Answer:
x=3√5
Step-by-step explanation:
This is a right angle triangle
So the equation is
2²+x²=7²
x=√7²-2²
x=3√5
Answer:
x=3√5
Step-by-step explanation:
Consider this equation: 9x - 7 - 3x + 9 = x + 7 + 5x + 9. How many solutions does this equation have?
Step-by-step explanation:
9x - 7 - 3x + 9 = x + 7 + 5x + 9
6x + 2 = 6x + 16
2 = 16
Since 2 = 16 is false, there exist no real solutions for x.
Final Answer: No Solution. The equation would have 0 solutions.
Steps/Explanations:
Hey there! The answer is No Solution because -7 = 7. If 7 = 7, then it would be true and have one solution, which is not the case here.
Step 1: You should cancel [tex]9[/tex] on both sides.
[tex]9x - 7 - 3x = x + 7 + 5x[/tex]
Step 2: Simplify [tex]9x - 7 - 3x[/tex] to [tex]6x - 7[/tex].
[tex]6x - 7 = x + 7 + 5x[/tex]
Step 3: Simplify [tex]x + 7 + 5x[/tex] to [tex]6x + 7[/tex].
[tex]6x - 7 = 6x + 7[/tex]
Step 4: You'll need to cancel [tex]6x[/tex] on both sides.
[tex]- 7 = 7[/tex]
Step 5: Since [tex]-7 = 7[/tex] is false, there would be no solution.
No Solution

19(2m−16)=13(2m+4) (pls helppp)
Answer:
Simplified this is -304 + 38m = 52 + 26m
m in the equation is 29 2/3
Step-by-step explanation:
Reorder the terms:
19(-16 + 2m) = 13(2m + 4)
(-16 * 19 + 2m * 19) = 13(2m + 4)
(-304 + 38m) = 13(2m + 4)
Reorder the terms:
-304 + 38m = 13(4 + 2m)
-304 + 38m = (4 * 13 + 2m * 13)
-304 + 38m = (52 + 26m)
Simplfied answer:
-304 + 38m = 52 + 26m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-26m' to each side of the equation.
-304 + 38m + -26m = 52 + 26m + -26m
Combine like terms: 38m + -26m = 12m
-304 + 12m = 52 + 26m + -26m
Combine like terms: 26m + -26m = 0
-304 + 12m = 52 + 0
-304 + 12m = 52
Add '304' to each side of the equation.
-304 + 304 + 12m = 52 + 304
Combine like terms: -304 + 304 = 0
0 + 12m = 52 + 304
12m = 52 + 304
Combine like terms: 52 + 304 = 356
12m = 356
Divide each side by '12'.
m = 29.66666667
Simplifying
m = 29.66666667 = 29 2/3

The air temperature is −12 °C at sunrise and rises 3 °C every hour for several hours. The air temperature after x hours is represented by the function f(x) = 3x − 12. Find the intercepts
Answer:
4 and -12Step-by-step explanation:
The standard form of writing the linear equation of a line is expressed as;
f(x) = mx + c where;
m is the slope
c is the intercept
Given the function f(x) = 3x − 12
x intercept occurs at f(x) = 0
0 = 3x - 12
3x = 12
x = 12/3
x = 4
Hence the x intercept is 4
y intercept occurs at x = 0
f(x) = 3(0) - 12
f(x) = -12
Hence the y intercept is at -12
Jerry is paid twice a month. Last month, his first paycheck was for $52. He paid $18 for gasoline and $20 for food. His next paycheck was for $65. He paid $16 for gasoline and $25 for food. What is his balance?
Answer:
Jerry's current balance is $41.
Step-by-step explanation:
We need to subtract what he spent, and add what he gained.
So:
(Money spent)
$18 + $20 = $38
(Current balance)
$52 - $30 = $22
(Current balance)
$65 + $22 = $87
$25 + $16 = $41
Current balance: $41

Answer:
C. y + 7 = -7(x - 3)Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where m is the slope and (x₀, y₀) is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
y + 7 = -7(x - 3)

Which of the following best approximates the line of best fit?
Step-by-step explanation:
Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.
The answer is D.
The solution is, The graph that best approximates the line of best fit is option D.
Here, we have,
we know that,
Line of Best Fit:
This refers to the line that is used in a scatter plot to show and indicate a relationship between the points so that the number of points above the line is equal to the points below the point.
Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.
Hence, from the given illustration of graphs, we can see that using the eyeball method, we can see that the number of points in option D is best balanced between the line above and below.
The answer is D.

5(x - 11) - 2(x - 3) = 20 ← distribute and simplify left side )
5x - 55 - 2x + 6 = 20
3x + 49 = 20 ( add 49 to both sides )
3x = 69 ( divide both sides by 3 )

Answer:
BF = 18
Step-by-step explanation:
In triangle BCD, H is the Centroid.
Centroid of a triangle divides the median in the ratio 2 : 1.
Therefore, BH : HF = 2 : 1
Let BH = 2x & HF = x
Since, HF = 6.... (given)
So, x = 6
2x = 2*6 = 12
BH = 12
Now,
BF = BH + HF = 12 + 6
BF = 18

Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue
Answer:
14 pounds of meat
Step-by-step explanation:
Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue
We have to find the sum of the the total pounds of meat.
This is calculated as:
4 5/6 pounds + 3 1/3 pounds + 5 5/6 pounds
[(4 + 3 + 5) + (5/6 + 1/3 + 5/6)] pounds
The Lowest Common Denominator
= 6
Hence:
[12 + (5 + 2 + 5 /6)] pounds
= 12 + 12/6
= 12 + 2
= 14 pounds of meat
Hence, Jose has 14 pounds of meat
When James family went on the road to the carnival they were stuck in traffic. After a 20 minutes they are were 30 more miles left, after 35 minutes passed. How many more miles are left? If the fair is 58 miles away?
Answer:
They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

At Irtaza's Deli he is selling 7 oranges for $5.99 and Brianna's Food Mart is selling them 10 for $8.99. Where would you go shopping and why?
Answer:
At Irtaza's Deli
Step-by-step explanation:
For this you should find the unit price and whichever is less is where you should go.
(1) Irtaza Deli:
First I would round the 5.99 to 6 then we'll do 6 divided by 7.
[tex]\frac{6}{7}=.8571428571=.86[/tex]
(2) Brianna's Food Mart:
First I would round the 8.99 to 9 then we'll do 9 divided by 10.
[tex]\frac{9}{10}=.9[/tex]
Now let's compare:
So the first store sells oranges for $.86 and the second store sells them for $.90. I don't know about you but I would go to the first store they would be much more cheaper.

How does the percent equation relate proportional quantities?
Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
