Answer: At point (0,12) line q cross the y-axis.
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d) :
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
Given: Line q goes through points (-3, 3) and (-5, -3).
Equation of line q:
[tex](y-3)=\dfrac{-3-3}{-5(-(-3)}(x-(-3))\\\\\Rightarrow\ (y-3)=\dfrac{-6}{-5+3}(x+3)\\\\\Rightarrow\ (y-3)=\dfrac{-6}{-2}(x+3)\\\\\Rightarrow\ y-3=3(x+3)[/tex]
When line crosses y-axis , x=0 .
So,
[tex]y-3=3(3)\\\\\Rightarrow\ y-3=9\\\\\Rightarrow\ y=9+3\\\\\Rightarrow\ y=12[/tex]
Hence, At point (0,12) line q cross the y-axis.

Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price
Answer:
$6
Step-by-step explanation:
Original price of the pineapple = $20
Percentage off = 70%
Amount discounted = 70% of $20
Amount discounted = 0.7 * 20
Amount discounted = $14
Sale price = Original price - Discount
Sale price = $20 - $14
Sale price = $6
Hence the sale price was $6

A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
Answer:
Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
Step-by-step explanation:
Given: A man sold a fan for [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].
To find: The cost price of the fan
Solution:
We have,
Selling price, S.P., of the fan [tex]= \text{Rs.} 400[/tex]
Loss [tex]=15\%[/tex]
We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]
Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]
So, [tex]15=(\frac{x-400}{x})\times 100[/tex]
[tex]\implies 15x=100x-40000[/tex]
[tex]\implies 100x-15x=40000[/tex]
[tex]\implies 85x=40000[/tex]
[tex]\implies x=\frac{40000}{85}[/tex]
[tex]\implies x= 470.59[/tex]
Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below.
(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)
= 3y2 – 12y2
= –9y2
Is the student’s work correct?
Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!
Step-by-step explanation:
Answer:
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
Step-by-step explanation:
Given the expression
3-6y² and y²+2
We have to find the product of 3-6y² and y²+2
Clara's Solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)
= 3y² – 12y²
= -9y²
NO!
The student's work is INCORRECT!
Clara did not imply the correct distribution of multiplying the terms in the first step.
Here is the correct solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)
= 3y² – 12y² + 6 - 6y⁴
= - 6y⁴ - 9y² + 6
Therefore,
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

PLZZZZZZ HELP ME
Step-by-step explanation:
The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines

A quadratic function has one root at 5 and has a vertex point at (7, 2).
What is the value of “a”?
[tex]y = a {(x - h)}^{2} + k[/tex]
where a-term determines the shape of graph.
h-term determines the change of graph for x-axis.
k-term determines the change of graph for y-axis.
Vertex of the graph is at (h,k).
Substitute the vertex value in the equation.[tex]y = a {(x - 7)}^{2} + 2[/tex]
We need to find the value of a-term. We have the given root which we can substitute in the equation.
Also the roots are on x-axis, meaning that the y-value for roots must be 0.
Substitute (5,0) in the equation.[tex]0 =a {(5 - 7)}^{2} + 2 \\ 0 =a {( - 2)} ^{2} + 2 \\ 0 = 4a + 2[/tex]
Solve for a-term.[tex]4a + 2 = 0 \\ 4a = - 2 \\ a = \frac{ - 2}{4} \\ a = - \frac{1}{2} [/tex]
Therefore the value of a is - 1/2. Rewrite the equation as we get the answer.
Answer[tex] \large \boxed{y = - \frac{1}{2} {(x - 7)}^{2} + 2}[/tex]

The figure below depicts a triangle formed by the labeled
vertices. If each vertex point of the triangle is multiplied
by what would be the area of the resulting triangle?

(3, 3)
0.0)
09
0 13.5
0 15
18
O 27
9514 1404 393
Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

Answer: 3:2
Step-by-step explanation:
the base ratio of unused tape to used tape is 24:16.
then we have to simplify,
both 16 and 24 can be divided by eight,
24 divided by eight is 3
16 divided by eight is 2
therefore, our simlpified ratio is 3:2

A class trip is planned for a cinema visit.
1/4 of the people walk to it.
1/3 of the people, get the bus.
The remaining 60 people get a lift in a car.
Calculate the number of pupils who get the bus and who walk to the cinema.
Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.
Step-by-step explanation:
Let's suppose that there are a total of N pupils.
We know that N/4 walk to the cinema.
We know that N/3 get the bus to the cinema.
And the remainder is equal to 60 people.
Then:
N - N/4 - N/3 = 60
N*(1 - 1/4 - 1/3) = 60
N( 12/12 - 3/12 - 4/12) = 60
N*( 5/12) = 60
N = (12/5)*60 = 144
Then the number of pupils that walk to the cinema is N/4, or:
144/4 = 36
And the number of pupils that get the bus is N/3, or:
144/3 = 48.

Discriminate
Answer:
D = 41
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
D = 5² - 4(1)(- 4) = 25 + 16 = 41

Answer:
4 sqrt 2
Step-by-step explanation:
Answer:
4 sqrt(2)
Step-by-step explanation:
This is a special triangle 45, 45, 90 therefore you just multiply the sides by sqrt(2) to find the hypotenuse so it will be 4 sqrt(2)
Another way to do it is by Pythagorean triangle which will still lead to 4 sqrt(2)

An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
