Which of the following is a correct interpretation of the expression -4 + 13−4+13minus, 4, plus, 13?
MaRussiya [10]

the sum between negative 4 and 13, this can be tought as:

  • Stepping on -4 and moving 13 units to the right.
  • Stepping on 13 and moving 4 units to the left.

<h3>Which is the interpretation of the given expression?</h3>

The expression is just the sum:

-4 + 13

So we have the sum between negative 4 and 13, this can be tought as:

  • Stepping on -4 and moving 13 units to the right.
  • Stepping on 13 and moving 4 units to the left.

Now, none of the written options (a, b, and c) depict any of this, so I assume that the correct option is the one that you did not write, which is option D.

vekshin1

Answer:

1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5

Step-by-step explanation:

So since you are only buying 1 soda and you are buying multiple bags of Cheetos so you are able to use you debit card and meet the requirement of at least $5, you can make the inequality:

1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5

where x is the number of bags of Cheetos.

MArishka [77]
1 hour each day is used for test
so 8-1=7 used per day

so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical

4*5=20=private
2*15=30=research
1*4=40=commercial


20+30+40=90

percent from commercial
40/90=0.44444444444≈44.44% about 44%

Write an equation for each linear function described. Show your work. The graph of the function passes through the point (2,1),
svp [43]

Step-by-step explanation:

As

  • The graph of the function passes through the point (2,1), and
  • y increases by 4 when x increases by 1.

so

x             y

2             1

3             5

4             9

5             13

6             17

and so on

From the table:

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(2,\:1\right),\:\left(x_2,\:y_2\right)=\left(3,\:5\right)

m=\frac{5-1}{3-2}

m=4

As the slope-intercept form of the line is

y=mx+b

putting m=4 and any point, let say (2, 1) to find y-intercept 'b'.

1=\left(4\right)2+b

8+b=1

8+b-8=1-8

b=-7

So putting b=-7 and m=4  in the slope-intercept form of the line

y=\left(4\right)x+\left(-7\right)

y=4x-7

Therefore, the equation for the linear function will be:

y=4x-7
