Answer:
15-9 will be greater
Step-by-step explanation:
Caroline wants to compare the expressions 15-9 and 9 (-15)
For us to know the result that is greater, we will have to check if the first value is less than or greater than the other. For example
If for a-b
a-b is greater if a>b
a-b is lesser if a<b
Given 15 - 9
Since 15 > 9, this means that 15-9 will be greater compare to 9-15
HELP ME PLZZZZZZZZZZ
Answer:
In both cases, we have similar figures.
This means that the shape of the figures is the same, but the size is different:
PQST is similar to STNR and to NRPQ
VUYZ is similar to YZWX and to VUWX
this means that, for example, in problem 18, the ratio between ST and NR must be the same as the ratio between PQ and ST. This happens because the measure increases by the same scale factor.
With this in mind, we can solve the problem:
18)
ST = 7.5
NR = 5.5
Then the quotient ST/NR is:
ST/NR = 7.5/5.5
And, as we said above:
PQ/ST = ST/NR
PQ/7.5 = 7.5/5.5
PQ = (7.5/5.5)*7.5 = 10.23
19) Here we should have:
YZ/VU = WX/YZ
Then:
22.9/35 = WX/22.9
(22.9/35)*22.9 = WX = 14.98

Answer:
(c) h(x) = (3x +4)(2x +1)
Step-by-step explanation:
The answer choices differ in the values they create for the last two terms of the trinomial. The last term (+4) is created by all of the choices except the first one.
The middle term (11x) is only created by the third choice:
(3x +4)(2x +1) = (3x)(2x) +(3x)(1) +(4)(2x) +(4)(1)
= 6x^2 +3x +8x +4
= 6x^2 +11x +4 . . . . matches the given h(x)

Step-by-step explanation:
The function f is such that f(x) = 2x/3x+5 The function g is such that g(x) = 3/x+4 Find fg(-5)
Answer:
[tex]f(g(-5)) = \frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{2x}{3x+5}[/tex]
[tex]g(x) = \frac{3}{x+4}[/tex]
Required
Find f(g(-5))
First, we calculate f(g(x))
[tex]f(x) = \frac{2x}{3x+5}[/tex]
Substitute g(x) for x
[tex]f(g(x)) = \frac{2g(x)}{3g(x) + 5}[/tex]
Substitute [tex]\frac{3}{x+4}[/tex] for g(x)
[tex]f(g(x)) = \frac{2*\frac{3}{x+4}}{3*\frac{3}{x+4} + 5}[/tex]
[tex]f(g(x)) = \frac{\frac{6}{x+4}}{\frac{9}{x+4} + 5}[/tex]
[tex]f(g(x)) = \frac{6}{x+4}/ (\frac{9}{x+4} + 5})[/tex]
Take LCM
[tex]f(g(x)) = \frac{6}{x+4}/ \frac{9+5x+20}{x+4}}[/tex]
[tex]f(g(x)) = \frac{6}{x+4}/ \frac{5x+29}{x+4}}[/tex]
Rewrite as multiplication
[tex]f(g(x)) = \frac{6}{x+4}* \frac{x+4}{5x+29}}[/tex]
[tex]f(g(x)) = \frac{6}{5x+29}[/tex]
Substitute -5 for x
[tex]f(g(-5)) = \frac{6}{-5*5+29}[/tex]
[tex]f(g(-5)) = \frac{6}{-25+29}[/tex]
[tex]f(g(-5)) = \frac{6}{4}[/tex]
[tex]f(g(-5)) = \frac{3}{2}[/tex]
PLEASE STOP STEALING MY QUESTIONS OMGG
Answer:
The answer is the last one: 9,4,1
Step-by-step explanation:
- Output means y
- Input means x
The question asks to input -4, 1, 4 to find the output value
If we input -4, the answer is:
y = - x + 5
y = - (-4) + 5
y = 4 + 5
y = 9
If we input 1, the answer is:
y = -x + 5
y = - (1) + 5
y = -1 + 5
y = 4
If we input 4, the answer is:
y = -x + 5
y = - (4) + 5
y = -4 + 5
y = 1
Hope it helps!

Answer:
1/ -6=12+1/3a
Rewrite the equation as 12+1/3a=−6.
12+1/3a= −6
Combine 1/3 and a.
12+a/3= −6
Move all terms not containing a to the right side of the equation.
a/3= −18
Multiply both sides of the equation by 3.
3⋅a/3=3⋅ −18
Simplify both sides of the equation.
a= −54
2/ -6 =12 -1/3a
Rewrite the equation as 12−13a=−6.
12−1/3a=−6
Combine a and /13.
12−a/3=−6
Move all terms not containing a to the right side of the equation.
−a/3=−18
Multiply both sides of the equation by −3.
−3⋅(−a/3)=−3 ⋅−18
Simplify both sides of the equation.
a=54

Answer:
y = 14°
Step-by-step explanation:
since we can see it is an isosceles triangle so
base angles of isosceles triangle are equal then
2x = 50°
50° + 2x + 5y + 10° = 180° { being sum of angles of triangle }
50° + 50° + 5y + 10° = 180°
110° + 5y = 180°
5y = 180° - 110°
5y = 70°
y = 14°

Can someone please answer my question Geometric Sequence:
3, 6, 12, 24, …
Answer:
48
Step-by-step explanation:
You multiply by 2 each time
I believe it is multiplying by 2 each time.
3 x 2 = 6
6 x 2 = 12
12 x 2 = 24
So if this was true to continue we would just multiply by 2....
24 x 2 = 48
48 x 2 = 96
96 x 2 = 192
192 x 2 = 384
384 x 2 = 768
and continue for as long as you need to go....
