Answer:
y-intercept = -2
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1})[/tex]
y - 4 = 3(x - 2) Now change the equation to slope-intercept form
y - 4 = 3x -6
y = 3x - 2 So m = 3 b = y-intercept = -2
How many moles is 1.46 g of hydrogen gas
The number of moles is 1.4484 moles
What is one mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12
The 6.022 x 10²³ number is known as the number of Avogadro or the constant of Avogadro.
(12 g C = 1 mol C atoms = 6.022 × 10²³ C atoms)
Given data ,
Grams of Hydrogen = 1.46 grams of Hydrogen
Now , 1 g of Hydrogen has 0.99212 mole
So , to calculate the number of moles in 1.46 grams of Hydrogen =
Grams of Hydrogen x 0.99212 mole
The number of moles in 1.46 grams of Hydrogen = 1.46 x 0.99212
= 1.4484 moles
Hence , the number of moles in 1.46g of Hydrogen is 1.4484 moles

The length of a rectangle is 3cm more than its width.If the area of the rectangle is 28cm^2,find the width.
Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm

Find the value of in the triangle shown below.
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)

¿Qué peso transporta una tractomula que lleva 134 bultos de trigo de 62 kilos cada uno, 28 sacos de café de 50 kilos cada uno y 37 bultos de arroz de 75 kilos cada uno?
Answer:
the total weight is 12,483 kilos
Step-by-step explanation:
The computation of the weight is shown below:
Wheat = 134 × 62 = 8308
Coffee = 28 × 50 = 1400
Rice 37 × 75 = 2775
Total weight is
= 8308 + 1400 + 2775
= 12,483 kilos
Hence, the total weight is 12,483 kilos

Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5
3x - 3x + y = 5 - 3x
y = 5 - 3x
--------------------------------------------------------
4x + 2y = 20
4x + 2(5 - 3x) = 20
4x + 2(5) + 2(-3x) = 20
4x + 10 - 6x = 20
10 - 2x = 20
10 - 10 - 2x = 20 - 10
-2x = 10
-2x ÷ -2 = 10 ÷ -2
x = -5
--------------------------------------------------------
y = 5 - 3x
y = 5 - 3(-5)
y = 5 + 15
y = 20

(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
