The second one because for every x value there is one and only one y value. If you plotted the points and graphed it, you would know it is not a function if it doesn't pass the vertical line test. Notice the same x values show up repeatedly in the other ordered pairs with different y values. Only one y value for every x value
Answer:
x=5
y=12
Step-by-step explanation:
the equation is
12x-5+125=180
12x+120=180
12x=60
x=5
According to the question
8y+29=125
8y=96
y=12
I know this is late but I can still help answer this....
So we know that in December all the deserts altogether had 0.89 mm of rainfall. Now the chart that you have seems to represent the rainfall in August, so we would need to use addition.
0.19 + 0.17 + 0.1 + 0.24 = 0.70 mm
The rainfall altogether would be 0.70 mm in August. Now we compare the difference, we would need to subtract 0.89 mm (December) with 0.70 mm (August).
0.89 - 0.70 = 0.19 mm
There the difference between the two would be 0.19 mm.
Hope this helps!
Answer:
See below.
Step-by-step explanation:
1.
(a) < PMR
(b) < QMR
(c) < QMN
(d) < RMN
2. m < C = 4x - 6
= 4(25) - 6
= 100 - 6
= 94 so < C is obtuse.
3. 8x + 2 = 90
8x = 90 - 2
8x = 88
x = 11.
4.
(a). < DBA and < DBC are right angles (90 degrees) because BD is perpendicular to AC.
(b) < DBA and < DBC are adjacent and they share the ray BD.
(c) < DBe and < ABE are complementary.
(d) < DBA and < DBC are supplementary
(e) 90 - 40 = 50 degrees
(f) 180 - 40 = 140 degrees.
(g) As the angles are complementary
3x + 2 + 4x + 4 = 90
7x = 90 - 2 - 4
7x = 84
x = 12.
Answer:
4/10
Step-by-step explanation:
Louise's family traveled 3/10 of the distance to her grandmother's house on Saturday.
Let us represent total distance = 1
The remaining distance left is calculated as:
1 - 3/10
Lowest common denominator = 10
= 10 - 3/10 = 7/10
They traveled 4/7 of the remaining distance on Sunday.
This is calculated as:
= 4/7 × 7/10
= 4/10
What fraction of the total distance to her grandmother's house was traveled on Sunday?
