Answer:
(7,2)
Step-by-step explanation:
Multiply the first equation by -3
(x-3y=1) = -3x+9y=-3
Combine like terms with the new equation and the second equation
(-3x+9y=-3) + (3x-5y=11) = 4y=8
Divide each side by 4
4y/4=8/4
y=2
Plug in 2 for y in any equation. It doesn’t matter which one
x-3(2)=1
Distribute
x-6=1
Add 6 to both sides
x-6=1
+6 +6
x=7
Answer: x = 7 y = 2
(7, 2)
Step-by-step explanation:
Multiply the first equation by -3 and the second by 1:
-3(x - 3y = 1)
1(3x - 5y = 11)
Becomes:
-3x + 9y = -3
3x - 5y = 11
Add the equations to eliminate x:
-3x + 9y = -3
3x - 5y = 11
4y = 8
Solve for y by dividing by 4:
4y/4 = 8/4
y = 2
Now we plug in y to the first equation:
x - 3 ( 2 ) = 1
x - 6 = 1
Add 6 to both sides:
x - 6 + 6 = 1 + 6
x = 7
elimination method
x-5=-y
3x-10=2y
Answer:
(4,1)
Step-by-step explanation:
Multiply the first equation by -3
(x-5=-y)*-3 = -3x+15=3y
Then combine like terms with the new equation and the second equation
(-3x+15=3y) + (3x-10=2y) = 5=5y
Divide 5 by both sides
1=y
Plug in 1 for y in an equation. Doesn’t matter which one and solve
x-5=-(1)
Distribute the negative sign to the 1
x-5=-1
Add 5 to both sides
x=4
The volume of a gas was measured as
its temperature was increased from 10°K
to 15°K at intervals of 1°K. The volumes
were 1.5, 2.2, 3.38, 5.1, and 7.6 cm.
Would a linear or exponential function
better approximate the data described?

need help with questions 15 and 16 please
Answer:
#15: y = -5x -4
#16: y = 2/5x -4
Step-by-step explanation:
Lets start with #15:
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx -4
Pick another point and substitute its x and y values in this equation.
I chose (-1,1) and substituted as 1 = m(-1) -4
Isolate m:
1 + 4 = -m - 4 + 4
5 = -m
m = -5
The Equation in Slope Intercept Form is y = -5x -4
Let's do #16.
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx - 4
Pick another point and substitute its x and y values in this equation.
I used Fractional Points as Whole ones were not seen.
I chose (5/2,-3) and substituted as -3 = m(5/2) - 4
Isolate m:
-3 + 4 = 5m/2 - 4 + 4
1= 5m/2
m=2/5
The Equation in Slope Intercept Form is y = 2/5x - 4

20 Points!!! Math Question
Here is how to do the question,
The Remainder Theorem starts with an unnamed polynomial p(x), where "p(x)" just means "some polynomial p whose variable is x". ... If you get a remainder, you do the multiplication and then add the remainder back in. For instance, since 13 ÷ 5 = 2 R 3, then 13 = 5 × 2 + 3. This process works the same way with polynomials.
Hope that helps!!!!

Which statement is true about the following pair of rectangles?
Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.
Answer:
Option D
Step-by-step explanation:
the height of the first rectangle ( 30 ) over the height of the other rectangle ( 3 ) is 30/3 and equals 10
the length of the first rectangle ( 60 ) over the length of the second rectangle ( 6 ) is 60/6 and equals 10
the ratio of the sides of both rectangles are equivalent therefore the are similar

E. 3
Answer: A
Step-by-step explanation:
Treat the real and imaginary parts separately, then combine. Because it is addition, not subtraction, distributing the sign will not make a difference. Remove the parenthesis and group like terms together. Then simplify and put in standard form for imaginary numbers (real first, then imaginary).

What is the measure of the missing angle
Answer:
41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let x be the missing angle, then sum the angles and equate to 180°, that is
87° + 52° + x = 180°
139° + x = 180° ( subtract 139° from both sides )
x = 41°

Area of sector ≈ 15.6π (nearest tenth)
Step-by-step explanation:
Given:
radius = 5 cm
Central angle in radians = ∅ = 5π/4
Required:
Area of the sector
Solution:
Area of sector = ½*r²*∅
Plug in the values into the formula
Area of sector = ½*5²*5π/4
= ½*25*5π/4
= 12.5*5π/4
= (12.5*5π)/4
Area of sector = 15.625π ≈ 15.6π (nearest tenth)

A driver travels 288 miles in 6 hours. What is the driver’s speed, in miles per hour? Is it 48? I got 48
Answer:
48
Step-by-step explanation:
288 divided by 6 is 48 and how you get mph is todal miles in 1 hr
The speed of the driver for the entire journey is 48 miles per hour.
The given parameters;
distance traveled by the driver, d = 288 milestime of motion, t = 6 hoursSpeed is defined as the ratio of total distance traveled by the total time of motion.
The speed of the driver for the entire journey is calculated as follows;
[tex]speed = \frac{distance}{time} \\\\speed = \frac{288 \ miles}{6 \ hours} \\\\speed = 48 \ miles \ per \ hour[/tex]
Thus, the speed of the driver for the entire journey is 48 miles per hour.
