Answer:
x≤−4 or x≥7
Step-by-step explanation:
To help solve this, we need to use the slope formula.
(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.
We will use points (-3, 1) and (-17, 2).
y1 = 1
y2 = 2
x1 = -3
x2 = -17
Let's plug these into our formula.
(2) - (1) / (-17) - (-3) = 1 / - 14
The slope is 1 / -14
The answer is 17
1.mutiply 1 and 4 in the brackets
2.subtract 8 and 4=4
3.multiply 2 and 4=8
4.8+9=17
To help use the Rule GEMDAS
G=Grouping
E=Exponents
M=Multiply
D=Divide
A=Addition
S=Subtract
He will have a 21.95 long strip of wood. How you can double check is by doing this:
You can subtract 25.5 from 72, to get 46.5. Next, subtract 15.3 from 43.5, to get 31.2. Finally, subtract 9.25 from 31.2 to get your final answer: 21.95.
Hope this helps, and good luck!!
Answer:
The smaller number is: 8
The bigger number is: 20
Step-by-step explanation:
Ok let's say the two numbers are x and y.
x is the smaller one, and y is the bigger one.
This is the equation to find x:
x + 4y = 88
x + y = 28
x - x + 4y - y = 88 - 28
3y = 60
y = 20
x + 20 = 28
x = 8
