<span>y= 1.5x - 4
y= -x
replace </span>y= -x into y= 1.5x - 4
y= 1.5x - 4
-x = 1.5x - 4
1.5x +x = 4
2.5x = 4
x = 1.6
y= -x
y = -1.6
answer: (1.6, -1.6) is the solution
Answer:
QR is tangent to circle P at point Q
=> RQP = 90 deg
=> RQP is right triangle.
=> Applying Pythagorean theorem for right triangle RQP:
QP^2 + QR^2 = RP^2
=>4^2 + QR^2 = RP^2
=> Option A is correct.
(4^2 + (4*
)^2 = 16 + 48 = 64 = 8^2)
=> Option C is correct.
(4^2 + 3^2 = 16 + 9 = 25 = 5^2)
=> Option D is correct
(4^2 + 2^2 = 16 + 4 = 20 = (2
)^2)
Hope this helps!

The formula is : #of overtime hours(h) *£16 + basic pay (b)
So, the easier way to put it is W=h*16+b
A: Wage= £284
A. W=h(9)*16+b(140)
=9*16+140
=144+140
=284
B: Overtime = 11
So, with this one, we work backwards
Using the same formula
W=h*16+b
We can fill in
300=16h+124
First, subtract 124 on both sides leaving
176=16h
Now we divide 16 on both sides, canceling out the right side
Leaving
11=h
Answer:
8
Step-by-step explanation:
I know because I got distracted question before
Subtract 12 from both sides
4(2x + 2) > 100 - 12
Simplify 100 - 12 to 88
4(2x + 2) > 88
Divide both sides by 4
2x + 2 > 88/4
Simplify 88/4 to 22
2x + 2 > 22
Subtract 2 from both sides
2x > 22 - 2
Simplify 22 - 2 to 20
2x > 20
Divide both sides by 2
x > 20/2
Simplify 20/2 to 10
<u>x > 10</u>
