Answer:
x = -8 and y= 8
(-8,8) is the answer
Answer:
(2,4) (-4,16)
Step-by-step explanation:
Subtract 2 x from both sides of the equation.
y = 8 − 2 x
Substitute 8 − 2 x for y into x ^2 − y = 0 then solve for x .
x = 2 , − 4
Substitute 2 for x into x 2 − y = 0 then solve for y .
y=4
Substitute − 4 for x into x 2 − y = 0 then solve for y .
y=16
Equation form
x = 2 , y = 4
x = − 4 , y = 16
Which statement is false? A All whole numbers are integers. B All integers greater than 0 are whole numbers. C No real numbers are irrational numbers. D No integers are irrational numbers.
It is false that C. No real numbers are irrational numbers
Real numbers include both irrational and rational numbers so it is not true that a real number cannot be a rational number.
The other options are wrong because:
All whole numbers are indeed integers because integers are numbers that do not have to be written as fractions which makes them whole. All integers greater than 0 are whole numbers because they do not need to be written as fractions. Because integers are whole numbers, they cannot be irrational numbers which are numbers that go on forever e.g. π. Integers are whole which means that they can be completed.Conclusively speaking therefore, the only false statement here is that no real numbers are irrational numbers.

Answer:
Width also known as (W) = 1.5 meters
Area also known as (A) = 6 square meters
Length also known as (L) = ?
the formula to find Length is:
Step-by-step explanation:
[tex]L=\frac{A}{W}[/tex]
[tex]L = \frac{6}{1.5}[/tex]
[tex]L= 4 m[/tex]
Choice 3 is the answer
1.5x = 6
x=4
substitute 4 for the x
1.5(4)=6
1.5×4 = 6
so
6=6
so the answer is
1.5x=6
x=4
The answer would be 4.
If you multiply 1.5 by 4 you get 6.0 and it's the same to 6.

Whats 30 times 30 plus 45 minus 456
Answer:
489 or -113
Step-by-step explanation:
Whats 30 times 30 plus 45 minus 456
rewrite in terms of numbers:
30 * 30 + 45 - 456
remember the order of operations and solve:
30 * 30 + 45 - 456
=900 + 45 -456
= 945 - 456
= 489
the answer could change depending on the placement of parenthesis, such as if the equation was:
30 * (30 + 45 -456)
solve with the order of operations:
30 * ( 30 + 45 - 456)
= 30 * (75 - 456)
= 30 *(-381)
= -11430

Explain how to convert 2.7 × 104 from scientific notation to standard form, then give the answer in standard form.
The exponent positive 4 means we move the decimal four spaces to the right.
The 2.7 becomes 27,000 after doing so
[tex]2.7 \times 10^4 = 27,000[/tex]
If the exponent was negative, then we would move the decimal point to the left.
How do the angle measures and side lengths compare in similar figures ?
Answer:
Matching sides of two or more polygons are called corresponding sides, and matching angles are called corresponding angles. If two figures are similar, then the measures of the corresponding angles are equal and the ratios of the lengths of the corresponding sides are proportional.
Step-by-step explanation:
The angles are congruent in a similar figure and the ratio of the sides is in proportion.
What are similar figures?Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given: Two figures are similar for example say two triangles are similar then Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. We denote the similarity of triangles here by ‘~’ symbol.
Hence, The angles are congruent in a similar figure and the ratio of the sides is in proportion.

Which values are in the solution set of the inequality -9/4x+12≥-8? Select all that apply. A. 6 B. 7 C. 8 D. 10 E. 11
Answer: A, B, C
Step-by-step explanation:
To solve for the inequality, we would solve it as if it had an equals sign.
[tex]-\frac{9}{4} x+12\geq -8[/tex] [subtract both sides by 12]
[tex]-\frac{9}{4} x\geq -20[/tex] [multiply both sides by -4/9, remember to flip inequality]
[tex]x\leq \frac{80}{9}[/tex]
Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.
Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.
