Answer:

Step-by-step explanation:

The sum of 1/2 and y is equal to 3/4.

The equation to represent this is:

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

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:

D. It takes them more time to deliver packages because 157.3 x 1.25 = 196.625

Step-by-step explanation:

In the question, it states that this week it took the delivery drivers 1.25 times longer to deliver packages than last week, meaning that it took more time to deliver the packages this week than last week. With this, we can eliminate choices A and C.

Because it took them 1.25 times longer, then we can multiply 157.3 by 1.25 to find the correct sum.

157.3 × 1.25 = 196.625

The only answer choice that matches this information completely is choice D, so that is the answer.

hope this 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:

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! :)

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:

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.

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
