A bakery used 38 pounds of flour to make French bread and

3

bagels. One loaf of French bread requires 2- pounds of flour,

4.

and one batch of bagels requires pound of flour. Let a

represent the number of loaves of bread and b represent the

number of batches of bagels. Which equation represents the

relationship between the number of loaves of French bread

and the number of batches of bagels that the bakery made?

?

Answers

Answer:

since we are not given the options, I will write down a few equations that represent the number of French bread loaves and bagels:

a = number of loaves of French breadb = number of bagelsavailable amount of flour = 38

2a + b ≤ 38

2a ≤ 38 - b

a ≤ (38 - b) / 2

a ≤ 19 - 0.5b

b ≤ 38 - 2a

b ≤ 2(19 - a)

Hopefully one of these equations is one of the choices given to you.

The graph of line g is shown below.



Which equation describes a line parallel to line g that has a y-intercept at (0, −1)?

Answers

Answer:

is the graph of y=-2x-1

The equation of line which is parallel to given line is , [tex]y=-\frac{1}{2}x-1[/tex]

Option H is correct.

Equation of line :

Given line is passes through points [tex](-4,6)[/tex] and [tex](4,2)[/tex]

Slope of given line is,

                  [tex]Slope=\frac{2-6}{4+4}=-\frac{1}{2}[/tex]

Since, all parallel lines have the same slope.

So that, slope of line parallel to given line is also equal to [tex]-\frac{1}{2}[/tex]

Equation of required is,

               [tex]y=-\frac{1}{2}x+c[/tex]

Since, line passes through point [tex](0,-1)[/tex]

We have to find the simplest ratio between length, breadth and the height.

Here,

Length = 10 cmBreadth = 15 cmHeight = 25 cm

Note:

Always check the units first.Then find the HCF of the numbers to simplify them into the simplest ratio.

So,

HCF of 10, 15 and 25 is 5. Cancelling with respect to 5.

Then, the ratio will be 2:3:5 (Option A)

Mr. Hernandez plotted the point (1, 1) on Han’s graph of y ≤ One-halfx + 2. He instructed Han to add a second inequality to the graph that would include the solution (1, 1).

Which equation could Miguel write?

y > 2x + 1
y < 2x – 1
y ≥ 2x + 1
y ≤ 2x – 1

Answers

The linear inequality that satisfies the point (1, 1) is y ≤ 2x – 1 option (D) y ≤ 2x – 1 is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The graph of the linear inequality is shown in the picture.

The point is (1, 1)

Take the equation:

y ≤ 2x – 1

Plug x = 1, y = 1

1 ≤ 2 – 1

1 ≤ 1  (True)

Thus, the linear inequality that satisfies the point (1, 1) is y ≤ 2x – 1 option (D) y ≤ 2x – 1 is correct.

Answers

Answer: 33 degrees

Step-by-step explanation:

We can find angles PQS and PSQ by using the base angle theorem, which states that the base angles of an isosceles triangle are congruent. Subtracting 48 from 180 we get 132, which dividing by 2 we get 66 degrees.

Now we can use the exterior angle theorem, which states that an exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle. In this case, we are saying that ∠QSP= ∠QRS+∠RQS. Both of these angles are congruent because of the base angle theorem as well. Dividing 66 by 2 we get 33 degrees. Thus, m∠QRS=33°

Consider these numbers, ordered from least to greatest. Negative 1.8, negative 1 and one-fourth, negative 0.2, blank, one-half, 90 percent A number line going from negative 2 to positive 1. Which values could correctly fill in the blank? Select all that apply. 10% 1 -0.1 -1 One-fourth

step-by-step explanation

On the number line, numbers increase from left to right.

The blank is between -0.2 and 1/2.

Only numbers greater than -0.2 and less than 1/2 can fill the blank.

Range = -0.2<x<1/2

From the values given,

1) 10% = 10/100 = 1/10 = 0.1

-0.2<0.1<1/2

2) -0.2<1

But, 1>1/2

3) -0.2<-0.1<1/2

4) -0.2>-1

5) -0.2<1/4<1/2

Therefore, only 10%, -0.1, and 1/4 can fill in the blank correctly because they satisfy the range -0.2<x<1/2
