How do I graph
y=-1/2x-1
Answers
Answer:
Step-by-step explanation:
Find the x and y intercept, and determine the slope.
X-intercept:
[tex]0=-\frac{1}{2}x-1\\1=-\frac{1}{2}x\\x=-2[/tex]
It crosses the x-axis at x = -2
Y-intercept:
[tex]y=-\frac{1}{2}(0)-1\\y=-1[/tex]
It crosses the y-axis at y = -1
Slope:
y = mx + b
m = slope = -1/2
The graph of the linear equation y = -(1/2)x - 1 is plotted.
Given data:
To graph the equation y = -1/2x - 1, use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
So, the slope is -1/2, and the y-intercept is -1.
To plot the graph, follow these steps:
Plot the y-intercept:
Start by plotting the point (0, -1), which represents the y-intercept.
Use the slope to find another point: Since the slope is -1/2, use the rise and run method. From the y-intercept point (0, -1), move down 1 unit (negative 1) and then move to the right 2 units. This gives another point on the line, which is (2, -2).
Hence, the resulting graph should be a straight line sloping downwards from left to right and is plotted below.

What does b stand for 11.3 > b/4.3
Answers
Answer:
b = 45.69
Step-by-step explanation:
5 x 5 = 25
25 x 2 & and a half = 45.69
In the inequality expression "11.3 > b/4.3," the variable "b" represents an unknown numerical value.
In the inequality 11.3 > b/4.3, b is the variable.
The inequality is stating that 11.3 is greater than the result of dividing "b" by 4.3.
The purpose of the inequality is to compare the value of 11.3 with the value of "b/4.3" and determine if 11.3 is greater or not.
The variable "b" can take any value that satisfies the inequality.
Hence, in the inequality b stands for unknown value or variable.

How much greater is the average temperature on Earth the the average temperature on Jupiter? Jupiter's temperature is -166, Earth's temperature is 59.
Answers
Answer: 107 I think
Step-by-step explanation:
The average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Jupiter's temperature is -166, and Earth's temperature is 59.
We have to find the temperature difference between the earth and Jupiter.
In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
The average temperature on Earth and the average temperature on Jupiter are obtained by applying the subtraction operation as,
Δt= T(earth) - T(jupiter)
Δt=59-(-166)
Δt=59+166
Δt=225 degrees
Thus, the average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

*Hana purchased 2 pairs of pants for $26.59 each and a coat for $49. She used a coupon that saved her $10. The sales tax for the purchase was $7.84. How much was the total purchase?
Answers
Answer:
$100.02
Step-by-step explanation:
*Sales tax is always applied after the discount/coupon
1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 each, we would have to multiply 26.59 by 2. So,
26.59 times 2 is 53.18.
Hana spent $53.18 on pants
2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 each, we would have to multiply 49.00 by 1. So,
49.00 times 1 is 49.
Hanna spent $49 on coats
3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,
53.18+49=102.18
Hanna spent $102.18 on clothes
4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana save $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,
102.18-10=92.18
Hanna "spent" $92.18 on clothes after using the coupon
5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be added to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,
7.84+92.18=100.02
The total purchase is $100.02

Use the Pythagorean Theorem to figure out which triangle is NOT a right triangle. Square each leg and add them together. Then, square the hypotenuse (longest side). If the sums are equal, then the triangle IS a right triangle.
Pythagorean Theorem:
a(a) + b(b) = c(c) ; a squared plus b squared equals c squared
6(6) + 24(24) =? 26(26) ; leg a =6, leg b=24, hypotenuse=26

I doing vertical angles and I'm way too confused to even understand
Answers
Erotically angles are opposite each other and equal the same degree.
In the image 5x and 120 are vertical angles so 5x needs to equal 120.
X = 120/5
X = 24
Answer:
X=24 degrees.
Step-by-step explanation:
120/5=24. You divide by 5, because the angles will be congruent, and the top angle is 5*_=120. And 5*24=120, so x=24

Quotient of 59.4 and 8.25 show work
Answers
Answer:
in previous material it was shown that the digit sum of the product of two integers is equal to the digit sum of the product of the digit ... For instance, 66/8 = 8.25. ... For example, 35/7=5; the digit sum of the quotient is 5 and the digit sum of 35 is 8.
Missing: 59.4 | Must include: 59.4
Answer:
7.2
Step-by-step explanation:
Change the divisor 8.25 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
5940 ÷ 825 = 7.200
and therefore:
59.4 ÷ 8.25 = 7.200
Both calculated to 3 decimal places.
