Which statement accurately describes the graph 2y=4x+8?
A
an increasing line that passes through (0, 4)
B
a decreasing line that passes through (0, 0)
C
an increasing line that passes through (0, 8)
D
a decreasing line that passes through (0, 2)

Answers

By rewriting the linear function we will see that the correct option is A.

"an increasing line that passes through (0, 4)"

Which statement describes the graph?

Here we have the linear function:

2y  = 4x + 8

We can rewrite it to get the function in the slope-intercept form:

y = (4x + 8)/2

y = 2x + 4.

So, the slope is positive, this implies that we will have an increasing line.

We also can see that the y-intecept is 4, this means that the line passes through the point (0, 4).

From that, we can conclude that the correct option is A.

Identify the vertex of the parabola?

Answers

Hi!

The vertex is the highest or lowest point on a graph, also known as the maximum/minimum. It is the turning point for the parabola.

In this case, it has a maximum, because the parabola points downward.

Using the graph, we can see the vertex is at point

(3, 4)

Answer:

(3,4)

Step-by-step explanation:

The vertex is a point that is the maximum or minimum of the parabola. (3,4) is the highest point on that parabola so it's a vertex

Find the quotient of 1/4 divided by 7

Answers

Answer: 1/4/7=1/28

You’re welcome good luck to whatever you’re working on. Give brainliest please for my answer.

the answer is indeed 1/28!

here’s why:
in order to divide fractions, you must multiply straight across. but, only when diving, you flip the 2nd fraction. we know that 7 has an invisible 1 under it, but since we’re dividing, we must flip it to 1/7.
so, you should now hove something that looks like this;

1 1
- x -
4 7

so simply, if multiplied correctly across, you should end up with 1/28.

1 x 1 = 1
7 x 4 = 28

Answer:

22 in

Step-by-step explanation:

volume of a right prism = area of base x height

Given:

volume = 352 in³area of base = 16 in²

⇒ 352 = 16 × height

⇒ height = 352 ÷ 16

⇒ height = 22 in

THIS IS URGENT. PLEASE HELP. given AC=30, find the value if x, and the length of BC

Answers

Answer:

The value of x is 4.8. The length of BC is 14.6.

Step-by-step explanation:

I combined the two expressions 3x+1 and 2x+5 to 5x+6=30

1. I subtracted 6 from 6 and 30 in the equations.

2. I was left with 5x=24

3. I then divide 5 from 5x and 24

4. I got x=4.8

To get the length of BC

2x+5

1. I multiplied 2×4.8

2. I got 9.6

3. I then add 5 to 9.6

4. I finally get the answer 14.6 which is the length of BC

Answer:

[tex]\overline{BC}=14.6[/tex]

Step-by-step explanation:

we know that

[tex]\overline{AC}=\overline{AB}+\overline{BC}[/tex]

so

[tex]30=3x+1+2x+5\\\\30=(3x+2x)+(1+5)\\\\30=(3+2)x+(1+5)\\\\30=5x+(1+5)\\\\30=5x+6\\\\5x+6=30\\\\5x+6-6=30-6\\\\5x+0=30-6\\\\5x=30-6\\\\5x=24\\\\\frac{1}{5}(5x)=\frac{1}{5}(24)\\\\\frac{5}{5}x=\frac{1}{5}(24)\\\\\frac{1}{1}x=\frac{1}{5}(24)\\\\x=\frac{1}{5}(24)\\\\x=\frac{24}{5}\\\\x=4.8[/tex]

and now we solve for BC

[tex]\overline{BC}=2x+5\\\\\longrightarrow x=4.8\longleftarrow \\\\\overline{BC}=2(4.8)+5\\\\\overline{BC}=9.6+5\\\\\overline{BC}=14.6[/tex]

so that's our answer

Answers

Answer:

13.1 cm² (nearest tenth)

Step-by-step explanation:

Use the sine rule for area of a triangle with 2 sides and an included angle (SAS).

Sine rule for area

[tex]\textsf{Area ABC}=\dfrac12ab \sin C[/tex]

(where [tex]a[/tex] and [tex]b[/tex] are the side lengths and [tex]C[/tex] is the included angle)

Given:

[tex]a[/tex] = 8 cm[tex]b[/tex] = 7 cm[tex]C[/tex] = 28°

[tex]\implies \textsf{Area}=\dfrac12\cdot 8 \cdot 7 \cdot\sin (28\textdegree)[/tex]

               [tex]=13.14520376...[/tex]

               [tex]= 13.1 \textsf{ cm}^2 \textsf{ (nearest tenth)}[/tex]

Use sine rule

Area:-

[tex]\\ \sf\longmapsto \dfrac{1}{2}(8)(7)sin28[/tex]
