Answer:
He failed to flip the inequality
y ≤-1/2x-4
Step-by-step explanation:
-x-2y ≥8
Add x to each side
-x+x-2y ≥x+8
-2y ≥x+8
Divide by -2. Remember to flip the inequality
-2y/-2 ≤-1/2 x +8/-2
y ≤-1/2x-4
Shawn shaded the wrong side of the line.
Y is less than or equal to . He failed to flip the inequality
Answer:
Step-by-step explanation:
Sara's base pay is $80
(a) The 9t represents the additional amount of money that she earns if she gives instruction for t hours. 9 stands for $9 per hour
b)The term in the expression is t which stands for the number of hours that she instructs. The coefficient is 9 which stands for the hourly rate
c) The expression for 7 hours would be
We will substitute t into 80 + 9t. It becomes
80 + 9×7
d) in all, she will earn
80 + 9×7 = $143
(0, 3)
<span>-x + 3y=9
to figure out the y-intercept, you must put the equation into y-intercept form first: y = mx + b
</span><span>-x+3y=9
3y = x + 9
y = (x/3) + (9/3)
y = x/3 + 3

Answer:
dissect the trapezium into a square and triangle. since the triangle is a right angled one the base is 17-7=10cm
the height is found using Pythagorean theorem to be 24cm i.e 26²=x²+10²,x=√(676-100),x=√576,x=24cn
area of trapezium is (1/2)(a+b)h
a is the shorter side and b the longer side
(1/2)*(7+17)24
=288cm²
