A line passes to the point (4,6) and has a slope of -3/4. Which is the equation of the line
Answer:
Step-by-step explanation:
use point-slope formula [ y- y1 = m(x - x1) ] with the point you are given as point 1 (x1,y1) = (4,-6) and the slope m that you are also given m = -3/4
y-y1 = m(x -x1)
y-(-6) = -3/4(x -4)
y + 6 = -3/4(x-4)
you can work this toward the slope-intercept formula of y = mx +b by doing the following
y + 6 = -3/4x +3 (distribute the -3/4)
y = -3/4x + 3 -6 ( move the 6 to the other side )
y = -3/4x - 3
there you go :) choice 1 looks good if you're still able to put in the answer
This diagram shows a right square pyramid and some of its dimensions. What is the volume of the pyramid?
A) 48 cubic inches
B 60 cubic inches
C 144 cubic inches
D) 180 cubic inches
Please I need help :(
Answer:
Volume of square Pyramid is 48 cubic inches.
Option A is correct option.
Step-by-step explanation:
Height of Pyramid = 4 in
Length of Base = 6 in
We need to find volume of square pyramid
The formula used is:
[tex]Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h[/tex]
Where A is area of base and h is height.
[tex]Area\: of\: Base =(Length)^2= 6^2 = 36[/tex]
Now, putting values of A = 36 and h = 5 and finding volume
[tex]Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h\\Volume\: of\: Square\: Pyramid=\frac{1}{3}\times 36 \times 4\\Volume\: of\: Square\: Pyramid=12 \times 4\\Volume\: of\: Square\: Pyramid=48 \: cubic\:inches[/tex]
So, Volume of square Pyramid is 48 cubic inches.
Option A is correct option.

The movie theater capacity is at most 435. write an Inequalitie
Answer:
x ≤ 435
Step-by-step explanation:
Let the capacity of the theater be represented by x. The movie theater has a capacity of 435, which implies that it can hold nothing more than or maximum of 435 people. Thus the number of people for the theater could be less than 435, but not more than 435.
Expressing this with inequality, we have;
x ≤ 435
where x is the movie theater capacity.
SOMEONE PLEASE HELP ME WITH THIS!!!!! ITS GEOMETRY
Answer:
KG = 7 (A)
m KIH = 28 (B)
m JIH = 96 (D)
m HKI = 68 (B)
m KJI = 84 (C)
Step-by-step explanation:
Notice that the triangle HKJ is identical to HIJ. Since there are lines drawn to each other and both triangles are identical, the lines KG and GI are the same. This means that it is 7.
The triangle KGJ is identical with IGH. Using the recognise angle property, we know that angle JKI is the same as KHI. This means that it is 28.
Angle JIH is the same as angle JKH. Since JKH is 180 - (KHI or 84), we know that the angle JIH is 96.
We can find angle HKI by subtracting 96 by 28 because we know that angle HKI is the same as JIH. This gives us 96-2 8 = 68.
Angle KJI is the same as KHI which is 84. Therefore, KJI is also 84.

49x2 - 81 is an example of the difference of two
squares. All polynomials that are a difference of two
squares factor in a very specific way. Which of the
following would represent the factorization of a polynomial
that was the difference of two squares.
(x - 25)
(9x – 100)
(25x – 4)(25x – 4)
(x-4) (x-9)
(4x + 3)(4x - 3)
Answer:
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
Step-by-step explanation:
Formulas are used to factorize the polynomials.
In the given question, we can see a difference of squares
the difference of squares can be factorized using the formula
[tex]a^2-b^2 = (a+b)(a-b)[/tex]
Here a^2 and b^2 are squares and factorized as sum and difference of numbers.
So in the given options,
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

