Answer:
He is correct
Step-by-step explanation:
Put the first equation into y = mx + b by isolating y:
4x + 2y = 10
2y = -4x + 10
Divide each side by 2:
y = -2x + 5
So, putting the first equation into y = mx + b got us the same equation as the second one, y = -2x + 5.
Since they are the same, the equations are equivalent.

im sorry if this is wrong but im 99% sure this is right
i only put things in parenthesis to make things work better in my brain
Answer:
m = -2
Step-by-step explanation:
4 + 4{m + 1} = 0 {Subtract 4 form both sides}
4{m + 1} = -4
4m + 4 = -4 {Subtract 4 form both sides}
4m = -4 - 4
4m = -8 {Divide both sides by 4}
m = -8/4
m = -2

Step-by-step explanation:
= 40 + [ 3 { 18 ÷ ( 9 - 3 ) - 11 - 9 } + 4 ]
= 40 + [ 3 { 18 ÷ 6 - 11 - 9 } + 4
= 40 + [ 3 { 3 - 20 } + 4
= 40 + [ 3 {- 17 } + 4
= 40 + ( - 51 ) + 4
= 40 + 4 - 51

19 - 2k = 3k - 1
+3k +3k
19 + 1k = -1
-19 -19
k = -20
Answer:
You aren't supposed to add 3k
Step-by-step explanation:
3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide
19-2k= 3k-1
-3k -3k
19-5k= -1
-19 -19
-5k= -20
-5/-5= -20/-5

A cab service charges $4 plus $1.50 per mile. Kate wants to spend no more
than $28 on cab fare. In this inequality, m represents the greatest number of
miles Kate can travel in the cab.
28 > 4+1.5m
Solve the inequality. What is the value of m?
O A. 8
O B. 16
O C. 28
O D. 30
Answer:
b
Step-by-step explanation:
took the test i got bj : fz wf
The value of m in the inequality 28 > 4+1.5m is 16
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
To solve for m, we need to isolate it on one side of the inequality.
We can start by subtracting 4 from both sides:
28 - 4 > 1.5m
Simplifying:
24 > 1.5m
Next, we can divide both sides by 1.5:
16 > m
So Kate can travel at most 16 miles in the cab if she wants to spend no more than $28 on cab fare.
Therefore, the value of m in the inequality 28 > 4+1.5m is 16

How many perfect cube divisors does 160,000 have?
Answer:
160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
Step-by-step explanation:
To determine how many perfect cube divisors 160,000 has;
We first need to highlight the factors of 160,000 as follows;
(2 × 2 × 2) × (2 × 2 × 2) × 2 × 2 × (5 × 5 × 5) × 5
As such, the product of numbers in each bracket yield a perfect cube; the expression above then becomes;
2 × 2 × 5 × 8 × 8 × 125.
Therefore, 160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125

Slope is rise/run
Step-by-step explanation: For the original slope get
Find coordinates where the graphed line crosses the grid lines at the intersections. Here, (0,-2) and (2,1) Count the number of squares vertically. That is the rise. It is the difference in y-values. It is the numerator of the fraction. Then count the squares horizontally to get the run. That is the denominator of the fraction.
It is possible to use the expression [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] to calculate the slope.

find x exterior angles
Answer:
The value of x is 27
Step-by-step explanation:
The sum of the exterior angles of the n-side polygon is 360°
Let us use this rule to solve the question
∵ The given polygon has 4 sides
∴ It has 4 exterior angles, one on each vertex
→ By using the rule above
∴ The sum of the 4 angles is 360°
∵ The exterior angles are (2x + 40)°, (4x)°, (x + 50)°, and (3x)°
→ Add them, then equate the sum by 360
∴ (2x + 40) + (4x) + (x + 50) + 3x = 360
→ Add the like terms in the left side
∵ (2x + 4x + x + 3x) + (40 + 50) = 360
∴ 10x + 90 = 360
→ Subtract 90 from both sides
∵ 10x + 90 - 90 = 360 - 90
∴ 10x = 270
→ Divide both sides by 10
∴ x = 27
∴ The value of x is 27

Johan needs to send out thank you cards after his graduation party he would buy a package of thank you cards for $8.50, or he could buy x individual thankyou cards for $0.15 each what is the largest value of x that would make buying the individual card less expensive than buying the package
A. 54
B. 55
C. 56
D. 57
The largest value of x that would make buying the individual card less expensive than buying the package is 57.
What is the largest value of x?The total cost of buying the individual thankyou cards is the product of the cost of buying one card and the number of cards bought.
Total cost of buying the individual thankyou cards = cost per card x number of cards bought
$0.15 × x = $01.5x
The inequality equation that would be used to represent this question is
(total cost of individual thankyou cards) > cost of the package
$0.15x > $8.50
In order to determine the value of x, divide both sides of the equation by 0.15
x > (8.50 / 0.15)
x > 56.67
x > 57 to the nearest whole number

Dr. Brown, a veterinarian, noticed that he only had about 200 grams of cat treats left. So, he bought a new 2.5-kilogram jar. If he uses about 100 grams of cat treats every week, in how many weeks will he run out?
(Sorry if I'm asking so many questions I really need help!)
The number of weeks that they cat treats will train out is 27 weeks.
How to calculate the value?From the information given, the total grams will be:
= 200 + (2.5 × 1000)
= 200 + 2500
= 2700 grams.
Then he uses about 100 grams of cat treats every week, the number of weeks will be:
= 2700 / 100
= 27
There'll be 27 weeks.

Look at the picture for the question.
Answer:
Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.
Step-by-step explanation:
We are told that his monthly profit is given by the relation;
P = 32.5x - 845
Where x is number of pictures he needs.
We want to find what the x - intercept represents.
x intercept means that the y-value at that point is zero.
Thus, x-intercept means the profit is 0.
If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.
Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.

They are called rational because they are the ratio, or quotient, of two integers
numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end and does not repeat a pattern.
