Answer:

4

Step-by-step explanation:

How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )

We know that each cousin appear 2 or 3 times overall.

If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos

If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos

We know there's exactly 5 cousins per photo...

so we have to find a multiple of 5 cousins/photos that is between 16 and 24.

The only possibility is 20 cousins/photos. 20 / 5 = 4 photos.

What is the value for X??? WILL GIVE BRAINLIEST!!!

nexus9112 [7]

Answer:

x = 1.5

Step-by-step explanation:

First, we distribute (get rid of parentheses):

6x - 3 - 3x = 5 - x - 2

Then, we simplify:

3x - 3 = 3 - x

Then, we combine like terms:

3x + x = 3 + 3

Then, we simplify again:

4x + 6

Finally, we divide 4 on both sides:

We got x = 1.5

Hope this helps!

2x^2-5x+1=0 solve using quadratic formula

Gnesinka [82]

Answer:

x=(5±√17)/4, or x ≈ 2.281 and 0.219

Step-by-step explanation:

$2x^{2} -5x+1\\$

plug into quadratic formula

$5+- \sqrt{(-5)-4(2)(1)}/2(2)$

simplify

$5+-\sqrt{25-8} /4$

$\frac{5+-\sqrt{17} }{4}$ ≈ 2.281 and 0.219

PLS HELP Given the following table with selected values of the linear functions g(x) and h(x), determine the x-intercept of g(h(

kiruha [24]

Using linear and composite functions, it is found that the x-intercept of g(h(x)) is $x = -\frac{5}{6}$ , given by option B.

-------------------------------

The equation of a line is:

$y = mx + b$

In which:

m is the slope.
b is the y-intercept.

Function g:

Two of the points are (-6,16) and (-4,10).
The slope is given by <u>change in y divided by change in x</u>, thus:

$m = \frac{10 - 16}{-4 - (-6)} = -3$

Thus:

$g(x) = -3x + b$

Point (-4,10) means that when $x = -4, g(x) = 10$ , and we use this to find b, so:

$10 = -3(-4) + b$

$12 + b = 10$

$b = -2$

Then

$g(x) = -3x - 2$

Function h:

Two of the points are (-6,-11) and (-4,-7).
The slope is:

$m = \frac{-7 - (-11)}{-4 - (-6)} = \frac{4}{2} = 2$

Thus:

$h(x) = 2x + b$

Point (-4,-7) means that when $x = -4, h(x) = -7$ , and we use this to find b, so:

$-7 = 2(-4) + b$

$-8 + b = -7$

$b = 1$

Then

$h(x) = 2x + 1$

The composite function is:

$g(h(x)) = g(2x + 1) = -3(2x + 1) - 2 = -6x - 3 - 2 = -6x - 5$

The x-intercept it the zero of the function, thus:

$-6x - 5 = 0$

$6x = -5$

$x = -\frac{5}{6}$

Which is option B.
