Answer:
y= -1/3x - 5
Step-by-step explanation:
Answer:
The answer would be y=-1/3x-7.
Step-by-step explanation:
Using the formula y2-y1/x2-x1 to find the slope of the line, plug in the numbers and you will get a slope of -1/3. Now using the the formula y-y1=m(x-x1) and plug in the numbers, and you will get the equation y=-1/3x-7.
Solve each system of equations algebraically. For each one, explain what the solution (or lack thereof) tells you
about the graph of the system.
Solve A and B
PLEASE HELP ASAP!!!
Answer:
a: no solutions
b: (2, 3)
Step-by-step explanation:
a:
In both equations, the slope of x is the same, but the y-intercept is not, which means they are parallel. Therefore, this system of equations has no solutions.
b:
Since both of the equations are equal to y, we can set them equal to each other:
[tex]\frac{1}{2}x^2+1= 2x-1\\x^2 + 2 = 4x - 2\\x^2-4x+4=0[/tex]
We can solve by factoring (by finding a number that multiplies to 4 and adds up to -4):
(x-2)^2 = 0
x = 2
Now, to find y, plug-in x to any of the equations:
y = 2*2-1 = 3
Therefore, the solution to this system of equation is (2, 3)

5 2/5 as a mixed number
Answer:
Mixed numbers have a whole number followed by the fraction (2 1/2). You would say "two and one half." The other format is an improper fraction where the numerator is greater than the denominator (5/2). Mathematicians would say that is five halves.

The tank for a car holds 17 gallons. The gasoline gauge shows the tank is 1/4
full. How much gas is still in the tank? Give your answer as a whole number or as a mixed fraction reduced to the lowest terms.
Answer:
4 1/4 gallons
Step-by-step explanation:
The amount of gas in the tank is 1/4 of 17 gallons.
1/4 * 17 gallons = 0.25 * 17 gallons = 4.25 gallons = 4 1/4 gallons
4 1/4 or 17/4
What is a mixed fraction?
A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.
Step 1: Multiply the denominator with the whole number. Step 2: Add the numerator to the product obtained from step 1. Step 3: Write the mixed fraction with the sum obtained from step 2 as the numerator and the denominator of the original fractional part of the mixed fraction.
Given,
Full tank capacity = 17 gallons
gasoline gauge shows = 1/4 of full tank
= 1/4 of 17 gallons
= 17/4 gallons
= 4 1/4 gallons

1. A pitched roof is built with a 1:3 ratio of rise to span. If the rise of the roof is 10 meters, what is the span
Answer:
The answer is B) the span of the roof is 4
Step-by-step explanation:
The span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
A pitched roof is built with a 1:3 ratio of rise to span
rise/span = 1/3
rise = 10 meters
10/span = 1/3
span = 3×10 = 30 meters
Thus, the span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.

Step-by-step explanation:
-2 1/3= -7/3
-5=-15/3
Answer:
If I'm reading this correctly, -2.33 or -2 1/3 - (-5) should equal to 2 2/3
Step-by-step explanation:
Since a minus sign is close to the minus sign inside the parantheses, you should turn the minus sign into a plus, giving you -2 1/3 + 5 which should equal to 2 2/3. Hope this helps

Meandre has 8 pints of milk. If he drinks ¼ of a pint of milk each day, how long will the 8 pints of milk last him?
Answer:
16 days
Step-by-step explanation:
1/4 = 0.25
8 divied 32
In multiplacation
8 time 4 = 32
8 pints of milk will last for 32 days.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given that,
Total amount of milk Meandre has = 8 pints
Amount of milk drinking in 1 day = 1/4 pint
We have to calculate the number of days that 8 pints of milk will last.
Let x be the required number of days.
Using the concept of proportion,
(1/4) / 1 = 8 / x
1/4 = 8 / x
x = 8 × 4
x = 32
Hence total number of days that 8 pints of milk will last is 32 days.
