What is the x-intercept of the equation 7x + 3y = 21?
(0,3)
(0,7)
(3,0)
(7,0)

Answers

Answer:(3,0)

Explanation:To find the x substitute 0 in for y,7x+3*0=21.Next,multiply 3 and 0,and that gives you 0,7x+0=21 .After you do that you need remove 0 because when you add and subtract zero the quantity doesn’t change,7x=21.Lastly,divid both sides of the equation by 7,and that gives you x=3.

Ingrid and Harish were trying to solve the equation:
x^2-3x=x+1
Ingrid said, “First, I'll subtract x from both sides so I have x^2-4x=1. Then I can solve by completing the square. If I add 4 to each side, I can rewrite the equation as (x-2)^2=5. Harish said, “I'll isolate the x^2x term by adding 3x to both sides of the equation. Then I'll solve by taking the square root.”

Can somebody help me with this question plz !

Answers

Answer:

y=4x-3

Step-by-step explanation:

Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.

y=4x+?

Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get

1=4(1)+b

reduce

1=4+b

subtract 4 from both sides

-3=b

and now we can add b=-3 into the original answer, and we get y=4x-3!

Answers

Answer:

a.

Step-by-step explanation:

(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.

Answer:

D. The relation represents y as a function of x, because each value of x is associated with a single value of y

Step-by-step explanation:

As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.
