Answer:
Step-by-step explanation:
use substitution and solve this 8x+4(-2x+3)=12
with the 4 distributed its
8x-8x+12=12
then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0
Answer:
1. 14
2. 20
3. 12
4. -400
5. 6
6. 21
7. 11
8. 16
9. 40
10. 49
11. 12
12. IDK
Step-by-step explanation:
1. 16-2=14
2. 16+4=20
3. 6 X 2 = 12
4. -400/-10 (negative divided by a negative equals a positive) = 40
5. 6 X 6 = 36
6. 16+5=21
7. 23-12=11
8. 4 X 16 = 64
9. 36-16=20, 20 X 2 = 40
10. 400-8=392, 392/8= 49
11. 912-612=300, 300/25 = 12
12. Sorry too confusing.
<span>y-intercept when x = 0
so if x = 0, y = -3
answer
</span><span>y-intercept (0, -3)</span>
First thing to do is solve the given equation for v
-11v-7 = 4
-11v = 4+7
-11v = 11
v = 11/(-11)
v = -1
Once we know this, we can use it to compute the following
7v-10 = 7*(-1) - 10 = -7 - 10 = -17
--------------------------------
Answer: -17
You can observe that angle 1 and angle with 47° are inside a parallelogram.
Consider that the sum of the internal angles of a parallelogram is 360°.
Moreover, consider that the angle at the top right of the parallogram is congruent with the angle of 47°, then, such an angle is if 47°.
Consider that angle down right side is congruent with angle 1, then, they have the same measure.
You can write the previous situation in the following equation:
47 + 47 + ∠1 + ∠1 = 360 simplify like terms
94 + 2∠1 = 360 subtract both sides by 94
2∠1 = 360 - 94
2∠1 = 266 divide by 2 both sides
∠1 = 266/2
∠1 = 133
Hence, the measure of angle 1 is m∠1 = 133°
