Find a equation of the line that passes through the points (-2,-5) and (4,25) express the final answer in slope - intercept form. PLEASE HELP IM BEING TIMED
Answer:
y=5x+5
Step-by-step explanation:
to find the slope of the line: 25-(-5)/4-(-2)=30/6=5
so the slope is 5
to find the y-intercept:
y=5x+b
25=5(4)+b (i used the point (4, 25) and plugged in 4 for x and 35 for y)
b=5
so, the equation of the line is: y=5x+5

Answer:
y=60
Step-by-step explanation:
1) Find x
All the interior angles of a triangle add up to 180 degrees. Knowing this, we can construct the following equation:
[tex]180=x+35+25\\180=x+60[/tex]
Subtract 60 from both sides
[tex]180-60=x+60-60\\120=x[/tex]
2) Find y
A straight line has an angle measure of 180 degrees as well. Knowing this, we can construct the following equation:
[tex]180=x+y\\180=120+y[/tex]
Subtract 120 from both sides of the equation
[tex]180-120=y+120-120\\60=y[/tex]
There is also a second way to solve for y: An exterior angle of a triangle is equal to the sum of the opposite interior angles. y, in this case, would be the exterior angle and 35 and 25 degrees would measure the opposite interior angles. To solve for y, we just add 35 and 25, getting us 60 degrees.

Step-by-step explanation:
A dairy farmer delivered milk over two days.
On Monday, he used 5 gallons of fuel to drive 40 miles.
• On Tuesday, he drove 120 miles at an average rate of 10 miles per gallon of fuel.
Determine the miles traveled per gallon of fuel on Monday and the number of gallons of fuel used on
Tuesday,
Answer:
the ans is
Step-by-step explanation:
monday = 40/per gallon
tuesday = 120/per gallon
1) The miles traveled per gallon of fuel on Monday = 4 miles/gallons
2) The number of gallons of fuel used on Tuesday = 12 gallons
What is ratio?"It is a quotient of two mathematical expressions."
What is average rate?"The average rate is the total change in output values divided by the change in the input values."
For given situation,
On Monday,
a dairy farmer used 5 gallons of fuel to drive 40 miles.
So, the miles traveled per gallon of fuel would be the ratio of the distance he drove and the fuel used.
the miles traveled per gallon of fuel:
= 20 / 5
= 4 miles/gallon
Therefore, the miles traveled per gallon of fuel on Monday = 4 miles/gallons
On Tuesday,
he drove 120 miles at an average rate of 10 miles per gallon of fuel.
Let he used 'x' gallons of fuel.
⇒ 10 = 120/x
⇒ 10 × (x) = 120
⇒ x = 120/10
⇒ x = 12 gallons
Therefore, he used 12 gallons of fuel on Tuesday.

Noah has 102 inches of border for poster board. He uses 7 feet of the border. How much border is left
Answer:
The answer is 18.
Step-by-step explanation:
You take 7x12 which is 84 and then you take 84 and subtract it from 102 inches so 102-84=18.
Hope this helps!
Noah after using 7 feet of the border is now left with 95 feet of the boarder.
What are some alternative names for arithmetic operations?Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.
We also know about some basic properties of arithmetics,
There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, Noah has 102 inches of the border for poster board and he uses 7 feet of the border.
Therefore, The amount of border left can be obtained by subtracting the length used from the total length which is,
= (102 - 7) feet.
= 95 feet.

Answer:
x + 2, x ≠ -2
Step-by-step explanation:
Note that F(x) = x^2 + 4x + 4 factors into (x + 2)^2, and that we are dividing this by g(x) = x + 2. The quotient is x + 2, which in this problem has been named h(x).
The quotient (f/g)(x) is therefore x + 2 EXCEPT that this is not defined at x = -2, because the denominator, x + 2, will be zero there, undefined.

The equation of the line shown in the graph is y = 3x + 3.
What is the equation of line?The equation of the line shown in the graph is determined by calculating the slope and y - intercept of the line as shown below.
The slope of the line is calculated as follows;
m = Δy / Δx
where;
Δy is change in y valuesΔx is the change in x valuesm = ( 9 - 3 ) / (2 - 0 )
m = 6 / 2
m = 3
The y - intercept of the line is the point where the line intersects y-axis.
c = 3
The general equation of a line is given as;
y = mx + c
So our equation of the line becomes;
y = 3x + 3

Answer:
a) y = 3x-1
b) y = x+5
Step-by-step explanation:
a) We notice the x-values change by 1, so the change in the y-value is the slope. -4 -(-7) = 3 is the change between the first two y-values.
The y-intercept is shown by the ordered pair (0, -1). So, the slope-intercept equation is ...
y = 3x -1
__
b) We note that the change in x is 2 units, as is the change in y. Then the slope of the function is m = 2/2 = 1. The y-intercept (b) can be found from ...
b = y -mx
b = 7 -1·2 = 5
Then the slope-intercept equation is ...
y = x + 5

Suppose that two high school students decide to see if they get the same results as the
researcher. They both do 30 minutes of aerobic exercise and, immediately following the
exercise, take the test. The mean of their scores is = 25.2 seconds, the same as that of the
publication article. It is appropriate to conclude which of the following?
Complete question is;
A researcher wishes to determine if aerobic exercise improves mental performance immediately following the exercise. He plans to have high school students participate in 30 minutes of aerobic exercise and then take a standard test of their reasoning skills. Suppose the scores of high school students on this test of reasoning skills immediately after 30 minutes of aerobic exercise follow a Normal distribution with mean μ and standard deviation σ = 4. Suppose also that, in the general population of all high school students, scores on the test of reasoning skills follow a Normal distribution with mean 25 and standard deviation σ = 4. The researcher, therefore, decides to test the following hypotheses.
H0 : μ = 25, Ha : μ > 25
To do so, the researcher has 10,000 high school students do 30 minutes of aerobic exercise and then, immediately following the exercise, take the test. The mean score for these students is = 25.2 and the P-value is less than 0.0001.
It is appropriate to conclude which of the following?
Select one:
A. The researcher has conclusively proved that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.
B. The researcher has strong evidence that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.
C. The researcher has moderate evidence that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.
D. None of the above
Answer:
D. None of the above
Step-by-step explanation:
We see that the researcher wants to test the hypotheses;
Null hypothesis; H0 : μ = 25,
Alternative hypothesis; Ha : μ > 25
Population mean = 25 and standard deviation σ = 4
After testing a sample of 1000 students, he discovered that;
Sample size; n = 1000
Sample mean; x¯ = 25.2
After calculations, he got P-value as less than 0.0001.
Now, he can't make any conclusion or evidence for this research because there is no population mean for the aerobic exercise and also no significance value in the entire question to compare the p-value with.
Thus, none of the options are correct.
A gumball machine consists of a base and a glass sphere. The gumballs are stored in the glass sphere. If each
gumball has a diameter of 1.5 inches, about how many gumballs can be stored in a gumball machine whose glass
sphere measures 10 inches in diameter?
Answer:
6 gumballs can be stored in the gumball machine.
Step-by-step explanation:
Since a gumball machine consists of a base and a glass sphere, and the gumballs are stored in the glass sphere, if each gumball has a diameter of 1.5 inches, to determine how many gumballs can be stored in a gumball machine whose glass sphere measures 10 inches in diameter, the following calculation must be made:
10 / 1.5 = X
6.666666 = X
Thus, 6 gumballs can be stored in the gumball machine.
