Use the Pythagorean theorem (a^2 + b^2 = c^2)

7^2 + 24^2 = x^2

x^2 = 625

x = 25

On the grid draw the graph of x + 2y =7

Elena-2011 [213]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$x + 2y = 7$

Required

Draw the graph

First, we identify at least 2 possible values of x and y

Let $x = 1$

Solve for y

$x + 2y = 7$

$1 + 2y = 7$

$2y = 6$

$y = 3$

So, a point is: $(1,3)$

Let $x = 3$

Solve for y

$x + 2y = 7$

$3 + 2y = 7$

$2y = 7 -3$

$2y = 4$

$y = 2$

So, another point is: $(3,2)$

Plot $(1,3)$  and  $(3,2)$  on the graph, then draw a straight line through both points

Circumstance of 12yd

marusya05 [52]

Answer: 40.82yd

Step-by-step explanation:

First of all, it's ''circumference'' and second of all, it's ''13yd''.

$Formula: C=2\pi r$

2r is the same as d = diameter,

$C=\pi d$

$C=(3.14)(13)\\C=40.82yd$

Alex Ar [27]

Answer:

$\large\boxed{x=3,\ y=0\to(3,\ 0)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}2x+3y=6&(1)\\x=-2y+3&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\2(-2y+3)+3y=6\qquad\text{use distributive property}\\\\(2)(-2y)+(2)(3)+3y=6\\\\-4y+6+3y=6\qquad\text{subtract 6 from both sides}\\\\-y=0\to\boxed{y=0}\\\\\text{Put the value of y to (2):}\\\\x=-2(0)+3\\\\x=0+3\\\\\boxed{x=3}$
