Answer:
Step-by-step explanation:
The slope intercept form of a line is given as:
y = mx + c
Where m is the slope and c is the y-intercept
Let's rearrange the equation given in this form:
2x - 5y = -11
5y = 2x + 11
y = 2/5 x + 11/5
So the slope is 2/5
Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2
Thus, equation would become: y = -5/2x + c
Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,
Thus, the equation of perpendicular line is:
Answer:
Step-by-step explanation:
0.4 × 3.2
Convert to fraction
0.4 = 4/10 = 2/5 & 3.2 = 32/10 = 16/5
0.4 × 3.2 = 2/5 × 16/5 = 32/25 = 1.28
Without conversion you press ur calculator and you get 1.28
Answer:
6 coins
Step-by-step explanation:
For every 5 coins Carmen recieves, she gives off 2 to her brother, leaving her with 3 coins, 3x3=9, 2x3=6
Answer:
105.12 ft^2
Step-by-step explanation:
Area of a rectangle: bh
In this case 8*10.... so area of the rectangle is 80
Area of a circle: pir^2
Half it for a semicircle.
so 1/2 pi r^2
radius is 4 cuz its half of 8.
so 1/2(3.14)(4^2)=(0.5)(3.14)(16)=25.12
Now add up 80+25.12
Total is 105.12
Hope I helped :)
3. yes because 15 divided by 5 and 27 divided by 9 both result in the same answer; 3.
4. No because 3/4 is not a whole number, while 4/3 is. For this to be an equivalent ratio, the second number would have to be something like 6/8.
