Answer: y intercept (0,-15), x intercept (5,0), yes, (2,-9) is a solution
Step-by-step explanation:
the y intercept is when x=0, so plug in 0 for x -> y=3(0)-15
y=-15, y intercept is (0,-15)
the x intercept is when y=0
so plug in 0 for y -> 0=3x-15
then solve for x,
add 15 to both sides -> 15=3x
divide both sides by 3, 5=x
x intercept is (5, 0)
to test if (2, -9) solution, lets plug in 2 for x and see if we get an answer of -9
so y=3(2)-15
y=6-15
y=-9
so yes, (2,-9) is a real solution

Which of the following is equivalent to log 2 (c)⋅log c (2)
Answer:
1
Step-by-step explanation:
According to law of indices
log a b = 1/ log b a
hence log c (2) = 1/log 2 (c)
log 2 (c)⋅log c (2)
= log 2 (c)⋅ 1/log 2 (c)
= log 2 (c)/log 2 (c)
= 1
Hence the required answer is 1
A full tub of water weighs 3 1/8 pounds. If the tub is filled up only 1/7 full how much would it weigh?
Answer:
[tex]\frac{25}{56}[/tex] pounds
Step-by-step explanation:
By using unitary method,
∵ 1 full tub of water weighs = [tex]3\frac{1}{8}[/tex] pounds
∴ [tex]\frac{1}{7}[/tex] of a water tub will weigh = [tex]3\frac{1}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{(24+1)}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{25}{56}[/tex] pounds
Therefore, water filled in [tex]\frac{1}{7}[/tex]th part of the tub will weigh [tex]\frac{25}{56}[/tex] pounds.
The weight of the tub if filled up to 1/7 full is 25/56 pounds
How to find product of fractionGiven:
Full weight of tub = 31/8 poundsIf filled halfway:
= 1/7 × 3 1/8
= 1/7 × 25/8
= (1 × 25) / (7 × 8)
= 25/56 pounds
Therefore, the weight of the tub if filled to 1/7 of the capacity is 25/56 pounds

What is the y-intercept to (-2,1) (3,-6)
Answer:
(0,-9/5)
Step-by-step explanation:
You can use the equation y=mx+b to solve
First you have to find the slope (m)
You can do this by using the equation y2-y1=x2-x1
(-6-1)/(3--1)= -7/5
m=-7/5
You then use the slope to find out b or the "y-intercept"
I am using the point (-2,1) to substitute
(1)=-7/5(-2)+b
-9/5=b
y=-7/5x-9/5
Check (3,-6):
(-6)=-7/5(3)-9/5
-6=-21/5- 9/5
-6=-6 true
The three angles of a quadrilateral are 55,73,105 what is the fourth angle
Answer:
127°
Step-by-step explanation:
In a quadrilateral, sum of four angles is 360°.
Consider the fourth angle x.
so,
55° + 73° + 105° + x = 360°
x = 360° - 233°
x = 127°
Describe a real-world object that would be measured using square units and another that would be measured using cubic units. Explain.
Answer:
Volume or amount to f water in a jug
The size of a plot of land.
Step-by-step explanation:
The volume of capacity which a certain container can hold such as ; The amount water which can be filled into a cylindrical jug will be measured in cubic units as it requires the multiplication of 3 measured sides of the container ; for a cylinder, radius is squared and multiplied by height. (radius * radius * height).
The size or area of rectangular garden is measured using in square units as it only takes into consideration 2 of the measured parts of a shape.

how many solutions will this quadratic equation x^2+8x+16 has?
Answer:
one solution
Step-by-step explanation:
to find out how many solutions a quadratic equation (with the equation ax²+bx+c) will have, we need to find the discriminant, which is b²-4ac
first, we can label the coefficients as a, b, and c
a=1 (1 is in front of x²)
b=8
c=16
now substitute into the formula
D=(8)²-4(1*16)
D=64-64
D=0
the discriminant is 0
when the discriminant is 0, that means the quadratic equation only has one solution.
Hope this helps!

The rocket ship will travel 2.1 × 10^(y) miles. What is the value of y in the solution?
Answer:
Distance travelled by rocket ship = 2.1 × 10^(6) miles
y = 6
Step-by-step explanation:
1. The written expression;
(1.75 × 10⁴)(1.2 × 10²)
2. The rearranged expression is;
(1.75 × 1.2)(10⁴ × 10²)
3. Let's multiply the coefficient which is the first bracket to get;
2.1(10⁴ × 10²)
4. Applying the product of powers means we will add the powers of ten which are 4 and 2.
Thus; 2.1(10^(4 + 2)) = 2.1 × 10^(6) miles
Comparing to 2.1 × 10^(y), we have;
y = 6

Can someone please help me I’ll give brilliant thingy
Answer:
Yes, the shapes are similar. Note, the angles are equivalent and the sides are scales of each other satisfying the requirements for similarly.
Step-by-step explanation:
For a shape to be similar there are two conditions that must be met. (1) Must have equivalent angles (2) Sides must be related by a scalar.
In the two triangles presented, the first condition is met since each triangle has three angles, 90-53-37.
To test if the sides are scalar, each side must be related to a corresponding side of the other triangle with the same scalar.
9/6 = 3/2
12/8 = 3/2
15/10 = 3/2
Alternatively:
6/9 = 2/3
8/12 = 2/3
10/15 = 2/3
Since the relationship of the sides is the scalar 3/2 (Alternatively 2/3), then we can say the triangles meet the second condition.
Given that both conditions are satisfied, then we can say these triangles are similar.
Note, this is a "special case" right triangle commonly referred to as a 3-4-5 right triangle.
Cheers.
