Answer:
negative 21/9 times negative 18/7 is 6
Step-by-step explanation:
The phrase negative 21/9 times negative 18/7 can be written mathematically as
Lets first convert the fractions into decimal values
= -2.33
= -2.57
Now on simplyfying
=>
=> 5.988
=>6 (rounding off)
We will get a positive value because the multiplicative law states that the product of two negative number is positive
Answer:
x intercepts -sqrt(5), + sqrt(5)
y intercept -5
Step-by-step explanation:
y = x^2 -5
to find the x intercept set y=0 and solve for x
0 = x^2-5
add 5 to each side
5 = x^2
take the square root of each side
+- sqrt(5) = sqrt(x^2)
x = +-sqrt(5) there are 2 x intercepts since it is a quadratic
to find the y intercept set x=0 and solve for y
y = 0-5
y = -5
y+43°= 180°( straight angle)
=>y= 180°-43°
=>y=137°
The sum of 14 and a number is 14+x
we know that this equals 17, so: 14+x=17.
Let's substract 14 from both sides:
x=17-14
x=3
so the number is 3.
Answer:
It is 6.8
