Okay here’s an example:

10 divided by -5

You can do -5 times what equals 10? And count by 5 to 10, (5, 10)
Only 2 numbers here
So the answer is positive 2.
10 divided by -5= 2

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please help me!!!
dusya [7]

Answer:

B

Step-by-step explanation:

The red graph is a horizontal translation of 5 units left followed by a reflection in the x- axis.

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

The black graph is shifted 5 units left, thus

f(x) → f(x + 5)

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Note that the y- coordinate of the image is the negative of the original

Note also that \frac{y}{-1} = - y, thus

\frac{y}{-1} = f(x + 5) → B

Write the equation in slope intercept form. what are the slope and y-intercept?
Leno4ka [110]
Slope intercept is basically solve for y
y=mx+b
m=slope
b=yintercept

-3x-10y=7
add 3x to both sides
-10y=3x+7
divide both sides by -10
y=-3/10x-7/10

slope is -3/10
yintercept is -7/10 or at point (0,-7/10)

Allie bought a 5-pound bag of trail mix. She gave 12 ounces of trail mix to Justin. Then she put the rest of the trail mix into
trapecia [35]
To solve this problem, you will first want to convert 5 pounds into ounces. To do this, first determine how many ounces is in 1 pound.

There are 16 ounces in 1 pound, so to convert 5 pounds into ounces, you simply have to multiply 5 × 16. This will give you 80 ounces total.

Allie give 12 ounces away, so you must first subtract 12 ounces from your total (80 ounces). 80 - 12 gives us 68 ounces.

Allie then divides the trail mix up into 4 ounce portions. To figure out how many small bags she can make, you simply divide your new total (68 ounces) by 4. 

68 ÷ 4 = 17

Allie made 17 small bags.

PLEASE HELP WITH EXPLAINING I WILL MARK BRAINIES!!!
Drupady [299]

Answer: 3 mph

Step-by-step explanation:

1. 1/2 mph for 1/2 an hour as they said, meaning that they would've walked for 3 miles kn an hour.

2. 4 and 1/2 miles.

3 + 1 2/4. = 4 1/2

3. 1 3/4 hours.

3 + 2.25 = 5.25

3 x .75 = 2.25

3 miles per hour.

There are 30 blue balls, 40 red balls, and 30 white balls in a bag of balls. What is the conditional probability of choosing a b
natulia [17]

Answer: So, the probability will be

P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}

Step-by-step explanation:

Since we have given that

Number of blue balls =30

Number of red balls = 40

Number of white balls = 30

Since there are 100 balls in total ,

As we have given that there is no white ball chosen.

So, only 70 balls are left with us , from which we choose a blue ball

So, the probability will be

P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}
