which coordinate is a solution for the system containing the equations y=x+3 and y=4x?
Answers
Answer:
(1, 4 )
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 4x → (2)
Substitute y = 4x into (1)
4x = x + 3 ( subtract x from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4x = 4 × 1 = 4
Solution is (1, 4 )

Latrell and his cousin, Tisha, met at a state park to go for an all-day hike. Latrell drove 122 miles to get to the park, and it took him 2 hours. Tisha drove 96 miles to get to the park, and it took her 1.5 hours. On average, how much faster did Tisha drive than Latrell?
Answers
Answer:
3 miles
Step-by-step explanation:
122/2 is 61
64 plus 32 is 96. 96/1.5 is 64 meaning that she goes 64 miles an hour.
so she goes 3 miles faster on average than latrell, with latrell going 61 an hour average and her going 64 an hour average

Tisha is faster than Latrell by 3 miles/hour

She leaves home at 13:00 and arrives at the park at 13:30.
What is her average speed in km/h?
Answers
Answer:
Speed = 24 km/h
Step-by-step explanation:
Speed = Distance / Time
A cyclist travels 12 km from home to the park.
She leaves home at 13:00 and arrives at the park at 13:30.
Distance = 12 km
Time = 0.5 Hours
Speed = 12 / 0.5
Speed = 24 km/h
Answer:
Step-by-step explanation:
12 km to the park in 30 mins so multiply the 12 km by 2 to make a whole hour.
12*2= 24 km/h
In triangle ABC, AB measures 25 cm and AC measures 35 cm. The inequality < s < represents the possible third side length of the triangle, s, in centimeters. The inequality < p < represents the possible values for the perimeter, p, of the triangle, in centimeters.
Answers
Answer:
The inequality 10 < s < 60 represents the possible third side length of the triangle, s in centimeters.
The inequality 70 < p < 120 represents the possible values for the perimeter p, of the triangle in centimeters.
Step-by-step explanation:
Firsts one The lower number has to be the difference between the bigger number and smaller number. In this case 35 - 25 = 10 and the s < 60 has to be the sum of both numbers.
Second one. I'm assuming it's just the sum of the two numbers to the first answer, and the second number is just the second number from the previous one, but multiplied by 2. Sorry that I couldn't go into too much detail about this one
The inequality that represents the possible third side length
[tex]10cm<s<60cm[/tex]
The inequality that represents the possible values for the perimeter
[tex]70cm<P<120cm[/tex]
Given :
In triangle ABC, AB measures 25 cm and AC measures 35 cm.
For any triangle , we know that the sum of measures of two sides is greater than the third side
Let 's' be the third side length
[tex]25+35>s\\60>s\\\\Also , s+25>35\\s>35-25\\s>10\\Inequality\; is \;\\10<s<60[/tex]
Now we find the perimeter when s=10
Perimeter = sum of all the sides
[tex]s=10\\P=25+35+10=70\\s=60\\P=25+35+60=120[/tex]
[tex]70<P<120[/tex]

Quinton typically walks 28 yards south on Pine Street and 45 yards east on Maple Avenue in order to get to school. How much shorter would his walk be if he took the shortcut shown below? (50PTS)
Answers
Answer:
B- 20 yards
Step-by-step explanation:
First you have to find the hypotenuse by finding the square root of 28 squares plus 45 squared which equals 53 yards. Next you have to add the two legs of the right triangle so we can subtract the shortcut length from that. So you have to do 28 plus 45 which equals 73 yards. 73 minus 53 is 20. So the answer is 20 yards.

What is the inverse of the function f(x) = x - 9?
Answers
Answer:
F^-1(x) = x+9
Step-by-step explanation:
Hope this helps! Stay Safe!\
The inverse of the given function is f⁻¹(x) = x + 9. The correct option is a f⁻¹(x) = x + 9
From the question, the given function is
f(x) = x - 9
To determine the inverse of this function,
First, let y = f(x)That is,
y = x - 9
Now, make x the subject of the equationTo do that, add 9 to both sides
We get
y +9 = x - 9 +9
y + 9 = x
∴ x = y + 9
Now, rewrite as f⁻¹(x) by replacing y by xThat is,
f⁻¹(x) = x + 9
Hence, the inverse of the given function is f⁻¹(x) = x + 9. The correct option is a f⁻¹(x) = x + 9

Use the divisibility rules to determine which of the following numbers 330 is divisible by. (Check all that apply.)
2
3
5
7
11
Answers
The numbers that divide 330 are 2, 3, 5 and 11.
How to find the divisibility for a given number?In order to find divisibility, there are certain rules for different numbers. If a number is divisible by two numbers then it is also divisible by their product.
The given number is 330.
The divisibility rules for the number given can be applied one by one as follows,
Divisibility for 2,
For a number to be divisible by 2 its unit digit must be 0, 2, 4, 6 or 8.
Thus, 330 is divisible by 2.
Divisibility for 3,
For a number to be divisible by 3 sum of the digits of the number must be divisible by 3.
Since sum of the digits of 330 is 6 which is divisible by 3, 330 is also divisible by 3.
Divisibility for 5,
A number should either end with 0 or 5 in order to be divisible by 5.
Thus, 330 is divisible by 5 as it ends with 0.
Divisibility for 7,
For a number to be divisible by 7, the digit at ones place multiplied by 2 and then subtracted from the remaining digits must be divisible by 7.
Here, in 330 this rule is applied as,
33 - 2 × 0 = 33
Since 33 is not divisible by 7, 330 is also not divisible.
Divisibility for 11,
The difference of the sum of the digits at even place to the odd place must either be zero or divisible by 11.
In 330, 3 + 0 - 3 = 0.
Thus, 330 is divisible by 11.
Hence, the given number 330 is divisible by 2, 3, 5 and 11.
