Answer:
![-\frac{2}{5}.](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7D.)
Step-by-step explanation:
1) if to re-write the given equation into slope-interception form, then:
![y=\frac{5}{2}x-7;](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B2%7Dx-7%3B)
the slope of the given line is 5/2;
2) according to the rule of perpendicular, the required slope should be:
s*(5/2)=-1;
3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.
Answer:
60%
Step-by-step explanation:
A 40% discount means that 40% will be off, meaning you won't have to pay 40% of the original price. Therefore, you only pay 60% of the original price (100% - 40% = 60%).
Answer:
Y = 2/3x-8/3
Step-by-step explanation:
y − 4 = 2/3 ( x − 3)
y − 4 = 2/3x -2
y = 2/3x +2
~~~~~~~~~~~~~~~~~
-2 = 2/3(1) + b
b = -2 2/3 = -8/3
Answer:
80
Step-by-step explanation:
We have, 75% × x = 60
or,
75/ 100 × x = 60
Multiplying both sides by 100 and dividing both sides by 75,
we have x = 60 × 100/75
x = 80
Answer:
A
All real numbers
Step-by-step explanation:
Given in the question a graph
To find the range of graph
The range is the set of possible output values, which are shown on the y-axis.
We can see in the graph that for negative values of x it have positive values, zero and negative values of y.
The graph extends vertically from (-∞,∞), along the y axis. So the range of the function shown in the graph is (-∞,∞).
Hence, it is concluded that range is All real numbers
