Juan thinks that the graph of 6y + 12x = 4 is a line. a. Solve Juan’s equation for y.
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Juan thinks that the graph of 6y + 12x = 4 is a line.
Solve the equation of the line for y, then we have
6y + 12x = 4
6y = 4 - 12x
y = 4/6 - (12/6)x
y = 2/3 - 2x
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

Triangle ΔGHI with m∠G = 5°, m∠H = 75° and m∠I = 100°, is reflected across the y-axis to obtain ΔKLM. What is the measure, in degrees, of ∠L?
Answer:
[tex]\angle L = 100^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle G = 5^{\circ}[/tex]
[tex]\angle H = 75^{\circ}[/tex]
[tex]\angle L = 100^{\circ}[/tex]
Required
Determine the measure of L after reflection across x-axis
When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.
In other words, the measures of the angle will not change.
Hence:

Answer:
Option B
Step-by-step explanation:
Given expression is,
(x² - 18x + 180)
Which is in the form of (ax² + bx + c)
To factorize the given expression, we will split b in two parts [tex]b_1[/tex] and [tex]b_2[/tex] so that,
[tex]b=b_1+b_2[/tex]
And [tex]c=b_1\times b_2[/tex]
If b = 18,
[tex]b_1=10[/tex] and [tex]b_2=8[/tex]
c = 10 × 8 = 80
Therefore, (x² - 18x + 180) = x² - 10x - 8x + 80
= x(x - 10) - 8(x - 10)
= (x - 8)(x - 10)
Option B is the correct option.

Mónica ha comprado un CD el dependiente le dice que ha descontado el 20% de su valor siendo ese descuento de $20 cuánto costaba inicialmente el CD
Answer:
El CD costaba $100 inicialmente.
Step-by-step explanation:
Dado que la información indica que el porcentaje de descuento es 20% y ese descuento tiene un valor de $20, puedes usar una regla de tres para encontrar el valor que representa el 100% que sería el valor inicial del CD dado que el 20% del valor es igual a $20:
20% → 20
100% → x
x=(100*20)/20=100
De acuerdo a esto, la respuesta es que el CD costaba $100 inicialmente.

Ronald is buying a rectangular chest to store his carpentry tools. The height of the chest, in feet, is represented by the function H(x) = x+6.
The area of the base of the chest, in square feet, is represented by the function A(x)= 20 square root x/ 3. In both functions, x represents the width of the
chest in feet.
To find a function that represents the volume of the chest, Ronald should ? Functions H(x) and A(x)

Answer:
Multiply ; 40
Step-by-step explanation:
Given that :
Height, H of rectangular chest = H(x) = x+6.
Area of rectangular chest, A(x) = 20√x /3
Recall; Volume of chest = Base area * Height
(X + 6) * 20√x /3
(20x√x /3 ) + (20 * 6√x/3)
(20x√x /3 ) + (20 * 2 * 3√x/3)
(20x√x/3) + 40√x
The correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.
What is the function about?Based on the fact that we have been given the Height =H of rectangular chest to be:
= H(x) = x+6.
When the Area of rectangular chest:
A(x) = 20√x /3
Note that: Volume of chest = Base area x Height
Therefore:
(X + 6) * 20√x /3
(20x√x /3 ) + (20 * 6√x/3)
(20x√x /3 ) + (20 * 2 * 3√x/3)
(20x√x/3) + 40√x
Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

Radius of the circle is 20cm. there are two chords of lengths.
32cm, what will be the dis-
tance of these chords from
the centre of the circle?
9514 1404 393
Answer:
12 cm
Step-by-step explanation:
The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.
The chords are 12 cm from the center.
_____
You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...
c² + d² = r²
16² + d² = 20²
d² = 400 -256 = 144
d = √144 = 12 . . . . . cm
Cameron & Brett are trying to sell upper & lower level tickets to two Diamondbacks game to raise money for their club baseball team. They sold 5 lower level & 9 upper level tickets to the first game for a total of $303. They sold 8 lower level & 10 upper level tickets to the second game for a total of $410. How much money did the people pay for lower level & upper level tickets to go to a Diamondbacks game?
Answer:
30 Lower level tickets
17 upper level tickets
Step-by-step explanation:
Let:
Lower level tickets = l
Upper level tickets = u
5l + 9u = 303 - - - (1)
8l + 10u = 410 - - - - - (2)
Multiply (1) by 8 and (2) by 5
40l + 72u = 2424 - - - (3)
40l + 50u = 2050 - - - (4)
Subtract (3) from (4)
22u = 374
u = 374 / 22
u = 17
Put u = 17 in (1)
40l + 72(17) = 2424
40l + 1224 = 2424
40l = 2424 - 1224
40l = 1200
l = 1200 / 40
l = 30
30 Lower level tickets
17 upper level tickets

y = 34√2
y = 34√3
z = 17
z = 34
z = 17√2
z = 34√3
Answer:
Step-by-step explanation:
The first triangle right isosceles. The sides opposite the 45° angles are the same length.
x = 13
By the Pythagorean Theorem, y = 13√2
:::::
Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.
x = 6
y = 3√3
:::::
The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.
x = 17√3
The other triangle is right isosceles.
z = 34
y = 34√2
