Answer 1

Answer:

D it

Step-by-step explanation:

We have two equations, A quadratic and a linear equation.

The domain of a linear equation and quadratic equation is all real numbers but since it dealing with time we must make sure the roots or x-intercepts is positive.

Looking at the quadratic equation, we can use the discramnt formula to see if all roots are positve.

[tex]b {}^{2} - 4ac [/tex]

[tex] { - 6}^{2} - 4(1)(8.75)[/tex]

[tex]36 - 35 = 1[/tex]

The discramnt is greater than zero so there is two distinct real roots. So let check if they are positve

If you graph the equation, it intercepts at two positve roots so it is D

Answers

Answer:

x = 5 and y = -6

Step-by-step explanation:

The given equations are :

6x + 3y = 12 ...(1)

4x + y = 14 ...(2)

Multiply equation (2) by 3.

12x + 3y = 42 ...(3)

Subtract equation (1) from (3).

12x + 3y-(6x + 3y) = 42-12

12x+3y-6x-3y = 30

6x = 30

x = 5

Put th value of x in equation (2).

4(5) + y = 14

20 +y = 14

y = -6

So, the solution of the equations are x = 5 and y = -6.

Distribute property.
8x5= 40
8x2x= 16x
40-16x

Let's simplify this problem using the distributive property.

The first thing we want to do is change the minus to plus a negative.

Now distribute or multiply the 8 times

each of the terms inside the set of parentheses.

So we get 8(5) + 8(-2x) and this simplifies to 40 + -16x.

Solve the quadratic equation numerically (using tables of x- and y- values).

(x +2) (x + 3) = 12
a.
x = -1 or x = 3
c.
x = -6 or x = 1

Answers

Answer:

m<7 = 49°

m<8 = 41°

m<9 = 49°

m<10 = 41°

Step-by-step explanation:

Given :

m<7 ≅ m<9

m<8 = 41°

m<7 = 90° - m<8 (complementary angles)

m<7 = 90° - 41° (substitution)

m<7 = 49°

m<9 = m<7 (m<7 ≅ m<9)

m<9 = 49° (substitution)

m<10 = 90 - m<9

m<10 = 90 - 49

m<10 = 41°

Create a word problem that can be represented by the expression in number 4. –6 ÷ 1 1/3 ​

Answers

Answer:

I suppose that we want to use the expression in number 4.

The expression we need to use is:

6/(1 + 1/3)

This is:

"the quotient between the number 6 and the number 1 and 1/3"

We could write a problem like:

"We have 1 and 1/3 pounds of apples, and we have 6 grams of caramel that we want to divide evenly between all the apples. How much caramel we will have in each pound of apples?"

Then we need to divide the total amount of caramel by the total amount of apples, this is:

(6gr)/(1 + 1/3 lb) = (6/(3/3 + 1/3  )) gr/lb = (6/ 4/3) gr/lb = 6*(3/4) gr/lb

= 18/4 gr/lb =  (16 + 2)/4 gt/lb = 16/4 gr/lb + 2/4gr/lb = 4 gr/lb + 1/2 gr/lb

= (4 and 1/2) gr/lb

Jason wanted to place all 540 marbles in the 3 newly bought boxes. If he wants to

divide it in a ratio of 1:2:3, how many marbles would be in each box?


I really need your help please!!, thank you.

Answers

Answer:

The first box will have 90 marbles, the second 180 and the third 270.

Step-by-step explanation:

Division in a ratio of 1:2:3

1 + 2 + 3 = 6

So

The first box will have 1/6 of the marbles.

The second box will have 2/6 = 1/3 of the marbles

The third box will have 3/6 = 1/2 of the marbles.

First box:

One sixth, so:

(1/6)*540 = 540/6 = 90

Second box:

One third, so:

(1/3)*540 = 540/3 = 180

Third box:

One half, so:

(1/2)*540 = 540/2 = 270

The first box will have 90 marbles, the second 180 and the third 270.

each side of the hexagon measures 40 cm (which agrees with answer B)

Step-by-step explanation:

Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:

each side of the hexagon = 240 cm / 6 = 40 cm

Hexagons have 6 sides. 240 / 6 = 40 cm.
