Answer:
Parallel lines have the same slope, so any line parallel to y = 7x - 3 will have slope 7. If your y intercept is 5, the line must go through (0,5), giving you y = 7x + 5.
Step-by-step explanation:
Which function is equivalent to q ( x ) = 9x 2 − 24x + 16?
q ( x ) = 9x 2 − 24x + 16 = (3x-4)^2
The closest answer to it would be
q ( x ) = (9x + 4) (x + 4)

oh god does anyone understand this? I need help it’s for a test and I wanna do good!!
Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
[tex] x = \frac{5 \sqrt{3} }{2} [/tex]
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
[tex]y = \frac{5}{2} [/tex]

1) Expand and simplify the following:
a)3(x squared plus 3x cubed - 2)
Answer:
3x³ + x² - 2
Step-by-step explanation:
a) 3(x squared plus 3x cubed - 2)
x squared = x²
3x cubed = 3x³
3(x squared plus 3x cubed - 2)
= 3(x² + 3x³ - 2)
= 3x² + 9x³ - 6
Rearrange according to power
= 9x³ + 3x² - 6
When the expression is divided by 3, it is equivalent to
3x³ + x² - 2

Becca is painting a birdhouse (rectangular prism) that has a height of 13cm, a width of 5 cm, and a length of 8cm. How much paint will she need if she only uses 1 coat? 26 sq. cm 0418 sq. cm 0 208 sq. cm
Answer:coo
Step-by-step explanation:Cooke.
The amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The surface area of rectangular prism can be given as,
[tex]SA=2(wl+hl+hw)[/tex]
Here, (w) is the width, (h) is the height and (l) is the length of the prism.
Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.
Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.
Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,
[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]
Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Triangle ABC is taken to triangle A'B'C' by a dilation. Which of these scale factors for the dilation would result in an image that was larger than the original figure? Select all correct answers. A
Answer:B
Step-by-step explanation:
For [K] > 0, the dilated image will be larger than the original image.
What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle ABC which is taken to triangle A'B'C' by a dilation.
After dilation by scale factor [K], the length of the sides of triangles change by the following rule -
A'B' = K(AB)
B'C' = K(BC)
C'A' = K(CA)
If K < 0, the image will shrink. If K > 0, the image will enlarge
Therefore, for [K] > 0, the dilated image will be larger than the orginal image.

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13

Given right triangle ABC with altitude BD drawn from vertex B to hypotenuse AC, find the lengths of AD, BD, and CD.
Keep as improper fraction
Answer:
AD = 3
BD = 10
CD = 17
Step-by-step explanation:
The requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Considering triangle BDC, we have:
[tex]BC^2 = BD^2 +CD^2[/tex]
This gives
[tex]24^2 = BD^2 +(25 - AD)^2[/tex]
[tex]576 = BD^2 +(25 - AD)^2[/tex] --------- (1)
Considering triangle ABD, we have:
[tex]7^2 = BD^2 + AD^2[/tex]
[tex]49 = BD^2 + AD^2[/tex] ---- (2)
Subtract (2) from (1)
[tex]576 - 49 = BD^2 -BD^2 +(25 - AD)^2 - AD^2[/tex]
[tex]527 = (25 - AD)^2 - AD^2[/tex]
Expand
[tex]527 = 625 - 50AD + AD^2 - AD^2[/tex]
[tex]527 = 625 - 50AD[/tex]
Collect like terms
[tex]50AD = 625 - 527[/tex]
[tex]50AD = 98[/tex]
Divide both sides by 50
[tex]AD = \frac{98}{50}[/tex]
Reduce fraction
[tex]AD = \frac{49}{25}[/tex]
Recall that:
[tex]49 = BD^2 + AD^2[/tex]
So, we have:
[tex]49 = BD^2 + (49/25)^2[/tex]
[tex]49 = BD^2 + 2401/625[/tex]
Collect like terms
[tex]BD^2 = 49 - 2401/625[/tex]
Take LCM
[tex]BD^2 = \frac{625 *49 - 2401}{625 }[/tex]
[tex]BD^2 = \frac{28224}{625}[/tex]
Take the square roots of both sides
[tex]BD = \frac{168}{25}[/tex]
Also, we have:
[tex]CD = 25 - AD[/tex]
This gives
[tex]CD = 25 - \frac{49}{25}[/tex]
Take LCM
[tex]CD = \frac{625 - 49}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Hence, the requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]

Which equation represents a parabola with the focus at (0, -1) and
the directrix y
= 1?
(1) x2 = -8y
(3) x2 = Sy
(2) x2 = - 4y
(4) x2 = 4y
Answer:
Step-by-step explanation:
The vertex is halfway between focus and directrix, at (0,0).
The equation has the form y = ax².
Focal length p = distance between focus and vertex = 1
p = 1/|4a|
1 = 1/|4a|
|a| = ¼
The focus lies below the vertex, so the parabola opens downwards and a<0.
y = -¼x²
Equation represents a parabola with the focus at (0, -1) and
the directrix y=1 is [tex]x^2=-4y[/tex]
Given :
a parabola with the focus at (0, -1) and the directrix y= 1
The standard equation of parabola is [tex]y-k=\frac{1}{4p} (x-h)^2[/tex]
Focus is at (0,-1)
The midpoint of focus and directrix is the vertex
Directrix is at y=1
Midpoint of (0,-1) and y=1 is (0,0)
So the vertex is (0,0) that is our (h,k)
Now we find the value of p
The distance between vertex (0,0) and focus (0,-1) is the value of p
focus and vertex are 1 unit away. So p=-1
we got h=0 and k=0 and p=-1
Replace all the value in the standard equation
[tex]y-0=\frac{1}{4(-1)} (x-0)^2\\y=\frac{-1}{4} x^2\\4y=-x^2\\x^2=-4y[/tex]
Equation represents a parabola with the focus at (0, -1) and
the directrix y=1 is [tex]x^2=-4y[/tex]
