How do you solve 7x 56?
Divide both sides by 7. Divide both sides by 7. Divide 56 by 7 to get 8. Divide 56 by 7 to get 8.
What is the value of x in the given equation 7 x minus 7 is equal to minus 14?
To solve this problem, first, isolate x on one side of the equation. x+7-7=14-7 (Subtract 7 from both sides.) 14-7 (Solve and subtract the numbers from left to right.) The correct answer is x=7.
What is the Y intercept of the graph of 7y 56?
Divide y y by 1 1 . Divide 56 56 by 7 7 . Using the slope-intercept form, the y-intercept is 8 .
What is the degree of a linear equation?
In short, the degree of linear equations is always one. For example, 3x + 10 = z, has a degree 1 so it is a linear equation. Linear equations are also called first degree equations, as the exponent on the variable is 1. “Degree” is also called “Order” sometimes.
How do you find X in adjoining figure?
Find x in the adjoining figure:
- To find:-
- Sum of angles forms on a straight line is equal to 180°. This statement is also known as linear pair.
- → y = 90°
- Sum of all interior angles of quadrilateral is 360°.
- → x = 140°
- Verification:-
What is the Y intercept of the graph of?
The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.
What is the answer for 7 * 8?
54
During a Radio Five Live interview in 1998, UK school standards Minister Stephen Byers was asked: What is 7 times 8? He gave the answer 54.
What is the easiest way to simplify 7x?
Simplifying 7x = 56 Solving 7x = 56 Solving for variable ‘x’. Move all terms containing x to the left, all other terms to the right. Divide each side by ‘7’. x = 8 Simplifying x = 8
How do you factor x^2 + 15x + 56?
Add 15x to both sides. Add 1 5 x to both sides. Add 56 to both sides. Add 5 6 to both sides. To solve the equation, factor x^ {2}+15x+56 using formula x^ {2}+\\left (a+bight)x+ab=\\left (x+aight)\\left (x+bight). To find a and b, set up a system to be solved.
How to solve X^ {2}+15x+56 as a function?
Rewrite x^ {2}+15x+56 as \\left (x^ {2}+7xight)+\\left (8x+56ight). Factor out x in the first and 8 in the second group. Factor out common term x+7 by using distributive property. To find equation solutions, solve x+7=0 and x+8=0. Add 15x to both sides.
