Answer:
y = -1/20(x + 3)²Step-by-step explanation:
Consider the parent function:
y = x²The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
y = -x²The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
y = -(x + 3)²Since all the options have 1/20 as a coefficient, our function is:
y = -1/20(x + 3)²This is option B
-x + y = 3 and 3x+ y = -1
Answer: {y = x + 3, y = -3 x - 1}
{x + 3 = y, 3 x + y + 1 = 0}

B
156°
А

0
Answer:
The missing angle is 24 degrees
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
x+156 = 180
Subtract 156 from each side
x+156-156 = 180- 156
x = 24
The missing angle is 24 degrees

Which equation represents a line that passes through (2, -0.5) and has a slope of 3? Oy - 2 = 3(x+ -0.5) 0 y 3= 2(x + 0.5) 0y + 7 = 3(x - 2) Oy + 7 + 2(x - 3)
Answer:
y=3x-6.5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-0.5)=3(x-2)
y+0.5=3x-6
y=3x-6-0.5
y=3x-6.5
The slope of a line indicates the measure of the steepness and the direction of the line. The slope of any line can be calculated using any two distinct points lying on the line. The equation is y = 3x-6.5. The correct option is D.
What is equation of a line?The equation of a line is an algebraic form which represents the set of points, which together form a line in a coordinate system. The equation of line is a linear equation with a degree of one. It can be formed with the help of the slope and a point on the line.
The equation of a line passing through the point and slope is given as:
(y - y₁) = m (x - x₁)
(y - -( 0.5)) = 3 ( x - 2)
(y + 0.5) = 3 (x - 2)
(y + 1/2) = 3 (x - 2)
or
y + 0.5 = 3x - 6
y = 3x - 6.5
Thus the correct option is D.

Coach Kawa collected data on 5 of his baseball players. The points show shoe size and the number of runs scored this week by the 5 players.
Answer:
Carmen
Step-by-step explanation:
Given
See attachment for plot
Required
Player with the most runs
The number of runs is represented by the y coordinates.
So, the player with the most runs has the highest y coordinate.
From the attached plot, the y coordinate of each player is:
[tex]Paulo = 5[/tex]
[tex]Rebecca = 4[/tex]
[tex]Nardine = 9[/tex]
[tex]Jason = 10[/tex]

Answer:
Angle MJK = 64°
Step-by-step explanation:
In ∆MJL & ∆LJK,
JL= JL ...(common side)
Angle JML = Angle JKL ....( each 90°)
MJ = JK ....( Both measures 7)
Hence, by SAS criteria, ∆ MJL = ∆ LJk
.°. by C.P.C.T , ∠MJL = ∠LJK = 32°
Also,
∠MJK = ∠MJL+∠LJK
∠MJK = 32°+32°
∠MJK = 64°what is 27 divided by 6 long division

30. Work out the next two terms, giving your answers as fractions decimals or percentages. The sequence below is linear. 0.6 75% 9 10 \ (2 marks)
Answer:
The next two terms are: 1.05 and 1.20
Step-by-step explanation:
Given
[tex]Sequence: 0.6, 75\%, 9/10[/tex]
Required
Write out the next two terms
Since it is a linear sequence; first, we calculate the common difference (d)
[tex]d = 75\% - 0.6[/tex] or [tex]d = 9/10 - 75\%[/tex]
Express as decimals
[tex]d = 0.75 - 0.6[/tex] or [tex]d = 0.9 - 0.75[/tex]
[tex]d = 0.15[/tex] (in both cases)
So, we add 0.15 to 9/10, to get the next term
[tex]Next = 9/10 + 0.15[/tex]
[tex]Next = 0.9 + 0.15[/tex]
[tex]Next = 1.05[/tex]
Add 0.15 to 1.05, to get the next term
[tex]Next = 1.05 + 0.15[/tex]
[tex]Next = 1.20[/tex]
The next two terms are: 1.05 and 1.20

Guengle works in urban landscape design a truck arrived pouring a cone shaped pile of gravel six feet high with a diameter at the base of 8.2 ft how much gravel was delivered use pie\
Answer:
[tex]105.56\ ft^3[/tex] of gravel was used.
Step-by-step explanation:
Given that,
The height of a cone, h = 6 feet
The diameter of the base of cone, d = 8.2 feet
Radius, r = 4.1 feet
We need to find the amount of gravel was delivered. The volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 4.1^2\times 6\\\\V=105.56\ ft^3[/tex]
So, [tex]105.56\ ft^3[/tex] of gravel was used.
