Answer:
x = 4.8 , y = 4
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{KJ}{NP}[/tex] = [tex]\frac{KL}{NM}[/tex] , substitute values
[tex]\frac{x}{3}[/tex] = [tex]\frac{8}{5}[/tex] ( cross- multiply )
5x = 24 ( divide both sides by 5 )
x = 4.8
and
[tex]\frac{JL}{PM}[/tex] = [tex]\frac{KL}{NM}[/tex] , that is
[tex]\frac{6.4}{y}[/tex] = [tex]\frac{8}{5}[/tex] ( cross- multiply )
8y = 32 ( divide both sides by 8 )
y = 4
Solve the system of equations by the substitution method.
x−2y=−4 x+8y=16
Answer:
x=0, y=2
Step-by-step explanation:
x-2y=-4
-x+8y=16
-10y=-20
y=2
x-2y=-4
x-2(2)=-4
x-4=-4
x=-4+4
x=0

The function C(x)=17.5x-10 represents the cost (in dollars) of buying x tickets to the orchestra with a $10 coupon. How much does it cost to buy five tickets?
Answer:
8 tickets
Step-by-step explanation:
x = 10 in the given equation.
We have then:
C (x) = 17.5x - 10
C (10) = 17.5 * (10) - 10
C (10) = 165
Answer:
to buy 10 tickets cost:
$ 165
b. How many tickets can you buy with $ 130?
For this case we must make the substitution: C (x) = 130
We have then:
C (x) = 17.5x - 10
130 = 17.5x - 10
Clearing x we have:
17.5x = 130 + 10
17.5x = 140
x = (140) / (17.5)
x = 8
Answer:
You can buy 8 tickets with $ 130
A function is a relation in which every input has exactly one output.
Which choice represents a function?
CLEAR CHECK
Inputs: negative 4, 5, 8, negative 5. Output: 4, 3, 9, negative 5). Negative 4 goes to 4 and 3. 5 goes to 3. 8 goes to 9. negative 5 goes to negative 5.
On a coordinate plane, a vertical line goes through x = 3.

Answer:
On a coordinate plane, a vertical line goes through x = 3.
Step-by-step explanation:
I haven't looked at the other choices, but clearly this is a function
Answer:
will find at bottom
Step-by-step explanation:
A relation is a function of x if each value of x in the domain corresponds to exactly one value of y in the range. In other words, there should be no repeated values of x with different values of y.
Let's analyze each of the given tables to determine which one represents a function of x:
1. Table 1: In this table, we have x values of -1, 2, 2, and 3. Notice that x = 2 appears twice with different y values. This violates the definition of a function, so Table 1 is not a function of x.
2. Table 2: This table has x values of -8, -8, 1, and 1. Similar to the previous table, x = -8 and x = 1 appear twice with different y values. Therefore, Table 2 is not a function of x.
3. Table 3: In this table, all the x values are the same, which is -5. However, the corresponding y values are different (-9, 7, -9, and 2). Since each x value has a unique y value, Table 3 represents a function of x.
4. Table 4: This table consists of x values of -3, -2, 4, and 7. Each x value corresponds to a unique y value (-1, 5, 0, and -1). Therefore, Table 4 also represents a function of x.
To summarize, the relations that are functions of x are Table 3 and Table 4.

Find volume
Answer:
357.5cm³
Step-by-step explanation:
To find the volume of the prism, find the area of the triangle and multiply it by the height
Area of the triangle
a = 1/2 × base × height (of the triangle)a = 1/2 × 22 × 5 = 55cm²Volume of prism
55 × 6.5 = 357.5cm³Answer: 357.5cm³

One of Kylie's homework problems is to convert 30 centimeters to feet, given that 2.54 centimeters = 1 inch. Here is her
work:
30 centimeters
2.54 centimeters 12 inches
= 30 x 254x12=914 4 feet
1 inch 1 foot
Which of the following statements is true?
Kylie's conversion is correct
Kylie's conversion is incorrect because she set up the conversion ratios incorrectly.
Kylie's conversion is incorrect because she multiplied incorrectly
Kylie's conversion is incorrect because her conversion ratios are not equivalent to 1.
Answer:
She set up the conversion ratios incorrectly.
Step-by-step explanation:
30 cms
= 30 / 2.54 inches
= 30 / 2.54 / 12feet
= 0.984 feet.

When converting from inches to feet, the measurement in inches, m, of an object varies directly with its measurement in feet, f, with the constant of variation being 12.
What is the equation relating these two quantities?
How many inches would a 3.5-foot object measure?
inches
How many feet would a 27-inch object measure?
Step-by-step explanation:
wow, how complicated can one phrase this ...
the point being :
1 ft = 12 in and vice versa (1 in = 1/12 ft)
so, any measurements given in feet but needed in inches need to be multiplied by 12.
and any measurements given in inches but needed in feet need to be divided by 12.
so,
3.5 ft = 3.5×12 = 7/2 × 12 = 7×6 = 42 in
27 in = 27/12 = 9/4 = 2 1/4 or 2.25 ft
Answer:When converting from inches to feet, the measurement in inches, m, of an object varies directly with its measurement in feet, f, with the constant of variation being 12.
What is the equation relating these two quantities?
✔ m = 12f
How many inches would a 3.5-foot object measure?
✔ 42
inches
How many feet would a 27-inch object measure?
