Determine the coordinate of the point where
2x+y=5 crosses the x-axis.
Answer:
(2.5, 0)
Step-by-step explanation:
The point in which a line crosses the x-axis is also known as the x- intercept. x-intercepts occur at y= 0, so let's substitute y= 0 into the equation and solve for x.
2x +y= 5
When y= 0,
2x +0= 5
2x= 5
Divide both sides by 2:
x= 2.5
Thus, the coordinate is (2.5, 0).

Solve the system of equations:
y= 2x - 2
y= x2 - x-6
O A. (-1,-5) and (4,2)
O B. (0, -2) and (2, 2)
O C. (-1,-4) and (4, 6)
D. (-2,0) and (3,0)
Answer:
C) (-1, -4) and (4, 6)
Step-by-step explanation:
[tex]\textsf{Equation 1}:y=2x-2[/tex]
[tex]\textsf{Equation 2}:y=x^2-x-6[/tex]
Substitute Equation 1 into Equation 2 and solve for x:
[tex]\implies 2x-2=x^2-x-6[/tex]
[tex]\implies x^2-3x-4=0[/tex]
Find two numbers that multiply to -4 and sum to -3: -4 and 1
Rewrite the middle term as the sum of these two numbers:
[tex]\implies x^2-4x+x-4=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies x(x-4)+1(x-4)=0[/tex]
Factor out the common term [tex](x-4)[/tex]:
[tex]\implies (x+1)(x-4)=0[/tex]
[tex]\implies (x+1)=0 \implies x=-1[/tex]
[tex]\implies (x-4)=0 \implies x=4[/tex]
Substitute the found values of x into Equation 1 and solve for y:
[tex]x=-1 \implies y=2(-1)-2=-4[/tex]
[tex]x=4 \implies y=2(4)-2=6[/tex]
Therefore, the solution to the system of equations is:
(-1, -4) and (4, 6)
The coordinates of a quadrilateral are (1,3), (7,-3), (1,-9), and (-5,-3). What shape is formed? Select all that apply. -Kite -Rectangle -Rhombus -Square -Trapezoid
Answer: Sqaure
Step-by-step explanation:
We obtain the figure by either plotting or finding the distances between the points:
[tex]\begin{aligned}&\text { Distance } b / w \quad A B =\sqrt{(1-7)^{2}+(3-(-3))^{2}}\\&=\sqrt{6^{2}+6^{2}}\\&A B=\sqrt{72} \text { units }\end{aligned}[/tex]
[tex]\text { Distance } b / w \quad BC =\sqrt{(7-1)^{2}+(-3-(-9))^{2}} \\BC=\sqrt{72} \text { units }[/tex]
[tex]\begin{aligned}\text { Distance } b / w \ C D &=\sqrt{(1-(-5))^{2}+(-9-(-3))^{2}} \\C D=\sqrt{72} \text { units }\end{aligned}[/tex]
[tex]$$ Distance $b/w \ A D=\sqrt{(1-(-5))^{2}+(3(-3))^{2}}$A D=\sqrt{72} \text { units }[/tex]
Since all the distances of the four sides are equal, we have to check if the shape is either a rhombus or a square by the measuring the length of the diagonals
[tex]\begin{aligned}A C &=\sqrt{(1-1)^{2}+(3-(-9))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units } \\B D &=\sqrt{(7-(-5))^{2}+(-3-(-3))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units }\end{aligned}[/tex]
The diagonals are also equal; therefore, the figure is a square

The first bricklayer can build a wall in 15 days, and the second bricklayer can build the same wall in 10 days How long will it take for them to build the wall together?
Answer:
It will take both of the brick layers twelve and half days
6 Days
Step-by-step explanation:
First you must find the combined rate of work per day between the two bricklayers.
(100/10)+(100/15) = 16 2/3
For each day the two bricklayers complete 16 2/3 percent of the work. To find out the amount of days it take them to build the wall you divide 16 2/3 from 100
100/16 2/3 = 6
The amount of days it take the two bricklayers to build the wall together is 6.

Answer:
Degree: cubic
Number of terms: binomial
Step-by-step explanation:
Look at the exponents to find the degree. Biggest exponent is 3, third power, that's a cubic, like a cube.. 3D.
There's a plus separating the two terms...Two terms-that's the "bi-" in binomial, like a bicycle or bifocals or binational. The prefix "bi-" means two.

Which statement is not true about the data shown by the box plot below?

A. The median of the data is 55.
B. The interquartile range is 55.
C. Three fourths of the data is less than 65.
D. The median of the upper half of the data is 65.
Reset Selection
Answer:
B. The interquartile range is 55
Step-by-step explanation:
the interquartile range is Q3 minus Q1, you would get 15 ,not 55. So B is the answer to your question
Answer:
B. The interquartile range is 55.
Step-by-step explanation:
In this problem, I refer to the right part of the box as the median of the upper half and the left part of the box as the median of the lower half.
The median of the data is going to be the middle line of the box and whisker plot. The middle line lies on 55, so the median is 55.
Choice A is true
The interquartile range is the right end of the box subtracted from the left end of the box. The right end of the box is 65. The left end of the box is 40. Subtracting the left end from the right end, we get 25.
Choice B is false
3/4 of the data will be where we see the right end of the box. The right end of the box is at 65. So, 3/4 of the data is less than 65.
Note: 1/4 of the data is less than the left side of the box at 40. 1/2 of the data is less than the median of the box which is at 55.
Choice C is true
The median of the upper half is the right end which is 65.
Note: The median of the lower half is 40.
Choice D is true
