Write an equation of the line in slope intercept form

Answers

Answer: y = x + 2 OR f(x) = x + 2

Step-by-step explanation:

Calculating slope:

Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.

Finding y-intercept:

Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).

Write Equation:

y = mx +b

y = 1x + 2

y = x + 2 (your final answer)

The figure below depicts a triangle formed by the labeled
vertices. If each vertex point of the triangle is multiplied
by what would be the area of the resulting triangle?

Answers

9514 1404 393

Answer:

(b) 13.5

Step-by-step explanation:

The upper vertex would be ...

3/2(3, 3) = (4.5, 4.5)

and the right vertex would be ...

3/2(4, 0) = (6, 0).

The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...

A = (1/2)bh

A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

Rachel has 2/3 pound of snack mix. She eats 5/12 of the snack mix. How much of the snack mix did Rachel eat?

Answers

Answer: Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.

Step-by-step explanation:

Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..

If she ate [tex]\dfrac5{12}[/tex] of the snack mix.

Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]

[tex]=\dfrac56\times\dfrac13\\\\=\dfrac{5}{18}[/tex]

Hence, Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.

Robin baked 702 cookies.He sold them in boxes of 18. After selling all of the boxes of cookies for the same amount each, he earned $136.50.what was the cost of one box of cookies

Answers

Answer:

cost of a box is $3.5

Step-by-step explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is

Tyler sold = [tex]\frac{702}{18}[/tex]

Tyler sold = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

cost of each box = [tex]\frac{136.5}{39}[/tex]

cost of each box = 3.5

Thus, the cost of each box was 3.5

Determine whether the representation is proportional. y = -9x

Answers

Answer:

Yes, they are

Step-by-step explanation:

y = -9x

Here y∝ x

Where -9 is constant of proportionality

If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

t + 8/10 = 9/10
i need the value of t please

Answers

Answer:

1/10

Step-by-step explanation:

Answer:

t = 1

Step-by-step explanation:

When you cross multiply the equation becomes:

10(t+8)=10(9)

Now, solve for t.

10(t-8) = 10(9)

10t+80= 90

-80 -80

10t÷10 = 10÷10

t = 1

c. 19 + 12s < 75
b. 12 +195 2 75
d. 19 + 12s 275

Answers

Answer:

s = 3 He can only but up to 3 pairs of shorts, with 3 dollars left over.

Answer is 12 + 3s <= 75

$75 - $12 = $63

$63 / $19 = $3.3157894 about 3

$3 * $19 = $57

$57 + $12 = $69

$72 - $69 = $3
