Answer:

-5°F

Step-by-step explanation:

As, in 2 hrs = - 10°F

For 1 hr = - 10°F/2 = - 5°F

So, answer = - 5°F

It is 8/10 mile from liz's house to the market. Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the
Nina [5.8K]

Answer:

The equation that represents Liz's walk is:

5x + 3 = 4

Step-by-step explanation:

Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the market.

Let Liz's walk after that break be x mile.

Before the break, she had walked 6/10 miles. Adding these distances, she had walked a total of (x + 6/10) miles.

Because it is 8/10 miles from Liz's house to the market, all the walks she had to do to get to the market is 8/10 miles.

That is,

(x + 6/10) is the same as 8/10.

x + 6/10 = 8/10

Multiplying by 10, we have

10x + 6 = 8

Dividing by 2 gives

5x + 3 = 4

And this is the equation we wish to write.

Y=x2+3x+2 y=x2+5x-4 solutions
Klio2033 [76]

Answer:

 Slope = 1

 x-intercept = 2/1 = 2.00000

 y-intercept = 2/-1 = -2.00000

Step-by-step explanation:

Pulling out like terms :

2.1     Pull out like factors :

  -2x + 2y + 4  =   -2 • (x - y - 2)

Equation at the end of step  2  :

 -2 • (x - y - 2)  = 0

Step  3  :

Equations which are never true :

3.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Equation of a Straight Line

3.2     Solve   x-y-2  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x-y-2  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 2/-1 so this line "cuts" the y axis at y=-2.00000

 y-intercept = 2/-1  = -2.00000

Calculate the X-Intercept :

When y = 0 the value of x is 2/1 Our line therefore "cuts" the x axis at x= 2.00000

 x-intercept = 2/1  =  2.00000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -2.000 and for x=2.000, the value of y is 0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.000 - (-2.000) = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

    Slope     = 1

Geometric figure: Straight Line

 Slope = 1

 x-intercept = 2/1 = 2.00000

 y-intercept = 2/-1 = -2.00000

How many boys are in the choir​
Dafna11 [192]

9514 1404 393

Answer:

  D.  210

Step-by-step explanation:

If b is the number of boys in the choir, the ratio of boys to girls is ...

  b/150 = 7/5

  b = 150(7/5) = 30(7) = 210

There are 210 boys in the choir.
