Answer:
C
Step-by-step explanation:
the typical form of line equation is
y = ax + b
a = the slope of the line (expressed as y/x ratio telling us how many units y changes when x changes a certain number of units).
b = the intercept on the y-axis (when x = 0).
we know, a = -4
and we use the point (x = -2, y = 1) to get b
y = -4x + b
1 = -4×-2 + b = 8 + b
b = -7
=>
y = -4x - 7
only the points of option C are all fulfilling this equation.
e.g. x = 0, y = -7
-7 = -4×0 - 7 = -7, true, -7 = -7
and so on.

Answer:
The integers are

14 +3n = 8n - 3(n - 4)
Answer:
n=1
Step-by-step explanation:
Start by distributing the -3 to (n-4)
14+3n=8n-3n+12
Then combine like terms on the right
14+3n=5n+12
Subtract 12 from both sides
2+3n=5n
Subtract 3n from both sides
2=2n
Divide both sides by 2

Find the x-intercept and y-intercept of the line.
4x+5y= -20
Answer:y-intercept = -20/5 = -4 x-intercept = -20/4 = -5
Step-by-step explanation:
Answer:
x- intercept = - 5, y- intercept = - 4
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis.
The y- coordinate of any point on the x- axis is zero
Substitute y = 0 into the equation and solve for x
4x + 5(0) = - 20
4x = - 20 ( divide both sides by 4 )
x = - 5 ← x- intercept or (- 5, 0 ) in coordinate form
The y- intercept is where the line crosses the y- axis
The x- coordinate of any point on the y- axis is zero
Substitute x = 0 into the equation and solve for y
4(0) + 5y = - 20
5y = - 20 ( divide both sides by 5 )
y = - 4 ← y- intercept or (0, - 4 ) in coordinate form

help me with my homework
Answer:
a because I dont know why but some one told me it was this
Answer: A. There are three terms
Concept:
In an algebraic expression, there are several specific terms:
Constant: the individual number that has no variable with it, or in east word, it is isolated.Variable: any unknown value, which is usually presented by alphabets.Coefficients: the numbers that are bounded with a variable, usually in front of a variable.Terms: the number of individuals present in the expression, which is constants and [variable + coefficients].Like terms: terms that have the same variables and powers.If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
a. There are three terms. [tex]\boxed{FALSE}[/tex]
- 14b
- -7
- 8b
- b
There are in total four individuals, which means there are four terms.
b. There is one constant term. [tex]\boxed{TRUE}[/tex]
- 14b is a [variable + coefficient]
- -7 is a [constant]
- 8b is a [variable + coefficient]
- b is a [variable]
Therefore, there is one constant term.
c. The coefficients are 14, 8, and 1 [tex]\boxed{TRUE}[/tex]
- 14b →→→ 14 is the [coefficient]
- -7 →→→ is a [constant]
- 8b →→→ 8 is the [coefficient]
- b →→→ 1 is the [coefficient]
Therefore, 14, 8, and 1 are coefficients.
d. Three of the terms are like terms [tex]\boxed{TRUE}[/tex]
- 14b →→→ b is the [variable]
- -7 →→→ is a [constant]
- 8b →→→ b is the [variable]
- b →→→ b is the [variable]
Since 14b, 8b, and b share the common variable, there are three like terms.
Hope this helps!! :)

A phone call costs $0.65 for the first 3 minutes and $0.15 for each additional minute. If the total charge for the call
was $5.00, how many minutes was the call?
Answer:
31 Minutes
Step-by-step explanation:
4.78 = 0.15 + 0.58
0.15m = 4.78 - 0.58
m = 4.78 - 0.58 divided by 0.15 = 28 minutes
So in total we have 28 + 3 = 31 minutes
The sum of the angle measures of a quadrilateral is 360 degree . Write and solve an equation to find the value of x .
A quadrilateral with interior angles marked as x degrees, 150 degrees, 77 degrees, and 48 degrees.
The equation is
360= .
x=
Answer:
Step-by-step explanation:
The value of the angle x is 85°
The sum of angles of a quadrilateral = 360°
This means that given a quadrilateral with angles, A, B, C, D ;
(A + B + C + D) = 360°
Given the angles of a quadrilateral : (x°, 150°, 77°, 48°)
The value of x will be obtained thus :
(x + 150 + 77 + 48) = 360
150 + 77 + 48 + x = 360
275 + x = 360
x = 360 - 275
x = 85°
Hence, the value of x is 85°

