What the value of x.please

Answers

Answer 1

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name, or symbol. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

i think the x doesn’t have a value but if it’s also then it means one or you can put 1x in front of it

Answers

Answer: Y=-5x+3

Step-by-step explanation:

first slope= 0 on the x axis so -2-3=-5

to get 3 you can do 4-1=3 or 7-4 or even 1-(-2)!

Correct answer: [tex]y = 3x -5[/tex]

You don't have to use the whole table in order to find equation. You can use just two points on the table to start.

In order to find the slope, the formula for that is: [tex]\frac{y_{2}-y_{1}}{x_{2} - x_{1}}[/tex]. So, we can start with points (1, -2) and (2, 1). Label (1, -2) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex]; label (2, 1) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now we can plug the numbers into the formula.

[tex]\frac{1-(-2)}{2 - 1}[/tex] → [tex]\frac{3}{1}[/tex] → [tex]3[/tex] is the slope.

To find the y-intercept, substitute (1, -2) into [tex]y = 3x + b[/tex].

[tex](-2) = 3(1) + b[/tex]

[tex]-2 = 3 + b[/tex]

[tex]-3[/tex]   [tex]-3[/tex]

________

[tex]b = -5[/tex] is the y-intercept.

Thus, the slope-intercept equation is [tex]y = 3x -5[/tex]. Hope this helps :) Let me know if you have any other questions related to this problem!

Answers

Answer:

D. b = 3

Step-by-step explanation:

Given the following data;

Points on x-axis (x1, x2) = 10, 12

Points on y-axis (y1, y2) = 23, 27

First of all, we would determine the slope.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {27 - 23}{12 - 10} [/tex]

[tex] Slope, m = \frac {4}{2} [/tex]

Slope, m = 2

The equation of straight line is y = mx + b

Where;

m is the slope.

x and y are the points

b is the intercept.

To find the intercept, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 23 = 2(x - 10)

y - 23 = 2x - 20

y = 2x - 20 + 23

y = 2x + 3 = mx + b

Therefore, intercept, b = 3

a shipping company sells large boxes and small boxes. The dimensions of the large box are 3 times the dimensions of the small box.
How does the volume of the large box compare to the volume of the small box?
a) the volume of the large box is 3 times the volume of the small box
b) 6 times
c) 9 times
d) 27 times

Answers

Answer:

d) 27 times

Step-by-step explanation:

Let l,w, and h represent the length, width and height of the small box.

Therefore, 3l,3w, and 3h are the dimensions of the large box.

The volume of a rectangular prism, such as a box, is the product of its length, width and height

Volume of small box = l*w*h = lwh

Volume of large  box = 3l*3w*3h = 27lwh

So we can see that the volume of the large box is 27 times larger.

If the original cost of the dress was c dollars, which of the following expressions represents what Sandra would pay, in dollars, for the dress?​

Answers

0.25c - that’s 25% off the cost (c) of the dress

Sandra would pay in dollars for the dress is 0.76 c

What is discount ?

discount. if telling in the simple sentence discount means something which u get at lower price by its original price

According to the question,

c×(1 - 5%) × (1 - 20%)

=c×(1 - 0.05) × (1 - .20)

=c × 0.95 × 0.8

=0.76 c

Hence, Sandra would pay in dollars for the dress is 0.76 c

Answer:

Use the law of cosines to find c:

c = [tex]\sqrt{a^2 + b^2 - 2ab*cos C}[/tex]c = [tex]\sqrt{2^2+6^2-2*2*6*cos 95}[/tex] = [tex]\sqrt{42.09}[/tex] = 6.49

Use the low of sines to find one of the missing angles:

sin A / 2 = sin 95° / 6.49A = arcsin (2 sin 95° / 6.49)A = 17.9°

Find the missing angle:

B = 180° - (A + C)B = 180° - (95° + 17.9°) = 67.1°

Answer:

c ≈ 6.49

A ≈ 17.9°

B ≈ 67.1°

Step-by-step explanation:

To find the length of side c, use the Cosine rule.

Cosine rule

[tex]\sf c^2=a^2+b^2-2ab \cos C[/tex]

(where a, b and c are the sides and C is the angle opposite side c)

From inspection of the given triangle:

a = 2b = 6C = 95°

Substitute the given values into the formula and solve for c:

[tex]\implies \sf c^2=2^2+6^2-2(2)(6) \cos 95^{\circ}[/tex]

[tex]\implies \sf c^2=4+36-24 \cos 95^{\circ}[/tex]

[tex]\implies \sf c=\sqrt{40-24 \cos 95^{\circ}}[/tex]

[tex]\implies \sf c=6.49\:\:(2\:d.p.)[/tex]

To find angles A and B, use the Sine Rule.

Sine Rule

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

From inspection of the given triangle:

a = 2b = 6[tex]\sf c=\sqrt{40-24 \cos 95^{\circ}}[/tex]C = 95°

Substitute the given values into the formula:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

Solving for A:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf A=\sin^{-1}\left(\dfrac{2\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]

[tex]\implies \sf A=17.9^{\circ}\:\:(1\:d.p.)[/tex]

Solving for B:

[tex]\implies \sf \dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf B=\sin^{-1}\left(\dfrac{6\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]
