Which graph represents the function f(x) = |x + 3|?

Sophie [7]

Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.

But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.

Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).

What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.

So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.

How many real solutions does the equation 8x^2 − 10x + 15 = 0 have?

Nimfa-mama [501]

Answer:

The correct option is (A) No real solution.

Step-by-step explanation:

The expression provided is a quadratic equation.

$8x^{2}-10x+15=0$

The roots of a quadratic equation are:

$x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }$

Here,

a = 8

b = -10

c = 15

The conditions to determine real and complex roots are:

If $b^{2}-4ac$ then the quadratic equation has two complex roots.
If $b^{2}-4ac>0$ then the quadratic equation has two real roots.

Compute the value of $b^{2}-4ac$ as follows:

$b^{2}-4ac=(-10)^{2}-(4\times 8\times15)\\\\$

$=100-480\\=-380\\$

The equation has two complex roots.

Thus, the correct option is (A).

An amount of money 960gh was contributed by 80 students. If 714gh was contributed equally by 68 girls and the remaining amount w

VLD [36.1K]

Each girl contributed 10.50gh

Each boy contributed 20.50gh

These are further explained and computed below:

The measure of central tendency being tested here is the mean, in other words, the resulting average when the total amount contributed by girls or boys is divided by the number of girls or boys.

The fact that 68 of the 80 students are girls means that the remaining 12 students are boys because 80 minus 68 gives 12.

each girl's contribution=total girls' contribution/number of girls

each girl's contribution=714/68

each girl's contribution=10.50gh

Total boys' contribution=total contribution-total girls' contribution

Total boys' contribution=960-714

Total boys' contribution=246

each boy's contribution=Total boys' contribution/number of boys

each boy's contribution=246/12

each boy's contribution=20.50gh

Similarly, details on computing the contribution of each sex can be found in the link

The Ortiz family will travel from Indianapolis to Denver this summer. The driving distance between the two cities is 1,058 miles

lakkis [162]

A. Write and solve an algrebraic equation to find out how many gallons of gas they will use. Explain your steps.

let x = gallons of gas they will use
y = distance traveled

x = y/20
x = 1058/20 = 52.9 gallons of gas

B. Write and solve an algebraic equation to find out how many miles they will travel.

let x = distance traveled
y = gallons of gas used

x = 20y
x = 20(52.9)
x = 1058 miles

Hope this helps. Have a nice day.