Answer:
17
Step-by-step explanation:
Answer:
x = 17
Step-by-step explanation:
We can find the missing angle inside the triangle by doing 180 - 94 = 86.
Every triangle has 3 angles that add up to equal 180 so we can set these three angles to equal 180.
60 + 86 + 2x = 180
146 + 2x = 180
Subtract 146 from both sides
2x = 34
Divide by 2 to isolate x
x = 17

An insurance company sells a homeowner's insurance policy that is $600 per year per policy. The insurance company predicts that the probability of having a home being damaged in the area it sells this policy is about 11,000. If the home is damaged, the insurance company expects to pay $400,000 to the homeowner. If the company were to sell 250 policies, how much money can it expect to gain or lose
Answer:
profit of $140,910
there is a missing number I will assume that the probability is 1 in 11,000
company expected revenue per policy = $600
companies expected expense = 400,000 * (1/11,000) = -36.36
profit per policy = $536.64
$536.64*250 = $140,910

please help!!! i cant figure it out
Step-by-step explanation:
Hi there!
Given;
f(x) = 17x + 9
h(x) = 4x
To find: f(x)-h(x)
f(x)-h(x)= 17x + 9 - 4x
= 13x + 9
Therefore, f(x)-h(x) = 13x + 9.

The equation y=0.5x simply means that Joseph is hiking 0.5 miles every hour. This is because the x value is the independent variable or the thing you change, which in this case is the time you take hiking. The distance, the y-value, is dependent on that time.
Now, let's look at Kelly's graph. This graph isn't a grid, so we will have to eyeball some of the numbers on the graph. It appears that after 10 hours, Kelly has traveled eight miles. This is because if you go up from the 10 and meet the line and then go to the left. you will be about at the line right below the 10 on the y-axis, and if you count the lines, you will see that we are counting by 2, so it has to be eight.
So, we see that Kelly takes 10 hours to go eight miles. We know that Joseph's distance is half of his time (4 hours would be 2 miles, 6 hours would be 3 hours, etc.)
So, if we say that Joseph hikes for ten hours, he will have hiked five miles as that is half of ten. We see, though, that Kelly made it eight hours in that time, so Kelly is going faster here.

Answer:
quadrilateral has 4 sides
so 104°+40°+110°+x=360°
254°+x=360°
collect like terms
x=360-254
x= 106
;- x=106
which is (c)
Answer:
x = 106°
Step-by-step explanation:
Using the angle marked 110° as my starting point,
One can use angles on a straight line sum up to 180° to find the angle that adds up to 110° which makes it 180,
thus 70°.
moving on,
tackling with the angle marked 40°, Using the fact that angles on a straight line sum up to 180°, the angle obtained will be 140° (40° + a = 180, a = 180° -40°, a = 140°)
Using the angle marked 104°, Just like the previous one Using the principle that angles on a straight line sums up to 180°, then the unknown angle will be 76°.
Finding all the other interior angles angles in the quadrilateral except the angle in line with the x,
the next step to take is to add up all the angles Using any variable and equate it to 360°
why? angles in this type of quadrilateral equals 360,
That is,
140° + 76° + 70° + y = 360
286 + y= 360
y = 360 - 286
y = 74
The final step now is to use the principle, ( angles on a straight line sums up to 180)
74° + x = 180
x = 180 - 74
x = 106°
