Step-by-step explanation:
solve:
3x + 2y = -4
x - 2y = 4
Topic : Linear equations in two variables.
Given :
3x + 2y = -4 ––– (i)x - 2y = 4 ––– (ii)Solution :
Now,
(i) + (ii)
[tex] \qquad \sf \: { \dashrightarrow 3x + 2y + (x - 2y) = - 4 + 4}[/tex]
[tex] \qquad \sf \: { \dashrightarrow 3x + 2y + x - 2y = 0}[/tex]
[tex] \qquad \sf \: { \dashrightarrow 3x \: \cancel{ + 2y} + x \: \cancel{- 2y} = - 4 + 4}[/tex]
[tex] \qquad \sf \: { \dashrightarrow 4x = 0}[/tex]
[tex] \qquad \bf \: { \dashrightarrow x = 0}[/tex]
Now, substituting the value of x in Eq (i) :
[tex]\qquad \sf \: { \dashrightarrow 3x + 2y = -4}[/tex]
[tex]\qquad \sf \: { \dashrightarrow 3(0) + 2y = -4}[/tex]
[tex]\qquad \sf \: { \dashrightarrow 0 + 2y = -4}[/tex]
[tex]\qquad \sf \: { \dashrightarrow 2y = -4}[/tex]
[tex]\qquad \sf \: { \dashrightarrow y = \dfrac{ - 4}{2} }[/tex]
[tex]\qquad \bf \: { \dashrightarrow y = -2}[/tex]
Therefore, The value of x = 0 and y = -2
The solution to the two given simultaneous equations are; x = 0 and y = -2
How to find the solution to simultaneous equations?We are given the simultaneous equations;
3x + 2y = -4 -----(eq 1)
x - 2y = 4 ------(eq 2)
Add eq1 and eq2 to get;
4x = 0
x = 0/4
x = 0
Substitute 0 for x in eq 2 to get;
0 - 2y = 4
-2y = 4
y = -4/2
y = -2

Solve the system of equations by the substitution method.
5x+4y=38 x=5y−4
Answer:
Step-by-step explanation:
Because x=5y-4 you can substitute 5y-4 into the x in the other equation. This makes 5(5y-4) + 4y = 38. When simplified it gives 25y -20 +4y = 38. Move like terms to each side to get 29y = 58 and get y=2. Then you can substitute 2 into the y in either equation to find x. I will do x=5(2)-4 to get x=6. So x=6 and y=2

Use the number line to help you decide which statement is true.
Answer:
7/8 > 3/4
Step-by-step explanation:
Make the denominators of both fractions the same by mulitplying the numerator (top number) and denominator (bottom number) of the fraction 3/4 by 2:
(3 x 2) / (4 x 2) = 6/8
Now compare 6/8 with 7/8 (the number line is divided into 8 equal parts. Shade 6 and then shade 7. which is bigger?)
7/8 > 6/8
Therefore, 7/8 > 3/4
Answer:
7/8 > 3/4

can somebody help me with this please
Answer:
j = 120 degrees h = 142 degrees
Step-by-step explanation:
First we should solve for j since we can take the hexagon and solve for j using the equation (n - 2) times 180 divided by n. N represents the number of sides the figure has, in this case its a hexagon so there are 6 sides.
(6 - 2) times 180 = 720/6 j equals 120 degrees
Next we can begin to solve for h by noting that h and 38 degrees are supplementary angles. Therefore, h plus 38 degrees equals 180 degrees.
180 - 38 = h h equals 142 degrees

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?
Mel: (2, 50) and (5, 35)
Victor: (1, 60) and (4, 50)
Mel’s rate of change is _. That means that her height in the air decreases _ feet every second.
Victor’s rate of change is _. That means that his height in the air decreases _ feet every second.
Answer:
Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.
Since after 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air, while after 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air, to determine who was descending at a faster average rate and what is Mel's rate of change, the following calculations must be performed:
You must subtract the difference between the two times for each person, and check which is the highest rate between the two.
Mel =
(50 - 35) / (5 - 2) = X
15/3 = X
5 = X
Victor =
(60 - 50) / (4 - 1) = X
10/3 = X
3.33 = X
Therefore, Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.

Which is bigger
3/6 or 2/3
Answer:
2/3
Step-by-step explanation:
2/3 = 4/6
Is 4/6 bigger than 3/6?
Yes.
2/3 is bigger than 3/6.
And also, if you convert 2 of the fractinos to decimals, 2/3 will be approximately 0.67 and 3/6 will be 0.5.
Is 0.67 bigger than 0.5?
Yes.
2/3 is greater than 3/6
How to determine the bigger number?The numbers are given as:
3/6 and 2/3
Express both numbers as decimals to two decimal places
0.50 and 0.67
By comparison, we have:
0.67 is greater than 0.50
This means that:
2/3 is greater than 3/6

Kathy keeps track of the number of baskets she makes while practicing her free throw shots. She finds that out of 18 tries, she makes 7 baskets. If Kathy’s trend continues, about how many baskets should she expect to make out of 60 tries? 18 baskets
The number of basket Kathy will make out of 60 tries is 23 basket.
She keeps track of the number of basket she makes while practicing her free throw shots.
She makes 7 baskets out of 18 tries.
Proportional relationship:This is when quantities have the same ratios. Therefore,
18 tries = 7 baskets
60 tries = ?
cross multiply
number of basket = 60 × 7 / 18
number of basket = 420 / 18
number of basket = 23.3333333333
number of basket = 23 basket.
