Someone help me with #12

First, [tex]y=7x[/tex] and when we plug in the point we get [tex]-8=7a\implies a=-\frac{8}{7}[/tex].

Hope this helps :)

Answer:

[tex] {f}^{ - 1} (x)= - \frac{4}{3} x + 8[/tex]

Step-by-step explanation:

[tex]f(x) = - \frac{3}{4} x + 6[/tex]

[tex]y = - \frac{3}{4} x + 6[/tex]

[tex]x = - \frac{3}{4} y + 6[/tex]

[tex] - \frac{3}{4} y + 6 = x[/tex]

[tex] - 3y + 24 = 4x[/tex]

[tex] - 3y = 4x - 24[/tex]

[tex]\boxed{\green{ {f}^{ - 1} (x)= - \frac{4}{3} x + 8}}[/tex]

Step-by-step explanation:

Symbolic form involves using symbols to represent statements. The symbolic form of the given sentence is p v q

Given that:

[tex]p \to[/tex] "Inga has two aces in her hand."

[tex]q \to[/tex] "Inga has a full house."

The given sentence "Inga has either two aces in her hand or she has a full house." can be represented as:

Either p or q

In symbolic form, either/or is represented as: v

So, the representation of either p or q is: p v q

Answer:

y= -3x+4

Step-by-step explanation:

x+12=3y

(x+12)/3 = y

slope =

[tex] \frac{1}{3} [/tex]

the new slope = -3

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b

4 = -3×(0) + b

b= 4

so y= -3x+4

Answer:

y = 3/4x + 19/2

Step-by-step explanation:

m = 3/4. point (-6,5)

Point slope form:

y-5=3/4(x- -6)

y -5 = 3/4x + 18/4. 18/4 = 9/2

Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

y = 3/4x + 19/2

We have an algebra problem.

We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.

The information given is:

The pickup can travel 45 miles on 3 gallons of gas.

To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)

This is:

r = (45 miles)/(3 gallons) = 15 miles/gallon.

Now that we know this, the number of gallons needed to travel 30 miles is given by:

N = (30 miles)/(15 miles/gallon) = 2 gallons.

N = 2 gallons.

The pickup needs 2 gallons to travel 30 miles.

Step-by-step explanation:

1) Perimeter = 2(l + w)

Perimeter = 2(94 + 64)

Perimeter= 2(158) = 361 cm

2) Fabric required = Area

Area = l × b

Area = 94 × 64

Area = 6016 cm²

The measurements of a rectangular tablecloth are 94 cm and 64 cm.

How many cm does the perimeter of the tablecloth measure?

Therefore, the perimeter of the tablecloth is 316 cm.

How many cm of fabric were used to make it?

Therefore, the fabric is 6,016 cm².

Step-by-step explanation:

The midpoint formula is

[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]

Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.

The points are

(-5,-4)

(-3,3) So the midpoint is

[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]

Which gives us

[tex] - 4 \: and \: - 0.5[/tex]

So the midpoint is

(-4,-0.5)

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

mark me brainliest plz

Answer:

[tex]d = a_{2} - a _{1}[/tex]

d is the common difference

a1 is the first term, a1 = 27

a2 is the second term, a2 = 11

substitute:
