Answer:
y-intercept is 1
Step-by-step explanation:
We need to find the equation of the line first.
<h3>Gradient</h3>
The gradient is found using the formula:
So the equation is y = 
x + c
<h3>Finding c</h3>
To find c we need to substitute the value of x and y into the equation:
-1 = 
+ c
-1 = -2 + c
1 = c
And c is the y-intercept so it is 1
Use desmos it’s free and you just put in the problem and it puts it on a graph for you
Assuming that there is supposed to be a + sign in front of the 2 and 4; the answer is as follows.
3(x+2)+4(x-5)=10
3x+6+4x-20=10
7x-16=10
7x=16
x=2 2/7
Hope this helps :)
The original length of a side was 13m
I got this by
taking 3m and * it by 4 because thats how many sides there are then
I got 12 so I subtracted 12 from 64 i got 52
so i divided the 52 by 4
which is
13
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
