B.X + y = 5 1 + -4 = -3 Nope same as A unless X is somehow not equal to x,
C. xy = 5 1(-4) = -4 Nope and does not even qualify as a line.
D. x - y = .5 1 - (-4) = 5 Nope unless you have a typo adding an unwanted decimal point
Estimate 25.65 + 13.23 + 6.35 by rounding each number to the nearest tenth.
a. 26 + 13 + 6 = 45
b. 25.7 + 13.2 + 6.4 = 45.3
c. 25.6 + 13.2 + 6.3 = 45.1
d. 25.7 + 13.3 + 6.4 = 45.4
Answer:
b. 25.7 + 13.2 + 6.4 = 45.3Step-by-step explanation:
25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4
25.65 + 13.23 + 6.35 =25.7 + 13.2 + 6.4 = 45.3Correct choice is b.

Tyler ate 7 hot dogs in 4 minutes. At this rate, how long would it take him to eat 23 hot dogs? Write a proportion, then solve. Round to the nearest tenth.
(7 hot dogs)/(4 minutes) = (23 hot dogs)/(x minutes)
7/4 = 23/x
7x = 4*23 .... cross multiplication
7x = 92
x = 92/7
x = 13.142857 approximately
x = 13.1
Answer: 13.1 minutes (approximate)five times x equals one
Answer:
x=0.2

in the similarity transformation of abc to def, abc was dilated by a scale factor of [?], reflected across the [ ], and moved through the translation [ ].
The complete similarity transformation is: triangle abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].
How to complete the similarity statement?From the figure, we have:
AB = 2 units
DE = 4 units
So, the scale factor (k) is:
k = DE/AB
k = 4/2
k = 2
So, the scale factor is 2
Also, both shapes are on either sides of the x-axis, and they are equidistant from the x-axis.
This means that the triangle is reflected across the x-axis with no translation.
Hence, the complete similarity transformation is:
abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].

a² + b² = 1,520
Step-by-step explanation:
a + b = 40ab = 40a² + b²
= (a + b)² - 2ab
= 40² - 2(40)
= 1,600 - 80
= 1,520
The value of y varies directly with x. If x = 195 when y = 15, what is the value of x when y = 9?
Since the value of y varies directly with x, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]
Given the following data:
x = 195y = 15To find the value of x when y = 9:
This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.
First of all, we would determine the constant of proportionality (k) for the mathematical expression.
[tex]y = kx\\\\15 = 195k\\\\k = \frac{195}{15}[/tex]
k = 13
Now, we can find x:
[tex]y = kx\\\\9 = 13x\\\\x = \frac{9}{13}[/tex]
Therefore, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

Given the graph of a proportional relationship, if the (2,7) lies on the graph, what is the value of k? What is the equation of the line?
Answer:
k=3.5, and y=3.5x is the equation of the line
Step-by-step explanation:
y and x are proportional means that y = kx for some constant k.
Thus, when y=7 and x=2, we have that 7 = k * 2, so that k = 7/2 = 3.5,
and the equation of the line is y = 3.5x

a patio furniture set sells for $935 on installment plan, which includes finance charge the payment plan calls for 15 percent down and the balance in 12 equal paymnets. the ampount of the payment is
The monthly payment for the patio furniture will be $66.23
Cost of the patio furniture = $935
Since there's a 15% down payment, then the amount that the buyer will pay will be:
= 15% × $935
= 0.15 × $935
= $140.25
Therefore, the amount that is left to pay will be:
= $935 - $140.25
= $794.75
Since the balance will be paid for 12 months, the monthly payment will be:
= $794.75 / 12
= $66.23

What common ratio would cause a geometric series to converge
Answer:0
Step-by-step explanation:
The sum of a convergent geometric series can be calculated with the formula a ⁄ 1 – r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1. So the answer is 0
