Answer:
The answer SHOULD be 7/8=224/x;256 pounds.
You may have made a mistake in inputting it here on Brainly. So look for the one that matches that.
Step-by-step explanation:
This is what we know:
Jasper = 224 pounds
Balin = x
Jasper = 7/8 of x
Now we make an equation for that:
To match the selections we will isolate 7/8 on one side of the equation:
Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:
So x = 256 pounds
Good job oh my God you are so smart oh my God a good job bro
Answer:
Step-by-step explanation:
There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is
We have the function
From this function, we can find that
We can plug in our know values into the formula to get
Then we can plug in our x-value to find the y-value of the vertex
This means that the vertex would be
<span>This is a quadratic equation . We order to equate to zero
</span>2x²<span> – 7 = 9
</span>
2x² - 7-9 = 0
2x² - 16 = 0
This equation is a binomial
2* (x² - 8) = 0
<span>We choose the simplest method . The equation with practice it can be calculated in the memory
</span><span>
The product is equal to 0 if one of the factors is zero

2≠0 ∨ x² - 8 = 0
x² = √8
x = √8 ∨ x= - √8
Answer : x = √8 ∨ x = -√8
