what is it called when two lines intersect
Answer:
The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.

I can't make a good explanation, so here's a graph.
Also, this wouldn't be a proportional relationship because of exponents on the last term.
This is really a parabola.
Find the slope of the line
8 – 7x = 4y
Step-by-step explanation:
y = mx + c
8 - 7x = 4y
4y = 8 - 7x
y = (8 - 7x)/4
= 2 - 7/4x
y = -7/4x + 2
Slope = m = -7/4
Answer:
slope = - [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8 - 7x = 4y, that is
4y = - 7x + 8 ( divide all terms by 4 )
y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{7}{4}[/tex]

Her budget is $65 a month. To find out how many gigabytes of data she could use if she chose this plan, she writes C(x)=65 and solves for x. What value of x makes this equation true?
Remember the function is C(x)=30x+5.
Answer:
Consider all the info you are given:
The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.
You're given C(x) = 30x + 50, the monthly cost of the plan
'x' is the GB of data used OVER the allowance (2GB.)
They put over in italics to give you a hint to the solution.
(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26
The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)
(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)
So you the solve for x by setting C(x) = 50
30x + 5 = 50
30x = 50 - 5 = 45
x = 45/30
x = 1.5
Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.
Hope this helps...
Which best describes the figure that is represented by the following coordinates?
A(-4, 3), B (2,3), (3, -1) and D(-5, -1)
a rhombus

Answer:
a rhombus that is the answer
The best describes the figure that is represented by the following coordinates A(-4, 3), B (2,3), (3, -1), and D(-5, -1) will be a rhombus.
What is a rhombus?Its a parallelogram but all sides of the same length.
A rhombus is a parallelogram whose all sides are of equal lengths.
Its diagonals are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).
Its vertex angles are bisected by its diagonals.
The triangles on either side of the diagonals are isosceles and congruent.
The best describes the figure that is represented by the following coordinates A(-4, 3), B (2,3), (3, -1), and D(-5, -1) will be a rhombus.

[tex]\frac{n}{7}[/tex] - 12 = 5n + 5
I need to show my work, please.
Answer:
n= -3.5
Step-by-step explanation:
n/7 - 12 = 5n +5
+12 +12
n/7 = 5n+17
*7 *7
n = (5n+17)*7
n = 35n + 119
-35n -35n
-34n = 119
/-34 /-34
n = -3.5

Solve for the last missing side any way you'd like.
55°
10
35°
8.2
Answer:
12.2
Step-by-step explanation:
Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)
C + 90° = 180°
C = 180° - 90°
C = 90°
Let c be the last side
Using the sine rule a/sinA = b/sinB = c/sinC
Using any of the other two sides,
10/sin55° = c/sin90°
c = 10/sin55° × sin90°
c = 10/0.8192 × 1
c = 12.21
c ≅ 12.2

It is a right triangle. The distance is the hypotenuse of the triangle.
Use the Pythagorean theorem:
Distance = sqrt(3^2 + 2^2)
Distance = sqrt( 9 + 4)
Distance = sqrt(13) (exact distance)
As a decimal sqrt(13) = 3.60555

You set up a hot chocolate stand at a football game. The cost of your supplies is $75. You charge $0.50 for each cup of hot chocolate. Write a function that represents the profit P for selling c cups of hot chocolate.
Answer:
P = 0.5c - 75
Step-by-step explanation:
Profit is = selling price. - cost price
Cost price is the amount the supplies were bought = $75
The cost of c cups at $0.5 per cup will be
0.5 * c = $0.5c
The profit here is thus;
P = 0.5c - 75

Sara is building a triangular pen for her pet rabbit. If two of the sides measure 8 feet and 15 feet, the length of the third side could be
1) 13 ft
2) 7 ft
3) 3 ft
4) 23 ft
Answer:
1) 13 ft
Step-by-step explanation:
1) 13+8=21 which is greater than 15. Would be a triangle.
2) 7+8=15 This would be a single line, not a triangle.
3) 3+8<15 This would be a single line, not a triangle.
2) 15+8=23 This would be a single line, not a triangle.
so for translation when it says to move up 6 how do I solve that (ex. -6, -10)

when i solved i got -17/-1, but my calculator says it's 17! i tried searching and it said to divide the fraction to get 17, but why do i have to divide? can someone please help me, thank u!
Answer:
-17/-1 and 17 are the same so you are correct!
Step-by-step explanation:
in the fraction, -17/-1, you want to get rid of the negatives. in order to do that, you have to get rid of them on both the numerator and denominator! so the new fraction would be 17/1, and that would be simplified to just 17! so you are correct, i hope this helps!
Answer:
yes your cauculators correct, it is 17
