How do I plot y=2x-4

Mathematics

The formula: y = mx + b
m = slope or rise/run
b = y-intercept

So, the y-intercept would be -4 and the slope would be 2.

First, you would need to find the y-intercept, -4.

Next, you would use the slope, 2, to find the coordinate. Remember, 2 = 2/1
You would rise 2 and run 1.

The coordinates to form a line would be (1,-2), (3,2), and (-1,-6). All you would need to do is draw a line through the coordinates.

I hope this helps!

Which expression can be used to model the phrase “the sum of three and a number”? 3+x x-3

Name 4 decimals whose sum is 2.35

Sever21 [200]

Answer:

The values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Step-by-step explanation:

Name 4 decimals whose sum is 2.35

Let us consider that

a be first decimal

b the second decimal

c be the third decimal

d be the fourth decimal

According to the condition, we have to determine

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

As we have to name 4 decimals whose sum is 2.35.

So, taking the certain values of a, b, c and d as

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

The sum of a, b, c and d will be:

$0.35+0.68+0.81+0.51=2.35$

Putting the values of a, b, c and d in the equation $a\:+\:b\:+\:c\:+\:d\:=\:2.35$ .

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

$0.35+0.68+0.81+0.51=2.35$

$2.35 = 2.35$

Therefore, the values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Y = x² + 6x + 3

olganol [36]

Vertex is at $\left(-3,-6\right)$

y-intercept is 3.

The parabola opens up.

Step-by-step explanation:

The graph of the equation is hereby attached in the answer area.

Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here( $x =-3$ ), is shown with the dotted line in the graph attached.

y-intercept is defined as the value of y where the graph crosses the y-axis. In other words, when $x=0$ . Putting

And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of $x$ in the given equation $y =x^{2} + 6x + 3$ . Here, co-efficient of

So, vertex is at $\left(-3,-6\right)$

y-intercept is 3.

The parabola opens up.

Bella is baking chocolate chip cookies for an event. It takes 3/5 of a cup of flour to bake 6 cookies. She uses 1 1/10 cups of f

Aleonysh [2.5K]

300 chocolate chips is 6 batches of 50 chips each

(300 chocolate chips = 6 batches @ 50 chips ea)

Each batch of 50 chips = 1.1 cups of flour

Therefore 6 batches @ 1.1 cups ea = 6.6 cups of flour

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

0.6 cups (3/5 cups) of flour makes 6 cookies

6.6 cups of flour is 11 times more than that.

(0.6 x 11 = 6.6)

So she can make 11 times as many cookies.

(11 x 6 cookies = 66 cookies)

Answer:

Bella can make 66 cookies

(minus the three cookies that SumDude ate)

Find the value of f(-2) for the function f(x) = 4x + 10. A. -3 B. -2 C. 2 D. 18

Morgarella [4.7K]

Step-by-step explanation: If f(x) = 4x + 10, then f(-2) is 4(-2) + 10

which simplifies to -8 + 10 or 2.

So f(-2) = 2.
