-10x + 2y = 20 AND y = 3x + 2
pls pls help!
Answers
Answer:
(- 4, - 10 )
Step-by-step explanation:
Given the 2 equations
- 10x + 2y = 20 → (1)
y = 3x + 2 → (2)
Substitute y 3x + 2 into (1)
- 10x + 2(3x + 2) = 20 ← distribute parenthesis and simplify left side
- 10x + 6x + 4 = 20
- 4x + 4 = 20 ( subtract 4 from both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into (2) for corresponding value of y
y = 3(- 4) + 2 = - 12 + 2 = - 10
solution is (- 4, - 10 )

Step-by-step explanation:
let's angle c be x
39+56+x=180
95+x=180
x=180-95
x=85
Answer:
85 degrees
Step-by-step explanation:
In similar triangles, corresponding angles are congruent, or have the same measure.
Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.
A+b+c=180
39+56+c=180
c=85 degrees.

A meal costs $30 before tax and tip. There is a 7% sales tax. After the tax, a 20% tip is added. What is the total after tax and tip?
Answers
Answer:
The total is $38.1
Step-by-step explanation:
The tax is $2.1, The tip is $6.
Percentage is the part of the whole expressed in the fraction of hundred.
The total cost of the meal after the tip and tax is $38.1.
What is percentage of a number?
Percentage of a number or ratio expressed in the form of fraction of hundred.
Given information-
The total cost of meal before tax and tip is $30.
The total sales tax is 7%.
The tip added to the cost of meal is 20%.
As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,
[tex]s_t=30\times\dfrac{7}{100} \\s_t=2.1[/tex]
Thus the amount of sales tax is 2.1.
As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,
[tex]s_t=30\times\dfrac{20}{100} \\s_t=6.00[/tex]
The amount of the tip of the meal after the tax is $6.00.
The cost of meal after the tip and tax is,
[tex]C=30+2.1+6\\C=38.1[/tex]
Hence the total cost of the meal after the tip and tax is $38.1.

The derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).
What is trigonometric identity?The trigonometric identities is the relationship between the different trigonometric ratios.
These trigonometric identities are the basic formulae that are true for all the values of the reference angle.
For the given situation, the derivation for the tangent sum identity is given in the table below.
The derivation follows the steps,
[tex]\dfrac{sin (x+y)}{cos (x +y)}[/tex]
we know that,
sin (x + y) = sin x cos y + cos x sin y
cos (x + y) = cos x cos y - sin x sin y
Substitute;
[tex]\dfrac{sin x cos y + cos x sin y}{cos x cos y - sin x sin y}[/tex]
Divide each term by cos x cos y
[tex]\dfrac{\dfrac{sin x cos y}{cos x cos y} + \dfrac{cos x sin y}{cos x cos y} }{\dfrac{cos x cos y}{cos x cos y} - \dfrac{sin x sin y}{cos x cos y} }[/tex]
Now, [tex]\dfrac{tan x + tan y}{1 - tan x tan y}[/tex]
Hence we can conclude that the derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).

Step-by-step explanation:
We need to find the hypotenuse of the blue triangle, as stated in the hint. We know the sides of the base measure 8 x 15 respectively so let's use Pythagorean Theorem;
8^2 + 15^2 = (hyp.)^2,
hyp = √8^2 + 15^2 = √64 + 225 = √289 = 17
Now the height of the yellow triangle is 10 inches. The hypotenuse of the blue triangle is now the base of the yellow triangle. The dimensions are 10 x 17 respectively so we can determine it's hypotenuse;
hyp (yellow triangle) = √17^2 + 10^2
= √289 + 100
= √389 ≈ 19.7 in.
What is the y-intercept in this equation?
6x + 3y = 24
Answers
Answer: y=−2x+8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Let's rewrite this in slope intercept form, and isolate y on the left side. First, subtract 6x from both sides:
3y = 24 - 6x
Then divide both sides by 3:
y = -2x + 8
Now that it's in y = mx+b form, we can see that the slope is -2, and the y intercept is 8.
