Answer:
slope: 7
y-intercept: 1/2
Step-by-step explanation:
Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).
[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]
So you know that m = 7, so the slope is 7
and
b = 1/2, so the y-intercept is 1/2.
What is the perimeter of the triangle?
Answer:
The answer is 36
Step-by-step explanation:
First, suppose that each square is the unit length, and from it the length of the hall can be calculated and we find that it is equal to 10, then to find the value of the other two we drop a column of the vertex of the triangle on the base and find that its length is 12 units and it divides the base into two equal halves, so we determine that each side equals 13 units using Pythagoras and it will be The lengths of the sides of the triangle are 10, 13, 13
Then the perimeter is
[tex]10 + 13 + 13 = 36[/tex]
3 teas and 2 coffees have a total cost of £7.80.
5 teas and 4 coffees have a total cost of £14.20.
Work out the cost of one tea and the cost of one coffee.
Answer:
coffee is £1.80 per cup and tea is £1.40 per cup
Step by Step:
The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup
At the gym, Hillary swims every 6 days, runs every 4 days and cycles every 16 days. If she did all three activities today, What will be the closest day that you will do the three exercises the same day?
GCF AND LCM
Step-by-step explanation:
We need to do LCM in this case.
2_|_ 6,4,16
2 _|_ 3,2,8
_|_ 3, 1,4
It is not divisible further.
So, LCM is 2×2×3×4 = 48
So, 48 is the answer.
Hope it helps :)

On a map, 1 inch equals 5 miles. Two cities are 3 inches apart on the map. What is the actual distance between the cities?
The actual distance between the cities is ___ miles.
Answer:
15
Step-by-step explanation:
cross multiplying, [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{x}[/tex]
then it would be 15 =1x
and 1x is basically just one, so 15 = x

Gavin took a taxi home from the airport. The taxi fare was $7 plus an additional $0.65 per mile.
Gavin gives the driver a $3 tip when he arrives home. If Gavin paid a total of $62.65 with the tip,
what is the distance between the airport and Gavin's house?
Answer:
81
Step-by-step explanation:
$62.65-$7-$3=$52.65
Distance->52.65÷0.65=81

Find two integers whose sum is -9 and product is -10
Step-by-step explanation:
if the two integers are x and y
xy=-10
x+y=-9
x+(-10/x)=-9
x2+9x-10=0
(x-1)(x+10)=0
x=1 or x=-10
if x=1, y=-10
if x=-10, y=1
so the two integers are 1 and -10

Answer: Median 38 / Mean 24.5
Step-by-step explanation:
The median is 38
and
The mean is 24.5
To find the median just find the number in the middle of an odd set
but if it happens to be an even number add the 2 middle numbers together and divide them by 2
To find the Mean add all of the numbers and divide them by the number of sets ( in this instance its 4 )
Consider the quadratic expression given below.
4x^2 + 8x - 60
Factor the following expression completely.
Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form

A horizontal line includes the points (0, -2) and (3, -2). Find the slope of the line.
wil give BRAINLIEST
pls answer correctly
Answer:
We conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]Step-by-step explanation:
Given that the line includes the points
(0, -2)(3, -2)We need to find the slope of the line containing the points between (0, -2) and (3, -2) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, -2)(x₂, y₂) = (3, -2)now substituting (x₁, y₁) = (0, -2) and (x₂, y₂) = (3, -2) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-2-\left(-2\right)}{3-0}[/tex]
[tex]m=\frac{-2+2}{3}[/tex]
[tex]m=\frac{0}{3}[/tex]
[tex]m = 0[/tex]
Therefore, we conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]prove that there is only one circle determined by three noncollinear points
Answer:
O lies on the perpendicular bisector of AB. ... Then, O' will lie on the perpendicular bisector PQ and RS. We know that, two lines cannot intersect at more than one point, So O' must coincide with O. Hence, there is one and only one circle passing through three non collinear points
