If f(x) = -3x + 1, find x if f(x) = -3.​

Answer: I think it's either C or A but, my gut is saying A :)

The two lines have the same slope and different y-intercepts, thus, the lines are parallel.

Here we want to find the relation between the two lines:

8x = 3y + 3

-24x + 9y = 3

First, we need to write these two as lines in the slope-intercept form. We will get:

3y = 8x - 3

y = (8/3)*x - 3/3

y = (8/3)*x - 1

And the other one:

9y = 3 + 24x

y = (3/9) + (24/9)*x

y = (1/3) + (8/3)*x

So, we can see that both lines have the same slope (and different y-intercept), thus, the lines are parallel lines.

Answer:

c = 26 cm

Step-by-step explanation:

using the Pythagorean theorem:

10² + 24² = c²

c² = 100 + 576  = 676

c = 26 cm

Therefore, the missing side of the triangle is 5.

To determine the missing side of a triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, if one side of the triangle is 12 and the other side is 13, we can label the missing side as x. Using the Pythagorean theorem, we have:

\(x² = 13² - 12²

x² = 169 - 144

x² = 25\)

Taking the square root of both sides, we find:

\(x = √25

x = 5\)

Answer:

0.75m

Step-by-step explanation:

The volume of a prism is:

the area of the cross section × length

In this case the cross section is the circle so the formula is

v = πr²h

volume = 21m³

height or length = 12m

Sub in the values:

21 = πr² × 12

1.75 = πr² (I divided both sides by 12)

0.5570423008 = r² (I divided both sides by π)

r = 0.74635... (I square rooted both sides)

r ≈ 0.75m (to 2 d.p)

Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the area of circle using the formula :

A = π × r²

A = π × 3²

A = 9π

Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :

A = (θ/360) × π × r²

A = (60/360) × π × 3²

A = 1.5π

Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :

A = (9π × 2) - (1.5π × 2)

A = 18π - 3π

A = 15π

Answer:

A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla

entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100

en mi primera ecuación seria: 4X + 3Y = 14.100

ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla

en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:

primera ecuación: 4X + 3Y = 14.100

segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1

al sumarlas obtengo como resultado: -5X = -12

resolviendo esa ecuacion obtengo que X=  

X=2.4

luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100

reemplazando seria: 4 x (2.4) + 3Y =14.100

9.6 + 3Y = 14.1000

3Y= 14.100 - 9.6

Y=  

Y=1.5

entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

Step-by-step explanation:

The negation of a statement s is called "not s." Hence, the statement "not s" is the negation of s.

The statement "not s" is called the negation of s, and it represents the opposite meaning of the original statement s. If s is true, then "not s" is false, and if s is false, then "not s" is true.

The negation of a statement is an important concept in logic, and it is used to prove or disprove the original statement by contradiction. By assuming the negation of the statement, we can try to show that it leads to a contradiction or an absurdity, which would imply that the original statement must be true.

In mathematics and other fields, the ability to negate a statement is a crucial tool for constructing proofs and solving problems.

The use of negation allows us to reason about the relationships between different statements and to establish the validity of arguments and claims.

The limit - A. lim 3x = 21, x → 7. The correct choice is A.

The limit of 3x as x approaches 7 can be evaluated by substituting the value 7 into the expression 3x:

lim 3x = 3(7) = 21.

x → 7

Therefore, the correct choice is:

A. lim 3x = 21.

x → 7

To elaborate further, when we evaluate the limit of 3x as x approaches 7, we substitute the value of 7 into the expression 3x. This gives us:

lim (3x) = 3(7) = 21

This means that as x gets arbitrarily close to 7 (but not equal to 7), the value of 3x approaches 21. In other words, as we consider x values approaching 7 from both the left and the right sides, the corresponding values of 3x approach 21.

Therefore, the limit exists and we can determine its value (which is 21), we can conclude that the limit of 3x as x approaches 7 is indeed 21 (Choice A).

The slope of the line in the simplest form is 1 / 2.

The slope of a line is the change in the dependent variable with respect to the change in the independent variable.

The slope is rise over run.

The slope of the line can be found as follows:

m = slope = y₂ - y₁ / x₂ - x₁

Therefore, using (7, 0) and (3, -2)

Hence,

x₁ = 7

x₂ = 3

y₁ = 0

y₂ = -2

Therefore,

slope = - 2 - 0 / 3 - 7

slope = - 2 / -4

slope = 1 / 2

Explanation:

The angles SPT and TPU marked in red are congruent. They are congruent because of the similar arc markings.

Those angles add to the other angles to form a full 360 degree circle.

Let x be the measure of angle SPT and angle TPU.

86 + 154 + 60 + x + x = 360

300 + 2x = 360

2x = 360-300

2x = 60

x = 60/2

x = 30

Each red angle is 30 degrees.

Then,

angle SPQ = (angle SPT) + (angle TPU) + (angle UPQ)

angle SPQ = (30) + (30) + (86)

angle SPQ = 146 degrees

--------------

Another approach:

Notice that angles QPR and RPS add to 154+60 = 214 degrees, which is the piece just next to angle SPQ. Subtract from 360 to get:

360 - 214 = 146 degrees

Three 2-dimensional vectors that do not span \(R^2\) are (1, 0), (0, 1), and

(1, 1).

These vectors do not span \(R^2\) because they are all lying on a single line and cannot fill the entire plane.

A set of vectors spans a space if every vector in that space can be represented as a linear combination of the set of vectors. In this case, since these three vectors lie on the same line, any vector that is not on that line cannot be represented as a linear combination of these three vectors. Thus, these three do not span \(R^2\).

A dimensional vector, also known as a vector, is a mathematical object that represents a quantity with both a magnitude (or length) and a direction. It can be thought of as an arrow in space, where the length of the arrow represents the magnitude of the vector and the direction of the arrow represents the direction of the vector.
