y - 5 = 0.5x2 + 6x - 3 How many x-intercepts does this have?
update!!! the answer is 2

Answers

The answer is actually 2 because you have 0.5x (I think that's what it's supposed to be) and 6x.

y = 0.5x^2 + 6x + 2 (adding 5 to both sides of the original equation)

Evaluate 3x + y when x = 1/3 and y = -7/4

Write the answer in simplest form

Answers

Given:
3x + y
Substitute the variables for x = 1/3 and y = -7/4:
3 · 1/3 + -7/4
Multiply 3 by 1/3:
1 + -7/4
Add -7/4 to 1:
-3/4

Final answer:

The expression 3x + y simplifies to -3/4 when x equals 1/3 and y equals -7/4.

Explanation:

To evaluate the expression 3x + y when x = 1/3 and y = -7/4, we simply substitute these values into the expression.

So 3x + y becomes 3*(1/3) - 7/4, which simplifies to 1 - 7/4.

To simplify this further, we convert 1 (which is the same as 4/4) and -7/4 to have the same denominator (which is 4). So, 4/4 - 7/4 equals -3/4.

So, the simplest form of 3x + y when x = 1/3 and y = -7/4 is -3/4.

find an equivalent expression to 3 (4m-2)-2(m+5). write your answer as an expression with two terms

Answers

12m-6-2m+10 (10m+4) is the simplest it can go

Answer:

10m - 16

Step-by-step explanation:

3 (4m-2) -2(m+5)

The equivalent expression can be simplified as an expression with two terms as follows:

3 (4m-2) -2(m+5)

Open each parenthesis by multiplying the outside value with the values in the parenthesis.

3 (4m-2) = 12m - 6

-2(m + 5) = -2m -10

Bring the value together

12m - 6 -2m - 10

collecting like terms

12m -2m - 6 - 10

10m - 16

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?

Answers

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2
So all together is -4×2
A negative times a positive is negative
-4×2= -8
Hope this helped you☺

Final answer:

The football team lost 4 yards on 2 plays in a row, resulting in a change in field position of -8 yards.

Explanation:

The football team lost 4 yards on 2 plays in a row. To determine the change in field position, we need to subtract the total yardage lost from the starting field position. Assuming the starting field position was at the 50-yard line, the change in field position would be -4 yards x 2 plays = -8 yards. Since the team lost yardage, the change in field position would be a negative value.

what does it mean to solve the system of equation?

Answers

Solving a system of equations usually means that you solve for a variable in a specific equation. Systems of equations consist of 2+ equations that contain the same variables.

Ex :

2x + 2y = 8
3x + 3y = 9

Then, using those equations, you solve for x & y

What is 10.49 seconds rounded to the nearest second

Answers

10 seconds... You just have to leave the first two numbers before the point. :) If a number is bigger after the point like for example 10.59 the answer would be 11 because it can be rounded by the 5. :)

Given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

Recall:

When rounding a number, if the number that comes before it is 5, 6 and up to 9, you round the number up. i.e. 57 to the nearest ten would be rounded up to 60.

When rounding a number, if the number that comes before it is from 4 below, you round the number down. i.e. 54 to the nearest ten is 50.

Thus:

Given 10.49 seconds, we want to round the number to the nearest second.

We need to round it down.

Therefore:

10.49 to nearest seconds = 10 secs.

In summary, given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

Dominique used the inequality below to find the maximum number of sweatshirts she could purchase with her savings.

32 x < 300

What is the greatest number of sweatshirts Dominique can purchase?

Answers

We just have to find the closest number that can be multiplied by 32 and still be under 300. Do this by following this step:

Divide by 32 on both sides.

x < 9.375

We can't buy 9.375 sweatshirts though, and we can't add more decimals or it will go over 300, so you round down to 9.

Dominique can buy 9 sweatshirts without going over $300!

Answers

each statue costed 21 dollars

Hello! In order to solve this problem, first, you have to subtract the 72 dollars she didn’t spend on statues from 240. 240 - 72 = 168. That’s $168 she spent on statues. She bought 8 of them. Now, divide the total cost by 8. 168/8 = 21. There. Each statue Ciara bought costed $21.

write a linear equation that is parallel to 12x+3y=24 and passes through the point (-2,7)

Answers

In order to write the formula for another line which is parallel, we need the slope (m). Parallel lines never in fact touch or intersect at any one point. They are either the same lines, occupying the same points, or different parallel lines, never occupying the same points, but sharing the same slope (m).
If we put out equation in slope-intercept format: y = mx+b, we can obtain our needed m.
12x+3y=24 ->> 3y = -12x+24
3y/3 = (-12x+24)/3 ->> y = -4x+8, therefore our m = -4
Now we can use our info to make the line in point-slope format: y-y1 = m (x-x1)
So, y-7 = -4 (x--2) or y-7 = -4 (x+2)
You can leave it like that or convert it:
y-7 = -4x -8 ->> y = -4x -8+7 ->> y = -4x-1
or even in this format: 4x+y=-1
