1000x-100m 1000x is the the staring amount and the m is the amount you take out a month
That's a lot of questions. First, they're asking for how much each person pledged. Ivan said he would give $4.25, plus $1.25 per mile. As an expression, that would be 1.25m+4.25 . Vicky said that she would give $5.75, plus $.75 per mile, which would be .75m+5.75 . The second problem asks you to add the two, so add 1.25m and .75m to get the total amount she would earn per mile, which is $2. If I got paid $2 for every mile I biked, I would bike a marathon. Then add the flat payments of $4.25 and $5.75, and you get $10. So, the final equation would be 2m+10.
The last question is asking for you to find an equivalent proportional expression. To find this, you can just dividing by the greatest common factor of the two numbers. I got 2, so the equation would be 1m+5.
Answer:
1: 37.5%
2: C.p= 12×25= 300
S.p= 12×28= 336
profit%=336-300×100/300=12% ansr..
3: Therefore, Mr. Arsalan sold the plot at Rs 129600.

Answer:
h=55.4 mm
Step-by-step explanation:
Area of a triangle = 
where b is base and h is height
now just plug and chug
227.14 = 8.2h/2
227.14=4.1h
h=227.14/4.1
h=55.4
check answer:
55.4 * 8.2 /2 = 227.14, as proven by my calculator
The equation given is:
y = -7x^2 - 4x + 3
(1) The x intercept occurs at the point that has y = 0, therefore:
y = -7x^2 - 4x + 3
0 = -7x^2 - 4x + 3
(7x-3)(x+1) = 0
either x = 3/7 ......> the point is (3/7 , 0)
or x = -1 ......> the point is (-1,0)
(2) The y-intercept occurs at the point that has x = 0, therefore:
y = -7x^2 - 4x + 3
y = -7(0)^2 - 4(0) + 3
y = 3 ............> the point is (0,3)
