The linear equation 2x + 5y = 7 has infinitely many solutions.
In this question we need to determine the number of solutions of the linear equation 2x + 5y = 7.
We know that an equation of the form ax + by + c = 0, where a, b and c are real numbers such that a ≠ 0 and b ≠ 0, is called as a linear equation in two variables.
Also as we know a linear equation in two variables has infinitely many solutions. The graph of linear equation in two variables is a straight line. Every point on the straight line represents a solution of the linear equation.
Here we have a linear equation in two variables 2x + 5y = 7.
By rearranging given linear equation we get,
5y = 2x - 7
y = (2x - 7)/5
Here we will get different values of y for different values of x
Therefore, the linear equation has infinitely many solutions.

Which is a solution of 2x(8x + 5) (7x – 13) = 0?
Answer:
Step-by-step explanation:
This has 3 solutions
2x = 0 Divide by 2
x = 0
8x + 5 = 0 Subtract 5 from both sides
8x = - 5 Divide by 8
x = - 5/8
x = -0.625
7x - 13 = 0 Add 13 to both sides
7x = 13 Divide by 7
x = 13/7
x = 1.86
A ladder leans against the side of a house the top ladder is 16 ft from the ground the bottom of the ladder is 12 ft from the side of the house find the length of the ladder if necessary round your answer to the nearest tenth
Answer:
[tex] {h =}^{2} = {p}^{2} \: + {b}^{2} [/tex]
[tex] {h}^{2} = {16}^{2} + {12}^{2} [/tex]
[tex] {h}^{2} = 256 + 144[/tex]
[tex]h = \sqrt{400} [/tex]
[tex]h = 20[/tex]
therefore the length of the ladder is 20ft

Rachel makes spirit bows for game day. She uses 48 feet of ribbon for 12 bows. If she uses the same amount of ribbon for each bow, how much ribbon would she need for 10 bows?
Answer:
40 ribbon
Step-by-step explanation:
We need to idenify the ratio which is 1 bow to 4 ribbons, so we times that by ten and we get 10:40 so its 40 ribbons. (Hope it helps)
The amount of ribbon she needs for 10 bows will be 40 feet.
What will be the quantity of ribbons for 10 rows?It is given that
As she uses 48 feet of ribbon for 12 bows.
So for one bow, the ribbon will be
[tex]\dfrac{48}{12} =4[/tex]
So now if the size of the ribbon should be the same for the new 10 bows then
Size =[tex]10\times 4=40\ feet[/tex]
Thus the amount of ribbon she needs for 10 bows will be 40 feet

At a football game, 65% of people attending were supporting the home team, while 35% were supporting the visiting team. If 1300 people attending the game supported the home team, what was the total number of people attending the game? HELP ME I NEED AN A IN MATH!
Answer: 2000
Step-by-step explanation:
Percentage supporting home team = 65%
Percentage supporting visiting team = 35%
Number of people supporting home team = 1300
Let the total number of people attending the game be represented by x.
Therefore, 65% of x = 1300
65/100 × x = 1300
0.65 × x = 1300
0.65x = 1300
x = 1300 / 0.65
x = 2000
Therefore 2000 people attended the game.
A cone has a volume of 565.2 cubic millimeters and a radius of 6 millimeters. What is its
height?
Use I 3.14 and round your answer to the nearest hundredth.
Answer:
h = 15 mm
Step-by-step explanation:
Given that,
The volume of a cone, V = 565.2 cubic millimeters
The radius of the cone, r = 6 mm
We need to find its height. The formula for the volume of the cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
Where
h is the height of the cone
[tex]h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 565.2 }{3.14 \times 6^2}\\\\h=15\ mm[/tex]
So, the height of the cone is equal to 15 mm.

Help me with #6 Please
Answer:
4 - pi
Step-by-step explanation:
we see that the inner square leg is 2 inch because its radius + radius
which is 1+1 (two circles diameters are 4 inches, so one circle has 1 inch radius) square area = 4 inches.
we subtract the area of 4 circle quadrants which is a circle area.
area of the circle is pi r^2, r = 1 so A = pi inch
the shaded region is (4 - pi) inch squared.
For which of the following equations is (-3,-2) not a solution?
Answer:
-5
Step-by-step explanation:
Just add the numbers and if they both got negative numbers it is negative
No equation in the answer choices has a solution pair of (-3,-2) as as evident from the computation below.
Solution pair for EquationsTo determine which equations are not satisfied by the solution pair; (-3,-2), we must substitute the solution pair into each equation as follows;
−3x=4y−6; -3(-3) = 4(-2) - 6; 9 = -14; Falsey=x−1; -2 = -3 -1; -2 = -4; False5x+2y=−16; 5(-3) + 2(-2) = -16; -19 = -16; False2(-2) - 3(-3) = 0; +5 = 0; FalseIt follows form the computation above that, the solution pair is not a solution to any of the equation choices.
Remarks:
Select one: a. −3x=4y−6 b. y=x−1 c. 5x+2y=−16 d. 2y−3x=0
