19) Geoff owns a computer store in 1990 he sold 2400 monitors and in 2000 he sold 4000. Let x
represent the number of years since 1990. Write a linear equation in slope intercept form that
represents this data.
Answer:
B. [tex] y = 160x + 2400 [/tex]
Step-by-step explanation:
The linear equation for that represents the above data is given in slope-intercept form as [tex] y = mx + b [/tex], where:
m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
b = starting value = y-intercept = 2,400
Slope of the linear equation using (0, 2400) and (10, 4000):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4000 - 2400}{10 - 0} = \frac{1600}{10} = 160 [/tex]
Substitute m = 160, and b = 2,400 in [tex] y = mx + b [/tex].
Thus, the linear equation in slope-intercept form would be:
✅[tex] y = 160x + 2400 [/tex]
Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).
Answer:
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 + (-8) + 6
= -1 + 6
= 5

Answer:
A) 10/3
Step-by-step explanation:
substitute the y statement into the x statement and solve regularly.
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50
x = 10/3

Which of the following is a solution to the system? Show your work.
3x+2y=-3
3x-y=6
Group of answer choices
(-1, 0)
(1, -3)
(2, 0)
LaTeX: (0,-\frac{3}{2})
Answer:
(1, -3) is a solution to the system of equations ⇒ B
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + 2y = -3 ⇒ (1)
∵ 3x - y = 6 ⇒ (2)
→ Subtract equation (2) from equation (1)
∵ (3x - 3x) + (2y - -y) = (-3 - 6)
∴ (0) + (2y + y) = (-9)
∴ 3y = -9
→ Divide both sides by 3 to find y
∴ y = -3
→ Substitute the value of y in equation (2) to find x
∵ 3x - (-3) = 6
∴ 3x + 3 = 6
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = 6 - 3
∴ 3x = 3
→ Divide both sides by 3 to find x
∴ x = 1
To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right
∵ 3x + 2y = -3
∵ 3(1) + 2(-3) = -3
∴ 3 - 6 = -3
∴ -3 = -3
→ The two sides of the equation are equal
∵ 3x - y = 6
∵ 3(1) - (-3) = 6
∴ 3 + 3 = 6
∴ 6 = 6
→ The two sides of the equation are equal
∴ The solution satisfies the two equations
∴ (1, -3) is a solution to the system

What number would you multiply the 2nd equation by in order to eliminate the y terms?
4x - 4y = 16
2x + y = 5
Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3
Select all the measurements that are equivalent to 2.4 meters.
0.0024 km

240 cm
2,400 mm
Answer: (A)0.0024 Km (D) 240 cm, (E) 2,400 mm... Hope it helps, have a great day!
Step-by-step explanation:
The measurements that are equivalent to 2.4 meters are
0.0024km, 240cm and 2400mm.
The correct options are (A), (D) and (E).
What is unit conversion?Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor.
A unit conversion expresses the same property as a different unit of measurement.
For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
Given,
measurement = 2.4 meters
1 meter = 1/1000 km
⇒ 2.4 meter = 2.4 /1000 = 0.0024 km
1 meter = 100 cm
⇒ 2.4 meters = 2.4×100 = 240 cm
1 meter = 1000 mm
⇒ 2.4 meters = 2.4×1000 = 2400 mm
Hence, 0.0024km, 240cm and 2400mm are the measurements that are equivalent to 2.4 meters.
