B
Apply distributive property 2(5 - 3x) multiply 2 * 5, and 2 * -3x, you will end up with 10 - 6x.
18.
C
5*2x = 10x
5*4y = 20
Have a great day, good luck!
Answer:
C
Step-by-step explanation:
5a - 3b^2 - a + b - 5 + 8a^2
8a^2 - 3b^2 + 4a + b - 5
X usually represents time in months, and when you say h(x) = 103, this is a constant function, flat all throughout as <span>x→∞</span>. For s(x), it represents a line with increasing value of s(x) as <span>x→∞</span> at a rate of 1.03 and intercept of -1 at s(x) axis. When you say "combine" to form a new function means the addition of the two given functions, that is, h(x) + s(x), say equal to g(x).
<span>g(x)=h(x)+s(x)=103+1.03x−1=1.03x+102</span><span>g(x)=1.03x+102
</span><span>The new function g(x) is the same as s(x) with respect to the rate of increase, equal to 1.03, except this time, the intercept is +102, g(x) is the shifted version of s(x), from -1 to +102 (due to h(x)=103). Her savings account in a bank will grow at a rate of 3% per unit of time (x), starting at a savings of 102 at x=0.</span>
Answer:
20/21
Step-by-step explanation:
2/3 + 2/7
Get a common denominator of 21
2/3*7/7 = 14/21
2/7*3/3 =6/21
14/21 + 6/21
20/21
LW < = A (thats less then or equal to)
W = x
L = x + 18
A = 175
x(x + 18) < = 175
x^2 + 18x - 175 < = 0
(x + 25)(x - 7) < = 0
x + 25 < = 0
x < = -25.....extraneous solution...not ur answer
x - 7 < = 0
x < = 7 <==
so anything less then or equal to 7 can be a possible width
