1. Draw!
2. Use trigonometric ratios to solve for the height (Remember SOH CAH TOA)
Hello!!
Well, the x-intercept is found when y = 0, so plug in y = 0:
-7x + 3(0) = 21
-7x = 21
x = -3
Therefore, the x-intercept of -7x + 3y = 21 is -3.
Hope this helps!! Let me know if you have ANY questions.
answer:
gradient is 4
Step-by-step explanation:
gradient is another way of saying slope
slope in the math is often used to show the speed of something
it's the m in y= mx+b
make the equation look like
y = mx + b
2y - 8x = -2
2y = 8x - 2
y= (8x-2)/2
y=4x-1
gradient is the number next to x
answer : gradient is 4
1. A quadratic equation has the following form: ax²+bx+c.
2. The leading coefficient is the number that is attached to the variable with the highest exponent. Then, the "a" is the leading coefficient of the quadratic equation.
3. The problem says that the leading coefficient is 1 (a=1) and the roots of the quadratic equation are 5 and -3. Then, you have:
(x-5)(x+3)=0
4. When you apply the distributive property, you obtain:
x²+3x-5x-15=0
x²-2x-15=0
5. Therefore, the answer is:
x²-2x-15=0
