Answer:
x=12
Step-by-step explanation:
the (8x-17)° and (5x+19)° angles are corresponding angles
since lines are parallel and cut by a transversal, this means that these angles are congruent
to find x:
8x-17=5x+19
3x-17=19
3x=36
x=12

What is the equation of the line that is perpendicular to the line y=3/4x - 6 and passes through the point (-3,5)?
Answers
Answer:
[tex]y=-\frac{4}{3}x+1[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. -1/3 and 3, 1/2 and -2, etc.)1) Determine the slope (m)
[tex]y=\frac{3}{4} x - 6[/tex]
Looking at the given equation, we can identify clearly that [tex]\frac{3}{4}[/tex] is in the place of m, making it the slope of the line. Because perpendicular lines always have slopes that are negative reciprocals, we know that the slope of the line we're solving for will be [tex]-\frac{4}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\frac{4}{3}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-\frac{4}{3}x+b[/tex]
Plug in the given point (-3,5)
[tex]5=-\frac{4}{3}(-3)+b\\5=4+b[/tex]
Subtract 4 from both sides
[tex]5-4=4+b-4\\1=b[/tex]
Therefore, the y-intercept is 1. Plug this back into [tex]y=-\frac{4}{3}x+b[/tex]:
[tex]y=-\frac{4}{3}x+1[/tex]

What is the length of the line?
Choose 1 answer:
Answers
Answer:
√29
Step-by-step explanation:
We can use the pythagorean theorem to find the length of this line. You can draw a vertical line downwards from the higher point and a horizontal line towards the left from the lower point. This will create a right triangle. Wd can count the lengths of the legs, getting 2 and 5. We can substitute these values in the pythagorean theorem:
a^2 + b^2 = c^2
2^2 + 5^2 = c^2
4 + 25 = c^2
c^2 = 29
c = √29
Since c is the hypotenuse and is the same length of the line, the line is √29 units long

Explain how to find the volume of the four ice cubes in the glass below if each ice cube is 2 inches wide. Pls help
Answers
The total volume of the ice cubes is 32 in^3
We know that, for a cube of side length L, the volume is:
V = L^3
So if we know that each of the ice cubes is 2 inches wide, we can see that the side length of each ice cube is 2 inches.
Then we have L = 2in
Then the volume of each ice cube is:
V = (2in)^3 = 8 in^3
And we have four of these, then the total volume is 4 times the volume of a single ice cube.
Total volume = 4*( 8 in^3) = 32 in^3

What is the volume of the prism in cubic inches ?
what is the surface area in square inches ?
Answers
Answer:
Step-by-step explanation:
Volume
V = B * h
B = 1/2 a * b
Solution
Area of Triangles = B = 1/2 * 6 * 8
Area of Triangles = B = 24 square inches
Volume = B * H
Volume = 24 * 12
Volume = 288 cu in
Surface Area
Triangles
Area of one triangle = 24 square inches [ See Above ]
Area of two triangles = 48 square inches
Left Side
Area = L * W
L = 12
W = 8
Area = 12 * 8
Area = 96
Right side
Area = L * W
L = 12
W = 6
Area = 12 * 6
Area = 72
Area Back
L = 12
W = 10
Area = 12 * 10
Area = 120
Total = 120 + 72 + 96 + 48 = 336 square inches
Create an equation which contains the solution (-1,3)
Answers
Answer:
3x + y =0
Step-by-step explanation:
We need to create equation whose solution is (-1,3) . So let another point through which it passes be ( 0,0) .
Since at least two points are required for making a line .Slope :-
=> m = -1-0/3-0
=> m = -1/3
Using point slope form :-
=> ( x - x1) = m( y - y1)
=> ( x - (-1)) = -1/3( y - 3)
=> (x + 1 )3= -y + 3
=> 3x +3 = -y + 3
=> 3x + y = 0
✔️ Checking :-
(-1,3)=> 3(-1) + 3 = 0
=> -3+3=0
=> 0 = 0
• Hence the equation can be 3x + y = 0 .Jorge works at a dairy farm that ships eggs to restaurants. Jorge decides to try new packaging for the eggs to see if it results in fewer broken eggs.

Current packaging: 5, 9, 4, 4, 5, 5, 7, 4 New packaging: 3, 6, 6, 3, 5, 5, 6, 5 The means are 5.375 and 4.875 respectively, for a difference of 0.5.

Answer:
x=11
Step-by-step explanation:
The sum of the angles of a triangle is 180
We know the angle with a box is 90
90 + 5x-2 + 3x+4 = 180
Combine like terms
8x +92 = 180
Subtract 92 from each side
8x+92-92 = 180-29
8x = 88
Divide each side by 8
8x/8 = 88/8
x = 11
