Write an equation in point-slope form of the line that passes through the given point ( 3 , 4 ) and ( -1, -2 ).
Answer:
y - 4 = 3/2(x - 3)
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - 4 / -1 - 3
-6 / -4
= 3/2
y - 4 = 3/2(x - 3)
If it costs $16.50 to bowl twice with a shoe rental and $28.50 to bowl 4 times with a shoe rental how much does the shoes cost
Answer:
Shoe rent is $4.5
Step-by-step explanation:
Let the shoe rent is "x" which will remain the same irrespective of the number of bowling and "y" is bowling.
thus, x + 2y = 16.50
Rewrite, x = 16.50 - 2y
When bowling is 4 time then:
x + 4y = 28.50
Rewrite, x = 28.50 - 4y
Now solve both equations for the value of "y".
Thus, 16.50 - 2y = 28.50-4y
-2y + 4y = 28.50 - 16.50
2y = 12
y = 6
Insert y = 6 in the x - 2y = 16.50
x = 16.50 - 2y
x = 16.50 - 2 (6)
x = $4.5
Shoe rent is $4.5
What is the measure of Rsl?
Answer:
x = 13
Step-by-step explanation:
[tex](9x + 27) = (6x + 66) \\ 9x - 6x = 66 - 27 \\ 3x = 39 \\ x = \frac{39}{3} \\ x= 13 [/tex]
Find the value of x
Does anybody know this?
Answer:
x = 45 °
Step-by-step explanation:
We know that the sum of all angles if right angle triangle is 180 °.
90 ° + x + x = 180°
90 ° + 2 x = 180 ° ...( combine like terms)
2 x = 180 ° - 90 °.. ( subtract 90° from 180° )
2 x = 90°
x = 90° /2 ....( divide by 2 )
x = 45 °

3y+x=5, x-3y=12, y=3x-2, 6y-2x=7 which two of these are parallel??
Answer:
X-3Y=12 and 6Y-2X=7
Step-by-step explanation:
Step 1: Write all the equations in the form y=mx+c, where m represents the gradient.
Step 2: Find the equations with same value of m, ie., same gradient.
NB: Same gradient means that the lines are parallel.
Answer:
if you want to find which lines are parallel you must look at the slopes
Step-by-step explanation:
and you for this you must alone x
1) 3y=-x+5 slope is -⅓
2)3y=x-12 slope is ⅓
3)y=3x-2. slope is 3
4)6y=2x-7 slope is 2/6=⅓.
Finally the answer is 2 and 4 is parallel
which following algebraic statements are true
Answer:
All of them are true.
Step-by-step explanation:
x^2 y - z / x^2 is true. x^2, when divided by itself, cancels itself out, so the equation that is left is y - z.
For the second one, a/c + b/c is true because when you add a + b = it will change; it will be added together. the remaining c will stay the same, as it is the denominator/the same, so you keep it as it is.
For the final one, you distribute ^2 to (a+b), so they become a^2 + b^2.
This means that all of the statements are true.
Describe the transformation of f(x) to g(x).
(answers and graph in picture) PLSSSS HELP
Answer: b
Step-by-step explanation:
becuz now brainliest
The transformation of a function may involve any change. The correct option is A.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: y = f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k × f(x)Horizontal stretch by a factor k: y = f(x/k)Given the function of f(x) as sin(x), Now it can be seen the graph of the two functions is parallel, but the function f(x) has a y-intercept of 0, while h(x) has a y-intercept of 1. Therefore, we can write,
h(x) = f(x) + 1
The function is shifted up by 1 unit.
Hence, the transformation of the function is correctly described in the first option.

If y varies directly as x, and x=9 when y =15, find the value of y when x=33
Answer:
y = 55
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
15 = k*9
15/9 =k
5/3 = k
The equation is y = 5/3 x
Let x = 33
y = 5/3 * 33
y = 55

Solve the following for y: 4x + 2y = −2 (5 points)
y = −2x + 1
y = 2x + 1
y = −2x − 1
y = 2x − 1
Answer:
Step-by-step explanation:
4x + 2y = −2
Divide by two on both sides
2x+y = -1
subtract 2x from both sides
y = -1 -2x = -2x -1
Answer:
y = -2x - 1
Step-by-step explanation:
4x + 2y = -2
→ Minus 4x from both sides
2y = -4x - 2
→ Divide both sides by 2
y = -2x - 1

Wayne and Garth are planning to have a concert. They have found two good options. Option 1: Malcolm's Music Hall will pay them $100 for playing and add $15 per person in the audience. Option 2: Reggie's Reggae Room will pay them $350 for playing and add 10$ per person in the audience.
Answer:
50 people
Step-by-step explanation:
If you are to calculate the number of people that will come to the concert that will ensure option 1 and option 2 to yield equal amount
Let
x = number of people
Option 1:
Malcolm's Music Hall = 100 + 15x
Option 2:
Reggie's Reggae Room = 350 + 10x
Equate both options
100 + 15x = 350 + 10x
Collect like terms
100 - 350 = 10x - 15x
-250 = - 5x
x = -250/-5
x = 50 people
HELP FAST LOL HAHAHAH
Answer:
184
Step-by-step explanation:
First, note that the sides that are opposite to each other are congruent (this will come into play in a second). We can find the area of each triangle by doing 0.5(b)(h) (aka half * base* height). Since we've established tha opposite sides are congruent and the triangles are opposite to each other, they must be congruent. That means that the area is going to be the exact same for both triangles. So, we get the expression (0.5)(6)(4)(2), which comes out to 6*4 = 24. Then, to find the area of the 2 rectangles that are the sides, just do 5*10*2 = 100 square meters for both rectangles combines. Lastly, we need to find the area of the floor. The dimensions of the floor are 6 and 10, so we just do 6*10 = 60. Now, add all those numbers together. We get 100+60+24 = 184. Hope this helps! Let me know if anything is still confusing.
