Which first step for solving the given system using substitution results in an equation without fractions
3x + y = 9
5x-3y=1
Slove for x in the first equation
Solve for y in the first equation
Solve for x in the second equation
Solve for y in the second equation
Answer:
Solve for x in the second equation.
Step-by-step explanation:
Subtract 3x from both sides and you can substitute y in the second equation for the first equation and solve for x.
Solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions. Option B is correct.
What is the system of two equations?A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The given equation in the problem is;
Equation 1: 3x + y = 9
Equation 2: 5x-3y=1
Equation 1;
3x + y = 9
y=9-3x
Equation 2:
5x-3y=1
5x+3(9-3x)=1
5x+27-9x=1
-4x=-26
x =6.5
Hence, solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions.
Hence, option B is correct.

Given the function f(x) = –22 – 7x + 18, determine the average rate of change
of the function over the interval -10 < x < -1.
Note: May be you meant to write the function as:
f(x)=-22x²-7x+18
Answer:
The Average rate of function = 235
Step-by-step explanation:
Given the function
f(x) = –22x² – 7x + 18
Interval = -10 < x < -1
so
taking x₁ = -9, x₂ = -2 in the interval
f(x₁) = f(-9) = -22(-9)² – 7(-9) + 18
= -1701
f(x₂) = f(-2) = -22(-2)² – 7(-2) + 18
= -56
Using the formula
Average rate of change = f(x₂) - f(x₁) / x₂-x₁
= (-56) - (-1701) / (-2) - (-9)
= (-56 + 1701) / (-2+9)
= 1645 / 7
= 235
Thus, the Average rate of function = 235
A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 38 minutes In 1 hour
Answer:
a) distance traveled is 16 miles.
b) distance traveled is 40 miles.
Step-by-step explanation:
Speed is a scalar quantity which describe the rate of distance moved with time.
i.e speed =
Given that: distance = 2 1/3 miles = miles, time = 3 1/2 minutes = minutes.
Then;
speed = ÷
= x
=
The car's steady speed is 0.67 miles per minute.
a) when the time is 24 minutes, the distance covered can be determine by:
distance = speed x time
= x 24
= 16
distance traveled is 16 miles.
b) When the time is 1 hour (60 minutes), the distance traveled can be determined by:
distance = speed x time
= x 60
= 40
distance traveled is 40 miles.

solve the equation below for x when y= 290
Answer:
If y = 290, x = 30
Step-by-step explanation:
y = 200 + 3x If y = 290
290 = 200 + 3x
290 - 200 = 3x
90 = 3x
90/3 = x
30 = x

PLEASE SHOW FULL SOLUTIONS. WILL MARK BRAINLIEST FOR THE BEST ANSWER. What is the approximate length of the fence around the field shown below? THANK YOU....
9514 1404 393
Answer:
398.12 m
Step-by-step explanation:
The perimeter fence consists of two half-circles (hence, a full circle) of radius 36.5 m, and two straight lengths of 84.39 m.
The circumference of a circle is given by the formula ...
C = 2πr
so the circular sections of fence have a total length of ...
C = 2π(36.5 m) = 73π m ≈ 229.34 m
__
Adding the two straight lengths to this gives a total perimeter of ...
P = 2(84.39 m) +229.34 m = 398.12 m
The approximate length of the fence around the field shown is 398.12 m.
_____
Comment on significant figures
Since the length of the straight section is given to the nearest cm, we have elected to give the total length accurate to the nearest cm. If we assume that the radius is only good to 3 significant figures, then the circumference of the circle is good only to 3 significant figures (229 m). Thus, we must give our approximate value to the same precision, the nearest meter: 398 m.

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet. What is Ruiz's percentage error?
0.6%
3.75%
3.9%
6%
Answer: 3.9%
Step-by-step explanation:
First, subtract the two values:
16 - 15.4 = 0.6
Now divide this to the actual area:
0.6 / 15.4 = 0.038961039
Multiply by 100:
0.038961039 * 100 = 3.8961039
So the percent error is approximately 3.9%
Answer:
3.75% Hope it helps

x = -1
Simply get the variable on one side of the equation alone and simplify:
2x = 5 - 21/3
2x = 15/3 - 21/3
2x = -6/3
2x = -2
x = -1

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in:
Answer:
the distance covered is 26.87 miles
Step-by-step explanation:
The computation of the distance covered is shown below:
As we know that
Speed = Distance ÷ Time
where
Speed is 8 2 ÷ 3 = 26 ÷ 3
And, the time required is 3 hours and 6 minutes i.e. 3 hours and 6 ÷ 60 = 3.1 hours
Now the distance covered is
= 26 ÷ 3 × 3.1
= 26.87 miles
hence, the distance covered is 26.87 miles

in a carton, 3 out of 10 glasses are cracked. what percent of glasses are not cracked?
Answer:
70%
Step-by-step explanation:
[tex]\frac{3}{10}[/tex] = [tex]\frac{30}{100}[/tex] = 30%
100 - 30 = 70
Answer:
70% are not cracked
Step-by-step explanation:
So 10 = 100%
So each bottle equals 10%
If 3 glasses are cracked it would be 30% cracked
So subtract 30 from 100 and you get 70%

Two opponents Playing chess start out with 32 pieces on the chess board . Each person loses an equal amount of pieces over 15 minutes . By this time , only 20 piece remain . How many pieces did each person lose ?
Answer:
Each individual lost 6 pieces
Step-by-step explanation:
Initially, there were 32 pieces
After a while, 20 was left
The number of pieces lost will be 32-20 = 12 pieces
We are told that equal number of pieces were lost
So the number of pieces lost per individual will be:
12/2 = 6 pieces

Select the correct answer. Which is the graph of the function f(x) = x^3 - 3x^2 - 4x?
Answer:
A
Step-by-step explanation:
The graph of function is given. The correct graph is D.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given,
function f(x) = x³ - 3x² - 4x
The properties of the function f(x) = x3 - 3x2 - 4x are as follows:
1) Factors: x (x+1) (x-4)
2) Zeros/roots: x = 0, x = -1, and x=4.
3) Leading coefficient is positive.
4) The graph rises to -1 on the x-axis before descending to cross through 0. It turns up once more through 4, then finishes by turning toward positive infinity.
5) Its graph resembles an upside-down S.
6) Its relative maximum value is 1.128, while its relative minimum value is -13.128.
The graph is given in the attached image.
Therefore, function graph is D.
