The answer would be A. m= -3/5 and b=-4/5
"m= -5-1 divided by 7--3
or, -6/10
or, -3/5.

to find the (B)

<span><span>(-3,1). y=mx+b or 1=-3/5 × -3+b, or solving for b: b=1-(-3/5)(-3). b=-4/5.</span><span>(7,-5). y=mx+b or -5=-3/5 × 7+b, or solving for b: b=-5-(-3/5)(7). b=-4/5.</span></span>See! In both cases we got the same value for b. And this completes our problem.

The ornament below is composed of two congruent square pyramids. Each square pyramid has base side lengths of 2 inches and a hei
kondor19780726 [428]

Answer:

The volume of the ornament is 6\frac{2}{3}\ in^{3}

Step-by-step explanation:

we know that

The volume of the ornament is equal to the sum of  the volume of the two congruent square pyramids

so

V=2[\frac{1}{3}b^{2} h]

we have

b=2\ in

h=2.5\ in

substitute

V=2[\frac{1}{3}(2)^{2} (2.5)]

V=\frac{20}{3}\ in^{3}

Convert to mixed number

\frac{20}{3}=\frac{18}{3}+\frac{2}{3}=6\frac{2}{3}\ in^{3}

Given: ABC is a right triangle with right angle C. AB = 14 centimeters and
Snezhnost [94]

Answer:7.6°

Step-by-step explanation:

Using sine formular

sinA/a =sinB/b

sin33/x = sin90/14

cross multiply

xsin90 = 14sin33

Divide bothside by sin90

x = 14sin33 / sin90

x= 7.6249 / 1

x = 7.6° to the nearest tenth.

Lina20 [59]

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

15x+57 \geq  129

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

15x\geq  72

Dividing both sides by 15.

x \geq   4.8\

Correct option is A.
