Which equation represents the line that has a slope 5 and passes through the point (0,-2)
A. y = 5x - 2
B. y = x-3
C. y = 5x
D. y = -2x - 5
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)

Write the equation of a line in slope-intercept form that passes through (0, 7) and has a slope of -23.
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.

Write an equation of the line that passes through (2, -5) and is parallel to the line 2y = 3x + 10.
Answer:
Use the given slope and point to substitute into the point-slope formula y−y1=m(x−x1).
Slope-intercept form:
y=3x²+4x−25
Point-slope form:
y+5=(3x+10)⋅(x−2)

The coordinate of the vertices of parallelogram CDEH are C(-5,5), D(2,5), E(-1,-1), and H(-8,-1). What are the coordinates of P, the point of intersection of diagonals CE and DH?
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).

b) Which of these is the largest number?
1.201
A
1.2
B
1.21
с
1.2
D
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!

The graph shows the earning from a bake sale per item sold. Which equation represents the earnings from the bake sale?
Answer:
y = 5x
Step-by-step explanation:
Answer:
B, y= 5x
Step-by-step explanation:
If you look closely to the graph on the "bake sale items" side, when they sold 1 item they earned 5$. And when they sold 5 items they earned 25$. Which would mean every item they sold they get 5$ back which would make it B

Can someone please help me with this question!
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
A closed container has 3.06 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10–24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
A. 0.47 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10–24) = 4.73 ⋅ 10–1
B.0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10–24) = 5.1102 ⋅ 10–1
C.4.73 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10–24) = 4.73
D.5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10–24) = 5.1102
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

Plan A: Pay a $10.00 initiation fee per family, then pay a
discounted price of $1.75 per person to visit the
museum.
Plan B: Pay $2.75 per person per visit to the museum.
For each of the problems below, write an equation to
represent the situation and use the equation to solve the problem.
1. Jayden and his brother choose Plan A. During the summer, they spend a total of $38. How many times did the boys visit the museum?
2. Maria and her sister also like to visit the museum. They choose Plan B and spend a total
of $38.50. How many times did the girls visit the museum?
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.
f(x) = -x^2 - 7x - 5
Find f(-5)

How do I solve this?
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
