Answer:
The correct option is A
A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10
Step-by-step explanation:
We have been given a system of equation:
y = -13x + 17
y = 5x - 23
We have to determine the best window range from the following options:
A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10
B) -20 ≤ x ≤ 0 , -20 ≤ y ≤ 0
C) 0 ≤ x ≤ 20, 0 ≤ y ≤ 20
D) 20 ≤ x ≤ 40 , 20 ≤ y ≤ 40
The graph of both the equation is attached below, we can see that the graph shows the solution at the point (2.222, -11.869), where x is positive and y is negative
Now consider the options
Option A includes the solution
Option B doesn't show positive values for x
Option C doesn't show negative values for y
Option D doesn't include the x or y part of the solution
I recommend using desmos if you wanna know what a graph looks like !
Answer:
Step-by-step explanation:
1). m∠AEC = m∠AEB + m∠BEC
= 21° + 37°
= 58°
2). m∠BED = m∠BEC + m∠CED
= 37° + 44°
= 81°
3). m∠IKF = m∠IKH + m∠HKG + m∠GKF
= m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]
= 2∠IKH + m∠HKG
103° = 2∠IKH + 41°
2(∠IKH) = 103 - 41
m(∠IKH) = 31°
4). m∠AED = m∠AEB + m∠BEC + m∠CED
= 21° + 37° + 44°
= 102°
5). m∠JKG = 108°
m∠JKG = m∠JKI + m∠IKH + m∠HKG
108° = m∠JKI + 31° + 41°
m∠JKI = 108° - 72°
m∠JKI = 36°
6). m∠HKF = m∠GKF + m∠HKG
= m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]
= 31° + 41°
= 72°
7). m∠NQO = m∠MQN = 64°
8). m∠JKF = m∠JKI + m∠IKF
= 36° + 103°
= 139°
8). m∠MQO = 2(m∠NQO)
= 2(64)°
= 128°
9). m∠LQO = 156°
m∠LQM = m∠LQO - m∠MQO
= 156° - 128°
= 28°
10. m∠NQP = m∠NQO + m∠OQP
= 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]
= 64° + 28°
= 92°
Answer:
1. 4/12 , 6/8
2. 16/12 , 3/4*
3. 3/2 , 15/14
4. 10/16 , 5/8
10/16 = 5/8
Which ratio forms a proportion with 9/15?
1. 6/10
2. 16/21
3. 36/50
4. 45/70
9/15 = 3/5 which is 6/10
A textbook weighs 2.5 pounds. How many kilograms does the textbook weighs? Round your answer to the nearest tenth of a pound. 1 kg = 2.2 lb
1. 1.1 kg
2. 1.8 kg
3. 5.5 kg
4. 4.7 kg
2.5 lbs * (1 kg/2.2 lbs) =
Solve the proportion using number sense. 2/8 = x/ 48
1. 6
2. 12
3. 16
4. 8
8 * 6 = 48
so what is 2 times 6 ?
or another way
1/4 * 48 = 12
Solve the proportion using cross products. 18/20 = k/110
1. 99
2. 122
3. 3.3
4. 2.9
20 k = 18*110
2 k = 18 *11
k = 9 * 11
Are the ratios 8/12 and 10/25 proportional? Explain
8/12 = 2/3
10/15 = 2/3 so no way 10/25 is 2/3
A 10-acre field produced 750 bushels of corn. At the rate, how much corn can be produced from a 14-acre field?
14 acres * ( 75 bushels/acre)
or
10/750 = 14/x
