Answer:
y = x - 5
Step-by-step explanation:
Given the point, (10, 5), and the slope, m = 1:
Substitute these values into the slope-intercept form to solve for the y-intercept, b:
y = mx + b
5 = 1(10) + b
5 = 10 + b
Subtract 10 from both sides to isolate b:
5 - 10 = 10 - 10 + b
-5 = b
The y-intercept of the line is: b = -5. This represents the y-coordinate of the y-intercept, (0, -5), which represents the point on the graph where it crosses the y-axis. Along the y-axis, the value of x = 0. Hence, the y-intercept is (0, -5).
Therefore, given the slope, m = 1, and the y-intercept, b = -5:
The equation of the line in slope-intercept form is: y = x - 5.
Find the missing angle
Answer:
x=33
Step-by-step explanation:
The sum of the angles of a triangle is 180
23+124+x = 180
147+x =180
x = 180-147
x =33
Answer: 33
Step-by-step explanation:
A triangle is equal to 180 degrees. So you add 124 and 23 to get 147. You would then subtract 180-147=33 and then you have your answer. Hope this helps!
If f(x) = x2 + 5, find f(-9).
Answer:
f(-9) = 86
Step-by-step explanation:
Hi there!
f(x) = x² + 5
To find f(-9), replace x with -9:
f(-9) = (-9)² + 5
f(-9) = 81 + 5
f(-9) = 86
I hope this helps!

g(x) = 2x^2
for g(- 4), you just plug in - 4 for x
g(- 4) = 2(- 4)^2
g(- 4) = 2(16)
g(- 4) = 32
Answer:
g(-4) = 32
Step-by-step explanation:
Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.
Solution:g(x) = 2x²
g(-4) = 2(-4)² = 2(-4)(-4)
g(-4) = 2(16)
g(-4) = 32
Therefore, g(-4) = 32.

Anna went to the playground at 4:05 P.M. She played on the slide for 30 minutes and the swings for 55 minutes, then went home. What time was it when Anna left the playground?
Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
Answer:
5:30 P.M.
Step-by-step explanation:
30 (slide) minutes and 55 (swings) minutes. These numbers (time-wise) total up to an hour and 25 minutes. Adding this to 4:05 P.M. would mean that she left the playground at 5:30 P.M.
Hope this helps.

Pre college which is correct
Answer:
x = 7 and y = -8 ordered pair is (7, -8)
Step-by-step explanation:
0.1x + 0.3y = - 1.7
0.3x - 0.5y = 6.1
Solving the first equation for x 0.1x = -0.3y - 1.7
0.1x/0.1 = -0.3y/0.1 - 1.7/0.1
x = -3y - 17
Substitute into the second equation.
0.3(-3y - 17) - 0.5y = 6.1
-0.9y - 5.1 - 0.5y = 6.1
-1.4y - 5.1 = 6.1
-1.4y = 5.1 + 6.1
-1.4y = 11.2
y = 11.2/-1.4
y = -8
Substitute y into the first equation and solve for x
x = -3y - 17
x = -3(-8) - 17
x = 24 - 17
x = 7

Amy graphed a point to represent the absolute value of a number on a number line. If the original number is less than −10, describe all the possible values for the point Amy graphed on the number line.
Answer:
x>= 11 or x>10
Step-by-step explanation:
Absolute value can be used to represent the positive counterpart of a negative number. In this case, we are asked to find a number that is less than -10, meaning from -11 to negative infinity. Since we are asked to take absolute value, we would take |-11| which equals 11, and |-∞| = ∞.
So Amy graphed a value on the number line that is greater than or equal to 11, or any value greater than 10.
*Infinity is not a real number, it represents the largest number possible, which doesn't exist since numbers can continue on forever, so it can be disregarded.*

if a 1x1 foot tile costs 3.50 each ,how much will it cost mr teal?
Answer:
Hope this helps.
Step-by-step explanation:
When measuring for floor tile the rule is:
Length x Width + Waste = Amount Needed
Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Step-by-step explanation:
As you have noticed, the difference between the end values of x is 20-4 = 16, and the differences in each interval are 4.
The difference between the end values of y is 12 -(-4) = 16, so the differences in each interval will also be 4.

A population of values has a normal distribution with
μ
=
124.9
and
σ
=
45
. You intend to draw a random sample of 36 items from this population.
Find the probability that the mean of this sample is less than 105.4.
The probability that the mean of this sample is less than 105.4 is 14.46%
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean,n\ is\ sample\ mean\\\\\\Given\ that\ \sigma=45,\mu=124.5,n\ =36,hence:\\\\For\ x<105.4:\\\\z=\frac{105.4-124.9}{45/\sqrt{36} }=-1.06[/tex]
From the normal distribution table, P(x < 105.4) = P(z < -1.06) = 0.1446 = 14.46%
The probability that the mean of this sample is less than 105.4 is 14.46%

Find the rate if a principal of $1,800 earned $378 interest in 6 years
Answer:
Interest rate (r ) = 0.035 or 3.5%
Step-by-step explanation:
Given the principal amount of $1,800, and an interest payment of $378 earned in 6 years:
Use the simple interest formula and algebraically solve for variable, interest rate, r :
I = P × r × t
Where:
I = interest payment = $378
P = principal amount = $1,800
t = time (in years) = 6
r = interest rate
Divide both sides by P × t to isolate r :
[tex]\displaytext\sf{\frac{I}{P\:\times\:t}\:=\:\frac{P\:\times\:r\:\times\:t}{P\:\times\:t}}[/tex]
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{I}{P\:\times\:t}}[/tex]
Substitute the given values into the formula for the interest rate:
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{378}{1800\:\times\:6}\:=\:\frac{378}{10800}}[/tex]
Interest rate (r ) = 0.035 or 3.5%
Therefore, the interest rate is 3.5%.
