One number is five more than another. If their sum is increased by nine, the result is 60. Find the numbers.
svlad2 [7]

Answer:

The two numbers are 23 and 28

Step-by-step explanation:

We are given that

X = Y + 5\\and\\(X+Y) + 9 = 60\\X+Y = 51\\(Y+5) + Y = 51\\2Y + 5 = 51\\2Y = 46\\Y = 23\\\\X = Y + 5\\X = 23 + 5\\X = 28

Find the equation of the linear function represented by the table below in slope-intercept form.
Ilya [14]

Answer:

the desired equation is y = x + 4.

Step-by-step explanation:

Slope is defined as m = rise over run.  Run is the change (usually an increase) in x, and rise an increase or decrease in y.

We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5).  Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.

Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:

5 = 1(1) + b, or b = 4.

Therefore the desired equation is y = x + 4.

What is an equation of the line that passes through the points (-1, 6) and<br> (-1, –5)?
miskamm [114]

Answer: 11x + 11

Step-by-step explanation:

This is two points equation. It could be done in various ways depending on the level of understanding of the topics. The formula goes thus

y - y₁         y₂ ₋ y₁                           y₂ ₋ y₁

------    =   ----------      or  y ₋ y₁ =    ---------  ˣ  ( x - x₁ )

x - x₁         x₂ ₋ x₁                           x₂ ₋ x₁

Where x₁ = -1, x₂ = -1, y₁ = 6, y₂ = -5. Now substitute for the values in the formula above and solve.

y - 6           -5 - 6       -11             -11

------      =   --------    =  ----      =    -----

x - (-1)         -1 - (-1)      -1 + 1          0

y - 6          -11

------    =    -----

x + 1           0   ,

Now we cross multiply to have a linear equation

0( y - 6 )  =  -11( x + 1 )

0   =   -11x - 11, now multiply by -1

The equation now becomes

11x + 11

Janet and her brother John went out to eat. Both paid the same amount. Janet got three burgers and left a $10 tip. John bought 4
lianna [129]

Answer:

Cost for 1 burger = 5 $

Amount spent by Janet  = 25$

Amount spent by John = 25$

Explanation:

Let the cost for burger be p.

Janet got three burgers and left a $10 tip

Amount spent by Janet  = 3 p + 10

John bought 4 burgers, but only left a $5 tip

Amount spent by John  = 4 p + 5

Both paid the same amount.

 So, we have  3 p + 10 = 4 p + 5

=> p = 5 $

So, cost for 1 burger = 5 $

Amount spent by Janet  = 3 x 5 + 10 = 25$

Amount spent by John  = 4 x 5  + 5 = 25$
