(-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
3. y = 1/3x - 2 = -10

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]

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.

Harvey the hamster can run 3 and 1/6 km in 1/4 of an hour. What is his average speed in kilometers per hour?
Thank you!
In decimal form, this is approximately 12.667 km per hour.
As an improper fraction, 12 & 2/3 = 38/3
==================================================
Explanation:
Let's use this formula
a & b/c = (a*c+b)/c
to convert the given mixed number to an improper fraction.
3 & 1/6 = (3*6+1)/6
3 & 1/6 = 19/6
The mixed number 3 & 1/6 is the same as the improper fraction 19/6
The hamster runs 19/6 km in 1/4 of an hour.
We can express that as the ratio
19/6 km : 1/4 hr
Multiply both parts by 4 so that the "1/4 hr" turns into "1 hr"
19/6 km : 1/4 hr
4*19/6 km : 4*1/4 hr
76/6 km : 1 hr
38/3 km : 1 hr
Harvey runs 38/3 km in 1 hour
Let's convert that to a mixed number
38/3 leads to a decimal, but 36/3 leads to a whole number
So,
38/3 = (36+2)/3
38/3 = 36/3 + 2/3
38/3 = 12 + 2/3
38/3 = 12 & 2/3
You can use your calculator to note that 38/3 = 12.667 approximately, which is also the value of 12 & 2/3, since 2/3 = 0.667 approximately. This helps confirm we did the conversion correctly.

Bone-shaped treats are 5 for $3.50 at Shelley's store and Sarah wants to buy 12. She set up and solved this proportion to find how much they would cost. Describe her error and find the correct solution. (5/3.5)=(12/x) 3.5x=60 x=17.14.
Answer:
Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)
Step-by-step explanation:
Sarah's calculation
Let
x = cost of 12 Bone-shaped treats
Quantity of Bone-shaped treats : price
5 : 3.5 = 12 : x
(5/3.5) = (12/x)
Cross product
3.5x=60 (Here is her error)
x=17.14
Correct calculation
Quantity of Bone-shaped treats : price
5 : 3.5 = 12 : x
5 / 3.5 = 12 / x
Cross product
5 * x = 3.5 * 12
5x = 42
x = 42 / 5
= 8.4
x = $8.4
Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)
Instead of multiplying Quantity of Bone-shaped treats by cost
Answer:
Sarah multiplied the denominator by the denominator and the numerator by the numerator instead of finding the cross products. The equation should be 5x = 42, so the cost should be $8.40.

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!
