Solve each system using substitution.
1. 4x= 3y-2 ; 18= 3x+y
Answer:
y = 6
Step-by-step explanation:
so since you have 2 variables, you need to find a substitution for one of them.
let's do that for y
let y = something in the second equation.
y = 18 - 3x
then plug this into the first equation
4x = 3(18 - 3x) - 2
4x = 54 - 9x -2
4x = 52 - 9x
13x = 52
x = 4
now you have x, plug it into any of the equations to find y.
4(4) = 3y - 2
16 = 3y - 2
18 = 3y
y = 6
Answer:
x = 4, y = 6
Step-by-step explanation:
Substituting y into 1:
4x= 3y-2 -----1
18= 3x+y -----2
Isolate the y in 2.
y = 18-3x -----3
Substitute 3 into 1.
4x= 3(18-3x)-2
Evaluate.
4x = 54-9x-2
Keep like terms together.
4x+9x = 54-2
Simplify.
13x = 52
Find x.
x = 52 ÷ 13
= 4
Substitute x into 3.
y = 18-3(4)
Evaluate.
y = 18-12
Find y.
y = 6

Montreal 136.2
Regina 132.3
Saskatoon 132.2
Yellowknife 138.9
Required:
a. Find the sample mean (in cents).
b. Find the sample standard deviation (in cents).
c. Find a 90% confidence interval for the mean gasoline price per liter across urban Canada in May 2011. Provide the lower and upper limits for your confidence interval.
d. Find a 95% confidence interval for the mean gasoline price per liter across urban Canada in May 2011. Provide the lower and upper limits for your confidence interval.
Answer:
135.05 ; 2.762 ; (133.201, 136.899) ; (132.840, 137.260)
Step-by-step explanation:
Given the data:
Urban area Price/liter
St. John, NL 137.1
Halifax 133.6
Montreal 136.2
Regina 132.3
Saskatoon 132.2
Yellowknife 138.9
Mean = (137.1 + 133.6 + 136.2 + 132.3 + 132.2 + 138.9) / 6
= 810.3 / 6
= 135.05
Standard deviation (σ) : √Σ(X - mean)²/n-1
(137.1 - 135.05)^2 + (133.6 - 135.05)^2 + (136.2 - 135.05)^2 + (132.3 - 135.05)^2 + (132.2 - 135.05)^2+ (138.9 - 135.05)^2 = 38.135
√(38.135 / (6 - 1))
= √7.627
= 2.7617023
= 2.762
C.)
90% confidence interval of the mean :
Mean ± Zcrit * σ/√n
Zcrit at 90% = 1.64
135.05 ± 1.64 * (2.762/√6)
135.05 ± 1.64 * 1.1275817
Lower Value = (135.05 - (1.64 * 1.1275817)) = 133.201
Upper Value = (135.05 + (1.64 * 1.1275817))) = 136.899
Confidence interval = (133.201, 136.899)
D.)
95% confidence interval of the mean :
Mean ± Zcrit * σ/√n
Zcrit at 95% = 1.96
135.05 ± 1.96 * (2.762/6)
135.05 ± 1.96 * 1.1275817
Lower Value = (135.05 - (1.96 * 1.1275817)) = 132.840
Upper Value = (135.05 + (1.96 * 1.1275817)) = 137.260
Confidence interval = (132.840, 137.260)
Quincy rides his bicycle 1 mile in 4 minutes, and his sister Marissa runs 13,376 feet in 16 minutes. In miles per hour approximately how much faster is Quincy than Marissa? (Note: 1 mile = 5,280 feet)
Answer:
Quincy is 5.5 mi/h faster than Marissa
Step-by-step explanation:
Speed
It's required to compare the speed of Quincy and Marissa knowing that Quincy rides his bicycle 1 mile in 4 minutes.
The speed can be calculated as the distance by the time, but it's required to express the speed in miles/hour.
4 minutes is 4/60 = 0.0667 hours, thus Quincy's speed is:
[tex]\displaystyle \frac{1\ mile}{0.0667\ h}=15\ mi/h[/tex]
Quincy rides at 15 miles/hour.
Marissa runs 13,376 feet in 16 minutes. Since 1 mile=5,280 feet:
13,376 / 5,280 = 2.533 miles
16 minutes = 16/60 = 0.2667 hours
Marissa's speed is:
[tex]\displaystyle \frac{2.533\ mile}{0.2667 \ h}=9.5\ mi/h[/tex]
The difference is 15 - 9.5 = 5.5 mi/h
Quincy is 5.5 mi/h faster than Marissa

N
Answer:
2
Step-by-step explanation:
4y = 2x + 8
First get the equation in slope intercept form y= mx+b where m is the slope and b is the y intercept
Divide each side by 4
4y/4 = 2x/4 +8/4
y = 1/2x +2
The slope is 1/2 and the y intercept is 2
Answer:
2
Step-by-step explanation:
Manipulate your equation into slope-intercept form: y = mx + b, where b is the y-intercept.
To do this, divide 4 from both sides:
[tex]y=\frac{1}{2} x+2[/tex]
b = 2
In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?
Answer:
[tex]XY = 4.9[/tex]
Step-by-step explanation:
Given
[tex]XZ= 4[/tex]
[tex]\angle Y = 45[/tex]
[tex]\angle Z = 60[/tex]
Required
Determine the measure of side XY
To do this, we make use of sine law. This is as follows:
[tex]\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}[/tex]
In this case:
[tex]\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}[/tex]
Cross Multiply
[tex]XY * \sin(45) = 4 * \sin(60)[/tex]
[tex]XY * 0.7071 = 4 * 0.8660[/tex]
Make XY the subject
[tex]XY = \frac{4 * 0.8660}{0.7071}[/tex]
[tex]XY = \frac{3.4640}{0.7071}[/tex]
[tex]XY = 4.89888276057[/tex]
[tex]XY = 4.9[/tex] -- approximated
