Answer:
When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.
8=4(-1)+b
8=-4+b
b=12
So, the equation of the line is y=4x+12.

The graph shows the number of sprays an automatic air freshener dispenses, y, in x minutes:
A graph is shown. On the x-axis, the values are from 0 till 150 in increments of 30 for each grid line, and on the y axis, the values are from 0 to 30 in increments of 6 for each grid line. The title of the graph on the x-axis is Time in minutes, and the title on the y-axis is Number of Sprays. A line is shown connecting points on ordered pair 30, 6 and 60, 12 and 90, 18 and 120, 24. The title for the graph is Dispense Rate.

Answer:
Point-slope equation: y - 10 = 2(x - 3)
Step-by-step explanation:
Given the slope of the line, m = 2, and the point, (3, 10):
Let the slope (m) = 2
(x₁, y₁) = (3, 10)
Substitute these values into the point-slope form, y - y₁ = m(x - x₁):
y - y₁ = m(x - x₁)
y - 10 = 2(x - 3) ⇒ This is the point-slope form.
Using the information in the map, what is the distance between Camden and Lowell? Explain your reasoning using correct Geometry justification. For the ease of symbols used in your justification, let Morsetown be point o, Meridian be point M, Grenata be point G, Camden be
point C, and Lowell be point L.
The map below shows five different towns. The town of Meridian wasgiven its name because it lies exactly halfway between two pairs of cities:
Camden and Grenata, and Lowell and Morsetown.
Answer:
5 miles
Step-by-step explanation:
We are looking at triangles LCM and OGM.
Point M is the midpoint of segments LO and CG.
That makes segments CM and GM congruent (side).
Then angles CML and GMO are congruent since they are vertical angles (angle).
Finally, segments LM and OM are also congruent because of the midpoint (side).
By SAS, triangles LCM and OGM are congruent.
Then by CPCTC, segments LC and OG are congruent.
Since OG = 5 miles, then LC = 5 miles.
Answer: 5 miles
A number when multiplied by 4 exceeds itself by 45 . find the number
So we know that the number x is multiplied by 4, and then is bigger then itself by 45, so so lets set up this equation.
4x = x + 45
The 4x is our x multiplied by 4 and the x + 45 is when it exceeds itself by 45.
Now lets solve:
4x = x + 45
Bring x to one side to isolate the variable:
4x - x = 45
3x = 45
Now we divide the 3 from the 3x in order to fully isolate the variable:
x = 45 / 3
x = 15
Lets plug 15 in to double check the answer:
4(15) = 15 + 45
60 = 60
Yes!
This means that 15 is the number multiplied by 4 and exceeded by 45.

find the midpoint of the segment with the endpoints (-2,-6) and (8,8)
Answer:
(3,7)
Step-by-step explanation:
no time thank you
Answer:
The midpoint of the segment with points (-2,-6) and (8,8) is (3,1).
What is the midpoint?
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The given points are ( -2,-6) and (8,8). The formula to calculate the midpoint is given below:-
Midpoint = ( x₁ + x ₂ ) / 2 , ( y₁ + y₂ ) / 2.
Midpoint = ( -2 + 8 ) / 2 , ( -6 + 8 ) / 2
Midpoint = (3,1)
Therefore, the midpoint of the segment with points (-2,-6) and (8,8) is (3,1).

what is 2(1+5x)-3x=72 solve for x please
Answer:
x = 10
Step-by-step explanation:
2(1+5x)-3x=72
Distribute
2 + 10x -3x = 72
Combine like terms
2+7x=72
Subtract 2 from each side
2+7x-2 = 72-2
7x = 70
Divide by 7
7x/7 = 70/7
x = 10

It costs $68 for 16 sq. feet of flooring. How much does it cost for 12 sq. feet of flooring? (how to write the expression too pls!)
Answer:
It costs $51
Expression:
16x = 68
12x = ?
Step-by-step explanation:
Lets first find out how much one sq. ft. of flooring costs:
16x = $68
x = $68/16 = $4.25
Next, lets multiply the unit rate by 12 to find the answer:
12x = Answer
12 * (4.25) = $51
Answer:
51
Step-by-step explanation:
68÷16 = 4.25
12 × 4.25 = 51
Solve the system of equations by substitution.
y = 4x -1
2x + 2y = 3
Step-by-step explanation:
y = 4x - 1
2x + 2y = 3
2x + 2(4x - 1) = 3
2x + 8x - 2 = 3
10x = 3 + 2
x = 5/10
x = 1/2
y = 4x - 1
y = 4(1/2) - 1
y = 2 - 1
y = 1
(x,y) = (1/2 , 1)

Answer:
3. m1=82, m4=59. m5=98, m6=51, m7=79, m9=51, m10=129
4. m1=36, m2=90, m4=36, m5=90, m6=54, m7=126, m8=54, m9=126, m10=54, m11=36, m12=144, m13=36, m14=144
Step-by-step explanation:
3. m2=98, m3=23, m8=70
by supplementary angles, m1 + m2 = 180, since we know m2, we have m1 = 180 - 98 = 82. by corresponding angles we have m1 = m3 + m4, since we know m1 and m3, we have m4 = 82 - 23 = 59. again by supplementary angles, m3 + m4 + m5 = 180. we know m3 and m4 so m5 = 180 - 23 - 59 = 98. by alternate interior angles m4 = m7, so m7 = 59. by supplementary angles m6 + m7 + m8 = 180 so m6 = 180 - 70 - 59 = 51. by corresponding angles m6 = m9 so m9 = 51. by supplementary angles m9 + m10 = 180 so m10 = 129
4. m3=54
m2 is a right angle so m2=90. by complementary angles m3 + m4 = 90 so m4 = 36. by vertical angles m1=m4 so m1=36. by vertical angles m2=m5 and m3=m6 so m5=90 and m6=54. by corresponding angles m7 = m2+m1 so m7=126. by supplementary angles m7+m8 = m7+m10 = 180 so m8=10=54. by vertical angles m7=m9 so m9=126. by corresponding angles m1=m11 and m3=13 so m11 and m13 = 54. by supplementary angles m12+m13= m11+m14 = 180, so m12 = m14 = 144

Bill's car gets 30 miles to the gallon. For every gallon of gas it consumes, his car runs 30 miles. Use this information to determine whether this
relation is a function.
Part b using the equation you found in part a substitute three different values for x. How many values of y do you get for each value of x? Type the values in the table
Answer:
Part a: Bill’s car travels 30 miles per gallon of gas. If y represents the number of miles the car travels on x gallons of gas, the equation that represents this situation is y = 30x.
Part b: gallons of gas (x) miles (y)
1 30
2 60
3 90
Part c: There is no x-value that would lead to multiple y-values.
Part d: Yes, y = 30x is a function, because for every input, or x-value, there is only one output, or y-value.
