For number 33. you can solve for "x": 90+(7x+5)+(3x-5)=180; 90+10x=180;
10x=90; x=9.
If #peaches = x and #plums = y we can write the following equations:
x+y=15
0.89x + 0.39y = 8.85
and x and y are whole numbers.
converting the first to x=15-y and plugging it into the second, you get
0.89(15-y) + 0.39y = 8.85 =>
13.35 - 0.89y + 0.39y = 8.85 =>
4.5 = 0.5y =>
y = 9
so x = 15-9 = 6
She bought 9 plums and 6 peaches.
I can’t the picture can you post a other one
The slope-intercept form of line:
y = mx + b
The slope m = 0.5 and y-intercept b = 2. Therefore we have the equation:
y = 0.5x + 2.
It is a linear function. We need only two points to plot the graph.
We have y-intercept, therefore we have the point (0, 2).
Second point:
for x = -4 → y = 0.5(-4) + 2 = -2 + 2 = 0 → (-4 , 0)
