Answer:

x=7

Step-by-step explanation:

-15-x=-22

1) Add 15 to both sides

-x=-7

2) Divide by negative 1 because x cannot be left as a negative.

Need help with this. Write an equation that is parallel to the line whose equation is y = −8x − 7?

shutvik [7]

Answer:

Problem 4: y = -8x+b

Problem 5: C: 3x-2

Step-by-step explanation:

Problem 4:

The given line is in slope intercept form.

The slope-intercept form is:

$y = mx+b$

Here the co-efficient of x is the slope of the line. Comparing the given equation with general form

m = -8

Two parallel lines have same slope so the slope of line will be -8.

$y=mx+b\\y = -8x+b$

b can be any positive or negative integer as we don't know any point on the line parallel to given line.

Problem 5:

Slope = 3

y-intercept = -2

Slope intercept of line is given by:

$y = mx+b$

here m is slope and b is y-intercept

Putting the values

$y = 3x-2$

Option C: y=3x-2 is the correct answer

Hence,

Problem 4: y = -8x+b

Problem 5: C: 3x-2

Which expression is equivalent to 1/2- (-8)?

postnew [5]

Answer:

1/2 + 8 is equivalent to 1/2 - (-8)

0.5 - (-8) is ALSO equivalent to 1/2 - (-8)

0.5 + 8 is another equation that is equivalent to 1/2 - (-8)

7th Grade Math Need help with both 6 and 7

barxatty [35]

Answer:

Part 6)

case a) $P(odd)=\frac{1}{2}=0.5=50\%$

case b) $P(less\ than\ 3)=\frac{0}{8}=0=0\%$

Part 7)

case a) $P(yellow)=\frac{3}{20}=0.15=15\%$

case b) $P(green\ and\ red)=\frac{1}{20}=0.05=5\%$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

Part 6)

case a) P(odd)

In this problem we have

$x=4$

$y=8$

substitute

$P=\frac{4}{8}=\frac{1}{2}=0.5=50\%$

case b) P (less than 3)

In this problem we have

$x=0$

$y=8$

substitute

$P=\frac{0}{8}=0=0\%$

Part 7)

case a) P(yellow)

In this problem we have

$x=3$

$y=20$

substitute

$P=\frac{3}{20}=0.15=15\%$

case b) P(green and red)

$P(green)=\frac{5}{20}$

$P(red)=\frac{4}{20}$

therefore

$P(green\ and\ red)=\frac{5}{20}*\frac{4}{20}=\frac{20}{400}=\frac{1}{20}=0.05=5\%$

Two identical triangles form a parallelogram with a base of 8 Inches and a height of 6 inches.What is the area of one triangle?

dedylja [7]

Answer: The area of the triangle is 24 square inches

Step-by-step explanation:

Hi, since the 2 triangles form a parallelogram ( see attachment) we have the base and height of the triangles, we have to apply the next formula:

Area of a triangle; (base x height) /2

Replacing with the values:

A = (8x6 )/2

A = 48 /2

A = 24 square inches

The area of the triangle is 24 inches

Feel free to ask for more if needed or if you did not understand something.
