NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What is the slope of the line above?

A. - 2/3


B. - 3/2


C. 2/3


D. 3/2

Answer:

1. n = 1/2

2. m = 5/3 or 1 2/3

3. a = 1/4

4. x = 27/8

5. x = 13/6

Step-by-step explanation:

I'm just going to explain step 5 as that is what you specifically needed help with.

First, simplify the second term of the equation:

-6(2.5x-3)

= -15x + 18

(this was done by multiplying -6*2.5x which is 15x and -6(-3) which is 18)

Now, add this simplified second term back to the first term:

3x + 8 - 15x + 18

(the parentheses are unnecessary now because it is all just addition and subtraction, so the order doesn't matter)

Simplify:

-12x + 26 = 0

= -12x = -26

= x = -26/-12

=   x = 13/6

Answer:

[tex]-4x^2-x-19=0[/tex]

Step-by-step explanation:

Standard Form:

[tex]ax^2+bx+c=0[/tex]

Solve:

[tex]-4x^2-19=x[/tex]

Subtract x from both sides, then make standard form:

[tex]-4x^2-x-19=0[/tex]

Answer:

the desired equation is y = (-3/4)x + 7

Step-by-step explanation:

If you start at (0, 7) and move along the line to (4, 4), you'll see that x increases by 4 (this is the 'run') and y decreases by 3 (this is the 'rise').  Thus, the slope of this line is m = rise/run = -3/4.

Let's use this m = -3/4 and the point (0, 7) to write the equation of this line.

(0, 7) is actually the y-intercept.

Thus, the desired equation is y = (-3/4)x + 7.

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

Explanation:

The two items given

tells us that he spends 4*1.10 dollars on just the main course items. So that's why choice A is true.

-----------

From part A, we know that Juan spends 4*1.10 = 4.40 dollars on just the main course items. We also know the total cost of the meal is $9.80

This leaves 9.80 - 4.40 = 5.40 left over

Meaning that $5.40 is spent on dessert and drinks

The equation in part B is close, but the 4.40 should be 5.40 instead.

Choice B is false

-----------

"The dessert costs 50 cents more than the drink" means

r = d+0.50

Whatever the drink costs (d), we add on 50 cents or $0.50 to get the cost of the dessert (r). This is why choice C is false.

-----------

The system of equations we have so far is

[tex]\begin{cases}5.40 = d+r\\r = d+0.50\end{cases}[/tex]

Start with the first equation, plug in r = d+0.50, and solve for d

5.40 = d+r

5.40 = d+d+0.50

5.40 = 2d+0.50

2d+0.50 = 5.40

2d = 5.40-0.50

2d = 4.90

d = 4.90/2

d = 2.45

Each drink costs $2.45, so choice D is true because Juan only bought one drink.

-----------

Lets use this value of d to find r

r = d+0.50

r = 2.45+0.50

r = 2.95

Each dessert costs $2.95, making choice E true as well (since he only bought one dessert).

Answer:

6 hours

Step-by-step explanation:

$25 + $7.50x = 70

first subtract the flat fee of 25 from 70 to get $45.

then divide 45 by $7.50 to get the total hours spent

45 divided by 7.50 is 6

Hope this helps!

[tex]y + 7 = - \frac{2}{3}(x + 6) \\ [/tex]

[tex]y + 7 = - \frac{2}{3}x - 4 \\ [/tex]

Subtract sides -7

[tex]y = - \frac{2}{3}x - 4 - 7 \\ [/tex]

Thus ;

[tex]y = f(x)= - \frac{2}{3}x - 11 \\ [/tex]

So the correct answer is (( A )) .

13. c

Answer:

7. C: 80

8. D: 100

9. C: 80

Step-by-step explanation:

each line equals 180

where H is at, has a 100 above it.

that equals one angle, which is 100. That line has 2 angles at equal 100 since they are one opposite sides of each other.

you subtract 180-100= 80. That's where you get ur 80 angle from. Hope this helps, I'm bad at explaining stuff

Answer:

y=−15

Hope this helps! Please mark Brainliest!

Answer:

y = -15

Step-by-step explanation:

5y + 2(11 - 4y) = 82 + y

open parenthesis

5y + 22 - 8y = 82 + y

-3y + 22 = 82 + y

add 3y to both sides of the equation

-3y + 22 + 3y = 82 + y + 3y

22 = 82 + 4y

subtract 82 from both sides of the equation

22 - 82 = 82 + 4y - 82

-60 = 4y

divide both sides by 4

-60/4 = 4y/4

-15 = y

Answer:

y = -1/4x + 4

Answer:

125

Answer:

A

Step-by-step explanation:

We have the expression [tex]k+(2k-10)[/tex]

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

[tex]\Rightarrow (-3)+(2(-3)-10)[/tex]

Multiply:

[tex]=-3+(-6-10)[/tex]

Subtract:

[tex]=-3+(-16)[/tex]

Add:

[tex]=-19[/tex]

Therefore, our answer is A.
