Answer:
5x+4
Step-by-step explanation:
The product of 4 and -7 implies we multiply these two numbers together. Added to -12 implies we add this product to -12.
Let's do the math...
(4 x -7) + (-12)
-28 + (-12) = -40
Answer:
x < 3 or x < 2
Step-by-step explanation:
|2x-5|<1
Using compound Inequality
(2x - 5) <± 1
Hence,
a) 2x - 5 < -1
2x < -1 + 5
2x < 4
x < 4/2
x < 2
b) 2x - 5 < +1
2x < 1 + 5
2x < 6
x < 6/2
x < 3
Therefore, x < 3 or x < 2
Answer:
B)15 yards
Step-by-step explanation:
We can solve this using Pythagoras theorem as
Let
Width of the pool= c
Length of diagonal of swimming pool =b
Length of the pool= a
c^2= b^2 + a^2
c^2 - b^2 = a^2
C^2 = 29^2 - 25^2
C^2=( 841-625)
C= √216
( Width of the pool)=15 yards
Hence, measurement is closest to the width of the pool is 15 yards
At those two x-intercepts, I know that x=2 and x=-2.
to get this, I know that there are two factors set to 0.
x+2=0 and x-2=0
so, if you multiply (x+2)(x-2)=y
then you will have standard form
x^2+2x-2x-4=y
y=x^2-4
