Write the equation of the line, in general form, that has a slope of 3 and a y-intercept of -5.
Answer:
y = 3x - 5
Step-by-step explanation:
To find the equation of the line, you can use y = m x + c.
Here,
m ⇒ slope
c ⇒ y-intercept
Given that,
slope = 3
y-intercept = -5
So, to find the equation of the line you have to simply replace m and c in the formula, (y = m x + c )with the given slope and y-intercept.
Let us solve it now.
y = m x + c
y = 3x - 5
Answer:
y = 3x - 5
Step-by-step explanation:
Slope-intercept form of an equation
y = mx + bm = slopeb = y-interceptGiven that m = 3 and b = -5

Answer:
mode = 6
range = 7
Step-by-step explanation:
To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.
Frazer scores 70% in a spelling test. If there are 40 spellings, how many did he get right?
The number of the correct spellings is 28.
What are percentages?The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
Given that:-
Frazer scores 70% on a spelling test. If there are 40 spellings,The number of the spellings are:-
N = 40 x 70% = 28
N = 40 x (70/100) = 28

Mr. Ortega bought his home for $242,800. It is
predicted to appreciate in value by 4.5% each
year. Which is the best prediction for the value
of Mr. Ortega's home in 15 years?
A. $406,690
B. $469,887
C. $1,092,600
D. $1,638,900
Answer:
$469887
Step-by-step explanation:
you should use compound interest formula which is
A=P(1+r/100) ^t
A = 242800 ( 1 + 0.045 ) ^ 15
when you punch this into a calculator you will get 469886.5771.....
when you round it off to a whole number the answer is $469887
In degrees what is the measure of MFE
There's a lot going on in this problem, but I think I know how to solve it. So let's first address the fact that opposite angles are equal.
Let's also address the fact that (x + 6) + (3x - 4) add up to equal 90. So with that information, we can write a problem.
x + 6 + 3x - 4 = 90
Add the x's.
4x + 6 - 4 = 90
Combine the 6 and 4.
4x + 2 = 90
Subtract the two on both sides.
4x = 88
Finally, divide by 4.
x = 22
But by no means are we done yet. We still have to find out the entire angle MFE's measure, so we'll substitute 22, our new x value, into the equation for MFE - (x + 6)
22 + 6 is the new equation.
22 + 6 = 28
Angle MFE is 28°. I took the liberty of solving for the other angle, too, so I could check the answer. And as of my checking, this answer is correct because
62 + 28 = 90
I hope this answers your question.

4. A jeep can travel 356 miles in 6 hours, and a truck can travel 221 miles in 3.5 hours. What is the unit rate of the faster vehicle? Round your answer to the nearest hundredth.
Answer:
63.14
Step-by-step explanation:
in order to get unit rate you take the distance 221miles divide by time which is 3.5 hr you get 63.14 after you have rounded .when you take 356miles divide by 6hrs you get 56.33 so the vehicle is the truck i think so

What is the experimental probability of rolling a number less than 4?
A: 1/2
B: 16/33
C: 1/22 D: 17/33
what is the answer?
HELP
Answer:
A. 1/2
Step-by-step explanation:
For the question, it says what is the experimental probability of rolling a number less than 4, meaning it is asking for the experimental probability of rolling a 1, 2, or 3. Assuming this is a fair 6-sided dice, the probability of rolling any number is 1/6. The probability of rolling a 1, 2, or 3 is also 1/6. Adding all those the probabilities of 1, 2, and 3 together gets 3/6, which simplifies to 1/2.
Therefore, the experimental probability of rolling a number less than 4 is 1/2.

3 x 2/3 + 1/5 x 2/332/152 2/15.What is Fraction?Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.
The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.As, the length of the painted area is 3 1/5 and width of the painted area is 2/3.
So, multiplication of length and width is as follows:
3 1/5 x 2/3
= 3 x 2/3 + 1/5 x 2/3
= 6/3 + 2 / 15
= 30 + 2 / 15
= 32/ 15
= 2 2/15
Thus, the required fraction is 2 2/15.
