(6, y) and (-8, 4); slope: 1/7
For the given points (6, y) and (-8, 4) having slope = 1/7 the value of y = 10.
What is the slope of a line?
A line's slope, also known as its gradient, is defined as the value of a line's steepness or direction in a coordinate plane. Slope can be calculated using various methods given a line equation or the coordinates of points on a straight line.
If P(a, b) and Q(c, d) are two given points on a coordinate plane, then the slope of line PQ can be computed using the formula
[tex]Slope(m)=\frac{d - b}{ c - a}[/tex]
The given points are (6, y) and (-8, 4).
and the slope of the line is given as m = 7.
By using the slope of a line formula, we get
[tex]m = \frac{8-y}{-8-7}\\\\ \frac{1}{7}= \frac{8-y}{-8-7}\\\\\frac{1}{7}= \frac{8-y}{-14}\\\\\\8-y=-2\\y=8+2\\y=10[/tex]
Hence, the value of y is 10.

i need the answers for the problems
Answer:
I believe the first one is log8(5/3), the second is log5(3), and the third is -2log2(5)
Step-by-step explanation:
I got this by applying the properties of logarithms which are:
logₐ mn = logₐ m + logₐ n (product property)
logₐ m/n = logₐ m - logₐ n (quotient property)
logₐ mn = n logₐ m (power property)
logb = (log꜀ a) / (log꜀ b) (change of base property)

x-3=0
so x = 3
-(y-2)=0
so y = 2
vertex = (3,2)
Consider the equation and the following ordered pairs: (6,y) and (x,1).
y=−2x+5
The values of x and y are 2 and -7 respectively, this forms an ordered pair of (6,-7) and (2,1).
What are the the values of x and y to complete the given ordered pair?Given the equation and ordered pair the question;
y = -2x + 5Point: (6,y) Point; (x,1)To determine, the y-value, plug the x-value into the equation and solve for y.
y = -2x + 5
Plug in x = 6
y = -2( 6 ) + 5
y = -12 + 5
y = -7
Determine the x-value by plunging in the y-value into the equation and solve for x.
y = -2x + 5
Plug in y = 1
1 = -2x + 5
1 + 2x = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2.
Therefore, the ordered pair are (6,-7) and (2,1).

According to the graph provided, the weight for someone who is 1.4 meters tall is predicted to be close to kilograms
According to the scatterplot (graph) provided, the weight for someone who is 1.4 meters tall is predicted to be 34.8 kilograms.
What is a scatterplot?A scatterplot is also referred to as scatter diagram, scattergram, or scatter chart and it can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association between the data set.
For this exercise, the height (M) was plotted on the x-axis of the scatterplot (graph) while the weight (in kg) would be plotted on the y-axis of the scatterplot (graph).
From the scatterplot which models the relationship between the height (M) and weight (in kg) of a person, an equation for the line of best fit is given by:
Weight, kg = -114.3 + 106.5M
When M = 1.4 meters, we have the following weight:
Weight, kg = -114.3 + 106.5(1.4)
Weight, kg = -114.3 + 149.1
Weight, kg = 34.8 kg.

The value of x so the the the function has the given value is as follows:
m(x) = 2; x = - 10w(x) = - 18; x = - 18How to find the value of the input of a function?A function relates an input to an output.
In other words, a function is a special relationship among the inputs and their outputs codomain) where each input has exactly one output value.
Therefore, let's find the value of x so that the function has the given values.
m(x) = -3/5x - 4; m(x) = 2
let's find the value of x when m(x) = 2
2 = - 3/5x - 4
2 + 4 = - 3/5x
6 = - 3/5 x
cross multiply
-3x = 30
x = 30 / - 3
Hence,
x = - 10
w(x) = 5/6x - 3; w(x) = -18
let's find the value of x when w(x) = -18
- 18 = 5/6x - 3
- 18 + 3 = 5 / 6 x
- 15 = 5 / 6 x
5x = - 90
x = -90 / 5

What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Assuming the prices for cat and dog food have not changed over the past two weeks, find and solve the system of equations which can be used to determine the cost of a bag of cat food, c, and the cost of a bag of dog food, d.
c=cost of a bag of cat food

One bag of cat food costs $6 and one bag of dog food costs $9.
What is system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
The problem states that c equals the cost of bag of cat food and d equals the cost of bag of dog food.
Last week she paid $117 for 6 bags of cat food and 9 bags of dog food.
Therefore, the equation becomes,
6c + 9d = 117 ..(1)
This week she paid $87 for 4 bags of cat food and 7 bags of dog food.
Therefore, the equation becomes,
4c + 7d = 87 ..(2)
Now to solve the system of equations
To solve the first equation for c.
6c + 9d = 117
6c = 117 - 9d
[tex]c = \frac{117}{6}-\frac{9d}{6}[/tex]
Plug value of c in equation (2).
[tex]4(\frac{117}{6}-\frac{9d}{6}) +7d = 87\\78 - 6d + 7d = 87\\d = 87-78\\d = 9[/tex]
Plug d = 9 in equation (1)
6c + 9(d) = 117
6c + 9(9) = 117
6c + 81 = 117
6c = 117 - 81
6c = 36
c = 6
Hence, one bag of cat food costs $6 and one bag of dog food costs $9.
