Complete the statement for the equation y=-1/2x-1/2.
Enter the correct answer in the box.
The graph crosses the y-axis at (0,?)
9514 1404 393
Answer:
-1/2
Step-by-step explanation:
The constant in the equation is the value that y has when x=0, because the x-term evaluates to zero when x=0. The constant term in this equation is -1/2, so that is the y-value when x=0.
(x, y) = (0, -1/2) . . . . where the graph crosses the y-axis
-4x+9y=9
x-3y=-6
Solve using Elimination
Answer:
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 1.
4(x−3y=−6)
1(−4x+9y=9)
Becomes:
4x−12y=−24
−4x+9y=9
Add these equations to eliminate x:
−3y=−15
Then solve−3y=−15for y:
−3y=−15 (Divide both sides by -3)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x−3y=−6
Substitute5foryinx−3y=−6:
x−(3)(5)=−6
x−15=−6(Simplify both sides of the equation)
x−15+15=−6+15(Add 15 to both sides)
x=9

7TH GRADE MATH IF YOU HELP ILL GIVE BRANLIEST AND 10 POINT//PROBABILITY
Answer:
1. 1 in 5
2. There are 5 colors it could land on, and orange is one of them.
3. 40 different combinations
4. There are 5 colors with 8 corresponding numbers. 5x8=40
Step-by-step explanation:
1) 20%
2) Assuming that on the spinner with color, every section has an equal share, then the probability of landing on orange is [tex]\frac{1}{5}[/tex] or 20%. This is because, the orange section is one of the five equal sections, or [tex]\frac{1}{5}[/tex] or the spinner. [tex]\frac{1}{5}[/tex] in decimal form is 0.2, to convert to a percent, multiply by 100. Hence one gets, 20%.
3) 40
4) There are 5 sections on the spinner with color, hence 5 possible outcomes when one spins the spinner. On the black and white spinner, there are 8 sections, hence 8 possible outcomes when one spins the spinner. To find the total number of outcomes resulting from the two events, one must multiply the total outcomes from one event by the total outcome of the other event. When one does this, they get that there are 40 possible events.
Grandma's Recipe for Sugar Cookies
1 cups kutter
2 cups sugar
4 eggs
12 teaspoon baking powder
1% cups flour
4 teaspoon salt
Your sister wants to make more cookies and decides to use 4 cups of sugar. She says that she
will need to use 3 1/4 cups of flour. Do you agree with her? Explain your reasoning.
Answer:
I agree
Step-by-step explanation:
The sugar sweetens the cookies and also because it's a sugar cookie the sugar content should be a little bit more. And when the flour is too much it makes the cookie bumpy because of its dry content. The sugar should be more to give the cookie its expected taste

Answer:
(1, 3)
(2, 6)
(4, 12)
(6, 18)
Step-by-step explanation:
Time represents s, or the x value when plotting (x, y) and distance represent m or the y value when plotting.
For the first one, plot it at (1, 3), so look where time is, the horizontal line, and find one. Then from there, go up three places. That is where you will plot your first point.
The second one will be plotted at (2, 6). Find two on the horizontal line, and then go up six spaces. That is where you will plot your second.
Do the same thing for the last two. You should plot your points at:
(1, 3)

(6, 18)

A box has length 7 feet width 4 feet and height 5 inches find the volume of the box in cubic feet and in cubic inches
Answer:
20160in3
Step-by-step explanation:
1.) Convert all measurements to inches
7ft = 84in
4ft = 48in
5in = 5in
2.) Multiply all of the values to find the volume
84in x 48in x 5in = 20160in3

Find slope. plzz help me
Hello!
[tex]\large\boxed{slope = 2}[/tex]
Find the slope using the slope formula:
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
We can use two points from the table and plug these into the equation. Use the points (5, 10) and (10, 20) to solve:
[tex]slope = \frac{20 - 10}{10 - 5}[/tex]
Simplify:
[tex]slope = \frac{10}{5}[/tex]
[tex]slope = 2[/tex]

D.X4
Answer:
Step-by-step explanation:
D
The graph represents the inequality y < 1.
Option B is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
The horizontal line through the point (4, 1).
This horizontal line passes through y = 1.
The region below this horizontal line will be y < 1.
Thus,
The graph represents y < 1.

Javier teaches yoga classes at his community center. In a 60-minute class last night, he taught 30 poses. Today, he has a 30-minute class.
If he teaches at the same rate, how many poses will Javier teach in today's class?
Answer:
I'm guessing 15 poses because 30/60 half and 15/30 half so basically in the 60 minute lesson Javier spend 1 minute teaching them how do to each pose, so in the 30 minute lesson he'll spend 1 minute on the other poses.

3/4 + 3/8 how do I do this I messed the last one up
Answer:
1 1/8

We need to add the fractions; 3/4 and 3/8
Step 1, get the LCM of 4 and 8. The LCM of 4 and 8 is 8
Step 2, 3/4 + 3/8 = 6 + 3/8 = 9/8 = 1 1/8
Hence, 3/4 + 3/8 = 1 1/8
