Use substitution to solve the
following system of equations.
-10x + 2y = 20 AND y = 3x + 2
pls pls help!
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 )

Given m∠A=39° and m∠F=56°, what is m∠C?
Answer:
x=85
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.

What is the y-intercept in this equation?
6x + 3y = 24
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.
Hope this helps!
Doea the equation 6y=18x represent a direct variation? If it does, what is the constant of variation
Answer:
Yes
3
Step-by-step explanation:
a direct variation is written in the form
y = kx
k is a constant which is usually non zero.
6y = k18x
k = 3
An increase in x would lead to an increase in y

Step-by-step explanation:
let's take the ramp, if u draw a diagram 8, 10 and the unknown value makes a right angled triangle
So according to pythogaraos(dnot care the spelling) theorem a square + b square = c square
Now 10 is the hypothenuse, so let's rearrange them as c square - b square = a square
now apply the values, 10 square - 8 square = X square
100 - 64 = X square
36 = X square
now root of 32 is-------

Standard form 3x-- 3y - 12 Slope intercept form
Answer:
Slope - intercept form
y = x - 4
Step-by-step explanation:
Explanation:-
Given standard form
3 x- 3y - 12 = 0
Slope - intercept form
y = m x + c
Given straight line
3 x- 3y - 12 = 0
⇒ 3 x - 3 y = 12
Dividing by '12' on both sides, we get
[tex]\frac{3x}{12}- \frac{3y}{12} = 1[/tex]
[tex]\frac{x}{4}- \frac{y}{4} = 1[/tex]
x - y = 4
Final answer:-
Slope - intercept form
y = x - 4

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).

Answer:
YES
Step-by-step explanation:
Which of the following is the point-slope form of the equation of the line with slope 4
that crosses the point (1, 3)?
Oy-1= 4(x – 3)
