Answer:
y=[tex]\frac{-4}{5}[/tex]x+7
Step by Step Explanation:
Slope intercept form is y=mx+b
So to convert this to slope-intercept form, you would first need to move the x value to the other side of the equation through subtracting it on both sides. This would make the equation 10y = -8x +70
Next, you would divide both sides by 10 to get the y integer alone. This would make the equation y=[tex]\frac{-8}{10}[/tex]x + 7
Lastly, just simply that fraction before the x integer, and you get your answer!

A certain company designs and ships boxes of golf balls. Each box must weigh 540 grams. Write two absolute value expressions that represent the number of grams a box weighing g grams is away from the desired weight. Select all that apply. Multiple select question. cross out A) 540−||g|| cross out B) ||g||−540 cross out C) ||540−g|| cross out D) ||g+540|| cross out E) ||g−540||
Answer:
|540 - g|
|g - 540|
Step-by-step explanation:
Given that:
Weight of box = g
Desired weight = 540
Hence, to obtain the difference between the weight of the box and the desired weight ; the result could either be lesser or larger then desired weight ; However , since we do not know If it is lesser or higher, then we take the absolute value ; so that we always obtain a positive value.
The difference will thus be either ;
Weight of box - desired weight : |g - 540|
OR
deaired weight - weight of box : |540 - g|

Answer:
x = 20
Step-by-step explanation:
(see attached for reference)
From the diagram, we can see that angle A and angle C are base angles of an isoceles triangle. Hence they are equal. i.e
m∠A = m∠C
(3x+10) = (2x+30)
3x+10 = 2x+30 (subtract 2x from both sides)
3x + 10 - 2x = 30
x + 10 = 30 (subtract 10 from both sides)
x = 30 - 10
x = 20

Yeah you have a square garage 366 ft.² floor space she recently built in addition to the garage is the square but I have 50% more force base what is the length of one side of the garage originally what is the length of one side of the garage now what was the percent increase in the length of one side
Answer:
a) The original length of the garage is 19.13 feet.
b) The new length of the garage is 23.43 feet.
c) Percentage increase in the length of one side is 22.5%.
Step-by-step explanation:
The original area of the garage = 366 [tex]ft^{2}[/tex]
a) Area of a square = length x length (since it has equal length of sides)
= [tex]l^{2}[/tex]
So that;
366 = [tex]l^{2}[/tex]
l = [tex]\sqrt{366}[/tex]
= 19.131
The original length of the garage is 19.13 feet.
b) 50% more force base = 50% x 366
= 0.5 x 366
= 183
The new area of the garage = 366 + 183
= 549 [tex]ft^{2}[/tex]
So that;
549 = [tex]l^{2}[/tex]
l = [tex]\sqrt{549}[/tex]
= 23.431
The new length of the garage is 23.43 feet.
c) Increase in the length of one side = 23.431 - 19.131
= 4.3 ft
Percentage increase in the length of one side = [tex]\frac{4.3}{19.131}[/tex] x 100%
= 22.48 x 100%
≅ 22.5%
Percentage increase in the length of one side is 22.5%.

What is the factorization of the polynomial below?
16x^2-9
Answer:
(4x+3) × (4x−3)
Step-by-step explanation:
The explanation is on the screenshot if you need it
The resulting simplified form of the expression is (4x +3)(4x-3)
Given the polynomial equation 16x^2-9
This can be expressed as the square of monomials as shown:
16x^2 = (4 * 4 * x * x)
16x^2 = (4x)^2
Similarly, 9 = 3^2
Substituting into the expression, we will have:
16x^2-9 = (4x)^2 - 3^2
According to difference of two square a^2 - b^2 = (a+b)(a-b)
(4x)^2 - 3^2 = (4x +3)(4x-3)
Hence the resulting simplified form of the expression is (4x +3)(4x-3)

Step-by-step explanation:
From the. Table provided :
500 500
450 550
400 600
350 650
X = number of children
Y = Number of Adult
The sum of both x and y gives 1000 in all 4 scenarios :.

El diámetro de una bacteria de tamaño intermedio es de unos 0,003 mm, pero los
virus son todavía más pequeños; por ejemplo, el de la poliomielitis mide 0,000 015mm
de diámetro. Determina la diferencia, en milímetros, entre el diámetro del virus de la
polio y el de una bacteria común. Expresa en notación científica.
Answer The value of the difference in millimeters between the diameter of the virus of polio and a common bacterium, expressed in scientific notation is: 2.985 * 10.03 mm.
The difference , in millimeters , between the diameter of the polio virus and that of a common bacterium is calculated by subtracting the two diameter values from the largest minus the smallest as follows:
Intermediate diameter of a common bacteria = 0.003 mm
Poliomyelitis virus diameter = 0.000015 mm
Difference =? mm in scientific notation
Difference = 0.003 mm - 0.000015 mm = 0.002985 mm
At the express the result in scientific notation is:
0.002985 mm = 2.985 * 10-3 mm.
Find a so that the point (-1,3) is on the graph of f(x) = ax^2 + 2
Answer:
a = 1
Step-by-step explanation:
Plug in the point into the equation, then solve for a:
f(x) = ax² + 2
3 = a(-1²) + 2
3 = a + 2
1 = a
So, a = 1
The points on a graph are the true values of the graph
The value of a is 1
The equation is given as:
[tex]f(x) = ax^2 + 2[/tex]
At point (-1,3), the equation becomes
[tex]3 = a(-1)^2 + 2[/tex]
Evaluate the exponent
[tex]3 = a(1) + 2[/tex]
This gives
[tex]3 = a + 2[/tex]
Subtract 2 from both sides
[tex]a =1[/tex]
Hence, the value of a is 1
