Hey um does anyone wanna help me?

Answer:

y=-3x-16

Step-by-step explanation:

y-y1=m(x-x1)

y-(-7)=-3(x-(-3))

y+7=-3(x+3)

y=-3x-9-7

y=-3x-16

Given:

The function is

[tex]h=3+25t-5t^2[/tex]

To find:

The values of t where h is 8 meters.

Solution:

We have,

[tex]h=3+25t-5t^2[/tex]

Putting h=8, we get

[tex]8=3+25t-5t^2[/tex]

[tex]0=3+25t-5t^2-8[/tex]

[tex]0=-5+25t-5t^2[/tex]

[tex]0=-5(1-5t+t^2)[/tex]

Dividing both sides by -5 and interchanging the sides, we get

[tex]1-5t+t^2=0[/tex]

[tex]t^2-5t+1=0[/tex]

Here, [tex]a=1,b=-5,c=1[/tex].

Using quadratic formula, we get

[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]t=\dfrac{-(-5)\pm \sqrt{(-5)^2-4(1)(1)}}{2(1)}[/tex]

[tex]t=\dfrac{5\pm \sqrt{25-4}}{2}[/tex]

[tex]t=\dfrac{5\pm \sqrt{21}}{2}[/tex]

It can be written as

[tex]t=\dfrac{5-\sqrt{21}}{2}[/tex] and [tex]t=\dfrac{5+\sqrt{21}}{2}[/tex]

[tex]t=0.20871215[/tex] and [tex]t=4.7912878[/tex]

[tex]t\approx 0.21[/tex] and [tex]t\approx 4.79[/tex]

Therefore, the required values of t are 0.21 and 4.79.

Answer: 48 days

Step-by-step explanation:

Given

Ant takes 6 days to consume  [tex]\dfrac{3}{8}[/tex] of an apple

Using unitary method

[tex]6\ \text{days}\rightarrow \quad \frac{3}{8}\ \text{of an apple}\\\\1\ \text{apple takes}\rightarrow \quad \frac{8}{3}\times 6=16\ \text{days}\\\\3\ \text{apples take}\rightarrow\quad 16\times3=48\ \text{days}[/tex]

Answer: Weight of the remaining block of wood =400g

Step-by-step explanation:

Total Weight of five(5) blocks = 3kg = 3000g

Weight of 4 out of the 5 blocks = 650x 4= 2600g

Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks

= 3000g-2600g

=400g

Answer: Translate 5 units to the right, 3 units down

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

Explanation:

The x+5 means we add 5 to each x coordinate. A point like (1,2) moves to (6,2) after adding on 5 to that coordinate. This visually means the point moves 5 units to the right.

The y-3 means we shift 3 units down because we subtract 3 from the y coordinate. So for example, the point (6,2) moves to (6,-1).

Overall, the rule [tex](x,y) \to (x+5, y-3)[/tex] means a point like (1,2) will move 5 units to the right and 3 units down to arrive at (6, -1). I recommend you try out more examples.

Answer:

$5.47

Step-by-step explanation:

You multiply 2 by 0.79. Then you add that result (1.58) to 3.89 and you get your answer.

Step-by-step explanation:

the three rational numbers equivalent to each of the following rational number:-

i) -2/5=-4/10,-6/15 and -8/20.

ii) 3/7=6/14,9/21_and 13/28

Answer:

1

Step-by-step explanation:

by using Pythagorean theorem we can find the 3rd side;

(5/13)^2 + (12/12)^2 = 169 / 169 = 1

the root of number one is also 1.

Answer:

Pizzas: $8, Breadsticks: $3

Step-by-step explanation:

1. Write an equation.

Let the variables p = price of pizzas, and b = price of breadsticks

The equation: 3p + 2b = $30 for the first customer. The equation: 4p + 3b = $41 for the other customer.

2. Use the Elimination Method.

 (4p+3b=41) x3 =  12p+9b=123

- (3p+2b=30) x4 = 12p+8b = 120

------------------------------------------------

                                     8b = 3

Pizzas: $8

Breadsticks: $3

Answer:

Step-by-step explanation:

kidney beans : all beans

440:660 (simplify by dividing each by gcf which is 2^2(5)11=220)

2:3

Answer:

440:660 OR Simplified 2:3

Step-by-step explanation:

You already had the two numbers for the ratio, they added the cranberry beans in the sentence like that to confuse you and draw you away from the real answer. All you needed to do was arrange the numbers into a ratio, and simplify.

These problems are meant to to be confusing, so to stay away from the confusing parts, just reread them and you'll get it correct 24/7!

Hope you get this right.

Answer:

Step-by-step explanation:

it's 7 b/c everything is  halved    

Answer:

A = 58

B =:25

Step-by-step explanation:

C = A + B

83 = 9x + 4 + 4x + 1

83 = 13x + 5

13x = 78

x = 78/13

x = 6

A = 9x + 4 = 9 x 6 + 4 = 58

B = 4x + 1 = 4 x 6 + 1 = 25

Answer:

2,600 crayons

Step-by-step explanation:

10 boxes in a carton

5 cartons

10x5=50

52 crayons in a box

52x10=2,600 crayons

:)

Answer:

2,600

Step-by-step explanation:

If there are 52 crayons in a box, and 10 boxes in each carton, we know that there are 520 crayons in one carton. (52 x 10) If Mr. Johnson ordered 5 cartons,

520 x 5= 2,600. So, he would get 2,600 crayons.
