Answer: well, just multiply x and y by the scale factor
Step-by-step explanation:A square with a perimeter of 20 units is graphed on a coordinate grid. The square is dilated by a scale factor
of 0.4 with the origin as the center of dilation.
If (x, y) represents the location of any point on the original square, which ordered pair represents the
coordinates of the corresponding point on the resulting square.

No Solutions 6−3+4x+1= x + One Solution 6−3+4x+1= x + Infinitely Many Solutions 6−3+4x+1= x +
Complete Question:
Complete each equation, so the statement about its solution is true.
No solutions:
6-3+4x+1= __x + __
One solution:
6-3+4x+1= __x + __
Infinitely many solutions:
6-3+4x+1 = __x + __
Answer:
[tex]4 + 4x = 4x + 3[/tex] --- No solution
[tex]4 + 4x = 3x + 2[/tex] --- One solution
[tex]4 + 4x = 4 + 4x[/tex] --- Infinitely Many solution
Step-by-step explanation:
Solving (a): No solutions
6-3+4x+1= __x + __
Collect like terms
6-3+1+4x= __x + __
4+4x= __x + __
To get no solution, the coefficient of x on both sides must be the same. However, the constant must be different.
So, we can equate the expression to:
[tex]4 + 4x = 4x + 3[/tex]
Solving (b): One solution
6-3+4x+1= __x + __
This gives (same as (a))
4+4x= __x + __
To get one solution, the coefficient of x on both sides must be different. The constant can have any value.
So, we can equate the expression to:
[tex]4 + 4x = 3x + 2[/tex]
Solving (c): Infinitely many solutions
6-3+4x+1= __x + __
This gives (same as (a))
4+4x= __x + __
To get infinitely many solutions, both sides of the equation must be equal.
So:
[tex]4 + 4x = 4 + 4x[/tex]

9. There are 150 fruits on a market stall.
54 are oranges and 72 are apples and the rest are pears.
What percentage of the fruit are pears?
You must show your calculations. 015)
(2 Points)
Answer:
24%
Step-by-step explanation:
150 = 54 + 72 = 126 + 24 = 150
24/100 = 24%
Ahhh...first we need to find out the percentage of the oranges+the apples. then take it away from 100%.
I did a bit of tinkering and figured out that the orange percentage is 36% of it.
([tex]\frac{150}{54} =\frac{75}{27} =36%[/tex]%)
That means that the apples are 48% and the pears are 100-(36+48)=100-84=16%

10x + 7y = –8
7x + 7y = –14
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )

Answer:
x = 180
∠DBC = 23
∠ABC = 157
Step-by-step explanation:
A straight line is always 180 degrees
A to D line = 180
6x + 19 + x = 180
7x + 19 = 180
-19 -19
7x = 161
/ 7 / 7
161 /7 = 23
x = 23
Then plug it in
6x + 19
6 ( 23 ) + 19 = 157
x
x = 23

1. Your friend Shawn tells you that he has been practicing flipping coins so that they will land on heads more frequently than tails. He claims that he can now flip a coin and yeh probability it will land on head is 4/3. Do you believe him? Why or Why not?
1. Find the 90% Cl for the population mean if sample
mean= 12, SD=2.3 and sample size is 65.
2. Find the 88% Cl for the population mean if sample
mean=23, SD=12, and sample size is 45.
3. Interpret #1 and #1.
Answer:
The answer is below
Step-by-step explanation:
1)
mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65
Given that the confidence level (c) = 90% = 0.9
α = 1 - c = 0.1
α/2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given as:
[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47[/tex]
The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)
2)
mean (μ) = 23, SD(σ) = 12, sample size (n) = 45
Given that the confidence level (c) = 88% = 0.88
α = 1 - c = 0.12
α/2 = 0.06
The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56
The margin of error (E) is given as:
[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8[/tex]
The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)
Plz help me I’m stuck and it’s important
Answer:
2 50ml bottles
Step-by-step explanation:
Reading through the question, we have:
For 80mL
[tex]C_1 = \pounds 55[/tex]
For 2 50mL bottles.
The cost is calculated by the original cost + half the original cost.
i.e.
[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]
[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]
[tex]C_2 = \pounds 67.5[/tex]
Next, is to calculate the unit price of each.
For 80mL
[tex]C_1 = \pounds 55[/tex]
[tex]Unit\ price = 55/80[/tex]
[tex]Unit\ price = 0.6875[/tex]
For 2 50mL bottles.
[tex]C_2 = \pounds 67.5[/tex]
[tex]Unit\ price - 67.5/(2 * 50)[/tex]
[tex]Unit\ price = 67.5/100[/tex]
[tex]Unit\ price = 0.675[/tex]
By comparison, the 2 50mL is the best buy because it has smaller unit price

For each fraction, write an equivalent fraction that has a denominator of 36.
1. 5/12 2. 1/6 3. 7/9
Answer:
Step-by-step explanation:
1) 5/12
To make the denominator to 36, 12 should be multiplied by 3. As we are multiplying the denominator by 3, numerator also should multiplied by 3
[tex]\frac{5}{12}=\frac{5*3}{12*3}=\frac{15}{36}[/tex]
2) 1/6
[tex]\frac{1}{6}=\frac{1*6}{6*6}=\frac{6}{36}\\[/tex]
3) 7/9
[tex]\frac{7}{9}=\frac{7*4}{9*4}=\frac{28}{36}[/tex]
