Answer:
-3
Step-by-step explanation:
The value of f(-3) can be found at looking at the x-value of -3, then drawing a vertical line. If you look at the point where the vertical line hits th graph, you get the point (-3,-3)
The y-value is what we are looking for, which is -3.

Grace got a haircut for $26.95, bought three shirts on sale for $18.50 each and a pair of jeans for $48, and purchased two CDs for $18.50 each. Round each amount to the nearest ten dollars to find a reasonable estimate of how much Grace spent.
Answers
26.95 + 18.5 * 3 + 48 + 18.5 * 2
18.5 * 3 = 55.5
18.5 * 2 = 37
37 + 55.5 + 48 + 26.95 = 167.45
= $167.5

Hi!
I can help you with joy! :)
Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept)
Now, where does the graph touch the y-axis?
It touches the y-axis at (0,1)
Thus, the y-intercept is 1.

A bee farm can produce 1.24 L of honey every week. But during the last week of may, due to change of weather, the production was decreased by 420 ml.
How much honey (measured in ml) was produced during the last week of may?
Answers
Answer:

The ratio of centimeters on a map to distance in kilometers is 2 to 5.
If two cities are 16 cm apart on the map, what is the actual distance in kilometers between the two cities? You can use a double number line diagram to help you solve.
Answers
Answer: 40 kilometers
Step-by-step explanation: Since the word ratio is cm/km (centimeter/kilometer), and the number ratio is 2/5, you will have to create another set and put the 16 cm next to the 2 cm. So it would be 2/5=16/X. Now you have to find the value of x. First, you have to multiply 5 by 16, which is equal to 80. Now you divide it by 2 and you will get 40 kilometers as your final answer.

1. Find the indicated lengths:
2. Find the value of X:
3. Find the length of AC:
Answers
Answer:
so
Step-by-step explanation:
SO YOU HAVE TO FIND LENGTH OF THE TRIANGLE
Step-by-step explanation:
I just answered 1.
by using the principle of similar triangles (all angles are the same between the 2 triangles, and the ratio of a corresponding pair of sides is the same for all pairs of sides) we get
AB = 2×38 = 76
AC = 2×24 = 48
WX = CB/2 = 66/2 = 33
2.
the upper small triangle and the whole big triangle are similar triangles.
and we see the ratio of the legs is 1/2 (each leg of the small triangle is half of the leg of the large triangle).
therefore,
3x = 24/2 = 12
x = 12/3 = 4
3.
AC = 16
because the height of C splits the baseline precisely in half, it means that this is at least an isoceles triangle (both legs have the same length). therefore the answer.
AC = CB = 16.

Answer:
The factors are x-3 and x+2, and the roots are 3 and -2.
Step-by-step explanation:
x^2-x-6 can be factored in the following way:
(x-3)(x+2)
The factors are x-3 and x+2, and the roots are 3 and -2.
Factored form of an expression is writing it in the terms of multiplication of factors. The factors of given expression are: (x-3) and (x+2)
How to factorize a quadratic polynomial with single variable?Quadratic polynomial with single variables are expressible in the form
[tex]ax^2 + bx + c[/tex]
where x is the variable and a,b,c are constants.
Its factored form is
[tex]\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})[/tex]
For the given case, the expression given to us is [tex]x^2 - x - 6[/tex]
Comparing it with the standard form of quadratic expression [tex]ax^2 + bx + c[/tex], we get: a = 1. b = -1. and c = -6
Using the aforesaid formula, we get:
[tex]=\dfrac{1}{4a^2} \times (2ax +b-\sqrt{b^2 - 4ac})(2ax +b+ \sqrt{b^2 - 4ac})\\\\=\dfrac{1}{4}\times(2x -1 - \sqrt{1 +24})(2a -1 + \sqrt{1 + 24})\\\\=\dfrac{1}{4} \times (2x - 1-5)(2x - 1 + 5)\\\\=(x -3)(x+2)[/tex]
Thus, The factors of given expression are: (x-3) and (x+2)
