Answer:
5. 1) C. 3/2·x + y = 2 ↔ y = -3/2·x + 2
6. 2) A. y = -2/3·x + 2 ↔ 2·x + 3·y = 6
7. 3) D. y = 3/2·x + 2 ↔ y = 3/2·x + 2
8. 4) E. y = 2·x + 2 ↔ -6·x + 3·y = 6
9. 5) B. 3·x + y = 6 ↔ y = -3·x + 6
10. 6) y = 5/4·x - 10, and y = 5/4·x - 11
11. 7) y = -8·x + 15 and y = -8·x + 16
12. 8) 4·x + y = 7 and 4·x + y = 6
13. 9) No
14. 10) Yes
Step-by-step explanation:
Two equations will have an infinitely many solutions when that represent the same equation
5. 1) C. 3/2·x + y = 2 is the same equation as y = -3/2·x + 2
6. 2) A. y = -2/3·x + 2 is the same equation as 2·x + 3·y = 6 (divide by 3 and make y the subject of the equation)
2·x/3 + 3·y/3 = 6/3 = 2
y = -2/3·x + 2
7. 3) D. y = 3/2·x + 2 is the same equation as y = 3/2·x + 2
8. 4) E. y = 2·x + 2 is the same equation as -6·x + 3·y = 6
-6·x/3 + 3·y/3 = 6/3 = 2
y = 6·x/3 + 2 = 2·x + 2
9. 5) B. 3·x + y = 6 is the same equation as y = -3·x + 6
3·x + y = 6
- 3·x + 3·x + y = -3·x + 6
y = -3·x + 6
Two straight line equations of the form, y = m·x + c, will have no solutions if they represent parallel lines and therefore, have equal slopes, m and different "y" intercepts, c
10. 6) For y = 5/4·x - 10, we have the slope, m = 5/4 and the "y" intercept c = -10
Therefore, the equation that will make a system with "no solution" has the same value for "m" and a different value for "c" such as y = 5/4·x - 11
11. 7) For y = -8·x + 15, similarly we have a system with "no solution" as follows;
y = -8·x + 15 and y = -8·x + 16
12. 8) For 4·x + y = 7, a system with "no solution" can be written as follows;
4·x + y = 7
∴ y = - 4·x + 7 which gives;
y = - 4·x + 7 and y = - 4·x + 6
From y = - 4·x + 6, we have;
4·x + y = 6
The system with "no solution" can therefore also be written as follows;
4·x + y = 7 and 4·x + y = 6
13. 9) No the sum of the two numbers and the result forms a function with the sum of the two numbers being the inputs of the function and their value, 8 being the output of the function and therefore, the input of a function can not have multiple outputs which are 8 and 10 which makes it not possible
14. 10) Yes, by the definition of a function, it is possible for two different inputs to a function to have the same output, therefore, given that the operation performed on the two inputs are different, the two inputs can be considered as different an can have he same output
For example, we have 8 + 0 = 8 and 8 - 0 = 8.
A baker bakes 50 muffins. 1/5 of the muffins are chocolate chip. 1/2 of the muffins are blueberry. The rest are cinnamon. How many cinnamon muffins does the baker bake?
Answer:
15 muffins are cinnamon.
Step-by-step explanation:
Given that:
Number of muffins baked = 50 muffins
Chocolate chip muffins = 1/5 of 50 = [tex]\frac{1}{5}*50[/tex]
Chocolate chip muffins = 10 muffins
Blueberry muffins = 1/2 of 50 = [tex]\frac{1}{2}*50[/tex]
Blueberry muffins = 25
Cinnamon muffins = Muffins baked - chocolate chip muffins - blueberry muffins
Cinnamon muffins = 50 - 10 - 25
Cinnamon muffins = 50 - 35 = 15
Hence,
15 muffins are cinnamon.
the price of a 5 minute phone call is $1.25 what is the price of a 17 minute phone call?
Answer:
$4.25
Step-by-step explanation:
Answer:
The price of 17 minutes call = $4.25
Step-by-step explanation:
Given
Minutes spent = 5 minutesCost of 5 minute call = $1.25Thus,
The unit rate can be calculated
Unit rate = $1.25 / 5 minutes
Unit rate = $0.25 per minute
So,
The price of one minute call = $0.25
The price of 17 minutes call = 0.25 × 17
= $4.25
Therefore, the price of 17 minutes call = $4.25

solve the system of equations:
-5x+2y=1
-8x+9y=19
X=?
Y=?
2y=1+5x (moving 5x to the other side) {equation 1}
Y= (1+5x)/2 (dividing both sides by 2)
Substitute {Y=(1+5x)/2} into equation: (-8x+9y=19)
Therefore giving you:
-8x+9(1+5x)/2=19
-8x+(9+45x)/2=19
(multiply through by 2 to remove the fraction)
-16x+9+45x=38
45x-16x=38-9(grouping like terms)
29x=29
Divide both sides by 29
X=1
Substitute X=1 into equation (-5x+2y=1)
-5(1)+2y=1
(-5)+2y=1
2y=1+5
2y=6
2y/2=6/2 (dividing both sides by 2)
Y=3.
:X=1 and Y=3
Answer:
X = 1
Y = 3
Step-by-step explanation:
Given equations are;
-5x+2y=1 Eqn 1
-8x+9y=19 Eqn 2
Multiplying Eqn 1 by -8
-8(-5x+2y=1)
40x - 16y = -8 Eqn 3
Multiplying Eqn 2 by 5
5(-8x+9y=19)
-40x+45y=95 Eqn 4
Adding Eqn 3 and 4
40x - 16y - 40x + 45y = 95 - 8
29y = 87
Dividing both sides by 29
[tex]\frac{29y}{29}=\frac{87}{29}\\y = 3[/tex]
Putting y = 3 in Eqn 1
-5x + 2(3) = 1
-5x + 6 = 1
-5x = 1 - 6
-5x = -5
x = 1
Hence,
X = 1
Y = 3

