Answer: C. Distribute 3/4 over (x-8)

Step-by-step explanation:

To solve any(technically most, but still...) algebraic equation you must isolate the variable.  In this case, the first step would either be to divide both sides of the equation by 3/4, or distribute 3/4 to x and -8, as you cannot modify the contents of the parenthesis without removing the 3/4.

Hope it helps and lmk if you further explanation <3 :)

Answer:

Composite

Step-by-step explanation:

70 is a composite number as it has factors other than 1 and itself.

It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.

Answer:

Pretty sure its 50

Step-by-step explanation:

if the height is 5, that would be multiplied by 2 because there are two identical sides. From the product, 10, you would need to get to 30, so you add 20. that means the other two identical sides are 10cm. 10x5 (length x width) is equal to 50.

Answer:

[tex]30 = 2 \times l + 2 \times b \\ 30 = 2 \times 5 + 2 \times b \\ 30 = 10 + 2b \\ 30 - 10 = 2b \\ 20 = 2b \\ = 20 \div 2 = 10 \\ area = l \times b \\ 5 \times 10 = 50cm {}^{2} [/tex]

Answer:

(i) 1/2

(ii) 3/20

Step-by-step explanation:

(i) given total number of white counters = 10

total outcomes = 20 (3+10+5+2)

so it's 10/20

by simplifying it we get 1/2

(ii) given total number of red counters = 3

so it's 3/20

Answer:

LH is perpendicular to HI

or

HI is perpendicular to LH.

You know they are perpendicular because there is a square symbol on angle H.

LH is perpendicular to HI

Here LHK is a triangle.

At H, angle is right angle. So the LH is perpendicular to the line HI.

Hence, LH is perpendicular to HI

Answer:

8

Step-by-step explanation:

There are two ways to solve this!

1. Use the Pythagorean Theorem

a^2 + b^2 = c^2

6^2 + b^2 = 10^2

100 - 36 = b^2

64 = b^2

8 = b

2. Shortcut using 3-4-5 triangles

A 3-4-5 triangle has to do with the ratios of each side.

In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

Problem 1

To find the y intercept, plug in x = 0 and simplify

f(x) = (x-2)(x+4)

f(0) = (0-2)(0+4)

f(0) = (-2)*(4)

f(0) = -8

We have x = 0 pair up with y = -8

The y intercept is (0,-8)

Answer: Choice D

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

Problem 2

(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.

The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.

Answer: C) Parabola opens upward

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

Problem 3

Answers:

Explanation:

Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).

Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.

Answer:

Step-by-step explanation:

7x+13 = 48

7x = 35

x = 5

Answer:

D. 5

Step-by-step explanation:

The angle should equal 48 degrees as it is congruent to the other angle labeled as 48 degrees.

So, we get the equation 7x + 13 = 48

Subtract 13 from both sides.

7x + 13 - 13 = 7x

48 - 13 = 35

We get 7x = 35

Divide by 7 on both sides.

7x / 7 = x

35 / 7 = 5

We get x = 5.

Answer:

the car travels faster

Step-by-step explanation:

Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2

600 divided by 2 = 300

Hank would have traveled 300 feet in 10 seconds

Andy traveled 300 feet at 12 seconds

Therefore Hanks car travels faster

Answer:

The car travels faster

Step-by-step explanation:

600 ft per 20 secs

How many feet in one sec?

600/20 = 30

Hank's car = 30 feet per second

300 feet in 12 sec

How many feet in one sec?

300/12 = 25

Andy's motorcycle = 25 feet per second

Given :

A bakery sells mocha cupcakes and vanilla cupcakes.

It sold 391 mocha cupcakes in a day.

15% of the cupcakes sold that day were vanilla.

To Find :

How many total cupcakes did the bakery sell that day.

Solution :

Let, total number of cupcakes bakery sell that day is x.

So, x - 0.15x = 391

0.85x = 391

x = 460

Therefore, total number of cupcakes bakery sell that day is 460 .

Answer: The length of the hypotenuse (c) is 5

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a & b are the legs (b is the base)

c = hypotenuse

a = 4

b = 3

a² + b² = c²

4² + 3² = c²

16 + 9 = c²

25 = c²

√c² = √25

c = 5

Answer:

3,675 people

Step-by-step explanation:

First row, a = 20

Common difference, d = 5

number of terms, n = 35

Sn = n/2 {2a + (n - 1)d}

= 35/2 {2*20 + (35 - 1)5}

= 35/2 {40 + ( 34)5}

= 17.5(40 + 170)

= 17.5(210)

= 3,675 people

The answer is actually 3675.

My reasoning: Plug it in and you shall see!

Answer:

first part: A. x^2+9x=36 and C. (x+9)(x)=36

second part: Width = 3 inches, Length = 12 inches

Step-by-step explanation:

"more than" implies addition, so you know you'll have 9+x in the equation you also know that you have to have the equation =36

also note (9+x is the length)

the equation for area of a rectangle is A=LW

so lets plug in what we do know

A = L W

36=(9+x)W

For the first part of the equation you're answer will be:

(x+9)(x)=36 AND x^2+9x (the reason for the second answer i listed is because when you multiple (x+9)(x) you get x^2+9x

when you solve for x it equals 3,

so the width (x) = 3 inches

and the Length (9+3) =12 inches
