Answer:
The slope is -2 !!
Answer:
It has no slope
Step-by-step explanation:
It has no slope. Slope equations are in the form y=mx + b. The "m" is the slope and the "b" is the y-intercept (the y-intercept is the point on the y-axis that the line goes through.). So since your equation is y=-4, there is not slope given, only the y-intercept which means it is a flat line that goes through -4 on the y-axis. I hope that helped.
Write an equation of a line that is (a) parallel to the given line and (b)
perpendicular to the given line.
can you answer 7 too ?
Answer:
for question 7 : I think it is no
Step-by-step explanation:
if you plot the points on a quick rough sketch you will find that none of the coordinates are on the same line (which they would have to be for a straight line). No points in those 3 coordinates are the same so the there cannot be two points on the same x or y coordiante therefore there is no right-angles triangle.
If you plot the points roughly there will not be two perpendicular lines so there is no right-angles triangle.
sorry I realise this is confusing :(
Also for Question 5:
Parallel should be anything y= for example, y=6
Perpendicular should be anything x= for example x=6 as y=7 is a horizontal line and x=6 is a vertical line. Y=6 would be parallel because y=(any number with no gradient e.g. 1,2,3,4,etc.) is horizontal.

answer as m2
Answer:
Area = 76[tex]m^{2}[/tex]
Step-by-step explanation:
you can cut into two rectangles
first one:
top and bottom sides = 4m
two sides = 9m
Area = b*h = 9m * 4m = 36 [tex]m^{2}[/tex]
second one
top and bottom sides = 8m
two sides = 14m - 9m = 5m
Area = b*h = 8m * 5m = 40[tex]m^{2}[/tex]
Now add both rectangle areas for the total shaded Area = 36 + 40 = 76[tex]m^{2}[/tex]

The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is . The solution to the inequality is . Sal's mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.
Question:
Sal is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month for unlimited usage. The second phone costs $150 and $51 per month for unlimited usage.
The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is .
The solution to the inequality is .
Sal’s mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.
Answer:
a. [tex]150 + 51x < 100 + 55x[/tex]
b. [tex]x > 12.5[/tex]
c. At least 13 months
Step-by-step explanation:
Given
First Phone;
[tex]Cost = \$100[/tex]
[tex]Additional = \$55[/tex] (monthly)
Second Phone;
[tex]Cost = \$150[/tex]
[tex]Additional = \$51[/tex] (monthly)
Solving (a): The inequality
Represent the number of months with x
The first phone is expressed as:
[tex]100 + 55x[/tex]
The second phone is expressed as:
[tex]150 + 51x[/tex]
For the second to be less expensive that the first, the inequality is:
[tex]150 + 51x < 100 + 55x[/tex]
Solving (b): Inequality Solution
[tex]150 + 51x < 100 + 55x[/tex]
Collect Like Terms
[tex]51x-55x<100 - 150[/tex]
[tex]-4x<-50[/tex]
Solve for x
[tex]x > -50/-4[/tex]
[tex]x > 12.5[/tex]
Solving (c): Interpret the solution in (b)
[tex]x > 12.5[/tex] implies 13, 14, 15....
Hence, She'll keep the second phone for a period of at least 13 months

(-2,0) is a solution of the equation 2x - 3y = 6
Is that true or false
Answer: False
Step-by-step explanation:
To see if (-2,0) is a solution to the given equation, we can plug in the point and solve. If we get the same answer, then it is a solution.
2(-2)-3(0)=6 [multiply]
-4-0=6 [subtract]
-4≠6
Now, the doesn't equal sign tells us that -4 is not equal to 6. This means the given point is not a solution to the equation, making it false.

Convert the equations in #4-6 to standard form.
#4. y = 9/7x + 1/7
#5. y = -6/5x - 3
#6. y = 1/3x - 2
Answer:
Ok im using a standered form calculator:
1. 9/7x + 1/7 = -8
2. y = -6/5x - 3 = -11

Pythagorean Theorem: a² + b² = c²Step-by-step explanation:
Step 1: Define
We are given a right triangle. We can use Pythagorean Theorem.
a = 19
b = x
c = 21
Step 2: Find x
Substitute: 19² + x² = 21²Isolate x term: x² = 21² - 19²Evaluate: x² = 441 - 361Subtract: x² = 80Isolate x: x = √80Simplify: x = 4√5And we have our final answer!

Find three consecutive even integers such that the sum of the first and the third is 128.
9514 1404 393
Answer:
62, 64, 66
Step-by-step explanation:
I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...
(x -2) +(x +2) = 128
2x = 128 . . . . . collect terms
x = 64 . . . . . . . divide by 2
The middle integer is 64, so the three even integers are 62, 64, 66.

Which ordered pair is the solution to the system of equations? {−3x+4y=−20y=x−4 (−4, −8) (4, 8) (−2, −6) (0, −5)
Answer:
Step-by-step explanation:
-3x + 4y = -20
y = x - 4
Put the second equation into the first equation in place of y.
-3x + 4 (x - 4) = -20
Multiply everything in the parenthesis by 4.
-3x + 4x - 16 = -20
Combine like terms.
x - 16 = -20
Add 16 to both sides.
x = -4
Put this into the second equation in place of x.
y = -4 - 4
y = -8
Your solution set is (-4,-8).

The Marine Discovery Aquarium sells ocean-themed cookies in their gift shop. Last month, they sold 65 shark cookies and 85 clown fish cookies. The cookies were so popular that they want to order more cookies this month. They plan to order 170 clown fish cookies this month. If they keep the same ratio, how many shark cookies should they order this month?
Answer: 130 shark cookies.
Step-by-step explanation: If you divided 170 clown fidh cookies by 85 clown fish cookies you get 2. So same as 85 times 2. Then do the same with the shark cookies. 65 times 2, that equals 130.
