Which ordered pair is a solution to the following:
Y= -2x + 5
Choose 1 answer:
A: Only (2,-9)
B: Only (-2,9)
C: both
D: neither
Answers
Answer:
Option B: Only (-2, 9)
Step-by-step explanation:
Given the linear equation, y = -2x + 5:
We'll plug in the given options to see which of the ordered pairs will satisfy the equation:
Substitute option A: (2, -9) into the equation:
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1 (False statement). Therefore, (2, -9) is not a solution.
Substitute option B: (-2, 9) into the equation:
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9 (True statement). Therefore, the ordered pair, (-2, 9) is a solution.
The other two options are irrelevant at this point since we've proven that option B is the correct answer.

No, 5x+y^2=25 is not a linear equation.
What is termed as the linear equation?A linear equation is one in which the variable's highest power is always 1. A one-degree equation is another name for it. A linear model in one variable has the standard form Ax + B = 0. In this equation, x is a variable, A is a coefficient, and B is constant. A linear equation throughout two variables has the standard form Ax + By = C.For the given equation;
5x+y^2=25
the highest power of the equation is 2.
Thus, the given equation is a quadratic equation or 2 degree equation.
Therefore, the given equation is not a linear equation.

3x+10=43 what is x to the what are the steps to equal X to the math equation
Answers
Answer:
x = 11
Step-by-step explanation:
When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:
3x = 33
Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!

You can find the third angle of the bottom triangle by 180 - 43 - 35 = 102
The vertical angle above it is also 102.
Then, to find the measure of angle A, you do 180 - 102 - 18 = 60
So, the measure of angle A is 60 degrees.
Answer:
60°Step-by-step explanation:
Since Angle E is same for both triangles, as vertical angles, the sum of the other two interior angles should be same.
Then we have:
m∠A + m∠B = mC + m∠Dm∠A + 18 = 43 + 35m∠A + 18 = 78m∠A = 78 - 18m∠A = 60What is the smallest integer 160 needs to be multiplied by to give a square number

Camille's science class is making slime from cornstarch and glue. Camille is helping pass out materials. She gives each student 4 ounces of cornstarch from a 5-pound bucket. If Camille's class has a total of 18 students, how many ounces of cornstarch will she have left?
Answers
Answer:
8 ounces
Step-by-step explanation:
16oz/lb
16*5= 80oz of cornstarch in bucket
4oz * 18students = 72oz
80-72= 8 oz remaining
The amount of cornstarch left is 8 ounce.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Each student get = 4 ounce of cornstarch
Total number of student = 18 students
And, Total amount of cornstarch = 5 pound
Here,
Since, Amount of total cornstarch to student = Each student get × Total number of student
⇒ Amount of total cornstarch to student = 4 × 18
⇒ Amount of total cornstarch to student = 72 ounce
Since, 1 pound = 16 ounces
So, We get;
⇒ Total amount of cornstarch = 5 × 16
⇒ Total amount of cornstarch = 80 ounces
Thus, Amount of cornstarch left = 80 - 72
⇒ Amount of cornstarch left = 8 ounces

Step-by-step explanation:
1 cup of mango and 3 cups of strawberries. And 2 cups of mango and 6 cups of strawberries are they equivalent
Answers
Answer:
Yes
Step-by-step explanation:
First off, let's use an example with the same equivalence:
[tex]\frac{12}{36} =\frac{16}{48}[/tex]
If you divide the denominator by the numerator you have to get 3, otherwise, it's not equivalent.
The constant of proportionality between the denominator and the numerator, if we use x and y, is:
[tex]y=3x[/tex]
So, just like the example and explanation I used, 3 divided 1 is 3 and 6 divided by 2 is 3.
Answer:
Yes, the 2 cups of mango and 6 cups of strawberries are equivalent.
Step-by-step explanation:
The question is based on ratios. Ratios are basically the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. In this instance, you're altering the quantity by 2. So the 1 cup of mangoes becomes 2 cups of mangoes and the 3 cups of strawberries becomes 6 cups.
Another example of this could be:
In the store, for every 1 man there are 4 women. So if you change the amount of men in the store from 1 to 2, the quantity of women would go from 4 to 8.
