Answer:
See explanation below (type a 1 (one) in each box)
Step-by-step explanation:
Notice that by using the exponent notation and properties, the given exponents can be re-written and simplified as shown below:
As you seem to have found. Well done!
What you are expected to do, is to type the coefficient that goes in the numerator (in your case a "1", and in the box below, the exponent that x has in the denominator (in your case also a "1").
So please complete the question as shown below typing a "1" in each box:
Let x = the first numberLet y = the second number x + y = 23 eq1 y = 23- x
xy = Product eq2
Substitute eq1 into eq2. Lets get eq2 in terms of x.
Product = x(23 - x)Product = - x2 + 23x
we must find the vertex has coordinate (h, k). h = -b / 2a where:a = -1b = 23
h= -23 / -2 = 11.5
<span>x = 11.5
</span>Substitute this value of x into eq1 to find y. y = 23 - xy = 23 - 11.5y = 11.5
<span>The two numbers that will give the largest product possible are 11.5 and 11.5.</span>
Answer:
Third one
Step-by-step explanation:
<u>Two </u>things to solve 3x+9 <= 15
3x <= 6
<u> x <= 2</u>
<u> and</u> - (3x+ 9) <= 15
- 3x - 9 <= 15
- 3x <= 24
3x >= -24
<u> x > = - 8 </u>
<u />

<u>s o -8 <= x <= 2 </u>
Answer:
Slope= 2 / 10 = 1 / 5 = 0.2
y-intercept= (0, -4/5) or (0, -0.8)
Step-by-step explanation:
I’m pretty sure it’s 20(4+5)
