Answer:
25.
Step-by-step explanation:
We can write the expression as 10x + 2.5x where x is the tens digit.
So reversed we have 25x + x.
- and 25x + x - (10x + 2.5x) = 27
22.5x - 9x = 27
13.5x = 27
x = 2 and 2.5x = 5.
So the number is 25.
1 meter is 100 centimeter, as "centi" means 1 hundredth:
So 100 centimeter means 100-"1 hundredth" meters, which is 1 meter.
In short, since 1 meter is 100 centimeters, 8 meters are 800 centimeters.
Answer: 800 cm

EXPLANATION
To find the distance between home and work, we have to use the formula:
![D\text{ = }\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
We have that home is at point (3, -3) and work is at point (0, 6).
Therefore:
(x1, y1) = (3, -3)
(x2, y2) = (0, 6)
Therefore, we have that:
![\begin{gathered} D\text{ = }\sqrt[]{(0-3)^2+(6-(-3))^2} \\ D\text{ = }\sqrt[]{(-3)^2+(6+3)^2}\text{ = }\sqrt[]{(-3)^2+(9)^2} \\ D\text{ = }\sqrt[]{9\text{ + 81}}\text{ = }\sqrt[]{90} \\ D\text{ = 9.5} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B%280-3%29%5E2%2B%286-%28-3%29%29%5E2%7D%20%5C%5C%20D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B%28-3%29%5E2%2B%286%2B3%29%5E2%7D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B%28-3%29%5E2%2B%289%29%5E2%7D%20%5C%5C%20D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B9%5Ctext%7B%20%2B%2081%7D%7D%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7B90%7D%20%5C%5C%20D%5Ctext%7B%20%3D%209.5%7D%20%5Cend%7Bgathered%7D)
The answer is 9.5
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)
