Answer:
the rate of change from 4 to 8 is 4
Step-by-step explanation:
you can find this by subtracting the first number from the secone number and if the two numbers were in a diffrent order being 8 and 4 the answer would still be 4 because when you subtract 8 from 4 you ger-4 but with rate of change you always use the absolute value

Answer:
Step-by-step explanation:
4 (x + 2) =30
4x + 8 = 30
4x = 30 - 8
4x = 22
x = 22 : 4
x = 5.5
check
(5.5 + 2) * 4 = 30
the answer is good
Answer:
the cost of each sandwich is 5.5
Step-by-step explanation:
we have,
4(x+2) = 30
we know a(b+c) = ab+ac
so, when we open the bracket we get,
4(x+2) = 4x+4*2 which is equal to 4x+8
so, 4x+8 = 30
=> 4x = 30 - 8 [transposing method]
=> 4x = 22
=> x = 22/4
=> x = 5.5

[tex]5(4x - 4) = 5(3x + 3) \\ \cancel5(4x - 4) = \cancel5(3x + 3) \\ (4x - 4) = (3x + 3) \\ 4x - 3x = 4 + 3 \\ x = 7[/tex]
Verification:-Put the value of X in equation:-
LHS:-
[tex]5(4x - 4) = 5(4(7) - 4) \\ 5(28 - 4) \\ 5(24) = 120[/tex]

1. Jessica drove 345 miles on

about how many miles did she

Answer:
To the nearest 100 miles, Jessica drove about 300 miles since we haven't reached 350 miles. If we have a number that is greater than 350 miles than we would've rounded it up to 400 but since ours is less than that we round down to the nearest hundred which is 300 miles.

A hot air balloon holds 1,592 cubic meters of helium. the density of helium is 0.1785 kilograms per cubic meter. how many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram? 432.3 kg 284.2 kg 2,043.7 kg 5,435.3 kg
By taking the product between density and volume we will see that the mass is 284.2 kg
How to find the mass of helium?Remember that density is the quotient between mass and volume, then:
mass = density*volume.
Here we know that:
volume = 1,592 m³density = 0.1785 kg/m³Taking the product of these two we get:
mass = (1,592 m³)*(0.1785 kg/m³) = 284.2 kg
So the correct option is the second one.

A) The function f is defined by : f(x) = x2+ax+b
a and b are constants.
It is known that: f(0) = 7 and f(-2) = 17
Find the values of a and b.
B) Use the values of a and b to solve this equation: f(x) = 35
x = __ or x = __?
Answer:
A. a = -3 and b = 7.
B. x = -4 or x = 7.
Step-by-step explanation:
A)
f(0) = 0^2 + a(0) + b = 7
So b = 7.
f(-2) = (-2)^2- 2a + 7 = 17
4 - 2a = 17 - 7
4 - 2a = 10
-2a = 10 - 4 = 6
-2a = 6/-2
a = -3.
B)
Substituting a = -3 and b = 7 we get:-
x^2 - 3x + 7 = 35
x^2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0 or x + 4 = 0
x = -4 or x = 7.

The height is ABThe radius is CBThe diameter is CDThe vertex is AWhat is a cone ?A cone can be regarded as a three-dimensional shape which has a vertex at the top of it.
Considering a cone as described in the question, we could see that the distance from point A to B will gives us the height which is the vertical length.
Therefore, Vertex is at the top of the cone which is point A.

The first four terms of a sequence are shown on the graph below.
What can be concluded about the sequence?
The common ratio of the sequence is 2.
The common difference of the sequence is 2.
The next term of the sequence is represented by the point (5, 64).
The next term of the sequence is represented by the point (5, –64).
Answer:
The next term of the sequence is represented by the point (5, –64)
Step-by-step explanation:
From inspection of the graph, the first four terms of the sequence are:
(1, -4)(2, 8)(3, -16)(4, 32)Each x-value increases by 1 for each consecutive term.
Each y-value is the previous y-value multiplied by -2.
Therefore, it is a geometric sequence with a common ratio of -2.
Following the above rule, if the last term in the sequence is (4, 32), then the next term in the sequence will be:
x = 4 + 1 = 5y = 32 × -2 = -64So, the next term of the sequence is represented by the point (5, –64)

Titanium 0.161
Zinc 0.258
Iron 0.284
Silver 0.379
Using the table, what is the element?
A.Zinc
B.Silver
C.Iron
D.Titanium
The density become by the elemental composition of the person has will be 0.258 and hence, option (A) will be correct.
What is the density?In science, density is defined as the ratio of an object's mass to volume. Technical and statistical density assessments are done using a technique. The theory is applicable to the laws of nature in sciences like physics, where the emphasis is on things and matter.
Because density affects so many aspects of life, comprehending it is crucial. Which cells will float high in the atmosphere and which will sink lower depends on density, according to physics.
Given that the element has
Volume = 16 cubic inch
weight = 4.13 pound
Since density = weight / volume
density = 4.13/16
density = 0.258 which is matching through option (A) hence it will be correct.

Answer:
1728 in³
Step-by-step explanation:
Given that,
→ Area = 144 sq in
Then the length will be,
→ a² = 144
→ a = √144
→ [ a = 12 ]
Formula we use,
→ V = a³
Now required volume will be,
→ a³ = 12³
→ 12 × 12 × 12
→ 1728 in³
Hence, the volume is 1728 in³.
