7x^2-10=-17 solve by taking square root

Answers

Answer 1

The solution to the equation 7x² - 10 = -17 is x = i

How to determine the solution to the equation

From the question, we have the following parameters that can be used in our computation:

7x^2-10=-17

Express the equation properly

So, we have the following representation

7x² - 10 = -17

Add 10 to both sides of the equation

This gives

7x² = -7

Divide both sides by 7

x² = -1

Take the square roots

x = √-1

Rewrite as

x = i

Hence, the solution is x = i

A mooncake with two egg yolks costs $2 more than a mooncake with one egg yolk. The cost of 6 mooncakes with two egg yolks and 5 mooncakes with one egg yolk is $130.80. Find the cost of a mooncake with two two egg yolks.

Plz do in algebraic method

Answers

6(x + 2) + 5(x) = $130.80
6x + 12 + 5x = 130.80
11x = 118.80
x = 10.80, the cost of a moon cake with one egg yolk. Add 2 for the cost of the two egg yolk cake, and your answer is $12.80

6(12.80) + 5(10.80) = 76.80 + 54 = 130.80 ✅

How do I solve this equation?

Answers

Answer:

n=3

Step-by-step explanation:

distribute, then add 3 to both sides, then divide both sides by 3

Answer:

n = 3

Step-by-step explanation:

3(n−1)=6

Step 1: Simplify both sides of the equation.

3(n−1)=6

(3)(n)+(3)(−1)=6(Distribute)

3n+−3=6

3n−3=6

Step 2: Add 3 to both sides.

3n−3+3=6+3

3n=9

Step 3: Divide both sides by 3.

3n/3  = 9/3\

n= 3

the slope is 2

Step-by-step explanation:

to find slope all you need to do is look at the places where the line and the graph intersect. you should be able to find atleast 2 places. Once you have done that, count up how ever many spaces it is until you are on the same line with the place where the line intersects with the graph remember that number in your head, then could left or right until you are on top of the other place where it intersects, remember that number. In this case I counted 2 spaces up and 1 space to the left which gave me 2/1 which is 2

Answers

The unknown value of x from the diagram is 80 degrees.

The given diagram is an isosceles triangle.

The base angle of an isosceles triangle are equal

The sum of angle in a triangle is also 180 degrees. Hence:

x + 50 + 50 = 180

x + 100 = 180

Subtract 100 from both sides

x + 100 - 100 = 180 - 100

x = 80 degrees

Hence the unknown value of x from the diagram is 80 degrees.