Step-by-step explanation:
A regular polygon has 72 sides.
Find the size of each of its interior angles.
The formula for finding the measure of each interior angle is below.
180(n - 2) / n where n represents the number of sides.
Since the polygon has 72 sides, we plug a 72 in for n.
So we have 180(72 - 2)/72 or 180(70)/72 which is 12600/72 or 175.
So the measure of each interior angle is 175 degrees.

bill has 9 1/3 cups of blueberries. he is using half of them to make blueberry tarts. if each tart will have 2/3 cups of blueberries, how many tarts can bill make?
Answer:
7 tarts
Step-by-step explanation:
1st step: find half of 9 1/3 = 28/3 x 1/2 = 14/3
2nd step: divide 14/3 by 2/3 so you multiply by the reciprocal of the 2nd fraction
14 x 3 = 7
3 2
Answer:
7 tarts
Step-by-step explanation:
First, lets make 9 1/3 into a full fraction. You can multiply 9x3 and add it to the numerator, which makes the fraction 28/3. Then it says half of the amount. "of" means to multiply, so lets do 28/3 x 1/2. We should get 28/6. Now, since each tart has 2/3 cups of blueberries, we should divide our fraction by 2/3 to find the amount of tarts. So 28/6 divided by 2/3. We can use KCF on 2/3 which makes the equation into 28/6 x 3/2. Finally, we should get 84/12, which simplified is 7.

[tex]4\frac{1}{2} -3 \frac{5}{6}[/tex]
1. Turn it into an improper fraction
[tex]4\frac{1}{2}[/tex] = [tex]\frac{9}{2}[/tex]

Answer:
A is ur answer
Step-by-step explanation:
a^2 + b^2 = c^2
c = 20
A.) Correct
u = 10√3
v = 10
u^2 + v^2 = c^2
10 = √100
√100 • √3 = √300
√300^2 + 10^2 = c^2
300 + 100 = c^2
400 = c^2
√400 = √c^2
20 = c
B.) Incorrect
u = 20√3
v = 10
u^2 + v^2 = c^2
20 = √400
√3 • √400 = √1200
√1200^2 + 10^2 = c^2
1200 + 100 = c^2
1300 = c^2
√1300 = √c^2
√1300 ≈ 36
C.) Incorrect
u = 20√3
v = 10√2
u^2 + v^2 = c^2
20√3 = √1200
10√2 = √200
u^2 + v^2 = c^2
√1200^2 + √200^2 = c^2
1200 + 200 = c^2
1400 = c^2
√1400 = √c^2
√1400 ≈ 37
D.) Incorrect
u = 10√3
v = 10√2
u^2 + v^2 = c^2
10√3 = √300
10√2 = √200
u^2 + v^2 = c^2
√300^2 + √200^2 = c^2
300 + 200 = c^2
500 = c^2
√500 = √c^2
√500 ≈ 22

Answer:
5b - 0.9b, distributive property
Step-by-step explanation:
The expression that is used to find the price of 5 loaves of bread is given by :
5(b-0.18b)
We need to rewrite the above expression.
Distributive property : a(b+c) = ab + ac
Here, a = 5, b = b and c = -0.18b
5(b-0.18b) = 5(b) + 5(-0.18b)
= 5b - 0.9b
So, the equivalent expression is 5b - 0.9b. The distributive property was used to rewrite the expression.
What is the rate in miles per gallon: gallons used: miles; 28 628.4 39 947.7 42 1020.6
Answer:
Step-by-step explanation:
What is the rate in miles per gallon:
gallons used: 28 39 42
miles; 628.4 947.7 1020.6
The answer is below
Solution:
A linear function is a function in the form:
y = mx + b; where y is a dependent variable, x is an independent variable, m is the rate of change of y with respect to x, and b is the initial value of y when x is zero.
From the table, we are given the gallon used to cover a distance in miles. To calculate the rate, we can select two points from the table. Using the points in the form (miles, gallons used): (628.4, 28) and (1020.6, 42) we get:
[tex]m=\frac{1020.6-628.4}{42-28}\\\\m=28\ miles\ per\ gallon[/tex]
Investors buy a studio apartment for $200,000. Of this amount, they have a down payment of $30,000. Their down payment is what percent of the purchase price? What percent of the purchase price would an $80,000 down payment be?
Answer:
$30,000 down payment is 15% of purchase price
$80,000 down payment would be 40% of purchase price
Step-by-step explanation:
x = percent of purchase price
30,000 = 200,000x
3/20 = x
3/20 = 15/100 = 15%
80,000 = 200,000x
8/20 = x
8/20 = 40/100 = 40%

Step-by-step explanation:
We can simplify the ratio 12 : 32 by dividing both terms by the greatest common factor (GCF).
The GCF of 12 and 32 is 4.
Divide both terms by 4.
12 ÷ 4 = 3
32 ÷ 4 = 8
