What is an equation in point slope form of the line that passes through the point (6,-2) and had a slope of 3
Answer:
y - 6 = 3(x + 2)
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: m(slope) = 3, (6, -2)
(x1, y1) = (6, -2)
Input the given values of the slope and the point into the equation for point-slope form:
y - (-2) = 3(x - 6)
y + 2 = 3(x - 6)
The equation written in point-slope form is: y + 2 = 3(x - 6)
The drama group has 909090 minutes to practice two scenes. They want to practice the pirate scene 444 times, and each time takes 131313 minutes. The mermaid scene takes 777 minutes. How many full times can the group practice the mermaid scene? times
Answer: 5.43 minutes
Step-by-step explanation:
Number of minutes for the drama group = 90 minutes
Number of times to practice the pirate scene = 4
Time taken to practice the pirate scene = 13
The number of minutes used for pirate scene will be:
= 4 × 13 = 52 minutes
The number of full times that the group can practice the mermaid scene will then be:
= (90 - 52) / 7
= 38 / 7
= 5.43 minutes
The second new path will increase access to the gazebo. It will be perpendicular to the the existing path and pass through g (7,2). Which equation represents which this new this path on the map
A.y=-4x+30
B.y=-1/4x+15/4
C.y=1/4x+1/4
D.y=4x-26
Answer:
C. y = 1/4x + 1/4
Step-by-step explanation:
Just did it on Edmentum and got it right
Answer:
C. y=1/4x+1/4
Step-by-step explanation:
Like the first path, this path will have a slope that is the opposite reciprocal of -4, the slope of the path passing through F(4,14) and G(7,2).
Substitute 1/4 and the coordinates of point G into slope-intercept form, and solve for b
Then, substitute 1/4 for m and 1/4 for b to find the equation of the line that’s perpendicular to the original path and passes through G(7,2)

Does (3,6) make the equation y = 2x true? ves
Answer:
Yes.
Step-by-step explanation:
In order to check if an equation is true, plug in the corresponding values for x and y.
Coordinates are written as (x, y). So, x = 3 and y = 6.
Plug in these values to the equation.
6 = 2 * 3
Multiply 2 and 3 to simplify:
6 = 6
This shows that the equation is true when given (3, 6)

Step-by-step explanation:
The point A (−5,4) is reflected over the point (−2,5) and its image is point B. What are the coordinates of point B?
Answer:
The coordinates of B are (1,6)
Step-by-step explanation:
Point Reflection
Given the point P(x,y) and its reflection P'(x',y') with respect to the point C(xc,yc), C is the midpoint of the segment PP'.
This means the coordinates of C are:
[tex]\displaystyle x_c=\frac{x+x'}{2}[/tex]
[tex]\displaystyle y_c=\frac{y+y'}{2}[/tex]
If the coordinates of the midpoint are given, then the endpoint P' can be found solving for x' and y':
[tex]x'=2x_c-x[/tex]
[tex]y'=2y_c-y[/tex]
The point P' is the reflection of P over C.
We are given the coordinates of A(-5,4) and the point (-2,5). We need to find the coordinates of point B(x',y'). Let's use the formulas as if A was point P and C=(-2,5):
[tex]x'=2(-2)-(-5)=-4+5=1[/tex]
[tex]y'=2(5)-4=10-4=6[/tex]
The coordinates of B are (1,6)
Copland competes in 27 swimming events this
season. He wins either first place or second
place in each event. Copland has 3 more first-
place wins than second-place wins. In how
many events did he win first place, and in how
many did he win second place?
Answer:
15 wins 12 2nd because subtract 3 from 27 that's 24 divide that by 2 its 12 so you add the extra 3 to 12 and that's 17

Egg noodles: Package A is 12 oz. for $0.99. Package B is 2 lbs. for $2.56
Which is the better deal
Answer:
Package A
Step-by-step explanation:
$0.99 ÷ 12oz = 0.0825
2lb = 32oz
$2.56 ÷ 32oz = 0.0800
therefore the package a is a better deal
Consider the words typically associated with geometry.
Are there any words that would be hard to precisely
define? What words can you think of?
Answer:
Point, line and plane
Step-by-step explanation:
Words are defined using other defined words or terms. However, these three terms are very difficult to find other words to describe. Without using other terms, we create circular definitions; thus these are called the "undefined terms" of geometry.
Hope this helps :)
What is the vertex of the quadratic function f(x)=x2+6x+16? Write your answer
as an ordered pair, (x,y).
Answer:
The vertex of the quadratic function is:
[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=x^2+6x+16[/tex]
As the vertex of the form [tex]y=ax^2+bx+c[/tex] is defined as:
[tex]x_v=-\frac{b}{2a}[/tex]
As the quadratic function of parabola params are
[tex]a=1,\:b=6,\:c=16[/tex]
so
[tex]x_v=-\frac{b}{2a}[/tex]
[tex]x_v=-\frac{6}{2\cdot \:1}[/tex]
[tex]x_v=-3[/tex]
Putting [tex]x_v=-3[/tex] to determine [tex]y_v[/tex]
[tex]y_v=\left(-3\right)^2+6\left(-3\right)+16[/tex]
[tex]y_v=3^2-18+16[/tex]
[tex]y_v=9-2[/tex]
[tex]y_v=7[/tex]
Therefore, the vertex of the quadratic function is:
[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]
Use the graph to evaluate the function for the given input value.

The triangles are similar. Find
the missing side length x.
Answer:
x = 66
Step-by-step explanation:
The similarity ratio is DO/PA = 27/18 ➡3/2
So DT/PN ➡ x/44 = 3/2
132 = 2x divide both sides by 2
x = 66
Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below. 900 + 900(1.015 • 2) What is the correct amount Vince will pay back altogether? Explain the error in Vince's expression. A. 00:00 $903; Vince should have subtracted the first 900 from the amount he will pay. B. 00:00 $913.50; Vince multiplied by the wrong number of years. C. 00:00 $927; Vince wrote the wrong number to represent the interest rate. D. 00:00 $1,813.50; Vince forgot to add the initial $900 to the amount he will pay.
Answer: C. 00:00 $927; Vince wrote the wrong number to represent the interest rate.
Step-by-step explanation:
Given that:
Amount borrowed (p) = 900
Simple interest (r) = 1.5% = 0.015
Time (t) = 2 years
Amount he'll pay back (A) :
A = P(1 + rt)
A = 900(1 + 0.015(2))
A = 900(1 + 0.03)
A = 900(1.03)
A = $927

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey? Complete the explanation. When entering the equation, use y to represent how many servings he can make and x to represent how many pounds of ground turkey he has.
Answer:
12 servings
Step-by-step explanation:
Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey?
From above question:
2.5 pounds of ground turkey = 5 servings
6 pounds of ground turkey = x
Cross Multiply
2.5 × x = 6 × 5
x = 6 × 5/2.5
x = 12 servings
Hence, 6 pounds of ground turkey can make 12 servings.
Completing the explanation.
The equation is
5x = 2.5y
where:
x = represent how many pounds of ground turkey he has = 6 pounds
y = to represent how many servings he can make
Hence,
5 × 6 = 2.5y
y = 5 × 6/2.5
y = 12 servings
