What is the graph of 3x + 5y = –15?

Answers

Answer 1

Answer:

Answer:

Graph is option A

Step-by-step explanation:

3x + 5y = –15

To graph the equation , we need to get y alone

$3x + 5y = –15$

Subtract 3x on both sides

$5y = -3x–15$

Divide whole equation by 5

$y=-(3x)/(5) -3$

To graph this equation , we need to make a table

Plug in some number for x and find out y

x $y=-(3x)/(5) -3$

0 -3

-5 0

Two points on the graph is (-5,0) and (0,-3)

Graph is option A

The Measure of AXB is 234. what is the measure of ABC in tangent chord angle

Answers

The measure of angle ABC tangent chord angle is 117°.

What is Tangent of a Circle?

Tangent of a circle is defined as the line that passes through exactly one point on the circle.

Chord is the line segment that has it's two end points on the circle.

A chord AB is drawn.

AXB is one of the arc which measures 234°.

We have to find the angle that a tangent through B makes with chord AB.

This measure will be half of the arc measure.

Angle ABC = 234° / 2 = 117°

Hence the measure of the angle ABC is 117°.

Answer:D

Step-by-step explanation:

the bakery bought 4 bags of flour containing 3.5 kg each .475 g flour are needed to make a batch of muffins and 0.65 kg is needed to make a loaf of bread. if 4 batches of muffins and 5 loaves of bread are baked , how much flour will be left ? give your answer in kilograms.

Answers

1 kg = 1000g
1 bag = 3500g
4 bags = 14000g or 14 kg
4 batches of muffins = 1.9g or .0019kg
5 loaves of bread = 3.25kg
.0019 + 3.25 = 3.2519kg
14 - 3.2519 = 10.7481kg
their are 10.7481kg of flour left
