If you solve the equationx - 3 = 7, what information will you have?​

Answers

Answer 1

Answer:

x=4

Step-by-step explanation:

both sides, add 7

Answer 2

Hey there!

“x – 3 = 7”

• FIRST: ADD by 3 on BOTH sides

• x – 3 + 3 = 7 + 3

• CANCEL out: –3 + 3 because that gives you 0

• KEEP: 7 + 3 because that helps us solve for your x-value

• NEW EQUATION: x = 7 + 3

• FLIP THE EQUATION: 7 + 3 = x

“Solve above and you have your answer!”

• ANSWER: x = 10 ☑️

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

Plz mark as Brainliest

A parabola has a maximum value of 4 at x= -1, a y-intercept of 3, and an x-intercept of 1. The x-intercepts are -3 and 1. So, The second graph is the right one.

We have given that,

A parabola has a maximum value of 4 at x = -1,

A y-intercept of 3, and an x-intercept of 1.

What is the maximum point of the graph?

The maximum value of a graph refers to the point on the graph where the y-coordinate has the largest value.

A maximum graph is one that represents the largest value of the y-coordinate on the graph.

So, The second graph is the right one.

Note that when x = 1, y (the maximum) is 4,

and that, The x-intercepts are -3 and 1.

Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of the bottle of milk did the calf drink

Answers

Answer:

[tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.

Step-by-step explanation:

Part of the bottle fed by the piglet = [tex]\frac{1}{5}[/tex]

Milk left in the bottle = 1 - [tex]\frac{1}{5}[/tex]

                                  = [tex]\frac{5-1}{5}[/tex]

                                  = [tex]\frac{4}{5}[/tex]

Milk drunk by the calf = [tex]\frac{3}{4}[/tex]th of the left part

                                     = [tex]\frac{3}{4}\times \frac{4}{5}[/tex]

                                     = [tex]\frac{3}{5}[/tex]th part of the bottle

Therefore, [tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.

Together, Ashley and Gabby watched a total of 14 hours of television over the weekend. Ashley watched 6 times as many hours as Gabby. How many hours of television did they each watch over the weekend? Write and solve a system of equations by using the substitution method. Be sure to define your variables.

Answers

Answer:

The number of times over the Weekend that:

Ashley watched TV = x = 12 hours

Gabby watched TV = y = 6 hours

Step-by-step explanation:

Let us represent:

The number of times

Ashley watched TV = x

Gabby watched TV = y

Together, Ashley and Gabby watched a total of 14 hours of television over the weekend.

= x + y = 14..... Equation 1

x = 14 - y

Ashley watched 6 times as many hours as Gabby.

x = 6y

Using substitution method

We substitute 14 - y for x

14 - y = 6y

14 = 6y + y

14 = 7y

y = 14/7

y = 2 hours

Solving for x

x = 14 - y

x = 14 - 2

x = 12 hours

Therefore:

The number of times over the Weekend that:

Ashley watched TV = x = 12 hours

Gabby watched TV = y = 6 hours

Han earns $33.00 for babysitting 4 hours. At this rate, how much will he earn if he
babysits for 7 hours. You may solve with any method but you must show your work.

Answers

First you do $33.00/4 to get $8.25. Take the 8.25 and multiply it by 7 to get $57.75

Step-by-step explanation:

First, you want to find the unit rate, or how much Han earns per hour

You can do this by setting up an equation

x= amount earned per hour

4x= 33          Initial equation

4x/4 = 33/4   Isolating the variable

x = 33/4 = 8 1/4 = 8.25    The unit rate

Now you want to set up a new equation to find out how much he makes for 7 hours

x= amount earned per hour

y = total amount earned

y = 7x    Initial equation

y = 7 ( 8.25)   Substitution

y = 57.75  The answer

Han earns $57.75 for every 7 hours

Checking the answer....

y = 7x

57.75 = 7x    Substitute y instead

57.75/7 = 7x/7

8.25 = x

Your answer should be correct

Hope this helps!!!

What is the length of DE in the image provided? (Please explain so I can understand in the future)

A. DE=4
B. DE=5
C. DE=6
D. DE=7

Answers

Answer:  D.  DE = 7

==========================================================

Explanation:

We have these three facts:

The arc markings on angles C and D indicate those angles are congruent. We can say that angle ACB = angle EDB.Another pair of congruent angles are angle ABC and angle EBD. These are vertical angles. Lastly, we have a pair of congruent sides AB and BE because of the tickmarks.

Those three facts allow us to use the AAS (angle angle side) congruence theorem to prove that triangle ABC is congruent to triangle EBD.

Then by CPCTC (corresponding parts of congruent triangles are congruent), we know that AC = DE. Note how 'A' and 'C' are the first and last letters of ABC; similarly, 'E' and 'D' are the first and last letters of EBD. Segment ED is the same as segment DE.

So to find the length of DE, we need to find the length of AC. To do that, we need the value of x.

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

Recall earlier that AB = BE. Use this to find x

AB = BE

1.5x = 3x-6

1.5x-3x = -6

-1.5x = -6

x = -6/(-1.5)

x = 4

Now we can find the length of AC

AC = x+3

AC = 4+3

AC = 7

This must mean DE = 7 as well.

Answer:

DE=7

To do this we need y to be positive and by itself

So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)

Doing this we have

-x+6=y

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15. How fast is it flying? Do not include units

Answers

Answer:

0.15

Step-by-step explanation:

Given the expression that relates the distance and the time with the expression:

d = 0.15t

d is the distance

t is the time

To determine how fast it is flying (Speed), we will need to use the formula

Speed = distance/time

s = d/t

From the given equation we can se that 0.15 = d/t

Comparing this to the general equation, we will see that s = 0.15

Hence the airplane is flying at 0.15

Write the equation of the line that passes through the points (-8,3) and
(3,2). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.

Answers

Answer:

Slope of a line can be found by

y~2 - y~1 / x~2 - x~1

The coordinates given are (-8,3) and (3,2)

2 - 3 / 3 - (-8) = - 1/11 this is your Slope, m

Use the Slope and either point to find b by substituting x and y and m values we know into

y=mx+b

2 = -1/11(3) + b simplify

2 = - 3/11 + b isolate b by adding 3/11 to both sides

22/11 + 3/11 = b = 25/11

Use m and b to write your equation.

y= - 1/11x + 25/11

Mr. Harris has batteries for his calculators. If b represents the number of batteries and c represents his calculators, how many
batteries does Mr. Harris have?
b= 4c
3c = -2b + 44
A 4 batteries
B 7 batteries
13 batteries
16 batteries

Answers

These are simultaneous equations, and you can solve this by using the substitution method:

b = 4c
3c = -2b + 44

3c = -2(4c) + 44
3c = (-2 x 4c) + 44
3c = -8c + 44

11c = 44
c = 44/11
c = 4

b = 4c
b = 4(4)
b = 4 x 4
b = 16

Therefore, Mr. Harris has 16 batteries.

Answer:

35° (Verified Answer) ✅

Step-by-step explanation:

Well, we know that all three angles of a triangle add up to 180°, we set the three equations added together equal to 180°.

180 = x + 10 + 3x - 5 + x

We can simplify this to:

180 = 5x + 5

Now, all we need to do is solve.

Subtract 5.

175 = 5x

Divide by 5

x = 35°

Now, we must check this solution by substituting our solution for x in for x, to see if the values equal.

180 = 35 + 10 + 3 (35)  - 5 + 35

180 = 45 + 3 (35) - 5 + 35

180 = 105 + 45 - 5 + 35

180 = 150 - 5 + 35

180 = 150 + 30

180 = 180 ✅
