Answer:
Step-by-step explanation:
To find the y-intercept of a graph, we can simply set the value of 'x' equal to 0. If we substitute this into the equation y= x²+3/10, we get:
y= 0²+3/10
y=3/10.
Answer:
B. 172.5 yd squared
Step-by-step explanation:
FIrst, we must find half of the height, which is 15/2 or 7.5.
Next we have to multiply 7.5 times (15+8) which is B.
Answer:
We took $ 24 to the movies.
Step-by-step explanation:
Let total money be
On movies = Half of the money =
On popcorn = 
on candy = $2
On soda = $3
total money spent = ++ 2+3+1
x = ++ 2+3+1
x- - = 6
- - =6
1) add.
for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3
2) subtract
for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3
3) change
for example 3 - (- 2) = 3 + 2
4) -10
the sum is -10.25, which is closest to -10
So, you have 3/4x + 5/8 = 4x. We can do this in two ways. Since fractions are harder to deal with, we can turn the fractions into whole numbers.
First we need to find the LCD (Least Common Denominator) between 4 and 8, which is 8. So multiply the 3/4x by 2/2, which gives you an equivalent fraction of 6/8x.
So now we have 6/8x + 5/8 = 4x. Now multiply both sides by 8, to get rid of the denominators of the fractions. That gives us 6x + 5 = 32x. Now use the subtraction property of equality to subtract 6x from both sides giving us 5 = 26x.
Now you can use the division property of equality to divide 26 on both sides, which gives us x = 5/26.
Hope this helps. :D Feel free to ask any other questions, and if you have any questions about my explanation, don't hesitate to ask.
