Answer:
10x^2 -18
Step-by-step explanations
since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
The only true inequality is <u>-3 1/2 > -4.5</u>
Answer:
Step-by-step explanation:
Since the coordinates of P are (0, 1), this makes P the y-intercept of that line. The y-intercept exists where x = 0. And in the coordinate (0, 1), x does in fact equal 0.
Since the one coordinate given in Q is (?, 0), this means that Q is the x-intercept of the line. The x-intercept exists where y = 0. And in the coordinate (?, 0), y does in fact equal 0. So in order to solve for the x coordinate of Q, we plug in a 0 for y and solve for x:
3(0) - 4x = 12 and
-4x = 12 so
x = -3
Answer:
1) Product of 2 x 3/5 is 6/5 or 1 and 1/5.
2) 20/9 or 2 and 2/9
3) 15/8 or 1 and 7/8
4) 15/6 or 2 and 3/6 or 2 and 1/2
5) 6/4 or 1 and 2/4 or 1 and 1/2
Step-by-step explanation:
You multiply the whole number by the numerator (top number) and then divide the result by the denominator(bottom number). Afterward, simplify the fraction if you can, for example, 6/9. Both the numerator and denominator can be divided by 3. Therefore, the answer to that example is 2/3.
By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8
