Answer:

Step-by-step explanation:
Let's break this inequality into two parts:
3 < 3x - 1 ← Inequality I3x - 1 < 2x + 6 ← Inequality IISolve Inequality I.
3 < 3x - 1Add 1 to both sides.
4 < 3xDivide both sides by 3.
4/3 < xSolve Inequality II.
3x - 1 < 2x + 6Subtract 2x from both sides.
x - 1 < 6Add 1 to both sides.
x < 7Combine these two inequality solutions.
4/3 < x < 7Integer solutions to this inequality would be any integer between 1 (4/3 = 1.3...) and 7, exclusive.
These five numbers are 2, 3, 4, 5, 6.

50 – 5(4.3 – 1.3) ÷ 0.5
Answer:
(0.5, 1.3)(0.5, 1.3)
Step-by-step explanation:
Given equations are:
As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.
We can plot the graph of both equations using any online or desktop graphing tool.
We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)
We can see from the graph that the lines intersect at: (0.517, 1.267)
Rounding off both coordinates of point of intersection to nearest tenth we get
(0.5, 1.3)
Hence,
(0.5, 1.3) is the correct answer

What is a complex number?Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The idea of a complex number has come by solving a quadratic equation that has root as negative under root.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
Given points, x,y, and z in a complex plan where an x-axis is a real number and the y-axis is an imaginary (i.e. i ) number.
So,
Point x is 3 units to the negative side and 2 units up so its coordinate will be (-3, 2i) so -3 + 2i.
Point w is 4 units to the positive side and 0 units up so its coordinate will be (4,0i) so 4 + 0i.
Point z is 4 units downside so its coordinate will be (0,-4i) so 0 + -4i.

The highest recorded temperature in the world was at Azizia, Libya, on September 13, 1922. The temperature was 58.0°C. The lowest temperature, -88.3°C, was recorded at the Soviet Antarctic station Vostok on August 24, 1960. What is the difference in these two temperatures?
Answer:
the difference in these two temperatures is 146.3°C
Step-by-step explanation:
The computation of the difference in these two temperatures is as follows:
= Highest temperature - lowest temperature
= 58.0°C - (-88.3°C)
= 58.0°C + 88.3°C
= 146.3°C
Hence, the difference in these two temperatures is 146.3°C
It is determined by the applying the above formula and the same is relevant

Last night, the temperature fell from 0°F to -13 in 4 § hours. What was the average temperature change per hour? Solve the division problem. 2 1 -13= - 4 5 5 The temperature drop per hour can be represented by I °F. QUICKLY
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]
So, the change in temperature is 3.25 degrees/hour.
Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25

slope intercept
Answer:
y=4/3x+2
Step-by-step explanation:
The equation is in standard form right now, which is ax+by=c
your question is asking for slope intercept form, which is y=mx+b
so we need to isolate y onto 1 side
-4x+3y=6
add 4x to both sides
3y=4x+6
divide by 3 on both sides
y=4/3x+2
