Answer:
k = 13
Step-by-step explanation:
If (x-1) is a factor, then f(1) = 0
4*1 + k*1 - 7*1 - 10 = 0
4 + k - 7 - 10 = 0
k - 13 = 0
k = 13

A candy store sells lollipops and the money they collect is shown in the graph. X=number of lollipops y=cost select the true statement
Help please I have no idea
Step-by-step explanation:
See the attached picture !
❀ [tex] \underline{ \underline{ \text{Like \: terms}}} : [/tex]
Like terms are those which have the same base. For instance : 3y & 2y are like terms since they have same base i.e y❀ [tex] \underline{ \underline{ \text{Unlike \: terms}}} : [/tex]
Unlike terms are those which have the different base. For instance : 5x & 2p are unlike terms since they have different base ( i.e 5x has the base 'x ' whereas 2p has the base ' p ' )

What is the slope & y-intercept for
y= -2x - 5 ?
Answer:
Slope = 2, and y intercept = -5
Answer:
The overall equation for slope-intercept is
y = mx + b
M would equal slope
B would be equal y-intercept.
So, judging from both equations now,
-2 is slope, while y-intercept is -5
If you are confused on why the y-intercept is -5 I will answer it for you. Have a good day ^-^

If 5 miles = 8 km, about how many miles would be equal to 30 km? Show how you decided.
Complete the ratio that can be used to solve this problem.
miles
? miles
30 km
8 km
Answer:
18.75 milesStep-by-step explanation:
8 km = 5 miles
1 km = ( 5 ÷ 8 ) miles
1 km = 0.625 miles
so therefore,30 km = 30 × 0.625 miles
30 km = 18.75 miles

What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. In discrete mathematics, and more specifically in graph theory.
A graph is a structure consisting of a set of objects, some of which are "related" in some way. The objects correspond to mathematical abstractions known as vertices, and each pair of related vertices is known as an edge.
1. The graph in option 1 is Neither. It is not discrete and continuous.
2. The graph in option 2 is discrete. The values of the data are not in a specific pattern.
3. The graph in option 3 is discrete. The values of the data are not in a specific pattern.
4. The graph in option 4 is continuous. The points in the graph are varying continuously.

does anyone know how to do this by solving with substitution
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3

Solve for x -12=-32+55
Answer:
x = 35
Step-by-step explanation:
I solved for x by simplifying both sides of the equation, then isolating the variable.
Hope this helps:)
Answer:
Step 1: Simplify both sides of the equation.
x−12=−32+55
x+−12=−32+55
x−12=(−32+55)(Combine Like Terms)
x−12=23
x−12=23
Step 2: Add 12 to both sides.
x−12+12=23+12
x=35

If the perimeter of a square is 5 feet now many Inches long is each side of the square
Answer:
The perimeter is 60 inches in total, and 15 for each side.
Step-by-step explanation:
The perimeter of a square is four times the length of one of its sides. So you divide 5 by 4 to get the length of each individual side.
5feet /4 sides = 1.25 feet
So each side is 15 inches long.

How do you divide -15/-5
Answer:
3
Step-by-step explanation:
When you divide two negative numbers, the answer is positive. Since - 15 and -5 are both negative, the answer will have to be positive. Divide 15/5 (just as you would with postive numbers) to get 3 and don't do anything else. The answer has to be 3 because 3 * - 5 = -15 (the opposite of division is multiplication).

Negative four times a number decreased by nine is greater than negative thirteen
Answer:
x<1
Step-by-step explanation:
Le the unknown number be x;
Negative four times a number is expressed as -4x
Negative four times a number decreased by nine is expressed as -4x - 9
If this expression is greater than negative thirteen, then;
-4x - 9 > -13
-4x - 9+9 > -13+9
-4x > -4
x < -4/-4
x < 1
Hence the required solution is x<1
