solve this system of liner equations:
4x - 2y = 8 y= 3/2x - 2
step 1: plot the x-intercept of the first equation
Answers
x = 4 , y = 4
Step-by-step explanation:
Solve the following system:
{4 x - 2 y = 8 | (equation 1)
y = (3 x)/2 - 2 | (equation 2)
Express the system in standard form:
{4 x - 2 y = 8 | (equation 1)
-(3 x)/2 + y = -2 | (equation 2)
Add 3/8 × (equation 1) to equation 2:
{4 x - 2 y = 8 | (equation 1)
0 x+y/4 = 1 | (equation 2)
Divide equation 1 by 2:
{2 x - y = 4 | (equation 1)
0 x+y/4 = 1 | (equation 2)
Multiply equation 2 by 4:
{2 x - y = 4 | (equation 1)
0 x+y = 4 | (equation 2)
Add equation 2 to equation 1:
{2 x+0 y = 8 | (equation 1)
0 x+y = 4 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 4 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = 4 , y = 4

C
Step-by-step explanation:
Since there are two arcs and they both make up a circle, and a circle has 360 degrees.
NPL+NL=360
The measure of NPL is twice the measure of NL so
it now
2NL=NPL
Substitute that in the equation
2NL+NL=360

NL=120
Since NL subtends NML they are equal so NML=120

Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long is the diagonal of the ramp?
Answers
Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft

To measure the width of a river, a ranger sights a tree across a river is about 60 degrees north of east. On the map, her position is marked A. She then walks along the river to position B and sights the same tree at 40 degrees north of west. If each unit on the map is 1 mile, about how many miles from her current position is the tee?
Answers
Answer:
35 miles I'm not sure I think my phone is glitching out on the question because It is in a weird format
The approximate distance from the ranger's current position to the tree is 0.652 miles.
To solve this problem, we can use trigonometry and create a diagram based on the given information.
Let's assume the ranger's starting position (marked A) is the origin (0,0) on a coordinate plane, and she walks along the river to position B. We need to find the distance between the ranger's current position and the tree.
Based on the information provided:
The tree is sighted about 60 degrees north of east from position A.
The tree is sighted at 40 degrees north of west from position B.
Now, let's calculate the coordinates of position B. Since each unit on the map is 1 mile, we can assign coordinates (x, y) to position B.
At position B, we can break down the distance into the horizontal and vertical components:
The horizontal distance from A to B is the same as the horizontal distance from B to the tree.
The vertical distance from A to B is the same as the vertical distance from B to the tree.
Let's denote the horizontal distance as d h and the vertical distance as d v.
From position A, we have:
Horizontal component: d h = d * cos(60°)
Vertical component: d v = d * sin(60°)
From position B, we have:
Horizontal component: d h = d * cos(40°)
Vertical component: d v = d * sin(40°)
Since both d h and d v are the same at position B, we can set up the following equation:
d * cos(40°) = d * cos(60°)
Simplifying the equation, we have:
cos(40°) = cos(60°)
To solve for d, we can divide both sides by cos(40°):
d = cos(60°) / cos(40°)
Using a calculator or trigonometric table, we can find the values of cos(60°) and cos(40°):
cos(60°) ≈ 0.5
cos(40°) ≈ 0.766
Substituting these values:
d ≈ 0.5 / 0.766
Calculating the result:
d ≈ 0.652
Therefore, the approximate distance from the ranger's current position to the tree is 0.652 miles.

Answer:
P(vowel) = [tex]\frac{1}{4}[/tex]
Choosing one letter at random is a simple event.
Step-by-step explanation:
P(vowel) = [tex]\frac{1}{4}[/tex]
This is because there are 2 vowels so the probability [tex]\frac{2}{8}[/tex] is which can be simplified to [tex]\frac{1}{4}[/tex] .
Moreover, Choosing one letter at random is a simple event.
The definition of a simple event is one that can only happen in one way, or in other words, it has a single outcome.
Malik's probability of drawing one letter at random is 1/4.
Probability calculation:P (vowel) = [tex]\bold{ \frac{1}{4}}[/tex] It's good to select one letter at random.
