What is the solution set for −4x − 10 ≤ 2
Answer:
x≥−3
Step-by-step explanation:
−4x−10≤2
Add 10 to both sides.
−4x≤2+10
Add 2 and 10 to get 12.
−4x≤12
Divide both sides by −4. Since −4 is negative, the inequality direction is changed.
x≥12/-4
Divide 12 by −4 to get −3.
x≥−3

Is y=x^2+7 a linear equation?
Answer:
No, it is not a linear equation
Step-by-step explanation:
This equation contains the term x², meaning that it is a quadratic function (parabola)
So, it is not a linear equation.
If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.
The answer is no, it is not a linear equation.
Answer:
Given :-[tex] \large \sf \bullet \: y = {x}^{2} + 7[/tex]
To Find :-Is it a linear Equation
Solution :-We may notice that
x has power as 2.
So,
We know that
A linear Equation doesn't consist of power. Linear equation only consist of variable and constant.
No,
Its a Quardtic equation
How to get the answer for y=2x+3,4x-3y=1 substitution method
Answer:
x=−5 and y=−7
Step-by-step explanation:
Step: Solve y=2x+3for y:
y=2x+3
Step: Substitute2x+3foryin4x−3y=1:
4x−3y=1
4x−3(2x+3)=1
−2x−9=1(Simplify both sides of the equation)
−2x−9+9=1+9(Add 9 to both sides)
−2x=10
−2x
−2
=
10
−2
(Divide both sides by -2)
x=−5
Step: Substitute−5forxiny=2x+3:
y=2x+3
y=(2)(−5)+3
y=−7(Simplify both sides of the equation)

How to get y and z please help I really need this
Answer:
y = 102, z = 70
Step-by-step explanation:
z and 110 are adjacent angles and supplementary, sum to 180° , so
z = 180 - 110 = 70
The sum of the interior angles of a quadrilateral = 360°
sum the given angles and equate to 360
99 + 89 + 70 + y = 360, that is
258 + y = 360 ( subtract 258 from both sides )
y = 102

Joe needs to buy snacks for the chess club. There are 12 people in the club and he wants each person to receive 0.5 pounds (lbs) of grapes. How many pounds of grapes should he buy?
Answer: 6 pounds of grapes
Step-by-step explanation:
There are 12 people that Joe is meant to buy for.
Each of them will receive 0.5 pounds of grapes.
All of them will therefore need:
= pounds of grapes per person * number of people
= 0.5 * 12
= 6 pounds of grapes

Last homework for mathematics, mr Thompson!
Answers:
Have a common difference Have a common factor Have a linear first difference============================================================
Explanation:
Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.
------------------
Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.
------------------
Quadratic functions are a bit strange.
Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....
Let's subtract the adjacent terms (larger - smaller)
4-1 = 39-4 = 516-9 = 725-16 = 9Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.
------------------
For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.
perfect square trinomial conditions
Step-by-step explanation:
step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!
Solve for X y and z brainliest
Answer:
Step-by-step explanation:
"y" is geometric mean
y² = 13 × 2
y = √26 ≈ 5.1
x² = 26 + 4 = 30
x = √30 ≈ 5.5
z² = 15² - 30 = 195
z = √195 ≈ 14.0
