Answer:
8
Step-by-step explanation:
3(2)-2(1-2) / 3-2
6+2 / 1
8/1
= 8
Answer:
A= Q/d +N
Step-by-step explanation:
First you want to move the d term over by dividing both sides
Next you can move the N over by adding it to both sides.
Hey there! Welcome to Brainly! I'm happy to help you!
Let's quickly write our equation below.
4(1-x)+2x=-3(x+1)
To solve this, we want to get the x by itself on one side of the equation so we can see what it equals on the other side. First, we need to get it out of the parentheses. To do this, we will use the <em><u>distributive property </u></em>and multiply the number before the parentheses by both terms inside of it as seen below! :)
4(1)-4(x)+2x=-3(x)-3(1)
4-4x+2x=-3x-3
Now, we need to combine our like terms.
4-2x=-3x-3
Now, we want to get all of our constants (numbers without variables) onto the right side. First, we will subtract four from both sides.
-2x=-3x-7
Now, we will add 3x to both sides.
x= -7
I hope that this helps! Have a wonderful day!
Answer:
x^2 + y^2 = 25
Step-by-step explanation:
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:
x^2 + y^2 = 25
Answer:
The answer is given below
Step-by-step explanation:
The equation of a quadratic function is given by:
Ax² + Bx + C where A, B and C are the coefficients of the quadratic equation. If the coefficient of x² (i.e A) is a negative value then the graph opens down, the value of C determines the y intercept.
The equation of a parabola with y-intercept greater than 3 and opens down can be given as -2x² -6x + 4. Since the coefficient of x² is negative it opens down and C = 4, it has a y intercept of 4 > 3
Let us assume a vertical stretch of 2, the new equation becomes:
2(-2x² -6x + 4)
-4x² - 12x + 8
To solve:
-4x² - 12x + 8 = 0
A = -4, B = -12 and C = 8
Using the quadratic formula:
