i just need x and y please
Answer:
Step-by-step explanation:
Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> 3 3/17
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
y= 14.25

Let f(x)= x^2 -5x+4 and g(x)=2^x-3
Answer:
Plug g(x) into all the x values in your f(x) and the answer is 3 because it makes the denominator 1-1 which makes it 0 and is thus discontinuous

Which equation represents the graph shown?
Step-by-step explanation:
The graph is a linear equation starting at 0.
form y = mx + b.
starts at 0, so b = 0, so the 2nd and 3rd choices are incorrect.
change in y/change in x is the slope,
and you can see it goes up about 35 in the y direction for every 1 in the x, so the slope is 35.
so it's the first answer.
The linear equation of the graph is y = 35x. So, the option first is correct.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form y = mx + b.
The graph is a linear equation origin at 0.
Since b = 0, the 2nd and 3rd choices are incorrect.
The slope = change in y/change in x
Here, we can see that it goes up about 35 in the y-direction for every 1 unit of in the x, so the slope is 35.
so the first answer is correct which is y = 35x.

Rewrite, using the distributive
property.
-3(5x – 10) = [?]x +[ ]
Answer:
-15x + 30
Step-by-step explanation:
Using the distributive property, distribute -3 to the parentheses:
-3(5x) = -15x
-3(-10) = 30
Add these terms together:
-15x + 30 is the rewritten expression
Answer:
-15x + 30
Step-by-step explanation:
-3*5 = -15 and -3 * -10 equals 30 also negative times a negative is always a positive number

how will you know that the equation is a quadratic
Answer:
A quadratic condition is a condition of the subsequent degree, which means it contains, in any event, one term that is squared. The standard structure is ax² + bx + c = 0 with a, b, and c being constants, or mathematical coefficients, and x is an obscure variable.

2,500
Step-by-step explanation:
100 random samples were taken from a large population. A particular numerical characteristic of sampled items was measured. The results of the measurements were as follows: 45 measurements were between 0.859 and 0.900 0.901 was observed once 0.902 was observed three times 0.903 was observed twice 0.904 was observed four times The smallest value was 0.859, and the largest value was 0.958. The sum of all 100 measurements was 91.170. Except those noted, no measurements occurred more than twice. What is the median of the measurements
Answer:
The median is [tex]Median = 0.903[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 100
The [tex]1^{st} \to 45^{th}[/tex] measurements is [tex]= 0.859 \to 0.900[/tex]
Generally since that after 0.900 we have 0.901 , then the
[tex]46^{th} \ measurement \ is \ 0.901[/tex]
in the same manner the [tex]47^{th} \ measurement \ is \ 0.902[/tex],
Given that 0.902 was observed three times it means that
[tex]47^{th},48^{th},49^{th} \ measurement \ is \ 0.902[/tex],
Given that 0.903 was observed two times it means that
[tex]50^{th},51^{th} \ measurement \ is \ 0.903[/tex],
Given that 0.903 was observed four times it means that
[tex]52^{nd},53^{rd},54^{th},55^{th} \ measurement \ is \ 0.904[/tex],
Given that the highest measurement is 0.958 then then the [tex]56^{th} \to 100^{th} \ measurement \ is \ between \ 0.905 \to 0.958[/tex]
Generally the median is is mathematically represented as
[tex]Median = \frac{ [\frac{n^{th}}{2}] + [(\frac{n}{2})^{th} + 1 ]}{2}[/tex]
=> [tex]Median = \frac{ [\frac{100^{th}}{2}] + [(\frac{100}{2})^{th} + 1 ]}{2}[/tex]
=> [tex]Median = \frac{ [50^{th}] + [51^{th} ]}{2}[/tex]
=> [tex]Median = \frac{ 0.903 + 0.903}{2}[/tex]
=> [tex]Median = 0.903[/tex]

w = 4
L = 7
Step-by-step explanation:
L = length of rectangle
w = width of rectangle
L = 3 + w
A = 28
A = L*w
=(3+w) * w
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7
Explain how rates and ratios are related. Be sure to include examples to support you response.
Answer:
Both rates and ratios are a comparison of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit. For example, in a room full of students, there are 10 boys and 5 girls. This means the ratio of boys to girls is 10:5.

Stan’s Skate Shop is having a sale on skateboards. The original price for its Extreme Skate Board was $84.50. The sale price for the skateboard is $50.70. What is the percent decrease in the price of the skateboard?
Answer:
It is 60%
Step-by-step explanation:
84.50 x 0.60% = 50.7 (also 50.70)
I hope my answer helps even though I am in middle school :)
The required percent decrease in the price of the skateboard is 40%.
The original price for its Extreme Skate Board was $84.50. The sale price for the skateboard is $50.70. What is the percent decrease in the price of the skateboard is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Original price = $84.50
sale price = $50.70
Percent decrese = 84.50-50.70/84.50 × 100 = 40%
Thus, the required percent decrease in the price of the skateboard is 40%.

Answer:
B. x +6y = 4.45; x +12y = 5.65
Step-by-step explanation:
The problem statement defines the variables for you. Using x and y for the cost of a loaf and the cost of an egg, respectively, each purchase can be represented by an equation of the form ...
(number of loaves)x + (number of eggs)y = (amount spent)
The first purchase is described as
number of loaves = 1number of eggs = 6amount spent = 4.45equation: x +6y = 4.45The second purchase is of a dozen eggs, which is 12 eggs. The description of this purchase can be ...
number of loaves = 1number of eggs = 12amount spent = 5.65equation: x +12y = 5.65The situation can be represented by the equations shown in the attachment.

Answer:
if x = 12; y = 40
if x = 3; y= 13
Step-by-step explanation:
if x = 12 then,
y = 3(12) + 4
y = 36 + 4
y = 40
if x = 3 then,
y = 3(3) + 4
y = 9 + 4
y = 13