Evaluate (5 + 2) to the power of 2 - 40 + 3 =
Answer:
12
Step-by-step explanation:
(5+2)^2 - 40 + 3
= 7^2 - 40 + 3
= 49 - 40 + 3
= 49 - 40
= 9+3
= 12
The first company charges $40 per backpack and a $10 shipping fee for the order and the second company charges $38 per backpack and $16 shipping fee. How many backpacks would a customer need to order from either company so that the cost of the order was the same from both companies
Answer: 3
Step-by-step explanation:
Multiply $40 by 3 then add 10 to get 130.
Multiply $38 by 3 then add 16 to get 130.
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies is 3 backpacks.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
First company:
Charges per backpack = $40
Shipping fee = $10
We can write an equation for the cost of x backpacks of the first company:
10 + 40x _____(1)
Second company:
Charges per backpack = $38
Shipping fee = $16
We can write an equation for the cost of x backpacks for the second company:
16 + 38x ______(2)
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies:
From (1) and (2) we get,
10 + 40x = 16 + 38x
Subtract 10 on both sides
10 + 40x - 10 = 16 + 38x - 10
40x = 6 + 38x
Subtract 38x on both sides.
40x - 38x = 6
2x = 6
Divide 2 on both sides.
x = 3
Thus,
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies is 3 backpacks.

Molly's Custom Kitchen Supplies sells handmade forks and spoons. It costs the store $1.70 to buy the
supplies to make a fork and $1.30 to buy the supplies to make a spoon. The store sells forks for $5.60
and spoons for $5.40. Last April Molly's Custom Kitchen Supplies spent $37.90 on materials for forks
and spoons. They sold the finished products for a total of S147.20. How many forks and how many
spoons did they make last April?
Write the equation for the cost of making forks and spoons:

spoons:

They made

9514 1404 393
Answer:
7 forks20 spoonsStep-by-step explanation:
Let x and y represent the numbers of forks and spoons made, respectively.
The cost of materials is ...
1.70x + 1.30y = 37.90
The revenue from sales is ...
5.60x + 5.40y = 147.20
You can solve these by any of your favorite methods. A graph is attached. It shows the solution is (x, y) = (7, 20).
They made 7 forks and 20 spoons.

The equation coefficients are not "nice" multiples of each other, so elimination and substitution will require multiplying both equations by some numbers. If we're going to that trouble, we may as well use Cramer's Rule or a variation of the "cross multiplication method". The latter is relatively straightforward and can be easy to remember. It tells you the solution to ...
ax +by +c = 0
dx +ey +g = 0
is ...
1/(ae-db) = x/(bg-ey) = y/(cd-ga)
Here, that becomes ...
1/(1.70·5.40-5.60·1.30) = x/(1.30·(-147.20)-5.40·(-37.90))
= y/(-37.90·5.60-(-147.20·1.70))
1/1.9 = x/13.3 = y/38
x = 13.3/1.9 = 7 . . . number of forks
y = 38/1.9 = 20 . . . number of spoons
__
The above solution formula may be more easily remembered in terms of the cross-multiplication pattern that gives the method its name. When the coefficients are written in two rows of four, with the last being a repeat of the first:
a b c ad e g deach of the three denominators (of 1, x, and y) is the difference of products in adjacent columns, formed in an X fashion: ae-db, bg-ec, cd-ga. Note that the equations are written in "general" form, which is similar to "standard" form, but with all of the non-zero terms on the left of the equal sign. (This has the effect of changing the sign of the constants: 1.7x+1.3y=37.9 ⇒ 1.7x+1.3y-37.9=0)
Help please, I'm stuck on this :/
Do you have a calculator? you can solve it by substituting x.
y=16x^2
0: y = 16(0)^2 = 16(0) = 0
(x = 0 , y = 0)
0.5: y = 16(0.5)^2 = 16(0.25) = 4
(x = 0.5 , y = 4)
1: y = 16(1)^2 = 16(1) = 16
(x = 1 , y = 16)
1.5: y = 16(1.5)^2 = 16(2.25) = 36
(x = 1.5 , y = 36)
2: y = 16(2)^2 = 16(4) = 64
(x = 2 , y = 64)
2.5: y = 16(2.5)^2 = 16(6.25) = 100
(x = 2.5 , y = 100)
3 : y = 16(3)^2 = 16(9) = 144
(x = 3 , y = 144)
4: y = 16(4)^2 = 16(16) = 256
(x = 4 , y = 256)
if you multiply a negative number by itself, it will become positive. So, -4, -3, -2.5, -2, -1.5, -1, -0.5 will be the same as the positive 4, 3, 2.5, 2, 1.5, 1, 0.5.
I'm not sure about the pattern, but if you graph it, it'll be symmetrical across the y-axis.
