14 then it's 125.6. I hope that answered your question.

Answer:

12

Step-by-step explanation:

Keep in mind the rules of PEMDAS

P (parenthesis)

E (exponents)

M (multiply)

D (division)

A (addition)

S (subtraction)

Because parenthesis is the first operation in PEMDAS, you would start by calculating inside the parenthesis

We can start with the numbers inside the first parenthesis

(33 - 2 × 7)

Start by multiplying 2 and 7 because the M comes before the S

(33 - 2×7)= (33- 14)

Now subtract 14 from 33

(33-14) = 19

Step 2: Calculate inside the second parenthesis

(5 × 3 - 22)

Multiply first

(5 × 3 - 22)= (15 - 22)

Subtract!

(15 - 22)= -7

Now add the final number together

(why? There is an addition sign between the two parenthesis ordering us to add the final numbers together)

19 + (-7)

19-7

12

I hope this helps!!!

Answer:

Step-by-step explanation:

Simplifying

4(t + 1) = 6(g + -4)

Reorder the terms:

4(1 + t) = 6(g + -4)

(1 * 4 + t * 4) = 6(g + -4)

(4 + 4t) = 6(g + -4)

Reorder the terms:

4 + 4t = 6(-4 + g)

4 + 4t = (-4 * 6 + g * 6)

4 + 4t = (-24 + 6g)

Solving

4 + 4t = -24 + 6g

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + 4t = -24 + -4 + 6g

Combine like terms: 4 + -4 = 0

0 + 4t = -24 + -4 + 6g

4t = -24 + -4 + 6g

Combine like terms: -24 + -4 = -28

4t = -28 + 6g

Divide each side by '4'.

t = -7 + 1.5g

Simplifying

t = -7 + 1.5g

Answer:

y=-3.2x+6

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

because the -2 is where the point is and the slope will start there so when you draw a line the line will pass by (0,-2)

Given:

Vertices of a parallelogram are C(-5,5), D(2,5), E(-1,-1), and H(-8,-1).

P is the intersection point of diagonals CE and DH.

To find:

The coordinates of P.

Solution:

We know that, diagonals of a parallelogram always bisect each other. It means the intersection point of the diagonal is the midpoint point of both diagonals.

We can find the midpoint of either diagonal CE or diagonal DH to get the coordinates of intersection point of diagonals, i.e. P.

So, point P is midpoint of CE. So,

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]P=\left(\dfrac{-5+(-1)}{2},\dfrac{5+(-1)}{2}\right)[/tex]

[tex]P=\left(\dfrac{-5-1}{2},\dfrac{5-1}{2}\right)[/tex]

[tex]P=\left(\dfrac{-6}{2},\dfrac{4}{2}\right)[/tex]

[tex]P=\left(-3,2\right)[/tex]

Therefore, the coordinates of point P are (-3,2).

Answer:

3rd one

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

For the relationship to be a function then each value of x must map to exactly one unique value of y.

This is true for the points except Z andT, where

x → 3 (Z) and x → 5 (T)

This means the relation is not a function

Answer:

21 weeks or 5 months 1 week (7 days) to save 1250

Step-by-step explanation:

1250-200 (the amount he has)

1050 which is what he needs to save for

1050/50 = 21

Answer:

C

Step-by-step explanation:

If you put zeros at the end of the decimals or look at the digits, it can really make it easier.

A=1.201

B=1.200

C= 1.210

D= 1.200

Now, you see that in the hundredths place for C that there's 1 while the others have 0? That's how you can solve it!
