ANSWER :

∠D = y = 65 and ∠F = x = 45

Step-by-step explanation:

The linear function that you could use to find the number of weeks it would take to reach your goal is:

35n + 100 = 800.

A linear function is modeled by:

y = mx + b

In which:

From the table, we have that:

Hence the balance after n weeks is given by:

B(n) = 100 + 35n.

You will have $800 when B(n) = 800, hence the equation is:

35n + 100 = 800.

Answer:

D.  The graph of g is the graph of f shifted 2 units down.

Step-by-step explanation:

Transformations

f(x) - a :  vertical shift of "a" units down

f(x) + a : vertical shift of "a" units up

f(x - a)  : horizontal shift of "a" units to the right

f(x + a) : horizontal shift of "a" units to the left

If  g(x) = f(x) - 2

Then g(x) is f(x) shifted 2 units down.

Answer:

1500 mg is the least mass

Step-by-step explanation:

Lets convert them all to the same mass unit,

1500 mg to grams: 1500 mg / 1000 = 1.5 grams

13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams

30000 cg to grams: 30,000 cg / 100 = 300 grams

7428g no conversion needed!

1.5 grams, 13,200 grams, 300 grams, 7,428 grams

1.5 is the smallest number

Answer:

5% = 8

Step-by-step explanation:

Since 10% of a number is 16, multiply that by 10 to get 160. In order to get 5%, divide 10% (16) by 2 to get 8, which is 5% of 160.

======================================================

Explanation:

There are at least three ways to solve this.

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

Method 1:

We could graph y = (x-2)(x+10) using a tool like Desmos. Graph y = 13 as well which is a horizontal line.

Check out the screenshot shown below.

The parabola in red and the horizontal line in blue intersect at the locations (-11, 13) and (3, 13)

We only focus on the x coordinates of the intersection points.

Therefore, the two solutions are x = -11 and x = 3

The order of the solutions doesn't matter.

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

Method 2:

Expand things out and get everything to one side

(x-2)(x+10) = 13

x^2 + 10x - 2x - 20 = 13

x^2 + 8x - 20 - 13 = 0

x^2 + 8x - 33 = 0

From here we can use the quadratic formula

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-8\pm\sqrt{(8)^2-4(1)(-33)}}{2(1)}\\\\x = \frac{-8\pm\sqrt{64+132}}{2}\\\\x = \frac{-8\pm\sqrt{196}}{2}\\\\x = \frac{-8\pm14}{2}\\\\x = \frac{-8+14}{2} \ \text{ or } \ x = \frac{-8-14}{2}\\\\x = \frac{6}{2} \ \text{ or } \ x = \frac{-22}{2}\\\\x = 3 \ \text{ or } \ x = -11\\\\[/tex]

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

Method 3:

Instead of using the quadratic formula, we could factor.

To factor x^2+8x-33, we need to find two numbers that

Through trial and error, you should get 11 and -3

So,

x^2+8x-33 = 0

(x+11)(x-3) = 0

x+11 = 0 or x-3 = 0

x = -11 or x = 3

Answer:

Answer = 5.5

Step-by-step explanation:

The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,

181.5 = 6*s^2

Now we divide 6 by both sides to get

30.25 = s^2

Now we have to find the square root of both sides to get

5.5 = s

Hope that helps! :)

The value of x such that the hcf is 26 and the l.c.m is 1092 is 156

The numbers are given as:

182 and x

The HCF and LCM are given as:

HCF = 26

LCM = 1092

As a general rule;

The product of LCM and HCF of x and y equals the product of x and y

So, we have:

182 * x = 26 * 1092

Divide both sides by 182

x = 156

Hence, the value of x is 156

Answer:

  (a)  3 must be factored from 3x^2 + 9x

Step-by-step explanation:

The first step when rewriting a quadratic from standard form to vertex form is to factor out the leading coefficient from the variable terms.

__

  y = 3x^2 +9x -18 . . . . . . given

  y = 3(x^2 +3x) -18 . . . . . leading coefficient factored out

  y = 3(x^2 +3x +2.25) -18 -3(2.25) . . . . . complete the square

  y = 3(x +1.5)^2 -24.75 . . . . . simplify to vertex form

Answer:

302 1/10 is our fraction form more known to be a mixed number.

Step-by-step explanation:

Fraction form from decimal is to keep our 302 and make .1 a fraction.

This is because we already have a base/whole number and just need a fraction to make this decimal an improper fraction. 0.1 is equivalent to 1/10 because in order to get to 0.1 you need to move the decimal point 1 digit to the right. You could also do 1 divided by 10.

302 1/10 is our fraction form more known to be a mixed number.
