Write equation in slope intercept form (x=mx+b). Find the slope (x) and the y-intercept (b) of the line
Answer:
y = (2/3)x - 1
Step-by-step explanation:
By refering the graph, we can see that y-intercept(b) = (a point of the y-axis) which is -1.
the coordiates i have taken:
(-3 , -3) ------ (-3 =x1, -3 =y1)
and
( 3, 1 ) --------( 3 = x2, 1 = y2)
To find slope,
slope(m) = rise/run = ( y2 - y1 ) / ( x1 - x2 )
=> ( 1 - (-3) ) / ( 3 - (-3) ) -----( negative × negative = positive. Hence the signs are positive. )
=> ( 1 + 3 ) / ( 3 + 3 )
=> 4 / 6
=> 2 / 3 ------(simplied after numerator and denominator got divided by 2)
now,
b = -1
m = 2/3
x = x ----(x remains same)
Therefore,
y=> mx + b
by substituting the values, we get,
y=> (2/3)x - 1

12k+6=4k–8 what is the value of K?
Answer:
k = 28/7 which equals 4
Step-by-step explanation:
1/2k + 6 = 4k - 8
1/2k - 4k = -8 - 6
1/2k - 8/2k = -14
-7/2k = -14
k = -14 * - 2/7
k = 28/7 which equals 4
Answer:
k=-7/4 or -1.75

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below. StartFraction 28 feet minus 7 over 14 feet minus 7 EndFraction = StartFraction 21 over 7 EndFraction Which is Zelie's error? Zelie should have divided both numbers by 14. Zelie should have written the ratio as StartFraction 28 feet over 7 feet EndFraction. Zelie should have written the ratio as StartFraction 14 feet over 28 feet EndFraction.
Answer:
Zelie should have divided both numbers by 14
Step-by-step explanation:
Given
[tex]Actual = 28[/tex]
[tex]Measured = 14[/tex]
Required
Spot and correct Zelie's mistake
[tex]Zelie = \frac{28 - 7}{14 - 7} = \frac{21}{7}[/tex]
Scale is calculated as:
[tex]Actual = Measured * Scale[/tex]
[tex]28 = 14 * Scale[/tex]
Divide 28 and 14 by 14
[tex]28/14 = 14/14 * Scale[/tex]
[tex]2 = 1 * Scale[/tex]
[tex]2 =Scale[/tex]
[tex]Scale = 2[/tex]
Notice at this point:
[tex]28/14 = 14/14 * Scale[/tex]
Both sides were divided by 14.
Hence, option A answers the question.
Answer:
A. Zelie should have divided both numbers by 14.

I took the quiz and got it right.

Gina has been offered a job as a dog walker. The job pays $10 each week plus $5 per dog walked. Gina’s goal is to earn $75 each week. What is the number of dogs Gina must walk in order to reach her weekly goal?
Answer:
The answer is 5 dogs.
Step-by-step explanation:
If she earns $15 each week, you have to divide that with 75. 75/15=5. Thus, each week she needs to walk 5 dogs to reach her goal.
Answer:
13 DogsStep-by-step explanation:
65 Divided by 5
Equals 13
Therefore,
If you get 10 dollars each week then subtract 75 by 10 and you get,
65, Then divide that by 5 to get your answer

The equation below can be used to determine I, the am
simple interest on a loan.
I= prt, where p is the principal, r is the rate of the loan,
the length of the loan in years.
Which of these is the equation solved in terms of r?
Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
[tex]I=Prt[/tex] ...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,
[tex]\dfrac{I}{rt}=\dfrac{Prt}{rt}\\\\P=\dfrac{I}{rt}[/tex]
So, P can be solved as : [tex]P=\dfrac{I}{rt}[/tex].

HELP WITH MY MATH EXAM i don't know what to do and my head hurts a lot
Answer:
x = 154/13
Step-by-step explanation:
You are given the measures of all three angles in a triangle
so according to the Triangle Sum Theorem:
∠MNO + ∠OMN + ∠NOP = 180
1. Substitute the measures of the angles into the equation:
(3x + 11) + (2x + 20) + (8x - 5) = 180
2. Combine like terms:
(3x + 2x + 8x) + (11 + 20 -5) = 180
13x + 26 = 180
3. Isolate x by subtratcing 26 from both sides
13x + 26 -26 = 180 -26
13x = 154
4. Solve for x by dividing both sides by 13
13x/13 = 154/13
x = 154/13

Name all the angles that have V as a Vertex
Answer:
Step-by-step explanation:
An angle is formed by joining two rays or two lines meeting at a point.
Common endpoint is called the vertex of the angle.
From the picture attached,
Three rays VJ, VI and VH are meeting at a common point V.
Therefore, angles formed at the common vertex V are,
Angle between ray VJ and VI,
(∠5 or ∠JVI)
Angle between ray VH and VI
(∠6 or ∠HVI)
Angle between ray VJ and VH
∠JVH.

A shop owner offered a 20% discount off the regular price of a mirror. The amount of the discount is $5. What is the regular price of the mirror?
Answer:
25 dollars
Step-by-step explanation:
If 20 percent of the initial price was 5, you can create the equation:
0.2x=5, with x being the regular price.
Multiply both sides by 5:
x=25
Answer:
25$
Step-by-step explanation:
20/100 can be rounded down to 1/5 meaning all you have to do is multiply 5 by 5
5 times 5 is 25
25$ was the original price

There are 2 overlapping triangles here. If the vertical lines are parallel, then these triangles are similar, and corresponding sides occur in a fixed ratio. In particular, we have
2/3 = (2 + x) / (3 + (x + 7))
Solve for x :
2/3 = (2 + x) / (10 + x)
2 (10 + x) = 3 (2 + x)
20 + 2x = 6 + 3x
14 = x
