What type of equations could have extraneous solutions?
Answer:
id
Step-by-step explanation:
The square root equations could have extraneous solutions.
What is an extraneous solution?An extraneous solution is a “false” solution to an equation. An extraneous solution does not satisfy the original equation, even though we took seemingly valid steps while solving the equation.
When we solve an equation with containing a radical expression, we have to isolate the radical on one side from all other terms and then square both sides of the equation.
When we square a radical equation we sometimes get a solution to the squared equation that is not a solution to the original equation. Such an equation is called an extraneous solution.
Hence, the square root equations could have extraneous solutions.

7 1/2 is equal to _____ in radical form?
Answer:
√ 7
.........................
7 1/2 in radical form is √15 / √2 x √15 / √2.
To convert the mixed number 7 1/2 to radical form, we need to rewrite it as an improper fraction and then simplify.
First, let's convert the mixed number to an improper fraction:
7 1/2 = (2 x 7 + 1)/2 = 15/2
Next, we can represent 15/2 in radical form by taking the square root of the numerator and the denominator separately:
√(15/2)² = √15 / √2 x √15 / √2
The square root of 15 cannot be simplified further, so we leave it as √15.
Therefore, 7 1/2 in radical form is √15 / √2 x √15 / √2.

Jose has six pieces of cardboard to make a triangle frame for a diorama. The lengths are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches. Which combination will form a triangle?
The possible combination of sides of triangles is
(2 + 3) >4(3 + 4)> 5(5+ 6)>7What is Property of Triangle?In a triangle, the third side must be greater than or equal to the sum of the other two sides. The length of a triangle's third side is always longer than the sum of any two of its sides.
Given sides are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches.
We know that the third side of a triangle is greater than sum of other two sides.
So, (2 + 3) >4
and, (3 + 4)> 5
and, (5+ 6)>7

ABC congruent DEF find the measure of the given angles or the lengths of the given sides
Answer:
BC = 8 and EF = 8
Step-by-step explanation:
Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.
Let us solve the question
∵ The two triangles ABC and DEF are congruent
∴ BC = EF
∵ BC = 3z + 2
∵ EF = z + 6
→ Equate their length
∴ 3z + 2 = z + 6
→ Subtract z from both sides
∵ 3z - z + 2 = z - z + 6
∴ 2z + 2 = 6
→ Subtract 2 from both sides
∵ 2z + 2 - 2 = 6 - 2
∴ 2z = 4
→ Divide both sides by 2
∴ z = 2
→ Substitute z by 2 in the length of sides BC and EF to find them
∵ BC = 3(2) + 2 = 6 + 2
∴ BC = 8
∵ EF = 2 + 6
∴ EF = 8

Select the best answer from the choices provided.
A.
trapezoid
B.
parallelogram
C.
rhombus
D.
concave quadrilateral
9514 1404 393
Answer:
A. trapezoid
Step-by-step explanation:
The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.
The figure has one pair of parallel sides, so is a trapezoid.

Solving two-step inequalities is much like solving two-step equations. Use
inverse operations to
solve each of the following inequalities.
5x + 8.5 > - 10.3
2x - 10 < 80
Answer:
1) x>-3.76 2) x<45
Step-by-step explanation:
1) 5x+8.5>-10.3
Isolate the variable
Combine like terms/ subtract 8.5 from both sides
5x>-18.8
Divide by sides by 5
x>-3.76Remember, if we were dividing or multiplying by a negative number, we would switch the inequality sign, but here we do not.
2) 2x-10<80
Isolate the variable
Combine like terms/ add 10 to both sides
2x<90
Divide both sides by 2

The leadership class starts a campaign to change the school mascot. The school principal has agreed to change the mascot if two-thirds of the student body plus 1 additional student vote for the change. The required number of votes is 255. How many students attend the school? (Please also write the equation)
Answer:
254/2=127
127*3=381
381+1=382
Step-by-step explanation:
254/2 because 2/3 of the students is 254 and this is to simplify it
127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them
381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in
The Answer Is: 382
Equation: (254/2)*3+1
Which graph has an x-intercept of -2 and a y-intercept of 4?
Answer:
The first graph
Step-by-step explanation:
the first graph crosses through -2 on the x-axis and 4 on the y-axis
The required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
X intercept is the value of the line where y ordinate is zero, from observation it is found that graph A has x intercept of -2 and y-intercept of 4.
Thus, the required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.
